A natural, bioactive magnesium citrate derived from clean-label marine sources, optimized for tableting and granulation.

Calcium citrate stands apart from more common calcium sources like calcium carbonate in one key respect: it doesn't require stomach acid for absorption. Carbonate-based calcium relies on adequate gastric acid to be broken down and absorbed effectively, which makes it a poor fit for older adults, people using acid-reducing medications, or anyone with reduced stomach acid production — all common realities for a meaningful share of any calcium supplement's target market. This acid-independent absorption profile makes calcium citrate a more broadly reliable choice across diverse consumer groups, and it's also generally better tolerated on an empty stomach and less prone to causing the gas or bloating sometimes associated with carbonate forms. The trade-off is a lower elemental calcium content per gram compared to carbonate, so finished products typically require a larger fill weight to reach equivalent dosing — a practical formulation consideration worth factoring in early. Formulators can draw on the established list of EU-authorized health claims for calcium under Regulation (EU) 432/2012, including its contribution to normal function of digestive enzymes, normal muscle function, normal neurotransmission, maintenance of normal bones and teeth, and a role in the process of cell division — provided the finished product meets the required minimum content per the claim conditions. We provide complete traceability and full documentation — Certificate of Analysis, elemental calcium content confirmation, and independent third-party lab testing on request — with every batch.

Zinc bisglycinate is a chelated form of zinc, in which the mineral is bound to two glycine molecules — a structure that improves gastrointestinal tolerance and absorption compared to inorganic zinc salts such as zinc oxide or zinc sulfate, which are more prone to causing metallic aftertaste and digestive discomfort at effective dosages. This makes it a preferred choice for formulators building well-tolerated, daily-use mineral products, particularly where zinc is combined with other actives in a multi-ingredient formulation and gastrointestinal comfort is a priority for repeat purchase and compliance. Its chelated structure also offers good stability across a range of formulation matrices, from standard capsules and tablets to more sensitive gummy and chewable formats. Formulators can draw on the established list of EU-authorized health claims for zinc under Regulation (EU) 432/2012, including its contribution to normal function of the immune system, protection of cells from oxidative stress, normal cognitive function, maintenance of normal skin, hair and nails, and normal fertility and reproduction — provided the finished product meets the required minimum content per the claim conditions. We provide complete traceability and full documentation — Certificate of Analysis, elemental zinc content confirmation, and independent third-party lab testing on request — with every batch.

Magnesium citrate combines magnesium with citric acid to form a highly soluble, easily absorbed magnesium compound — a meaningful advantage over less bioavailable inorganic forms like magnesium oxide, which are cheaper but poorly utilized by the body. Its excellent water solubility also makes it a natural fit for powder-format and effervescent/drink-mix applications, not just capsules and tablets, offering flexibility across delivery formats. At typical elemental magnesium content of around 16%, molecular weight should be accounted for when calculating fill sizes and target dosing — citrate offers meaningfully better solubility and tolerability than carbonate-based forms, but at a lower elemental yield per gram than more concentrated forms such as bisglycinate, a trade-off worth factoring into cost and format planning. Buyers can draw on the extensive list of EU-authorized health claims for magnesium under Regulation (EU) 432/2012 — ten authorized claims in total, including its contribution to normal energy-yielding metabolism, electrolyte balance, normal muscle and nervous system function, reduction of tiredness and fatigue, and maintenance of normal bones and teeth — provided the finished product meets the required minimum content per the claim conditions. We provide complete traceability and full documentation — Certificate of Analysis, elemental magnesium content confirmation, and independent third-party lab testing on request — with every batch.
