Magnesium

Magnesium is one of the most abundant minerals in the human body and plays a structural and catalytic role across hundreds of metabolic pathways. Dietary intake in modern Western populations frequently falls short of recommended levels — particularly among adults under stress, endurance athletes, and people on restricted diets — which has made magnesium one of the most-requested actives in private-label gummy ranges over the last five years.

For private-label brands, the practical formulation challenge is delivering meaningful doses (100–200 mg elemental magnesium per serving) within the bulk constraints of a 2.5 g gummy. Most commercial gummies position at 25–50% NRV per piece and direct consumers to a multi-piece daily serving. Sachets — which DAT also manufactures — deliver full NRV more readily and are the format of choice for ranges marketing 'full daily magnesium' in a single serving.

Origin and history

Magnesium was first isolated as a pure element by Sir Humphry Davy in 1808 through electrolysis of magnesium oxide. Its essentiality for human nutrition was established through deficiency studies in the mid-20th century, and dietary reference values for magnesium have been in place across EU and US regulatory frameworks since the 1970s.

Commercially supplied magnesium for supplements is produced as one of several salts: chelated forms such as bisglycinate (magnesium bound to two glycine molecules), organic salts such as citrate, malate, or L-threonate, and inorganic salts such as oxide. Marine magnesium — extracted from sea-water — has gained share in beauty-and-wellness positioning despite delivering a similar profile to other organic forms. Each form differs in elemental-magnesium yield per gram, taste profile, and bioavailability.

Scientific overview

Magnesium acts as a cofactor for more than 300 enzymes including those involved in ATP synthesis, DNA and protein synthesis, glucose metabolism, and neurotransmitter regulation. It is essential for normal nerve transmission, muscle contraction (and relaxation), maintenance of normal heart rhythm, and bone mineralisation.

Bioavailability varies significantly by salt form. Bisglycinate and citrate are typically absorbed at 30–40% of ingested dose; oxide is absorbed at 4–10%, though oxide carries a higher elemental-magnesium payload per milligram, partially offsetting the absorption gap. L-threonate is positioned for cognitive applications based on animal research suggesting differential CNS uptake, though large-scale human trials remain limited. Magnesium absorption is regulated by intestinal transporters and influenced by intake of calcium, phosphate, and phytates from food.

For gummy manufacturing, the choice of salt is primarily driven by palatability, bulk, and target consumer. Bisglycinate is the standard recommendation: best mouth-feel, well-tolerated, and well-suited to sleep & calm or recovery-positioned SKUs. Citrate is a cost-effective alternative with slight acidity that pairs well in citrus flavour systems. Oxide is rarely chosen on its own for gummy SKUs due to the mineral taste profile, but can be blended in cost-sensitive formulations when masked.

Magnesium has been one of the most familiar and commercially understood gummy actives across EU and US markets over the past five years. Sleep & calm ranges are the dominant use case — typically pairing magnesium bisglycinate with L-theanine, lemon balm, or low-dose melatonin (where regulation permits). Muscle and recovery ranges combine it with vitamin B6, vitamin D3, and electrolytes. Women's- wellness ranges pair it with vitamin B6 and folate for menstrual- comfort positioning. Senior ranges use it for energy/fatigue and bone positioning.

From a formulation standpoint, magnesium is one of the more demanding actives to fit into a gummy at meaningful doses. Elemental magnesium yields differ markedly across salts (oxide ~60%, citrate ~16%, bisglycinate ~14%), so a 100 mg elemental dose translates to roughly 166 mg oxide, 625 mg citrate, or 714 mg bisglycinate — meaningful contributors to gummy mass. Pectin-base gummies typically accommodate 100–150 mg elemental magnesium per 2.5 g gummy without compromising texture; higher doses require larger gummy size or a multi-piece serving.

For pack-copy, the most common EU briefs are 'sleep & calm', 'muscle function', and 'tiredness & fatigue' — all of which have authorised claim wording under Regulation 432/2012. Brand owners should avoid 'helps you sleep' in consumer-facing copy unless reviewed case-by- case. DAT reviews final pack copy per project against the authorised list before production.
