Magnesium was just features in my Adrenal Fatigue Series for it’s role in enzymatic reactions related to the adrenal cascade. Mostly known for it’s role in sleep aides, and the relationship with calcium. magnesium comes in several varieties including magnesium oxide, magnesium chelates and magnesium citrate. Robb Wolf recommends the citrate form for it’s apparent ease of absorption. Charles Poliquin prefers the chelated form due to the varied compositions creating a time release effect.
Aside from the role in enzymatic reactions, magnesium has an influence in blood clotting, energy production, muscle contraction and nerve transmission. Deficiencies play a role in insulin resistance, chronic fatigue (adrenal fatigue) and high blood pressure.
Robb Wolf recommends 1200 mg-2000 mg a day. Robb goes on to suggest that the heavy doses of dairy and grains have displaced fruit and veggies in the modern western diet. Even though this modern diet entails greater consumption of calcium the lack of magnesium (fruits and veggies, paticularly dark green veggies) greatly reduces the potential absorption of all this extra calcium.
