Is a 12-in-1 magnesium complex better than a single form?

Not automatically. A blend covers several forms at once, but each one is dosed lower than a dedicated product. If you want a specific effect, a single well-dosed form such as glycinate is easier to judge.

When should I take it?

The product is pitched for a nightly routine, and magnesium glycinate and taurate are the forms usually taken in the evening. Take it with food if it upsets your stomach.

Will it help with sleep or muscle cramps?

Magnesium supports normal muscle function, and many people take glycinate for relaxation. Evidence for sleep and cramps is mixed, and a blend with small doses of each form may do less than a focused product.

Does it contain oxide, and does that matter?

Most 12-form blends include magnesium oxide. It is cheap and can help regularity, but it is absorbed poorly compared with glycinate or citrate and can cause loose stools in some people.

How much elemental magnesium does each serving give?

The product details do not state the elemental magnesium per serving. Check the supplement facts panel for the amount per capsule and the percent daily value before relying on it.

Can I take it with other supplements or medication?

Magnesium can interact with some antibiotics, diuretics and thyroid medication. Ask a pharmacist or doctor before adding it if you take prescription drugs.
