BioCare sells magnesium in four single forms: Magnesium Glycinate (200mg of magnesium from two capsules), Magnesium Citrate (300mg from three), Magnesium Malate (117mg from three) and Magnesium Taurate (146mg from two). It also sells a powder and three magnesium complexes. All are listed as vegan when we checked in October 2026.
BioCare is a UK supplement company founded more than 35 years ago by John Stirling, and it offers free advice from its own nutrition team. Facts below come from BioCare’s website, checked on 26 October 2026. Evopure isn’t connected with BioCare, and we don’t rate or review other brands.
BioCare’s magnesium range
These are the magnesium-led products on BioCare’s magnesium page. The figure is elemental magnesium (the magnesium itself) for the full daily dose on the label:
| Product | Magnesium form | Magnesium a day | Daily dose |
|---|---|---|---|
| Magnesium Glycinate | Bisglycinate | 200mg | 2 capsules |
| Magnesium Citrate | Citrate | 300mg | 3 capsules |
| Magnesium Malate | Malate | 117mg | 3 capsules |
| Magnesium Taurate | Taurate | 146mg | 2 capsules |
| Magnesium Powder | Malate and citrate | 200mg | Half a teaspoon |
| Magnesium Phospholipid Complex | Citrate and bisglycinate | 300mg | 3 capsules |
| Magnesium Calcium Complex | Citrate | 200mg | 3 capsules |
| Calm Complex | Bisglycinate and citrate | 100mg | 2 capsules |
| Sleep NutriPowder | Bisglycinate | 100mg | 1 teaspoon |
Most capsule labels say one capsule two or three times a day with food; Calm Complex is two capsules daily. Every product above is listed as suitable for vegans, and the capsule shells are plant cellulose (HPMC).
Glycinate, citrate, malate or taurate: what is the difference?
Each form is magnesium bound to a different partner, which changes how much magnesium you get per capsule. For the bigger picture, see the types of magnesium.
- Glycinate: magnesium bound to the amino acid glycine. BioCare’s ingredient list says magnesium bisglycinate, which is the same thing, so “BioCare magnesium bisglycinate” and “BioCare magnesium glycinate” are one product. Two capsules give 200mg of magnesium (100mg each) plus 1,400mg of glycine. More in our magnesium glycinate guide.
- Citrate: magnesium bound to citric acid, 100mg per capsule, the highest single-form strength in the range. See magnesium citrate.
- Malate: magnesium bound to malic acid, a fruit acid. Three capsules give 117mg of magnesium and 720mg of malic acid. See magnesium malate.
- Taurate: magnesium bound to the amino acid taurine. Two capsules hold 1,574mg of magnesium taurate but only 146mg of magnesium. See magnesium taurate.
That taurate figure is the label maths to watch: the compound weight is much bigger than the magnesium in it. Some brands name products by compound weight, as we found at Holland and Barrett. BioCare names its products by form and gives the elemental figure.
On absorption, the evidence is small. In a 60-day UK trial in 46 healthy adults taking 300mg a day, citrate and an amino-acid chelate were absorbed better than magnesium oxide, and citrate raised blood magnesium the most.
Where Evopure fits
Evopure isn’t connected with BioCare. Our products are different, not like-for-like swaps:
- Magnesium Glycinate Sleep Complex: a berry-flavoured drink powder with magnesium bisglycinate and citrate (148mg of magnesium per serving), glycine, L-theanine, chamomile, passionflower, hops and oat straw. Magnesium contributes to a reduction of tiredness and fatigue.
- Sleep CBD Oil: broad spectrum CBD with 0% THC, plus passion flower and a night-time terpene blend, for an evening routine. CBD isn’t a treatment for sleep problems.
- Reishi Mushroom Adaptogenic Complex: a reishi hot chocolate with organic cacao and maca. It contains a little natural caffeine.
The FSA’s 10mg a day figure is precautionary advice rather than a legal limit, set while longer-term safety research continues. At Evopure we think it is a very cautious figure, and many adults use more. If you go above it, increase slowly, and check with your GP or pharmacist first if you take any medication.
All three are vegan and made in the UK, for adults (18+) only. We don’t recommend our products during pregnancy or breastfeeding.
Magnesium complex, powder and calcium complex
BioCare doesn’t sell a product called just “Magnesium Complex”. People searching for it usually mean one of these:
- Magnesium Phospholipid Complex: 300mg of magnesium from citrate and bisglycinate, with 99mg of soya-free sunflower lecithin providing 60mg of phosphatidylserine, from three capsules.
- Magnesium Calcium Complex: 200mg of magnesium and 150mg of calcium, both as citrate, from three capsules. See magnesium and calcium and magnesium for bone health.
- Magnesium Powder: magnesium citrate and malate only, 200mg in half a teaspoon (about 1.5g) mixed into water or juice. A 90g tub is 60 days at that dose. Compare formats in powder vs tablets.
For how blends compare with single forms, see magnesium complex.
BioCare magnesium for sleep
BioCare has two sleep-themed products with magnesium. Calm Complex adds lemon balm, holy basil, L-theanine and taurine to 100mg of magnesium. Sleep NutriPowder adds lemon balm, hops, L-theanine, taurine and two cherry powders to 100mg of magnesium as bisglycinate, taken an hour before bed.
No sleep claim for magnesium is authorised in the UK, and the research is modest. A 2021 review of three trials in 151 older adults found people fell asleep about 17 minutes faster than with placebo, but rated the evidence low to very low quality. A 2025 trial in 155 adults with poor sleep, using 250mg of magnesium as bisglycinate, found a small improvement at four weeks. More in magnesium for sleep, glycine for sleep and lemon balm.
How much a day, and who should check first
The NHS says adults need 300mg (men) or 270mg (women) of magnesium a day, and that 400mg or less a day from supplements is unlikely to cause harm. Citrate or Phospholipid Complex at the full dose gives 300mg, so add up every product you take, including multivitamins. See how much magnesium per day and magnesium side effects.
Calm Complex and Sleep NutriPowder both say they are not suitable during planned pregnancy, pregnancy or breastfeeding, and to take care with sleep, antidepressant and mood medication. Sleep NutriPowder also says it is not for under-18s, not to take it on an empty stomach, and not on the same day as other green tea products.
BioCare doesn’t sell a magnesium-only product for children. Its Children’s Complete Multinutrient and Children’s Mindlinx Multinutrient powders include magnesium among many nutrients, with doses by age. Ask a GP or pharmacist before giving any supplement to a child, and see magnesium for kids. Our general guide to choosing a magnesium supplement in the UK covers other brands too.
