What does Magnesium do for the body?

Magnesium is an abundant mineral that functions as a cofactor in over 300 enzymatic reactions in the body.

Some of these biochemical reactions include blood pressure and blood sugar regulation, nerve and muscle function, and protein synthesis.

Energy production, healthy bone development, DNA and RNA synthesis, normal heart rhythms, nerve impulses, and muscle contractions are also part of where Magnesium plays a role in the body.

 

What does Potassium do for the body?

Potassium's roles are essential for a balanced and well-functioning body.

Potassium is an electrolyte mineral that helps maintain proper water balance in your cells, it also plays a role in muscle contractions, electrical nerve transmissions, and healthy kidney function.

A potassium deficiency can develop due to a number of reasons including: excessive vomiting, diarrhea, sweating, starvation, laxatives, diuretics, and kidney dialysis.

Why some people use Magnesium and Potassium supplements

If you try to eat a healthy diet with a variety of foods to hit your nutritional targets, but still seem to have inadequate levels of Magnesium and Potassium, your doctor may recommend supplements to help bridge the gap and get your levels within range.

Supplementation may also be a good idea for people who have certain health conditions or take medications that make Magnesium and Potassium nutritional deficiencies more likely.

Talk with your doctor about your supplementation needs for these two nutrients.

 

Can you take Magnesium and Potassium supplements together?

Not only can you take Magnesium and Potassium supplements together, it may actually be a very smart idea.

Potassium and Magnesium can be common deficiencies in the general population, so supplementing with both at once may be a good way to correct both issues.

Also, they work closely in the body with each other.

Studies have found that disturbances in Magnesium levels can even lead to the depletion of Potassium. This may have to do with increased membrane permeability when there is not enough Magnesium, causing the intracellular Potassium to "leak out" of the cell and be excreted in the urine.

However, if you do not have a deficiency in these nutrients, you do not want to over-supplement as there can be negative side effects associated with taking too much Magnesium or Potassium.

Talk with your doctor so that they can review your levels, other conditions, and current medications, and see if Magnesium and Potassium supplements are a good fit for you.

 

How much Magnesium and Potassium should you take?

Potassium:

The adequate daily dietary intakes recommended for Potassium differ between adult males and adult females.

For adult males over 19 years of age, an intake of 3,400mg (3.4gm) is recommended.

For adult females over 19 years old, they need an intake of 2,600mg (2.6gm).

 

When looking into a Potassium supplement, it is normal to see strengths of about 80mg of Potassium in a multivitamin formula, or up to 99mg in a Potassium-only supplement.

 

Magnesium:

The recommended dietary allowance for Magnesium is also slightly different between adult males and females.

For adult males over the age of 19, the daily intake is recommended to be between 400mg-420mg.

For adult females over 19, the daily intake should be between 310mg-320mg.

 

Also note: The recommended amounts of Potassium and Magnesium also change during pregnancy and breastfeeding for women.
