Healthspan’s UK website sells four magnesium supplements to swallow. Magnesium Glycinate gives 100mg of magnesium per tablet, taken two or three a day. Magnesium 375mg and Elite Magnesium Plus give 375mg in one tablet, mainly as oxide, with B vitamins. Opti-Magnesium gives 375mg from two tablets of glycinate, citrate and malate.
Facts below come from Healthspan’s own website and labels, checked on 26 October 2026. Evopure isn’t connected with Healthspan, and we don’t rate or review other brands.
Healthspan’s magnesium range
| Product | Magnesium form | Magnesium a day | Daily dose |
|---|---|---|---|
| Magnesium Glycinate | Bisglycinate, oxide | 200 to 300mg | 2 to 3 tablets |
| Magnesium 375mg | Oxide, hydroxide | 375mg | 1 tablet |
| Elite Magnesium Plus | Oxide | 375mg | 1 tablet |
| Opti-Magnesium | Glycinate, citrate, malate | 375mg | 2 tablets |
The category also lists Heart Synergex (a daily pack including 75mg of magnesium) and a Magnesium and Glucosamine Gel with 7.5% magnesium chloride, for external use only. See our magnesium spray guide on skin absorption, and the types of magnesium for each form.
Healthspan Magnesium Glycinate: the label maths
Each tablet contains 500mg of magnesium glycinate, providing 100mg of elemental magnesium (27% of the nutrient reference value, or NRV). Only the elemental figure counts towards your daily amount:
- 2 tablets: 1,000mg of glycinate, 200mg of magnesium.
- 3 tablets: 1,500mg of glycinate, 300mg of magnesium. This is the “1500mg” people search for.
The ingredients list a “buffered” magnesium glycinate, made of magnesium bisglycinate plus magnesium oxide; the label doesn’t say how much comes from each. Other ingredients include microcrystalline cellulose, dicalcium phosphate and talc. Take two to three tablets with water, one hour before bedtime. Packs of 120, marked suitable for vegans. For the research on this form, see our magnesium glycinate guide.
Magnesium 375mg vs Elite Magnesium Plus
Both give 375mg of magnesium per tablet (100% NRV), plus vitamin C and B vitamins including 0.7mg of vitamin B6, and both are marked vegan. The differences:
- Magnesium 375mg: magnesium oxide and hydroxide. One tablet with water at night-time before bed. Packs of 90.
- Elite Magnesium Plus: the ingredients list magnesium oxide. One tablet a day. Packs of 120. Healthspan says LGC’s sports anti-doping laboratory tests it for substances banned by WADA. See magnesium for active people.
Oxide packs a lot of magnesium into a small tablet. In a small US study only about 4% of oxide was absorbed, though a higher dose can still supply a useful amount.
Opti-Magnesium: three forms in one
Opti-Magnesium was recently reformulated as a “triple-source” blend of glycinate (listed as 20% of the blend), citrate and malate, with some oxide. Each tablet gives 187.5mg of magnesium, so two give 375mg, plus 5µg of vitamin D3, 1.4mg of B6 and 200mg of inulin. It is marked suitable for vegetarians rather than vegans. In a 60-day UK trial in 46 adults, citrate raised blood magnesium more than oxide. More in our guides to citrate, malate and magnesium blends.
Where Evopure fits
Evopure isn’t connected with Healthspan. Our products are different, not like-for-like swaps:
- Magnesium Glycinate Sleep Complex: a berry 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 and to normal psychological function.
- Reishi Mushroom Adaptogenic Complex: a reishi hot chocolate with organic cacao and maca. It contains a little natural caffeine.
- Sleep CBD Oil: broad spectrum CBD with 0% THC, plus passion flower, for an evening routine. CBD isn’t a treatment for sleep problems.
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.
Healthspan magnesium for sleep
Healthspan says its glycinate is made for an evening routine. 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. See magnesium for sleep and the best time to take magnesium.
375mg, the NRV and adding it up
The 375mg on several Healthspan labels is the NRV, a labelling reference. The NHS says adults need 300mg (men) or 270mg (women) a day, and that 400mg or less a day from supplements is unlikely to cause harm. More than 400mg for a short time can cause diarrhoea. Three Magnesium Glycinate tablets plus one Magnesium 375mg tablet would add 675mg, so add up every product you take.
Healthspan’s labels say to check with a doctor or pharmacist first if you take prescribed medication or have a medical condition; the glycinate label adds pregnancy and breastfeeding. See how much magnesium per day and magnesium side effects. For a general guide, see our UK magnesium supplement guide, or compare Solgar and Holland and Barrett.
