Potassium: The Mineral That Keeps Your Body Energized, Hydrated & Balanced
This guide breaks down everything you need to know about the mineral that powers your energy, keeps you hydrated, and helps your body stay balanced.
Hey there!
In a world with endless options and information, I’m attempting to translate nutrition and lifestyle based wellness in a simple way, providing well-rounded education with a dose of personal bias. I’ve sifted through the research from a functional view point (think a proactive approach to long-term health), compiling the information that I believe will be the most helpful for you and your health goals; saving you time, energy and money along the way.
Why Potassium Is Worth Prioritizing
Potassium is one of the most essential minerals and electrolytes in the body - yet nearly 98% of Americans don’t get enough on a daily basis. This lack of potassium doesn’t always cause immediate, obvious symptoms. Instead, it often shows up subtly: fatigue, muscle cramps, bloating, or higher blood pressure than usual.
Over time, chronically low potassium can contribute to bigger issues like cardiovascular strain, insulin resistance, or bone loss. The good news? You can correct it, often quickly, with food.
In this guide, we’ll cover:
What potassium is and why your body needs it
The systems and functions potassium supports
Signs and symptoms of low potassium
Food sources and how much you need daily
When (and when not) to use supplements
Lifestyle factors that increase potassium needs
Simple, practical tips to get more each day
🍋 What is Potassium?
Potassium is one of your body’s main electrolytes - about 98% of it lives inside your cells (intracellular), where it helps make energy, keeps fluids balanced, and supports healthy nerve and muscle function. Sodium, on the other hand, is mostly outside your cells. The balance between the two is what keeps things running smoothly.
Unlike some nutrients, your body doesn’t keep a big “backup supply” of potassium. You lose a little every day through urine, sweat, and digestion - which is why getting enough from food on a regular basis is so important.
“Your body can’t store much potassium, so you need a steady supply from food every day to keep your energy, hydration, and muscles working properly.”
What Potassium Does in the Body
-
What it does: Supports the production of ATP (your body’s energy currency) and helps convert food into usable energy (shuttles glucose into cells for fuel)
Deficiency signs: Low potassium can mimic “low blood sugar.” - Persistent fatigue, sluggishness, low exercise endurance, or feeling “drained” even with adequate rest.
-
What it does: Regulates heartbeat and electrical signaling in the heart, relaxes blood vessel walls (vasodilation), and balances sodium to keep blood pressure in check.
Deficiency signs: Irregular heartbeat or palpitations, high blood pressure, swelling or fluid retention, fatigue, or chest discomfort.
-
What it does: Allows muscles (including the heart) to contract and relax properly, prevents cramping, and supports recovery after exercise.
*Athletes and active individuals often need more to replace sweat losses.
Deficiency signs: Muscle weakness, cramps, twitching, stiffness, or feeling sore for longer than usual after activity.
-
What it does: Helps nerve cells send electrical signals, supports cognitive function, and plays a role in mood regulation.
Deficiency signs: Tingling or numbness, brain fog, irritability, mood swings, or even difficulty concentrating.
-
What it does: Maintains fluid balance inside cells, keeps you hydrated at the cellular level, and works with sodium and magnesium to stabilize electrolytes.
Deficiency signs: Dehydration symptoms (thirst, dry mouth, dark urine), dizziness, bloating, or swelling from fluid imbalance.
-
What it does: Potassium helps neutralize excess acid in the body, which protects calcium in bones from being lost through urine. This supports bone density and overall skeletal strength.
Deficiency signs: Increased calcium loss, higher risk of weak or brittle bones over time, potential bone pain, and slower recovery from fractures or injuries.
-
What it does: Potassium supports adrenal gland function and helps the body manage stress by working with sodium and magnesium to maintain proper electrolyte balance. Adequate potassium may also reduce PMS-related bloating and support reproductive health by helping regulate fluid balance and cellular function.
Deficiency signs:
In women: Increased fatigue and stress sensitivity, PMS symptoms like bloating or swelling, irregular menstrual cycles, and potential impacts on fertility or reproductive hormone balance over time.
In men: Low potassium can impair testosterone production and sperm quality.
Potassium isn’t just “another mineral.” It’s a central piece in the puzzle that keeps your muscles strong, heart steady, blood sugar stable, and bones resilient.
Nutrients & Systems That Directly Rely on Potassium
Potassium doesn’t work in isolation - it’s part of a much bigger team effort. Think of it as one player in your body’s electrolyte “orchestra.” Here’s how it interacts with other nutrients and systems:
-
Potassium and sodium are like yin and yang.
Too much sodium without enough potassium can raise blood pressure, strain the heart, and throw off hydration.
A higher-potassium diet naturally helps balance sodium’s effects, lowering cardiovascular risk.
-
Magnesium and potassium are best friends in muscle and nerve function.
Without enough magnesium, your body can actually struggle to hold onto potassium. (This is why some people don’t feel better until they raise both.)
-
Potassium helps regulate calcium excretion in urine.
A low-potassium, high-salt diet can lead to calcium loss and weaker bones over time.
-
Adequate potassium is linked with better insulin sensitivity.
Low potassium can make it harder for your cells to absorb glucose, leading to blood sugar spikes, fatigue, and increased risk for metabolic issues.
-
Potassium works with sodium and magnesium to keep the adrenals stable.
Chronic stress raises cortisol, which increases potassium losses.
Low potassium can leave you feeling more “wired but tired” after stress.
-
Every heartbeat depends on the balance of sodium, potassium, calcium, and magnesium moving across cell membranes.
Without potassium, heart rhythm disturbances (arrhythmias) become more likely.
Nutrients & Systems that Potassium Directly Relies On
Potassium is deeply interconnected with other nutrients, hormones, and body systems. Supporting these systems helps ensure your potassium stays in balance and performs its critical roles in energy, heart, muscle, and nerve function.
-
Role: Aldosterone regulates sodium and potassium balance; cortisol impacts adrenal stress responses.
Impact on potassium: Chronic stress or high cortisol → increased aldosterone → potassium (and magnesium, calcium, sodium) is lost in urine, depleting intracellular stores.
Functional tip: Manage stress, support adrenal health with adequate protein, fat, and electrolytes to preserve potassium.
-
Role: Maintains acid-base balance and resting membrane potentials in cells.
Impact on potassium: Adequate CO₂ prevents leakage of potassium, sodium, calcium, and magnesium from cells, stabilizing nerve and muscle function.
Functional tip: Balanced carbohydrate intake supports CO₂ production because glucose metabolism generates CO₂, which helps maintain cellular electrical gradients. Proper CO₂ levels support potassium retention and movement into cells. Combine this with oxygenation and breathing practices to optimize electrolyte balance.
-
Role: Essential cofactor for over 300 enzymes, supports nerve and muscle function.
Impact on potassium: Required for cellular potassium transport; low magnesium can lead to potassium deficiency symptoms even if intake is sufficient.
Functional tip: Pair potassium-rich foods with magnesium-rich foods like leafy greens, nuts, seeds, and legumes.
-
Role: Works in tandem with potassium to maintain fluid balance and nerve/muscle function.
Impact on potassium: High sodium intake → increased potassium excretion; low sodium → potassium retention. Balance is key.
Functional tip: Favor whole-food sodium sources and reduce highly processed foods to maintain electrolyte harmony.
-
Role: Vital for muscle contraction, nerve signaling, and bone health.
Impact on potassium: Calcium and potassium together regulate cell excitability and muscle contractions. Imbalances can affect heart rhythm and muscle function.
Functional tip: Include calcium-rich foods alongside potassium (dairy, leafy greens, canned fish with bones).
-
Role: Glucose metabolism produces the energy (ATP) needed for the Na⁺/K⁺ pump (a protein pump embedded in the cell membrane), which moves potassium into cells. Insulin helps glucose get into cells, but the energy from glucose is what actually drives potassium uptake.
Impact on Potassium: If glucose metabolism is impaired (from low carb intake, insulin resistance, or metabolic issues), potassium can’t enter cells efficiently, even if you eat enough. This can cause muscle weakness, fatigue, and poor nerve signaling.
Functional Tip: Pair potassium-rich foods with natural carbohydrate sources like fruits, starchy vegetables, or root vegetables. This supports glucose metabolism and insulin function, helping potassium move into cells effectively. Focus on nutrient-dense carbs rather than refined sugars for stable energy and better mineral balance.
-
Role: Filter blood, maintain potassium balance, and excrete excess potassium.
Impact on potassium: Kidney dysfunction → impaired potassium excretion → risk of hyperkalemia.
Functional tip: Stay hydrated, support kidney function with adequate electrolytes, and monitor potassium levels if kidney health is compromised.
-
Role: Regulates metabolic rate and energy production.
Impact on potassium: Low thyroid function → impaired cellular potassium uptake → reduced energy, muscle weakness, and fluid imbalance.
Functional tip: Support thyroid health with adequate protein, selenium, and iodine.
-
Role: Absorbs potassium and other minerals from food.
Impact on potassium: Low stomach acid, gut dysbiosis, or malabsorption → less potassium absorbed, even if dietary intake is sufficient.
Functional tip: Support digestion with probiotics, enzyme-rich foods, and adequate protein.
-
Role: Maintains oxygen and CO₂ levels.
Impact on potassium: Impaired respiration or chronic shallow breathing → lower CO₂ → potassium shifts out of cells, affecting nerve and muscle function.
Functional tip: Practice deep breathing, regular movement, and cardiovascular conditioning to support healthy gas exchange and potassium balance.
Potassium depends on a network of nutrients and systems - adrenal hormones, CO₂, magnesium, sodium, calcium, insulin, kidneys, thyroid, digestive, and respiratory function - to move into cells and maintain proper balance. Supporting these systems with stress management, hydration, balanced carbohydrates, whole foods, and healthy metabolism ensures potassium can fuel energy, nerve signaling, heart, and muscle function efficiently.”
Lifestyle & Environmental Factors That Influence Potassium
Potassium levels aren’t just about what you eat - your daily habits, environment, and stress levels can all impact how well your body retains and uses this mineral.
Factors That Increase Potassium Loss or Need
High-sodium or processed diets
Excess sodium forces your kidneys to excrete more potassium to maintain the sodium-potassium balance.
From a functional perspective, this engages the renin-angiotensin-aldosterone system (RAAS), influencing blood pressure, adrenal hormone regulation, and even how the liver handles cholesterol and glucose metabolism.
Chronic high-sodium intake can increase potassium needs and strain cardiovascular and adrenal systems.
Sweating & exercise
Intense workouts, hot climates, or frequent sauna use increase potassium loss through sweat.
Athletes and active individuals often need more potassium to prevent cramping, maintain muscle function, and support adrenal health.
Chronic stress
Elevated cortisol levels increase urinary potassium loss.
Stress also affects sodium balance and fluid regulation, making potassium even more critical for nerve, muscle, and heart function.
Caffeine & alcohol
Both substances increase urinary potassium excretion.
Over time, habitual use without dietary compensation can lead to functional potassium deficiency.
Medications
Certain diuretics, corticosteroids, and some blood pressure medications increase potassium loss.
Functional practitioners often monitor potassium alongside magnesium and sodium to support cellular and adrenal balance.
Illness or digestive issues:
Vomiting, diarrhea, or malabsorption reduces potassium absorption and increases losses.
Maintaining gut health supports electrolyte balance and overall mineral uptake.
Factors That Support Potassium Absorption & Utilization
Balanced magnesium intake: Magnesium helps your body hold onto potassium and supports muscle and nerve function.
Adequate hydration: Water supports proper cellular function and potassium transport.
Whole-food diet: Whole foods provide synergistic nutrients (magnesium, calcium, antioxidants) that enhance absorption.
Reduced processed foods: Minimizing highly processed foods helps maintain the sodium-potassium balance.
Healthy gut function: A healthy microbiome can improve mineral absorption, including potassium.
Stress management: Supporting adrenal function ensures potassium and sodium are balanced for heart, muscle, and nerve health.
“Potassium is a team player. Your diet, lifestyle, stress levels, and adrenal health all influence how much your body retains and uses - getting it from whole foods while supporting your stress response and hydration is key to optimal energy, heart, and muscle function.”
Top Whole-Food Sources of Potassium
Focusing on whole, real foods gives your body potassium in a form it can actually use; as well as fiber, antioxidants, and other nutrients that support your heart, muscles, and brain.

Tips for Maximizing Potassium from Fruits
Go for ripe fruit: The riper the fruit, the richer it tends to be in potassium and simple sugars that help your body use it efficiently. A perfectly ripe banana or orange isn’t just sweeter - it’s more nourishing on a cellular level.
Pair it smartly: Enjoy fruit with a little protein or fat (like yogurt, cheese, or eggs) to steady your blood sugar and help your body hold on to those minerals longer.
Sip your potassium: Fresh-squeezed orange juice or coconut water can be an amazing ways to hydrate and get easily absorbable potassium. Minimize the bottled “fruit drinks” with preservatives or added syrups - they don’t deliver the same benefit.
Don’t fear the sugar - it’s part of the magic: Natural fruit sugar actually helps potassium enter your cells. When you eat fruit (or sip juice), your body releases a little insulin - and insulin’s job is to carry both glucose and potassium inside your cells, where they create energy. So when it’s from whole fruit or fresh juice, sugar isn’t something to avoid; it’s part of the process that helps your body thrive.
Mix it up: Rotate your fruits - citrus, tropical, and even dried options - to get a balance of potassium, magnesium, and other supportive nutrients. Each type adds something unique to your mineral mix.
💡 Functional Takeaway
“Ripe fruits and fresh fruit drinks are a powerful, natural way to boost potassium and cellular energy. Pair them with protein, healthy fats, and other mineral-rich foods to maximize absorption, support blood sugar balance, and help your body use potassium efficiently.”

Tips for Maximizing Potassium from Vegetables
Choose fresh and in-season: Fresh, in-season vegetables tend to retain the most potassium and cofactors like magnesium and chlorophyll. Ripe, colorful produce also supports better nutrient absorption.
Cook to preserve nutrients: Potassium is water-soluble, so avoid over-boiling. Instead:
Steam, roast, or sauté to soften fibers while keeping potassium intact.
If you boil veggies, you can save the water to use in soups or sauces - you’ll retain those minerals.
Pair with fat and a pinch of salt: Healthy fats (like olive oil, butter, or coconut oil) improve absorption of fat-soluble vitamins, which help potassium do its job. A small pinch of mineral-rich salt can also help balance electrolytes.
Combine with vitamin C and magnesium-rich foods: Vitamin C (peppers, citrus, tomatoes) and magnesium (spinach, squash) support potassium’s movement into cells for energy, muscle, and nerve function.
Eat a rainbow of veggies.
Greens: Spinach, kale, Swiss chard → magnesium and chlorophyll
Oranges/yellows: Sweet potatoes, carrots, squash → beta-carotene for antioxidants
Reds/purples: Beets, peppers → support circulation and detox pathways
Don’t fear the starches: Root vegetables like potatoes and sweet potatoes are potassium-rich and support thyroid, adrenal, and metabolic function. Pair with protein and fat for steady energy.
Use mineral-rich cooking liquids: Bone broth or veggie stock can boost potassium and other electrolytes when cooking greens or roots.
💡 Functional Takeaway
“Maximize potassium from vegetables by choosing fresh, colorful produce, cooking gently, pairing with fat and minerals, and combining with vitamin C and magnesium-rich foods. These small tweaks support energy, hydration, and hormone balance naturally.”

Tips for Maximizing Potassium from Beans & Dairy
Beans
Beans can be tricky for some people, but with the right prep, they can be a great, nutrient-dense potassium source.
Soak & sprout: Soaking beans overnight (or longer) helps reduce phytic acid and lectins, which can block mineral absorption. Adding a splash of vinegar or lemon juice to the soaking water helps even more.
Cook slowly & thoroughly: Pressure cooking or slow simmering makes beans gentler on digestion while keeping potassium intact.
Pair with vitamin C foods: Think beans with tomatoes, citrus, or bell peppers - vitamin C helps improve mineral absorption, including potassium.
Rotate varieties: Black beans, lentils, and white beans each bring slightly different nutrient profiles. Mixing it up keeps your gut diverse and your nutrient intake balanced.
Dairy
Choose high-quality dairy: Grass-fed and organic milk, yogurt, and kefir not only provide potassium but also other vitamins, minerals and healthy fats that support electrolyte balance.
Prioritize raw or low-temp pasteurized and non-homogenized options when possible for better enzyme activity and nutrient retention.
Pair with fruit: A glass of milk with orange slices (or orange juice), or a bowl of yogurt with berries is a great combo - the carbs help shuttle potassium into your cells.
Watch sodium balance: High-quality dairy naturally supports hydration and adrenal function, especially when sodium intake is balanced.
Rotate dairy types.Kefir, yogurt, and milk all provide slightly different probiotic, vitamin, and mineral profiles - mixing them enhances overall nutrient intake.
💡 Functional Takeaway
“Maximize potassium from beans and dairy by soaking and rotating beans, pairing them with vitamin C foods, choosing high-quality dairy, and combining with fruit for optimal absorption. This supports energy, digestion, and electrolyte balance throughout the day.”

Tips for Maximizing Potassium from Meat, Poultry & Seafood
Choose fresh, minimally processed proteins: Grass-fed beef, pasture-raised poultry, and wild-caught seafood retain more nutrients and are lower in sodium. Excess sodium from processed meats can increase potassium loss.
Rotate cuts and types.
Lean cuts (chicken breast, sirloin) → potassium and high-quality protein.
Fatty cuts (ribeye, chicken thighs with skin) → support hormone production and absorption of fat-soluble vitamins.
Organ meats (liver, heart) → rich in B vitamins, CoQ10, and trace minerals.
Seafood & shellfish → highly bioavailable potassium, selenium, iodine, and zinc.
Cook gently: Potassium is water-soluble, so avoid overboiling. Use roasting, braising, steaming, or pan-searing to preserve minerals. If you cook in water or broth, reuse the liquid in sauces or soups to capture potassium and collagen.
Pair with potassium-rich plant foods: Combine meats with vegetables, fruits, or starchy plants to boost overall potassium intake. Example: salmon + roasted sweet potato + spinach.
Include fat for nutrient synergy: Fat helps absorb fat-soluble vitamins (A, D, E, K) that support potassium utilization. Examples: drizzle butter over cooked veggies and meat, or use olive oil when sautéing.
Balance electrolytes: Including magnesium- and sodium-rich foods alongside potassium-rich meats improves cellular hydration, muscle function, and adrenal health.
Rotate cooking methods: Varying your cooking styles (braising, roasting, steaming) helps preserve different nutrients while keeping meals interesting.
💡 Functional Takeaway
“Maximize potassium from meat, poultry, and seafood by choosing fresh, high-quality proteins, rotating cuts, cooking gently, pairing with plant foods, and including fat and electrolytes. These strategies help your body absorb potassium efficiently, supporting energy, muscle, hormone, and nervous-system health.”

Electrolytes & Supplement Recommendations
While most people get enough potassium from whole foods, there are situations where electrolyte support can be helpful - during intense exercise, heat exposure, stress, or low-carb/high-sweat days. Balanced electrolyte supplements are usually safer and more effective than potassium-only pills.
Includes clickable links to trusted brands and discounts when applicable.
High-Quality Electrolyte Blends (Primary Recommendation)
Why: Balanced blends provide potassium, magnesium, sodium, and sometimes calcium, supporting hydration, nerve function, muscle contraction, and energy.
Formats:
Powders: Mix in water; typically 200-500 mg potassium per serving alongside magnesium and sodium.
Mineral drops: Concentrated trace minerals added to water; allows flexible dosing.
Ready-to-drink beverages: Convenient for on-the-go hydration.
Functional Tip: Use during workouts, long days in heat, or periods of higher electrolyte loss. These are support tools, not replacements for potassium-rich foods.
Recommended Electrolyte Brands
These brands offer balanced minerals, (mainly) clean ingredients, and practical carbohydrate content:

Potassium
More bioavailable sources:
Potassium citrate: Easily absorbed, gentle on digestion.
Potassium chloride: Common and effective source for electrolyte balance.
Potassium bicarbonate: Supports acid-base balance; good in small doses.
Potassium phosphorous:
Potassium iodide
Less ideal / minimize:
Potassium gluconate: Lower potency; not as efficiently absorbed.
Artificially flavored potassium blends: Often paired with artificial sweeteners or fillers.
Practical Tips for Using Electrolytes
Pair electrolytes with water and meals for optimal absorption.
Use supplements strategically - during high sweat loss, low-carb days, or heavy exercise - not daily by default.
Prioritize whole-food sources like fruits, vegetables, beans, and dairy.
Check labels for unnecessary additives and adjust to your body’s response.
For most people, whole foods provide plenty of potassium. Balanced electrolyte supplements are a safer, more practical way to support hydration, energy, and mineral balance. Potassium-only pills are mostly educational and should only be used under medical supervision. Focus on food first, use electrolytes strategically, and your potassium will stay in balance naturally.
Who Should Be Careful With Potassium
Potassium is essential, but too little or too much can cause serious issues - especially for certain populations. Here’s a clear guide.
1. Kidney Disease or Impaired Kidney Function
The kidneys regulate potassium. Reduced kidney function can lead to hyperkalemia (dangerously high potassium).
Recommendation: Monitor potassium intake carefully, prioritize whole-food sources, and get regular blood tests.
2. Heart Conditions
People with arrhythmias or other cardiac issues are particularly sensitive to potassium imbalances.
Too little potassium can trigger palpitations and irregular heartbeats.
Too much potassium, especially from supplements, can also be life-threatening.
3. Medications That Affect Potassium
ACE inhibitors or ARBs (blood pressure medications)
Potassium-sparing diuretics (like spironolactone)
NSAIDs (ibuprofen, naproxen)
These medications can raise potassium levels or interfere with excretion.
Recommendation: Always check with your doctor before taking potassium supplements.
4. Adrenal Insufficiency (Addison’s Disease)
Aldosterone helps balance sodium and potassium. Low adrenal function can increase potassium levels.
Recommendation: Monitor electrolytes and work with a healthcare provider.
5. Gout
Whole-food potassium sources (fruits, vegetables, dairy) are generally safe and may help reduce uric acid.
High-dose potassium supplements can be risky if kidney function is impaired.
Recommendation: Focus on foods, stay well-hydrated, and get kidney function tested if supplementing.
6. Other High-Risk Situations
Severe dehydration
Excessive use of potassium-containing salt substitutes
Certain metabolic disorders affecting electrolyte balance
What’s Not Recommended
High-dose potassium supplements without supervision
Salt substitutes that are mostly potassium chloride in at-risk populations
Ignoring kidney, heart, or adrenal function when increasing potassium intake
Signs of Low or High Potassium
Low Potassium (Hypokalemia):
Muscle cramps or weakness
Fatigue
Constipation
Palpitations or irregular heartbeat
Mood changes or mental fog
High Potassium (Hyperkalemia):
Nausea or vomiting
Muscle weakness or tingling
Abnormal or slow heartbeat
In severe cases: cardiac arrest
“Potassium is vital for energy, heart, muscle, and nerve health - but balance is everything. Most people get enough from food, but those with kidney issues, heart conditions, adrenal problems, gout, or on certain medications need extra caution. Focus on whole-food sources, hydrate well, and monitor blood levels when necessary to keep potassium safe and effective.”
How Much Do You Need?
Potassium requirements depend on age, sex, and life stage. Getting enough is crucial for heart, muscle, nerve, and metabolic health.
1. FDA / Standard Recommendations
Adults (and pregnant women): 4,700mg per day (from food)
Children & teens: 2,500-3,800mg per day (depending on age)
Note: The FDA sets this as a daily adequate intake, based primarily on maintaining normal blood pressure and heart function. Most people do not meet this intake, as diets often lean heavily on processed foods low in potassium.
2. Functional Perspective: 4,700-5,000mg per day (from food)
Here’s why this functional target is a bit higher than the FDA minimum:
Supports optimal cellular function: Potassium is critical for maintaining the electrical gradients inside cells, helping muscles, nerves, and the heart work efficiently.
Balances sodium intake: Most modern diets are high in sodium, which increases potassium needs to maintain proper electrolyte balance.
Supports metabolic energy: Adequate potassium helps thyroid and adrenal function, supporting overall energy production.
Hydration & kidney function: Higher intake from foods (rather than supplements) helps maintain fluid balance and kidney efficiency.
Optimal potassium intake may vary based on:
Activity level: Sweating during exercise increases potassium losses.
Sodium intake: High sodium diets increase potassium needs because your body excretes more potassium to maintain electrolyte balance.
Stress & adrenal function: Chronic stress or adrenal fatigue may increase potassium requirements.
Hormone balance: Proper thyroid and insulin function support potassium movement into cells.
Quick Tips to Reach Daily Potassium
Include 2–3 servings of potassium-rich vegetables and fruits per meal.
Add dairy, beans, and moderate meat or seafood.
Consider fruit, coconut water beverages, or electrolyte drinks/packets for hydration and extra potassium.
Track your intake using a food diary or nutrition app (I enjoy Cronomoter) if you want to ensure you hit functional targets (often above 4,700 mg/day for active adults).
Final Takeaway
Potassium is a quiet hero - regulating your energy, hydration, heart health, mood, and muscle function day in and day out. Most of us are running on less than half of what we need, but with simple food swaps, you can easily bridge the gap.
If you want to feel more energized, balanced, and resilient, make potassium-rich foods a regular part of your daily meals. Your body (and your future self) will thank you.
Happy health,
Aria
