Magnesium Glycinate - SuperDosed™


Most magnesium supplements rely on cheap, poorly absorbed salts like magnesium oxide or blends bulked with fillers.

SuperDosed™ is different: 2 capsules daily deliver 300 mg pure elemental magnesium as glycinate — the form known for superior absorption and gentleness on the stomach.

No fillers, no blends, no compromise — just UK-made magnesium, tested for purity and potency, and formulated to work with your body, not against it.

Magnesium is an essential mineral involved in over 300 enzyme reactions. Magnesium glycinate is one of the most bioavailable and well-tolerated forms, chosen for:

  • Energy & fatigue — contributes to normal energy-yielding metabolism and reduction of tiredness.
  • Muscle function — supports normal muscle contraction and relaxation, helping reduce cramping.
  • Nervous system & mood — contributes to normal nervous system function and psychological balance.
  • Bone health — helps maintain normal bones and teeth by supporting calcium balance.

Take 2 capsules once daily, providing 300 mg elemental magnesium (from 2,100 mg magnesium glycinate). Swallow with water, ideally with your evening meal, as many people find magnesium most helpful for relaxation and sleep when taken later in the day.

You can take it at any time of day, with or without food. Consistent daily use is recommended to maintain energy, muscle, and nervous system health.


Ingredients: Magnesium glycinate (providing 300 mg elemental magnesium per 2 capsules), Naturally occuring sulphur derived from plants and found naturally in fruits and vegetable (MSM), vegetarian capsule (HPMC).

Free from: fillers, binders, stabilisers, GMOs, and common allergens.


Clinical studies and nutritional guidelines highlight the importance of adequate magnesium intake:

  • Daily requirements: The UK Nutrient Reference Value (NRV) is 375 mg/day for adults. Surveys show many people fall short, especially those with high stress, poor diet, or intense exercise (Elin, 2010, Am J Clin Nutr).
  • Sleep & stress: Trials with 250–500 mg/day of magnesium (often glycinate or citrate) show improvements in sleep quality and stress resilience (Abbasi et al., 2012, J Res Med Sci; Boyle et al., 2017, Nutrients).
  • Muscle function & recovery: Doses of 300–400 mg/day have been shown to reduce cramping and support performance recovery (Zhang et al., 2017, Medicine).
  • Mood & anxiety: Clinical data suggest 300–400 mg/day may support psychological health, particularly in stressed or magnesium-deficient individuals (Tarleton et al., 2017, PLoS One).

Our formula delivers 300 mg elemental magnesium daily, in the glycinate form for maximum absorption and digestive comfort — right in line with the clinically effective range.

Safety: Magnesium glycinate is gentle and well-tolerated. Very high intakes (above ~800 mg/day elemental magnesium) may cause loose stools, but at 300 mg/day this is unlikely.

Frequently Asked Questions


Most high-street brands underdose their products, the active ingredients are far below the levels used in real studies.
