Together Health Magnesium is a vegan capsule made from purified seawater extract. It contains five natural forms of magnesium (oxide, hydroxide, sulfate, carbonate and chloride) plus 18 trace minerals, and one capsule gives 198mg of magnesium, 53% of the reference intake. It isn’t magnesium glycinate. Its Night Time capsules add 5-HTP and hops.
Facts below come from Together Health’s own UK website, checked on 26 October 2026. Evopure isn’t connected with Together Health, and we don’t rate or review other brands.
Together Health’s magnesium products
| Product | What’s in it | Magnesium a day | Daily dose |
|---|---|---|---|
| Magnesium | Seawater magnesium, 18 trace minerals | 198mg | 1 capsule |
| Night Time | Seawater magnesium, 5-HTP 100mg, hops 100mg | 188mg | 2 capsules |
| Stress Aid | B vitamins, ashwagandha, rhodiola, schisandra | 55mg | 1 capsule |
The Magnesium label says to take one capsule a day and not more than two, with or without food, at any time of day. The cellulose capsules can be opened and mixed into food or drink. Its web address still reads “marine-magnesium”, and some shops list it as Marine Magnesium. Together Health’s bundles (Calm Complete, Bone Complete and Energy Complete) include the same Magnesium capsule.
What “5 natural forms” means on the label
Most supplements use one magnesium compound, such as glycinate, citrate or oxide. Together Health instead evaporates and purifies seawater, which leaves a natural mix of five mineral salts. The page doesn’t say how much of the 198mg comes from each form.
The 198mg is elemental magnesium, the figure that counts against your daily intake, so there’s no compound-weight maths to do. The ingredients are seawater extract, a coconut and tapioca extract blend used as a flow agent, and a cellulose capsule. The page says it is vegan certified, made in the UK and tested for heavy metals.
How it compares by form
- Seawater blend (Together Health): several inorganic salts in one capsule.
- Glycinate (bisglycinate): magnesium bound to the amino acid glycine. Together Health doesn’t sell a glycinate.
- Citrate: magnesium bound to citric acid, common in powders and tablets.
- Oxide: a lot of magnesium per gram, but often found less well absorbed.
The absorption research 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 oxide, and oxide made no difference compared with placebo. We found no trial of Together Health’s seawater blend itself. For every form side by side, see the types of magnesium and glycinate vs citrate vs threonate.
Where Evopure fits
Evopure isn’t connected with Together Health. 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.
- 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. 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.
Is Together Health magnesium good for sleep?
No sleep claim for magnesium is authorised in the UK, and Together Health’s labels don’t make one. A 2021 review of three small trials in older adults found people fell asleep about 17 minutes faster than with placebo, but rated the evidence low quality. See magnesium for sleep and the best time to take magnesium.
Night Time is taken as two capsules 30 minutes before bed. Because it contains 5-HTP, its label says not to take it with antidepressants, including MAOIs, to speak to your doctor if you take other medicines, and to stop at least two weeks before surgery.
Taking magnesium together with vitamin D, zinc or ashwagandha
Many searches are about combining magnesium with other supplements. There’s no general rule against it, but add up the magnesium from every product, as multivitamins often contain some. Our guides cover magnesium and vitamin D, magnesium and zinc, ashwagandha and magnesium and magnesium and calcium.
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. More than 400mg for a short time can cause diarrhoea. Two Magnesium capsules give 396mg, so taking Night Time as well would go over 400mg. Together Health’s page says to consult a doctor first if you take medication or have a medical condition. See how much magnesium per day and magnesium side effects.
