Buy Magnacell: a next-generation triple-magnesium complex

Magnacell by SIHO combines three complementary forms of magnesium in one 60-capsule formula for optimal absorption throughout the day. Available at our Paris shop, with Click & Collect and delivery across France and Europe.

Why three forms of magnesium

Sucrosomial magnesium uses a patented technology that wraps magnesium in a sucrose lipid matrix for superior intestinal absorption without the digestive discomfort of classic forms. Magnesium malate, bound to malic acid (a Krebs-cycle intermediate), contributes directly to cellular ATP production — well suited to fatigue and muscle recovery. Magnesium taurate, paired with taurine, supports the nervous and cardiovascular systems, easing relaxation, sleep and heart function.

Energy, sleep and recovery

Magnesium is involved in over 300 enzymatic reactions. Adequate intake contributes to the reduction of tiredness via normal energy metabolism, supports normal nervous system function and helps ease irritability and tension, supports normal muscle function and recovery after exercise, and the taurate form supports evening relaxation.

Why SIHO

SIHO is a French brand specialising in premium supplements, packaged in France, with independent lab testing on purity and concentration for each batch, streamlined formulas with no unnecessary additives, and excellent digestive tolerance thanks to the sucrosomial form, which is not known to cause laxative effects.

How to use & precautions

Take 2 capsules a day with a glass of water, with a meal. A 60-capsule pot covers about 1 month; a 2–3 month course is recommended, renewable as magnesium can be taken continuously. Pairs well with ashwagandha KSM-66, vitamin D3 (which supports magnesium absorption) and omega-3.

Do not exceed the recommended daily dose. Not recommended for pregnant or breastfeeding women without medical advice. Store cool and dry.

Frequently asked questions

What is the difference between Magnacell and a standard magnesium bisglycinate?

Bisglycinate is an excellent single form. Magnacell goes further with three complementary forms — sucrosomial (absorption), malate (energy) and taurate (nervous system) — for a more complete complex.

Does Magnacell cause digestive discomfort?

No — that’s one of its strengths. Sucrosomial magnesium is known for excellent digestive tolerance, unlike magnesium oxide or citrate, which can have a laxative effect.
