The Science Behind It

Magnesium is involved in over 300 processes in the body — from muscle relaxation and nervous system function to sleep and energy production. The problem: most supplements use a single, poorly absorbed form like magnesium oxide.

That’s why Advanced Magnesium combines five highly bioavailable forms — citrate, glycinate, malate, taurate and orotate — so your body can actually absorb and use what you take.

Shipping & Returns

We offer tracked shipping on all orders, dispatched within 24 business hours.

UK delivery typically takes 3-5 working days.

Returns are easy — contact info@autoimmuneinstitute.com and we’ll handle everything.

Is It Safe?

Yes — Advanced Magnesium is vegan-friendly, gluten and dairy free, and made in the UK to strict GMP quality standards. Magnesium is generally very well tolerated; a small number of people may notice mild digestive sensitivity, which is usually avoided by taking it with food.

Take it at least 2 hours apart from iron or calcium supplements. Not intended for children or pregnant or breastfeeding women. If you take medication or have a medical condition, consult your doctor before use.

What makes Advanced Magnesium different?

Five highly bioavailable forms of magnesium in one capsule — citrate, glycinate, malate, taurate and orotate — instead of a single cheap form like oxide. Vegan-friendly, gluten and dairy free, and made in the UK to strict GMP quality standards.

Does magnesium really help with sleep and stress?

Magnesium plays a key role in nervous system function and muscle relaxation. Magnesium glycinate in particular is known for its calming effect, and many people notice calmer evenings, less tension and deeper sleep with consistent use.

Why five different forms of magnesium?

Each form is absorbed and used differently: citrate supports muscle relaxation and energy, glycinate supports calm and deep sleep, malate helps with muscle fatigue, taurate supports the heart and stress response, and orotate supports cellular energy production. Together they cover far more than any single form can.

How long until I see results?

Many customers notice calmer evenings and better sleep within 1 to 2 weeks. For the full benefits — muscle tension, energy and stress — use it consistently for 60 to 90 days. You have a full 90 days to decide.

What’s the correct dosage and how should I take it?

Take 1–2 capsules daily with food and a full glass of water — ideally in the evening, when magnesium’s calming effect works with your wind-down routine.

Are there any side effects?

Magnesium is well tolerated by most people. A few may experience mild digestive sensitivity — this can usually be avoided by taking it with food. Always follow the directions on the label.

Is it safe to take with medications?

If you take medication or have a medical condition, speak with your doctor before use. Take magnesium at least 2 hours apart from iron or calcium supplements, as they can compete for absorption. Not intended for children or pregnant or breastfeeding women.

Do I have to subscribe?

No. No subscription, no auto-ship, no ‘cancel before we charge you.’ One order, one payment — and a 90-day money-back guarantee behind it.
