Suitable for adults 18+ only. Powder format — no scoop provided. Use accurate kitchen scales for weighing.
🧬 What Is Magnesium L-Threonate?
Magnesium L-threonate is a magnesium salt formed by combining elemental magnesium with L-threonic acid — a water-soluble compound that is naturally produced as a metabolite of vitamin C (ascorbic acid). The chelated structure binds two L-threonate molecules to one magnesium ion, creating a stable food-grade magnesium compound with a molecular formula of C₈H₁₄MgO₁₀ and a molecular weight of 294.50 g/mol. The magnesium content of the resulting compound is approximately 7.5% by weight — meaning the bulk of the molecule is the L-threonate component, with the elemental magnesium representing the actively claimable nutrient.
Within the family of magnesium chelates supplied as food supplements, L-threonate sits alongside other amino acid chelates such as magnesium bisglycinate (~16% elemental Mg), magnesium taurate (~9% elemental Mg) and magnesium aspartate (~8% elemental Mg). Each form has its own elemental magnesium percentage and physical handling characteristics. L-threonate is supplied as a fine, free-flowing white crystalline powder that is soluble in water and stable at standard storage temperatures.
Important note on health claims: Under retained Regulation (EU) No 432/2012, only elemental magnesium carries authorised UK NHC Register health claims. The L-threonate chelate format does not have any separate authorised claims of its own. All marketing claims for this product are attributed to the elemental magnesium content. Charge Products does not make any unauthorised claims relating to brain function, cognitive performance, memory, learning, blood-brain barrier penetration, or any other claim that has not been authorised by UK regulators.

What is magnesium L-threonate?
Magnesium L-threonate is a specialist amino acid magnesium chelate — a magnesium salt formed from elemental magnesium and L-threonic acid (a metabolite of vitamin C). The chelate contains approximately 7.5% elemental magnesium content by weight.
How much elemental magnesium does this powder provide?
Approximately 7.5% by weight (~75mg elemental magnesium per gram of L-threonate powder). A typical 2g daily dose provides approximately 150mg elemental magnesium (40% NRV). NRV stands for Nutrient Reference Value — the daily intake recommended for an average adult.
What does magnesium do?
Magnesium has 10 authorised UK GB NHC Register health claims when consumed at sufficient elemental magnesium intake. The most relevant include: magnesium contributes to normal functioning of the nervous system, normal muscle function, normal energy-yielding metabolism, reduction of tiredness and fatigue, normal psychological function, and electrolyte balance. These are official UK authorised claims — not marketing language.
How is this different from magnesium glycinate or citrate?
Different magnesium chelates have different elemental magnesium percentages. Glycinate is ~16% elemental Mg, citrate ~16%, oxide ~60%, taurate ~9%, L-threonate ~7.5%. The form determines the gram amount needed to provide a given elemental magnesium dose. All forms activate the same set of 10 authorised UK NHC magnesium claims when elemental magnesium intake meets NRV thresholds.
How much should I take daily?
Suggested daily intake is 1g–2g of magnesium L-threonate powder, providing ~75mg–150mg elemental magnesium (20%–40% NRV). Do not exceed 2g per day. Always weigh accurately using digital kitchen scales. Do not stack with other magnesium supplements without checking total magnesium intake — UK supplement upper limit for elemental magnesium is 250mg/day.
When should I take it?
Take with food. Mix the weighed powder into water, fruit juice or a smoothie. Some users prefer to split the daily dose into morning and evening portions. Avoid taking at the same time as iron supplements or zinc supplements as minerals can compete for absorption.
Is this powder vegan?
Yes — magnesium L-threonate is produced via chemical synthesis (not from animal sources). The powder contains only the L-threonate compound with no animal-derived ingredients, fillers, binders, or excipients.
Who should NOT take this?
Not suitable during pregnancy or breastfeeding without GP advice. Not suitable for under 18s. Not suitable for people with kidney disease or impaired renal function — magnesium can accumulate dangerously in renal impairment. Consult your GP before use if you take prescription medication, particularly bisphosphonates, tetracycline antibiotics, quinolone antibiotics, levothyroxine, or other mineral supplements.
Can I get a Certificate of Analysis (CoA)?
Yes — CoA available on request for any batch. Documentation includes purity verification (≥99%), elemental magnesium content (~7.5%), heavy metals testing, and microbiological analysis. Particularly relevant for trade buyers and contract manufacturers requiring batch verification for white-label products.
How do I store the powder?
Keep sealed in the original foil pouch below 25°C, away from direct sunlight and moisture. Re-seal after each use. Properly stored, the powder has a shelf life of 2 years from the date of manufacture. Keep out of reach of children.
Can magnesium L-threonate cause side effects?
As with any magnesium supplement, possible side effects include gastrointestinal symptoms such as loose stools, abdominal discomfort or nausea — these are typically dose-dependent and resolve on dose reduction. Reduce daily intake or split into smaller doses if these occur. Discontinue use if any adverse reaction persists and consult your GP.
Do you offer wholesale or bulk supply?
Yes — wholesale and bulk supply available for UK retailers, contract manufacturers, white-label brands and trade buyers. Standard pack sizes plus custom bulk volumes (1kg, 5kg, 10kg, 25kg) on enquiry. Custom labelling and private-label finished product welcome.
Is magnesium L-threonate the best form of magnesium?
No single magnesium form is universally "best" — different chelates have different elemental magnesium percentages and physical handling characteristics. Magnesium glycinate is well-tolerated and has higher elemental magnesium content (~16%). Magnesium citrate is similarly well-absorbed (~16% elemental Mg). L-threonate is a specialist amino acid chelate format. All forms activate the same authorised UK NHC magnesium claims at the same elemental NRV thresholds.
