BIOAVAILABLE FORM -

the amino acid glycine enhances bioavailability by utilising the absorption channels of amino acids in the small intestine

GENTLE ON THE GUT -

the enhanced bioavailability of chelated magnesium glycinate leads to less unabsorbed magnesium reaching the large intestine where it can otherwise have a laxative effect

Bioavailable form

Magnesium glycinate is a bioavailable and stable form consisting of magnesium bound to the amino acid glycine. This chelated form protects the magnesium from binding with other substances in the digestive tract, which could reduce its absorption. Glycine also improves magnesium uptake by utilising the natural absorption channels of amino acids in the small intestines.

Meaningful dose

To ensure the dose of magnesium is optimal for health, we recommend taking 2 capsules per day, delivering a dose of 380mg elemental magnesium derived from 1300mg bulk magnesium. This provides 100% of the Nutrient Reference Value per serving. The tub provides a 90-day supply when taking the recommended 2 capsules a day. Split dosing magnesium improves uptake; for optimal absorption and all-day coverage, we recommend splitting the daily dose between morning and evening.

Gentle on the gut

As magnesium glycinate is chelated, it does not typically have a laxative effect or cause digestive upset, because of the way it is bonded to the amino acid glycine. Chelated magnesium is more likely to be absorbed earlier in the digestive tract, reducing the amount of unabsorbed magnesium entering the large intestines. Poorly absorbed forms draw water from the cells lining the large intestines, acting as a laxative.

Supporting mood & sleep

Magnesium is one of the essential nutrients required for neurotransmitter production and regulation, including feel-good serotonin, rewarding dopamine, calming GABA and sleep-inducing hormones. Magnesium also supports the nervous system and normal psychological function, including concentration, learning and memory. Without adequate magnesium, the brain may struggle to perform these tasks efficiently, and suboptimal levels are often associated with low mood and irritability.

Muscle function & energy

Magnesium is required for cell division; therefore, it’s essential to build body tissue, including skin and muscle. It also plays a role in recovery after exercise. Required for muscle function, magnesium allows for contraction and relaxation of muscles, as well as supporting the muscles of the heart and regulating the heartbeat. Essential to energy production, magnesium plays a crucial role in converting carbohydrates, proteins and fat into energy for the cells.

Bone health

Magnesium is required for converting vitamin D to its most active form, in turn supporting calcium absorption. Both calcium and magnesium are important for the health and maintenance of bones and teeth, with around 52% of the body’s magnesium stored in bones. With 40% of peak bone mass formed during adolescence, it is clear that magnesium is not just important for later life, but also early on to support the prevention of disease.

Great supplement

Love this magnesium, good dosage. Capaules are quite big - so be aware of it, but can be opened. I use it for relaxation and sleep, can see the difference.

Brilliant

Brilliant easy to order and delivery. Great tablets for helping to sleep.

This is a high-quality product for a very reasonable price

This is a high-quality product for a very reasonable price, and I will be ordering it again.

Good

Arrived quickly but haven't managed to try them yet. Expect Good things as all other products ive tried from here have been.

An excellent product

I recently started taking Igennus Magnesium glycinate. I ordered over the phone and received good advice before buying. It arrived promptly. I find the tablets easy to swallow and started noticing in the first week that I am sleeping better. This is the reason I bought it, so I am delighted.

Helps with sleep, but capsules too big

I feel my sleep has improved since taking this. The only issues is that the capsules are bigger than the other magnesium products from the same brand, which makes them harder to swallow. I need to open the capsules instead.

Upgraded to these from another magnesium

Upgraded to these from another magnesium supplement and these are a much better composition

Improved sleep

I have noticed an improvement with my sleep since starting this.

Good price for a biglycinate

Good price for a biglycinate that I feel I can trust.
Gentle on the stomach, good bio available form to help with muscle relaxation and sleep.. I take in the evening for these benefits and find them to help.

Awesome Customer Service, Fast Delivery and I am Satisfied with my supplements being CLEAN LABEL. Pricing was also reasonable. 👍😎

Professional and knowledgable

Always so helpful and efficient. Thank you

Take these to help me sleep better and been very happy with them

Great product!

Great product and fast delivery thank you

Finally, a restful night's sleep!

I've been taking these vegan Magnesium Glycinate capsules for about three weeks now, and my sleep quality has noticeably improved. I used to have a restless mind at night, but I now feel more at ease and wake up feeling refreshed. The capsules are neutral in taste and gentle on my stomach, which was a big concern for me. Highly recommend for anyone looking for a natural way to support relaxation."

Great product

Excellent product to add to your stack

No regret

I am extremely satisfied with this High Strength Magnesium Glycinate. Unlike other magnesium supplements I've tried before, this buffered chelate formula is very gentle on my stomach and hasn't caused any digestive issues or diarrhea.
I've also noticed a significant improvement in my sleep quality since I started taking it. It's vegan, high-potency, and truly effective. Highly recommended for anyone looking for a reliable magnesium source!

Excellent, high quality magnesium which really works !!

I was introduced to this high strength Magnesium Glycinate by a friend as I was not sleeping well after coming off HRT. Within a few weeks I could really tell the difference, I was sleeping well, felt calmer & happier than I had done in ages.
I highly recommend this product to anyone coming off HRT & in general for all the other benefits as listed.
My husband has also started using it (we take 2 tablets before going to bed) & he is sleeping like a baby !!

Reliable product

I have been using Igennus products for years, and I am very happy with them. This product is no exception. I believe it is important to take magnesium, and it is crucial to choose high-quality products. My husband has experienced fewer muscle cramps since using this product.

Promising

Family have also taken the magnesium and sister has reported rested nights and helps to calm me

Magnesium glycinate

This brand is one of the best. Love it

Trusted magnesium glycinate brand

I'm guided to try magnesium glycinate to target anxiety and insomnia.. in truth, I stay up too late, while the anxiety is all too real; good sleep helps everything.
What I don't worry about with igennus product, is quality; I can trust it is exactly as described.
I cannot report a magical improvement, but nor do I try to assess this - it is enough that I take magnesium glycinate and know it contributes to my wellbeing.
No adverse effects to report, though all magnesium tends to reduce any constipation - this is beneficial to most, if some people may best stick to one capsule per day.

Makes a difference

Compared to magnesium malate and Taurate, I find this form of magnesium allows me to have uninterrupted sleep. One star off because the capsules are large - which is unavoidable.

Helps Me with Sleep

I have taken magnesium from Igennus for many years to help with my sleep struggles. It definitely helps me as if I forget to take it, I struggle more so to drop off. I also like their triple magnesium complex which I prefer as I exercise a lot and I believe that supplement is more suited to me.

Great magnesium!!

I have taken Magnesium supplements for years and tried many different forms & brands, but since trying this one a few months ago, I have a new favourite. It's highly absorbable, gentle on the stomach and works brilliantly for my needs. Magnesium is particularly good for when menopause symptoms start to appear & I can also highly recommend Igennus' new multivitamin for women 50+ to take alongside. Both have helped hugely with energy & sleep.
I have been recommending this magnesium to family & colleagues, who are also very happy with it for it's ability to help muscle recovery/cramps & sleep quality.
Compared to other brands of magnesium glycinate I have taken, the cost of this one is extremely reasonable for the quantity & dosage.

Excellent

I was given this to trial and thought it’s an excellent source of magnesium which I used to help with relaxation and sleep. Extra bonus that it’s vegan especially as I am now transitioning to a raw vegan diet. Will definitely buy this.

Magnesium Glycinate

This is a useful supplement as it helping me to sleep better. That seems to be the main benefit of the supplement.

A great high strength glycinate option

As with other Igennus products I’ve used, the quality and formulation of this magnesium are excellent. I appreciated the guidance to split the dose, which shows real thought about absorption and tolerance.

I encountered no digestive issues while taking this magnesium, but still experienced a small amount of muscle cramping, so I’ve gone back to the Igennus Triple Magnesium Complex which suits me better. That said, this is clearly a very well-made, high-strength glycinate option and Igennus remains one of the supplement brands I trust most for quality and transparency.

Loved these

I prefer to stick to brands I know and trust like ingennus and these magnesium capsules are great, a good strength dose, they help with my sleep and also feel like I get to sleep more quickly

Super product

I take two in the evening and sleep straight through, on the occasions I have forgotten I am back to waking in the night.
