What This Product Provides, and a Naming Correction
Each 4-capsule serving delivers 307mg of elemental magnesium from 2560mg of magnesium bisglycinate — magnesium chelated with two glycine molecules, generally well absorbed and gentle on digestion compared to less bioavailable forms like magnesium oxide. As covered in more detail in our complete magnesium guide, it’s worth correcting a common marketing distinction: “magnesium bisglycinate” and “magnesium glycinate” are chemically the same compound — bisglycinate is simply the more technically precise chemical name (two glycine molecules per magnesium ion), while glycinate is the shorter, more common label term. They aren’t two different products with different absorption profiles, despite sometimes being compared as if they were.
Magnesium is involved in over 300 biochemical reactions, with established roles in normal muscle function, nervous system function, energy metabolism, and bone maintenance. This product’s 307mg elemental magnesium dose sits within the UK’s 400mg daily upper safe level for supplemental magnesium, which is worth knowing if you’re also taking other magnesium-containing products.
Two safety points worth adding: if you have kidney disease, check with your GP before starting, since impaired kidneys are less able to clear excess magnesium. If you take bisphosphonate medication (commonly prescribed for osteoporosis), magnesium can significantly reduce its absorption — space doses several hours apart, ideally as advised by your GP or pharmacist.
For children, magnesium needs and appropriate doses differ meaningfully from adults, so this should be guided directly by a GP or paediatric healthcare professional rather than an adult product used at an adjusted amount.
This formula includes alfalfa and a pullulan (tapioca-derived) capsule shell, manufactured in GMP-certified facilities. Take 4 capsules daily with water, preferably with a meal, or as directed by your healthcare practitioner. Speak to your GP before starting if you have kidney disease, take bisphosphonate medication, are pregnant or breastfeeding, or have an existing health condition.
