About This Product.

Magnesium Glycinate Capsules deliver magnesium in its chelated glycinate form — one of the better-absorbed oral forms of the mineral, and the one most commonly chosen when the goal is sleep quality, nervous system calm, or muscle recovery rather than simple repletion.

Magnesium is a cofactor in hundreds of enzymatic reactions, including those governing neurotransmitter regulation, protein synthesis, and the management of cortisol. Many adults fall short of adequate intake through diet alone, and suboptimal magnesium status is associated with poor sleep architecture, low mood, and muscle cramping — particularly in people under sustained physical or mental stress.

Magnesium glycinate is generally well-tolerated in the gut compared with oxide or sulphate forms, which can have a laxative effect at higher doses. The glycinate carrier itself is an inhibitory amino acid that may add to the calming profile, though the evidence here is still developing.

This format suits people who have confirmed low magnesium via a blood test, those in heavy training blocks, individuals with consistently poor sleep unrelated to sleep hygiene, and anyone whose diet is low in nuts, seeds, and leafy greens. It also sits well within a broader cognition-support routine given magnesium's role in NMDA receptor function and neuroplasticity. Follow the dosage on the packaging, and take with a clinician's awareness of your full supplement stack.

High-absorption magnesium for sleep & recovery

Magnesium Glycinate Capsules

How to Take It

i.

Follow the dosage on the packaging. Magnesium glycinate is commonly taken in the evening with a meal or shortly before bed, which aligns with its use for sleep and recovery. If you are taking other supplements or medications, check with a clinician before adding it to your routine.

Frequently Asked.

How does magnesium glycinate differ from other forms of magnesium?

Magnesium is sold in many salt forms — oxide, citrate, malate, glycinate, and others. Glycinate is a chelated form, meaning the magnesium is bound to the amino acid glycine. This generally improves absorption and is less likely to cause the loose stools associated with oxide or high-dose citrate. It is the form most often chosen for sleep and nervous system support.

How long before I notice a difference?

If you are genuinely deficient, some people notice improvements in sleep quality or muscle tension within one to two weeks of consistent use. That said, magnesium is not a sedative — the effect is subtle and cumulative. A follow-up blood test after six to eight weeks is a reasonable way to confirm your levels have moved.

Who might not be suitable for this supplement?

People with kidney disease should not supplement magnesium without medical supervision, as the kidneys regulate magnesium excretion and impaired function can lead to accumulation. Those taking certain medications — including some antibiotics, diuretics, or bisphosphonates — should check for interactions with a clinician before starting.

Should I take it with food or on an empty stomach?

Magnesium glycinate is generally well-tolerated either way, but taking it with a small meal can reduce any chance of nausea, particularly when you are first starting. Many people prefer taking it in the evening given its association with sleep and relaxation.

Do I need a blood test before taking this?

It is not strictly required, but it is worth considering. Serum magnesium is a standard marker on a comprehensive blood panel, and knowing your baseline helps you understand whether you are actually deficient or simply supplementing without cause. If you would like to test before you start, we offer blood panels through the clinic.

Finally sleeping properly again

5 months ago

Been taking this for about six weeks now, started after a rough patch at work where sleep was all over the place. Within the first fortnight I noticed I was waking up less at 3am and actually feeling rested. I take two capsules about an hour before bed and it's become a non-negotiable part of my routine. No digestive issues at all, which was my concern after trying a different form a while back.

Solid addition to my stack

5 months ago

Running a fairly heavy training block at the moment and cramps were becoming a real issue in the evenings. These sorted it within a couple of weeks. Takes with my evening meals, stacks well with the zinc I already take.

NB

Good product, pricey for what it is

6 months ago

Genuinely noticed a difference in how settled I feel before sleep — less of that wired-but-tired feeling. My only gripe is that £77.50 is quite steep when you can find glycinate forms elsewhere for a fair bit less. I get that this is a curated range but it does give me pause on the repurchase. The capsules themselves are easy to swallow and I've had zero stomach upset.

Does exactly what it says. Sleep is deeper, less anxious in the evenings. Would buy again without hesitation.

Much gentler on the stomach than oxide forms

7 months ago

I'd tried magnesium supplements before and always had GI trouble — switched to this glycinate version on my GP's suggestion and the difference is night and day. No cramping, no urgency. I take it alongside an omega-3 and a B-complex and haven't noticed any issues. Sleep quality has improved noticeably, particularly in how quickly I drift off.

Quiet but effective

8 months ago

Not the most exciting supplement to talk about but it just works. I started taking it after a blood test flagged low-normal magnesium levels and my nutritionist recommended the glycinate form specifically. About a month in, sleep feels more consistent and afternoon brain fog has eased up a bit. Can't attribute everything to this one thing but it's staying in the rotation.
