Magnesium Bisglycinate Gummies UK: How Much Magnesium Do You Really Get?

How much magnesium is in magnesium bisglycinate gummies?

Most magnesium bisglycinate gummies sold in the UK give between about 30mg and 75mg of magnesium per gummy, and 60mg to 150mg per daily serving of two. That is roughly 17% to 39% of the 375mg NRV on UK labels, and well under the 270mg (women) or 300mg (men) the NHS says adults need each day.

Most people get much of that from food such as wholegrains, nuts, seeds and beans: see foods high in magnesium and how much magnesium you need per day.

SP Nutrition magnesium bisglycinate gummies

SP Nutrition (SPNutrition) magnesium bisglycinate gummies are sugar-free gummies sweetened with stevia, made with pectin and described as vegan, sold from the brand’s US website with prices in pounds. A serving is two gummies, 30 servings a bag, and the product page lists 400mg of magnesium bisglycinate per serving (checked 13 November 2026).

Magnesium is only about 11 to 14% of magnesium bisglycinate by weight, so 400mg of bisglycinate would give roughly 45mg to 56mg of magnesium (our sums), and the page doesn’t say how much of the 400mg is elemental magnesium. Ask the brand if you want that figure. Its directions are two gummies an hour or two before bed. We go through the full label in SP Nutrition magnesium gummies explained. Evopure isn’t connected with SPNutrition.

Figures from each brand’s own product page, checked 12 November 2026 (facts only, no prices). Each daily serving is two gummies.

None of these pages gives grams of sugar per serving, so check the pack. SPNutrition sells from a US website: we work through its label in SPNutrition magnesium bisglycinate gummies explained.

Why do gummies hold so little magnesium?

Gummies hold little magnesium because magnesium is a bulky mineral. In magnesium bisglycinate, each magnesium atom is bound to two glycine molecules, so most of the weight is glycine. Pure magnesium bisglycinate is about 14% magnesium, and supplement-grade ingredients often less, so a useful dose takes grams of powder that a small gummy can’t carry.

The labels show it. Holland and Barrett’s high strength gummies use 1,440mg of magnesium bisglycinate in two gummies to give 140mg of magnesium, so each gummy already carries 720mg of the compound for 70mg of magnesium. To reach 300mg of magnesium from bisglycinate alone you would need roughly 2 to 3g of the compound, before any gelling agent, sweetener or flavour, which means several gummies a day.

So some gummies add magnesium citrate (more magnesium per gram) or stay at a modest dose; a scoop of powder can hold far more. Our glycinate vs bisglycinate guide explains the naming, and magnesium glycinate explained covers the form itself.

How to read a magnesium gummy label

Four checks tell you what you’re really getting:

• Elemental magnesium, not the compound. “1,440mg magnesium bisglycinate” and “140mg magnesium” can describe the same serving. The magnesium line with a %NRV is the number that counts.
• Per serving or per gummy. Most labels quote two gummies. Halve it for one.
• Pure or a blend. “Glycinate” on the front can sit alongside citrate or oxide in the ingredients, which can loosen stools more. See our chart of magnesium types.
• What else is in it. Herbs such as ashwagandha, extra vitamins or iodine add their own cautions, and B6 or iodine can add up if you take other supplements.

Sugar and sweeteners in magnesium gummies

Magnesium gummies are either sugared, usually with sugar and glucose syrup, or sugar free, sweetened with polyols such as maltitol, isomalt and erythritol. The NHS advises adults to have no more than 30g of free sugars a day, and sugary gummies count towards it, especially if you take several kinds.

Sugar-free isn’t automatically gentler. UK labelling law requires an “excessive consumption may produce laxative effects” warning on foods with more than 10% added polyols, and magnesium itself can loosen stools. If gummies upset your stomach, try one with food, or switch format. More in gummy vitamins vs pills.

Are magnesium bisglycinate gummies worth it?

Magnesium bisglycinate gummies are worth it if you dislike tablets and only want a small top-up, around 100mg to 150mg a day. They are a poor fit if you want a larger amount, as reaching even 300mg means several gummies and more sugar or sweetener. Compare the magnesium per serving across formats before you buy.

Are magnesium gummies good for sleep?

Many magnesium gummies are sold as bedtime products, but in Great Britain magnesium has no authorised health claim about sleep. Its authorised claims include contributing to a reduction of tiredness and fatigue, normal functioning of the nervous system, normal psychological function and normal muscle function.

Who should check first

The NHS says taking 400mg or less of magnesium a day from supplements is unlikely to cause any harm. EFSA sets a lower upper level of 250mg a day for magnesium from supplements, mainly to avoid diarrhoea. Add up every product you take, including multivitamins.

• Kidney disease: speak to your GP before any magnesium supplement.
• Medicines: magnesium can reduce the absorption of some antibiotics, levothyroxine and bisphosphonates. Ask a pharmacist how far apart to take them.
• Children: adult gummies look like sweets, so keep them out of reach. Read are magnesium gummies safe for kids?
• Pregnancy and breastfeeding: ask your midwife or GP first. See magnesium in pregnancy.
• Gummies with ashwagandha: not for pregnancy or breastfeeding, and check first with thyroid conditions, liver problems or regular medicines. See the UK ashwagandha safety review.

Loose stools are the usual sign of too much. Our magnesium glycinate side effects guide covers what’s normal and when to get help.

Where Evopure fits

Evopure doesn’t sell magnesium gummies. Our Magnesium Glycinate Sleep Complex is a berry-flavoured drink powder: one 4.75g scoop in water gives 290mg of magnesium (77% NRV) from 1,000mg magnesium bisglycinate and 900mg magnesium citrate, plus 500mg glycine, 100mg L-theanine, oat straw, hops, chamomile and passionflower, which are listed as ingredients only. It is sweetened with stevia, vegan and made in the UK.

One scoop gives about twice the magnesium of the strongest gummies above, without sugar. Because it contains citrate, start with a smaller scoop if your stomach is sensitive. Magnesium contributes to a reduction of tiredness and fatigue and to normal psychological function. Read more on the benefits of magnesium.

The Reishi Mushroom Adaptogenic Complex is a reishi hot chocolate with 0.5g reishi, 0.5g maca and 0.3g cinnamon per 8g, and contains a little natural caffeine from the cocoa. Its pack says it is not for pregnant or nursing women or people on medication. The Broad Spectrum CBD Capsules give one 10mg capsule of CBD, so there is nothing to measure. They are for adults only. If you take any regular medicines, check with a GP or pharmacist first.

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.
