Magnesium Bisglycinate

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.

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.

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.

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.

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.

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.
