🔬 What is Magnesium Bisglycinate? Understanding the form matters

Bisglycinate means magnesium is bonded (chelated) to two molecules of the amino acid glycine. This protective bond survives stomach acid, reaching the intestine intact for superior absorption versus oxide or citrate forms.

Magnesium oxide — the most common and cheapest form — has around 4% absorption. Bisglycinate consistently shows 40–60% absorption in comparative studies, meaning you need far less to achieve the same effect.

The glycine chelation prevents the osmotic laxative effect that causes digestive upset with high-dose oxide or citrate, making bisglycinate the preferred form for daily use.

🕐 When to Take It Timing optimises your results

Taking 1 capsule 1–2 hours before bed is supported by the evidence on sleep quality. Magnesium's calming effect on NMDA receptors helps ease the transition into deeper sleep stages.

The second capsule with your first meal takes advantage of food-enhanced absorption. Fat-soluble vitamin D3 in the formula also absorbs best alongside dietary fats.

If training hard, timing one capsule within 90 minutes of finishing exercise can support muscle recovery, as magnesium is rapidly lost through sweat and urinary excretion during intense activity.

Research shows the most significant benefits come from consistent daily supplementation over 4–12 weeks. Missing one dose occasionally matters far less than stopping entirely.

👥 Who Benefits Most? Populations most likely to be deficient

Exercise dramatically increases magnesium requirements. Heavy trainers, endurance athletes, and people in physical jobs are at high risk of depletion through sweat loss.

Cortisol (the stress hormone) directly increases urinary magnesium excretion. People managing high-stress work or life demands cycle through magnesium significantly faster.

Low magnesium status and poor sleep reinforce each other in a feedback loop. Bisglycinate breaks that cycle with glycine's additional calming neurotransmitter effects.

Magnesium is highest in dark leafy greens, nuts, seeds, and whole grains. Western diets processed of these foods leave a significant gap that supplementation helps fill.

🧩 Nutrient Interactions What pairs well and what to watch

Magnesium is required to convert vitamin D into its active form. Without adequate magnesium, supplemental D3 may remain inactive. Our formula pairs them deliberately.

B6 (as P-5-P) facilitates magnesium transport into cells. Research shows B6 co-supplementation increases intracellular magnesium levels more than magnesium alone.

Calcium and magnesium compete for the same intestinal transporters. If you also take calcium supplements, separate them by at least 2 hours to avoid absorption interference.

Always consult your GP or pharmacist if you take diuretics, antibiotics, or medications for heart conditions before starting supplementation. Food supplements are not a substitute for medical treatment.
