Natural Compound

Magnesium Citrate

Contributes to normal muscle and nerve function, energy-yielding metabolism, and the reduction of tiredness and fatigue. A highly bioavailable form.

Key Function

Muscle and nerve function, energy production, bone health.

What it's used for

Magnesium supplementation for muscle, nerve, and energy support.

Key Benefits

Contributes to normal muscle and nerve function, energy-yielding metabolism, and the reduction of tiredness and fatigue. A highly bioavailable form.

Science Behind It

Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body. It contributes to normal muscle function, nerve transmission, protein synthesis, and energy-yielding metabolism (ATP). Magnesium citrate is a highly bioavailable form, meaning it is well absorbed by the body.

Capsule Shell

Protects ingredients from degradation, masks taste/odor, convenient dosage form, allows for specific release profiles.

Key Function

Enclosure for active ingredients, protects contents.

What it's used for

To encapsulate powdered or liquid supplements for oral administration.

Key Benefits

Protects ingredients from degradation, masks taste/odor, convenient dosage form, allows for specific release profiles.

Science Behind It

Capsule shells are typically made from gelatin (animal-derived protein) or hypromellose (HPMC, plant-derived cellulose polymer). They dissolve in the digestive tract, releasing the active ingredients. They protect the encapsulated ingredients from environmental factors like moisture and oxygen, and also mask unpleasant tastes or odors.

Microcrystalline Cellulose

Acts as a fiber (though typically in small amounts in supplements), provides structure to tablets, generally recognized as safe.

Key Function

Bulking agent, binder, disintegrant.

What it's used for

Pharmaceutical and food additive, mainly as an excipient in tablets and capsules.

Key Benefits

Acts as a fiber (though typically in small amounts in supplements), provides structure to tablets, generally recognized as safe.

Science Behind It

Microcrystalline cellulose (MCC) is a purified, partially depolymerized cellulose. It's an inert, insoluble dietary fiber that is not digested or absorbed by the body. In supplement formulations, its primary role is as a binder to hold ingredients together, a filler or bulking agent to increase tablet size, and a disintegrant to help tablets break down in the digestive tract.

Magnesium Stearate

Improves manufacturing efficiency, ensures consistent tablet/capsule fill, generally recognized as safe.

Key Function

Lubricant, anti-adherent.

What it's used for

Pharmaceutical and supplement manufacturing aid to prevent ingredients from sticking

Key Benefits

Improves manufacturing efficiency, ensures consistent tablet/capsule fill, generally recognized as safe.

Science Behind It

Magnesium stearate is a salt formed from magnesium and stearic acid, a saturated fatty acid.

FAQ

What does magnesium do?

Magnesium is involved in over 300 enzymatic reactions in the body. EFSA-recognised contributions include normal muscle function, normal functioning of the nervous system, energy-yielding metabolism, the reduction of tiredness and fatigue, normal psychological function, electrolyte balance, and the maintenance of normal bones and teeth.

Why is a magnesium complex better than a single form?

Different magnesium forms are absorbed at different rates and tend to be associated with different effects — bisglycinate with sleep and stress, citrate with energy and digestion, malate with muscle recovery, taurate with cardiovascular support. A complex covers more bases in a single capsule.

When is the best time to take magnesium?

Most people take magnesium in the evening because of its association with relaxation and sleep. It can also be taken in the morning or with a meal — consistency over weeks matters more than timing.

What's the difference between magnesium bisglycinate and citrate?

Bisglycinate is bonded to the amino acid glycine, which makes it gentle on the stomach and well-absorbed; it's the form most associated with sleep and stress support. Citrate is bonded to citric acid, equally well-absorbed, and has a mild laxative effect at higher doses — which is why it's also used for occasional constipation.

How long does magnesium take to work?

Some people notice changes in sleep quality or muscle tension within a week or two; for fuller effects, allow four to eight weeks of consistent daily use to fully replenish depleted body stores.

Can magnesium help with sleep and stress?

Magnesium contributes to normal psychological function and normal functioning of the nervous system. Many people take magnesium specifically for its calming effect — particularly the bisglycinate form. We can't claim magnesium "treats" anxiety or insomnia, but it's one of the most popular supplements for sleep and stress support globally.

Can I take too much magnesium?

Excessive magnesium intake (typically over 400mg from supplements daily) can cause loose stools or digestive discomfort. The body excretes excess magnesium via the kidneys, so toxicity is rare in healthy adults — but those with kidney issues should consult their GP before supplementing.

Is thecary's Magnesium Complex vegan?

Yes. Our Magnesium Complex is fully vegan, GMO-free, and made in the UK in an FSSC 22000 certified facility. The capsule shell is plant-based.

Does magnesium interact with any medications?

Magnesium can interact with some antibiotics (tetracyclines, quinolones), bisphosphonates, and certain blood pressure or heart medications. If you take prescription medication, consult your GP or pharmacist before starting magnesium supplementation.

Can I take magnesium with other supplements?

Yes. Magnesium pairs especially well with our L-Theanine + Caffeine (balanced focus and recovery), Vitamin B Complex (broader nervous system support), and NMN 500mg (cellular energy).
