Magnesium L-Threonate 2000mg | Brain & Sleep Support

Each three-capsule serve contains 2,000 mg of magnesium L-threonate, the compound used in the clinical trials. Magnesium L-threonate is about 7% elemental magnesium by weight, so that works out to approximately 144 mg of elemental magnesium per serve. The label lists the compound weight, which is the figure used in the research. If you also take another magnesium supplement, count both towards your daily total.

Take three capsules daily with a meal. If sleep is your priority, take all three in the evening, one to two hours before bed. If you want daytime focus, split the serve: two capsules with breakfast and one in the evening. Consistency matters more than timing; the benefits seen in trials built up over several weeks of daily use.

Sleep changes are usually the first thing people notice, often within the first one to three weeks. In a 2024 randomised trial, adults with self-reported sleep problems reported better sleep quality and daytime functioning after 21 days. Cognitive benefits take longer: the 12-week trial in older adults measured improvements at 6 and 12 weeks. Give it a full bottle (30 days) before judging, and ideally three months of consistent use.

Yes. It pairs naturally with NMN for cellular energy and with Korean Red Panax Ginseng or Methylene Blue for daytime focus, and it makes a sensible evening anchor for any longevity routine. Because the L-threonate carrier is gentle on the gut, it is far less likely to cause the digestive upset associated with magnesium oxide or citrate. If you take prescription medication, speak with your healthcare professional first.

Yes. The only ingredients are magnesium L-threonate, a vegetable capsule and rice flour, with no artificial fillers, colours or preservatives, so it is suitable for vegans and vegetarians.

It is intended for adults. Do not use if pregnant or breastfeeding unless your doctor advises it, and check with your healthcare professional first if you have a kidney condition or take medication, as magnesium can interact with some antibiotics, bisphosphonates and diuretics. Stop use and consult your doctor if you experience any adverse reaction.
