Can You Take Magnesium and Potassium Together?

magnesium and potassium can be taken together

Magnesium, an essential nutrient involved in over 300 enzyme reactions, including those crucial for energy production and DNA synthesis, promotes bone strength, sleep quality, and stress reduction, per Dr. Carolyn Dean, MD ND's insights in her book The Magnesium Miracle

The adult body typically houses around 25g of magnesium - 50% to 60% residing within bones while the rest lies in soft tissues; serum levels contribute less than 1% but are tightly controlled at normal concentrations between 0.75-0.95mmol/L.

According to Harvard Medical School, potassium contributes significantly to maintaining cellular fluid balance and facilitates proper nerve transmission for muscle function. 

While a definitive Recommended Daily Allowance (RDA) for potassium is lacking due to data paucity, it's widely considered that consumptions amounting to roughly 3,400 mg (males) or 2,600 mg(females) cater suitably to the nutritional needs of individuals above age 19.

Benefit of Magnesium

Magnesium is a crucial mineral, essential to numerous bodily functions like bone maintenance and cardiovascular health. Key benefits of magnesium consumption include:

Heart Health: The European Journal of Clinical Nutrition says high dietary magnesium intake lowers hypertension risks.

Bone Strength: Research indicates an increased dietary Magnesium leads to higher bone density, particularly in women, suggesting preventive roles in osteoporosis. 

Mental Well-being: Researches highlight that significantly lower serum levels of magnesium among depressed patients - implying possible connections towards mental wellness enhancement through appropriate magnesian nourishment

Blood Sugar Control: The pivotal DASH diet emphasizes consuming food rich in minerals like potassium and calcium, and notably, MAGNESIUM, which led Diabetes Care to report reduced instance rates among diabetes type II patients.

Magnesium (Glycinate), Magnesium Taurate, and Magnesium Ascorbate are some of the magnesium supplements available at Welzo.

Benefits of Potassium

Potassium, an essential nutrient, plays a pivotal role in the smooth functioning of many critical biological processes. Here are various benefits of potassium:

Maintains Heart Health: Studies published in the Hypertension Journal corroborate that potassium intake helps lower blood pressure.

Regulates Fluid Balance and Nerve Transmission: It ensures optimum nerve transmission, which is essential for muscle performance and heart function.

Supports Kidney Function: Higher dietary potassium aids kidneys in the filtration of waste, thereby preventing kidney stones.

Preserve Bone Density: The alkaline nature of potassium neutralizes acid load, reducing calcium loss from bones, which often underpins osteoporosis causation; substantiated further via multiple studies like that reported by the American Journal Of Clinical Nutrition.

Potassium supplements you can use include Potassium Citrate, Potassium Gluconate, and Potassium Iodide.

Can You Take Magnesium And Potassium Together?

Yes, it is safe and advantageous to take magnesium and potassium together. These electrolytes play critical roles in the body's energy production, as per cardiovascular scientist Dr. James DiNicolantonio. Low levels might result in cardiac issues, whereas optimal amounts ensure proper nerve transmission and muscle functions, including heart rhythms. A diet rich in Mg+K promotes extensive benefits, leading to overall well-being enhancement.

The best magnesium and potassium supplements you can use include Magnesium & Potassium Aspartate and Potassium Magnesium (citrate).

Benefits of Taking Magnesium And Potassium Together

Indeed, the synergistic intake of magnesium and potassium offers several health benefits. 

Improved Heart Health

Both minerals contribute to optimal cardiovascular function. As Dr.James DiNicolantonio, a renowned cardiovascular research scientist, rightly pointed out, balanced levels ensure consistent heart rhythms while aiding in preventing cardiac dysfunctions.

Better Muscle Function

These nutrients are vital for proper muscle contraction and relaxation cycles, including those of our primary muscle, the heart. 

Electrolyte Balance Maintenance

Optimal body hydration stems from efficient electrolyte balance maintenance prominently featuring both Mg+K - integral parts, hoped-for-body-hydration-equation

Enhanced Nerve Transmission

Combined consumption promotes enhanced nerve transmission, a critical process facilitating effective communication between the brain and other body organs.

Bone Health Promotion

The combined impact aids in maintaining bone density over time attributed to their alkaline nature neutralizing acid, thereby reducing chances of osteoporosis incidence based on studies like that reported by American Journal-Clinical Nutrition indicating inversely proportional relationship potential bone turnover rates, Mg+K dietary adjustments.

Reduced Cramp Incidences     

Here's where adept management of both these elements realizes its full worth, ensuring fewer such incidences are confirmed.

Potential Risks And Side Effects

Despite the benefits of taking magnesium and potassium together, it is worth noting the potential risks and adverse effects associated with their combined use. Here are some important considerations:

Electrolyte Imbalance: Overconsumption might lead to an electrolyte imbalance, which can cause nausea, irregular heartbeat or muscle weakness.

Laxative Effect: High magnesium doses often lead to a laxative effect, leading to diarrhea.

Kidney Damage: Individuals with kidney disorders need to exercise caution since the kidneys regulate these minerals. Excess intake could exacerbate problems, causing serious health concerns.

Drug Interactions: Often overlooked but magnified within individuals consuming specific medications - blood pressure drugs/antibiotics/water pills interact adversely at times, significantly altering drug effectiveness.

Overdose Symptoms: Accidental overdose situations, though rare, induce symptoms including:

  • Fatigue
  • Muscle Weakness
  • Hypotension (low Blood Pressure)

In light of such plausible complications, personalized assessment from healthcare professionals becomes crucial before initiating any supplement regimens involving magnesium and potassium, ensuring one reaps collective benefits sans associated drawbacks and aligns intake patterns safely.


When ingested in harmony, magnesium and potassium bring immense health benefits. They support heart health, enhance muscle function and contribute to bone density maintenance, among other advantages. Adherence to precise dosages is crucial in circumventing risks like electrolyte imbalance or kidney damage. Therefore, expert medical guidance for safely consuming these essential minerals becomes necessary.

Frequently Asked Questions
