Frequently Asked Questions

How is magnesium bisglycinate different from other forms?

Bisglycinate is chelated to amino acids, making it up to 5x more absorbable than cheaper forms like magnesium oxide. It's also gentle on the stomach and won't cause digestive upset or laxative effects that other forms can cause.

When should I take magnesium bisglycinate for best results?

Take 2 capsules 30-60 minutes before bedtime with or without food. The gentle formula won't upset your stomach, and taking it before bed maximises the sleep and relaxation benefits whilst supporting overnight muscle recovery.

How quickly will I notice the benefits?

Many customers report better sleep quality within the first few nights. Energy improvements and reduced muscle tension typically become noticeable within 1-2 weeks of consistent use as your magnesium levels optimise.

Is this suitable for vegetarians and vegans?

Yes, absolutely. Our magnesium bisglycinate is completely vegan-friendly, made with plant-based capsules and contains no animal-derived ingredients. It's also free from gluten, dairy and artificial additives.

Can I take this alongside other supplements or medications?

Magnesium bisglycinate is generally well-tolerated with other supplements. However, if you're taking medications (especially antibiotics or heart medications), consult your healthcare provider first as magnesium can affect absorption timing of certain medications.

Is Magnesium Bisglycinate good for muscle cramps?

Absolutely. Magnesium is well-known for supporting muscle function and easing cramps. It’s involved in hundreds of bodily processes, including nerve and muscle function.

    Night time sleep!

    I purchased Magnesium Bisglycinate as I am in peri menopause and I have been waking up extremely early in the morning, but finding it hard to sleep at night.

    The product worked for me. I take the capsules with water 30min before bed and I get a good nights sleep 8 hours rest. Yipee!

    So far so good

    Bought the product as I thought it might help with aching bones and I was taking an alternative cream product made in UK by a small team called Sweet Bee. Excellent product and can’t fault it, but I wanted something to swallow it all my other Purolabs vitamins.

    As far as I can tell (and hope I don’t catch a virus) I’ve been in near contact with friends with flu type symptoms and other mild cold illnesses and so far not caught anything. I believe this is due in part to these equally excellent vitamins giving my body some protection above the normal immune system we have built in naturally.

    These are the Purolavs I take every morning.

    Great team. Always helpful.

    The best Magnesium formula

    I’m happy with the magnesium glycine from the Purolabs . I tried lots of magnesium from different companies and this is the only formula which helps me with my insomnia. Thank you Purolabs!

    I’ll definitely reorder in future.
