Magnesium Glycinate: What to Look For in a UK Magnesium Supplement
Magnesium glycinate has quietly become one of the most searched-for supplements in the UK — but the form on the label matters far more than the word on the front of the pot. If you have found yourself comparing magnesium products and wondering why some say glycinate, others malate, and a few list three forms at once, this guide is for you.
Below, the activGen team explains what magnesium glycinate actually is, how the common forms differ, and what to look for when you are choosing a supplement — written in plain English.
What is magnesium glycinate?
Magnesium glycinate (sometimes called magnesium bisglycinate) is magnesium bound to glycine, an amino acid. Manufacturers often pair magnesium with an amino acid or organic acid — this is called a chelate — because the resulting compound tends to be gentle on the stomach and is a popular choice for people who find other forms less comfortable to take.
It is worth being clear about one thing from the outset: magnesium is magnesium. The mineral itself is the same regardless of what it is bound to. The form mainly affects how much elemental magnesium a capsule carries, how well it is tolerated, and how it tastes or feels to take. That is why the form is the first thing to look at.
Why is magnesium so talked about right now?
Magnesium is an essential mineral, which means the body cannot make it and we have to get it from food — leafy greens, nuts, seeds, wholegrains and pulses are all good sources. Interest has grown partly because surveys suggest a meaningful share of UK adults do not reach the recommended intake from diet alone.
Magnesium is one of the minerals with well-established roles in the body. Where a food or supplement provides a significant amount of it, magnesium contributes to normal muscle function, to normal functioning of the nervous system, to normal psychological function, to a reduction of tiredness and fatigue, and to the maintenance of normal bones and teeth. These are everyday support roles — not claims to treat, prevent or cure anything.
What about taking it in the evening?
You will often see magnesium discussed as part of an evening wind-down routine. People choose to take it at different times of day for personal convenience; there is nothing special you need to do. The sensible approach is simply to take it consistently, with or after food, and to follow the dosage on the label.
Which form of magnesium should you look for?
There is no single "best" form for everyone — it depends on what you want from it and how your stomach responds. Here is a quick comparison of the forms you are most likely to see on UK shelves.
| Form | What it is | Often chosen for |
|---|---|---|
| Magnesium glycinate | Magnesium bound to the amino acid glycine (a chelate) | Being gentle on the stomach; an everyday all-rounder |
| Magnesium malate | Magnesium bound to malic acid | People who prefer a form taken earlier in the day |
| Magnesium taurate | Magnesium bound to the amino acid taurine | Those who like an amino-acid chelate |
| Magnesium citrate | Magnesium bound to citric acid | Good absorption; higher doses can loosen the bowels |
| Magnesium oxide | An inexpensive inorganic salt | Budget products; lower elemental absorption |
What to look for on the label
- The form (or forms) of magnesium. Chelated forms such as glycinate and taurate are popular for everyday use. Some products, like our Magnesium Complex, combine three forms in one capsule.
- Elemental magnesium per serving. The figure that matters is the amount of actual magnesium, not the weight of the whole compound. Check the supplement information panel.
- Supporting nutrients. Some complexes add nutrients with their own roles — for example, vitamin B6, which also contributes to normal psychological function and to the reduction of tiredness and fatigue.
- Capsule count and serving size. Work out the cost per day, not just the price on the pot.
- Manufacturing standards. Look for GMP certification and clear country-of-origin information.
- Dietary suitability. Check for vegan, vegetarian, halal or kosher status if that matters to you.
How activGen's Magnesium Complex is put together
Our Magnesium Complex – Calm & Recover brings together three forms of magnesium — glycinate, malate and taurate — alongside vitamin B6 and zinc. It comes as 90 capsules at £9.99, is GMP certified and made in the UK, and is suitable for vegan, vegetarian, halal and kosher diets.
The reason we use three forms is simply choice: rather than committing to a single chelate, the complex offers a blend in one daily capsule. As with any supplement, it is intended to complement — not replace — a varied and balanced diet and a healthy lifestyle.
What pairs well with magnesium?
If you are building a simple daily routine, two other activGen staples are worth a look. Our Vitamin D3 + K2 Drops are a popular companion — vitamin D contributes to the maintenance of normal bones and to the normal function of the immune system. And our Omega 3-6-9 Oils provide EPA and DHA, omega-3 fatty acids that many people choose to top up.
Frequently asked questions
Is magnesium glycinate better than other forms?
There is no universally "best" form. Glycinate is a chelated form that many people find gentle on the stomach, which is one reason it is so popular. The right choice depends on how you tolerate it and how much elemental magnesium the product provides.
When should I take magnesium?
There is no required time of day. Many people take it with or after a meal for convenience and consistency. Always follow the dosage stated on the label.
Can I get enough magnesium from food?
Magnesium is found in leafy green vegetables, nuts, seeds, wholegrains and pulses. A varied, balanced diet is the foundation; a supplement is simply a way to top up if you feel your diet may fall short.
Is the Magnesium Complex suitable for vegans?
Yes. activGen's Magnesium Complex is suitable for vegan, vegetarian, halal and kosher diets, and is manufactured to GMP standards in the UK.
How much magnesium is in one serving?
Always check the supplement information panel on the pack for the elemental magnesium content per serving, as this is the figure that tells you how much magnesium you are actually getting.
