Healthy kidneys help regulate magnesium levels in the body.

However, there is no evidence that magnesium supplements can “boost” kidney function in healthy individuals or repair damaged kidneys.

People with chronic kidney disease should be especially cautious with magnesium supplements because impaired kidneys may not remove excess magnesium effectively, potentially leading to dangerously high blood magnesium levels.

Can Magnesium Flush Out Uric Acid?

Magnesium is not a proven treatment for high uric acid or gout.

While maintaining good hydration, a balanced diet, and a healthy weight can help manage uric acid levels, magnesium has not been shown to significantly “flush out” uric acid from the body.

Anyone with recurrent gout or elevated uric acid should consult a healthcare provider for appropriate evaluation and treatment.

Does Magnesium Restore Memory?

Magnesium is important for normal brain function, and a deficiency may affect concentration or cognitive performance.

However, there is no reliable scientific evidence that magnesium can restore lost memory or cure dementia or Alzheimer’s disease.

Researchers continue to study its role in brain health, but more evidence is needed.

Signs of Magnesium Deficiency

Low magnesium levels may cause:

• Muscle cramps
• Fatigue
• Weakness
• Numbness or tingling
• Irregular heartbeat
• Loss of appetite
• Nausea

Only a healthcare professional can determine whether supplementation is appropriate.

Should You Take a Magnesium Supplement?

Some people may benefit from supplements if they have a confirmed deficiency or certain medical conditions. However, supplements are not necessary for everyone.

Always speak with a healthcare provider before starting magnesium supplements if you:

• Have kidney disease
• Take medications for blood pressure or heart conditions
• Use antibiotics or diuretics
• Are pregnant or breastfeeding

Possible Side Effects

Large doses of magnesium supplements can cause:

• Diarrhea
• Stomach cramps
• Nausea

Very high doses—especially in people with kidney disease—can lead to dangerously high magnesium levels, which may cause low blood pressure, confusion, muscle weakness, or heart rhythm problems.

Tips for Maintaining Healthy Magnesium Levels

• Eat plenty of leafy green vegetables.
• Include nuts and seeds in your diet.
• Choose whole grains over refined grains.
• Stay physically active.
• Drink enough water each day.
• Limit highly processed foods.

Final Thoughts

Magnesium is an essential mineral that supports muscle function, heart health, bone strength, energy production, and normal nerve function. Eating magnesium-rich foods is an excellent way to support overall wellness.

However, claims that magnesium boosts kidney function, flushes out uric acid, or restores memory naturally are not supported by strong scientific evidence. While magnesium is important for good health, it is not a miracle cure. If you think you may have a magnesium deficiency or are considering supplements, consult a healthcare professional to determine what is appropriate for your individual needs
