Magnesium FAQ & Buying Guide

Which form of magnesium is best?

Depends on the goal: bisglycinate is the gentle, highly-absorbed choice for sleep and relaxation; citrate is well absorbed and supports regularity; ZMA pairs magnesium with zinc and B6 for training recovery and sleep. Oxide is the cheapest but least absorbed.

Does magnesium help with sleep?

Magnesium supports the nervous-system wind-down and muscle relaxation that precede sleep — bisglycinate taken 30–60 minutes before bed is the most popular protocol.

Can magnesium stop muscle cramps?

Cramping is a classic low-magnesium sign, especially for athletes who sweat heavily. Magnesium plus proper hydration and electrolytes covers the common causes.

How much magnesium should I take?

Typical supplemental doses are 200–400 mg of elemental magnesium daily, with food or before bed. Split doses if higher amounts loosen your stomach.

Does Fuel Supplements ship magnesium across Canada?

Yes — fast Canada-wide shipping from BC, same-day pickup in Port Coquitlam.
