GLOV Magnesium Complex: What’s in It, How Much Magnesium and UK Delivery

What’s in GLOV Magnesium Complex?

The full name on GLOV’s site is Magnesium Complex, Longevity and Cortisol Support. Here is what its own pages say:

The two pages don’t list the same forms, and neither shows how much magnesium comes from each one. If you buy it, check the supplement facts on your pouch. For what each form is, see our guide to the types of magnesium.

The label maths: is 300mg a lot?

GLOV gives the elemental figure, the magnesium itself rather than the weight of the compounds, which makes it easy to compare. Our sums:

• Per capsule: 300mg from two capsules is 150mg each.
• Against UK needs: the NHS says adults need 300mg (men) or 270mg (women) a day, mostly from food. 300mg is 80% of the 375mg nutrient reference value used on UK labels.
• Against the upper level: the NHS says 400mg or less a day from supplements is unlikely to cause harm. One serving of GLOV plus a multivitamin or a second magnesium product could pass that, so add them up.
• Per pouch: 60 capsules at two a day is 30 servings.

For comparison, Solgar Magnesium Glycinate gives 240mg from two capsules, and labels on the 12 in 1 magnesium complexes we checked range from 400mg to 500mg. Some brands quote compound weight instead, as we found at Holland and Barrett. Use how much magnesium per day as your yardstick.

Where Evopure fits

Evopure isn’t connected with GLOV. If you’d rather buy magnesium made in the UK, ours is a different approach, not a like-for-like swap:

• 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 and to normal psychological function.
• Reishi Mushroom Adaptogenic Complex: a reishi hot chocolate with cocoa and maca. It contains a little natural caffeine.
• Sleep CBD Oil: broad spectrum CBD with 0% THC, plus passion flower, for an evening routine.

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, made in the UK and for adults (18+) only. To compare other options, see our UK magnesium supplement guide.

Cortisol and the eight forms: what UK rules say

GLOV markets the complex for sleep, stress and cortisol. In Great Britain, the authorised health claims belong to magnesium as a nutrient, whatever the form: it contributes to a reduction of tiredness and fatigue, to normal muscle function, to normal functioning of the nervous system and to normal psychological function. There is no authorised claim about cortisol, belly fat or longevity.

Of the eight forms on the product page, orotate isn’t on the GB list of mineral forms permitted in food supplements; see magnesium orotate. Oxide is permitted but is one of the less well absorbed forms; see magnesium oxide.

On stress, the research on magnesium is limited. A 2017 systematic review of 18 studies called the evidence suggestive but of poor quality, and we found no published trial of GLOV’s own formula. More in magnesium and anxiety and cortisol belly.

Buying GLOV in the UK

• Where: GLOV’s own website, which shows prices in pounds. GLOV-branded magnesium didn’t come up when we searched Amazon UK on 31 October 2026.
• Delivery: orders ship from GLOV’s US warehouse, with 5 to 8 business days quoted for the UK.
• Customs: GLOV’s shipping policy says international orders may be charged duties, taxes or customs fees, paid by the customer.
• Guarantee: GLOV’s site offers a 60-day money-back guarantee on supplements.

Who should check first

The NHS says taking more than 400mg of magnesium for a short time can cause diarrhoea. Ask your GP or pharmacist before taking any magnesium if you have kidney disease, or take antibiotics, alendronic acid, levothyroxine or other regular medicines. More in magnesium side effects and the best time to take magnesium.

We don’t recommend our products during pregnancy or breastfeeding. Our products are for adults (18+) only.

A UK capsule with the same three forms is Nutrition Geeks Magnesium Glycinate 3-in-1, at 384mg per two capsules.

Comparing complexes? Bettervits Magnesium Complex gives 225mg of magnesium in two capsules, with zinc and D3.
