Magnesium
General Information
Magnesium is a mineral that is involved in many body functions, including maintaining bone strength and keeping the heartbeat steady. About half of the magnesium in our bodies is stored in bones. Magnesium is found in supplements, medications (e.g., antacids, laxatives) and foods, especially foods that are high in fibre (e.g., whole grains, raw leafy green vegetables, almonds, cashews, seafood, and coca).

How is this product usually used?
Magnesium is usually taken by mouth. It is available in different forms, including chewable tablets, capsules, drops, and liquids.
As supplements, magnesium is coupled with another substance or a salt. Some examples are magnesium citrate, magnesium hydroxide, and magnesium oxide. Elemental magnesium refers to the amount of magnesium in each compound.
The dosing range of magnesium supplementation varies for different age groups. The minimum dose reflects about 5% of the highest adequate intake (AI). The maximum daily doses for children and adolescents are based on the tolerable upper intake levels (UL) that apply to magnesium supplements only.
