Frequently Asked Questions (FAQs)

1. What does magnesium capsules do for your body?

Magnesium plays many crucial roles in the body, such as supporting muscle and nerve function and energy production. Low magnesium levels usually don't cause symptoms. However, chronically low levels can increase the risk of high blood pressure, heart disease, type 2 diabetes and osteoporosis.

2. Which is the best form of magnesium to take?

Orally, magnesium citrate is the best absorbed form (but it's bonded to a big molecule so there is a smaller amount of magnesium by weight). Mg oxide is the most poorly absorbed form but has the highest Mg per weight, so actually you may get more elemental magnesium out of the same dose of Mg oxide vs.

3. When should I take magnesium capsule?

Therefore, magnesium supplements can be taken at any time of the day, as long as you're able to take them consistently. For some, taking supplements first thing in the morning may be easiest, while others may find that taking them with dinner or just before bed works well for them.

4. What kind of magnesium supplement is best absorbed?

Research has found that magnesium glycinate is one of the most absorbable forms, along with citrate, chloride, lactate, and aspartate. It is also important to note that zinc and calcium can reduce magnesium's absorption, so be mindful of what you take it with.
