FAQ

Magnesium L-threonate is a form of magnesium bound to L-threonic acid. Unlike common forms, it is the only magnesium shown to meaningfully raise magnesium levels in brain tissue, which is why it is used for focus, memory and calmer sleep rather than muscles or digestion.

Most magnesium raises levels in the blood but does not cross into the brain. L-threonate is the exception. That is why people who felt nothing from generic magnesium often notice a difference with L-threonate.

THREON is magnesium L-threonate at 99% purity, and every batch is lab tested. A certificate of analysis confirms identity, purity and safety testing for heavy metals and microbes for each batch.

The active ingredient is identical. The powder gives you full control of the dose and dissolves fast, while the capsules give an exact dose with no measuring. Choose powder for flexibility, capsules for simplicity. See our guide on powder or capsules.

No. THREON is pure magnesium L-threonate with no fillers, bulking agents or unnecessary additives.

Magnesium contributes to normal psychological function, the normal working of the nervous system, and the reduction of tiredness and fatigue. People typically choose L-threonate to support focus, memory and calmer, deeper sleep.

Many people report calmer sleep within the first week or two, with focus building over the following weeks. It works best taken consistently rather than occasionally, so give it a few weeks before judging it.

More vivid, memorable dreams usually reflect more time in deep, dreaming sleep. It is a common and harmless sign that tends to settle as your body adjusts. If it feels too strong, take your dose a little earlier in the evening.

Neither. It is not a stimulant and will not force you awake, and it is not a sedative that knocks you out. It supports the calm and normal nervous system function that help you wind down naturally.

Follow the dose on your pack. As a guide, two scoops of powder (around 2,000 mg of L-threonate) or three capsules (3 x 800 mg) per day. More is not better.

In the evening, about one to two hours before bed. Magnesium supports calm and winding down, so this timing suits most people. See how and when to take it.

Either works. It is well tolerated with or without food. If your stomach is sensitive, a small snack can feel gentler. Daily consistency matters more than timing with meals.

Yes to daily use within the recommended dose, and no, it is not habit-forming. Magnesium is an essential nutrient your body uses every day, not a drug, so there is no tolerance or withdrawal.

Generally yes. Magnesium pairs well with a normal supplement routine. If you take other magnesium products too, keep the combined amount sensible and within pack guidance, and ask a pharmacist if unsure.

Magnesium L-threonate is well tolerated. The most common effect of taking too much is loose stools, which is a signal to lower the dose. Stay within the amount on the pack.

Magnesium can affect how some medicines are absorbed, including certain antibiotics and thyroid, blood pressure or heart medication. Speak with your doctor or pharmacist before combining, and separate the timing if advised.
