What is Magnesium L-Threonate?

Magnesium L-Threonate is a special form of magnesium linked to L-threonic acid. L-threonic acid is a metabolite in the body involved in the metabolism of vitamin C. This combination improves the absorption of magnesium in the body, making it a popular choice for those looking to increase their magnesium levels. Magnesium L-Threonate stands out from other forms of magnesium due to its unique property of enhanced bioavailability, particularly its efficient passage through the blood-brain barrier.

It is chosen by a diverse group of people, from students and professionals to the elderly, all looking for dietary supplements to support their daily activities.

Magnesium L-Threonate has a special connection with GABA, a crucial neurotransmitter for calming and relaxation. Magnesium is generally known as a natural relaxant, partly due to its interaction with GABA receptors. This interaction enhances the calming effect of GABA while simultaneously reducing the release of stress hormones.

In a broader sense, magnesium is known to be involved in the production and function of neurotransmitters, including the biosynthesis (creation) and transmission (transfer) of these important chemicals in the brain. It also plays a role in maintaining the balance between GABA and glutamate, the latter being a more stimulating neurotransmitter. Additionally, people with higher magnesium levels have been observed to have healthy amounts of serotonin in their cerebrospinal fluid, and the synthesis of dopamine requires magnesium.

Through these mechanisms, magnesium helps support overall mental and cognitive health. Magnesium L-Threonate, with its ability to cross the blood-brain barrier more effectively, can theoretically be particularly useful in enhancing these aspects by increasing magnesium availability in the brain.

Why buy AvantVital’s Magnesium L-Threonate?

Triple dosage for consistent absorption

Taking magnesium throughout the day, spread over several moments, is recommended to maintain a constant magnesium level in the body. By dividing magnesium into smaller doses throughout the day, rather than taking one large dose, the body can absorb and use the mineral more efficiently. AvantVital’s Magnesium L-Threonate capsules, each with 667 mg, make it easy to follow this regimen, with the possibility of dividing the recommended daily dosage of 2000 mg into three moments. This helps avoid potential digestive issues that can arise from taking large amounts of magnesium at once and ensures that the body has a stable level of magnesium throughout the day. This can be particularly useful for supporting various body functions that depend on magnesium.

Suitable for vegetarians, easy to swallow & free from unhealthy additives

AvantVital’s Magnesium L-Threonate is encapsulated in vegan HPMC capsules. HPMC stands for hydroxypropyl cellulose, made from cellulose. The substance is extracted from wood. Cellulose is essentially an indigestible plant fiber and is recognized as such by our body. HPMC is similar to cellulose but is much more soluble and considered safe for human consumption.

AvantVital’s Magnesium L-Threonate contains minimal amounts of gluten-free organic rice flour and magnesium stearate, used as filler and anti-caking agent respectively, to ensure a consistent dosage in each capsule, free from unnecessary additives.

Usage & Ingredients

The optimal dosage of Magnesium L-Threonate may vary depending on individual needs and the advice of a health professional; the recommended dosage is usually between 1200 mg to 2000 mg per day, with our capsules each containing 667 mg of Magnesium L-Threonate. This suggests using two to three capsules daily, tailored to your personal needs.

Magnesium L-Threonate can be taken with or without food, although some prefer taking it with food to avoid potential stomach discomfort. Adjust the intake according to your body’s signals for optimal comfort.

As for the timing of intake, it is advisable to spread the doses evenly throughout the day – for example, in the morning, afternoon, and before bed. This helps maintain a constant level of magnesium in the body. Regular use is recommended, but it may be wise to take a break after a few months of consistent use.

Always consult with a health professional before starting Magnesium L-Threonate, especially if you are undergoing medical treatment, pregnant, or breastfeeding.

Pay attention to your body’s response to the supplement. If you experience any adverse effects, discontinue use and consult a health professional.

It is also recommended to consult a health professional before starting Magnesium L-Threonate, especially if you are pregnant, breastfeeding, taking medications, or have a medical condition.


There is limited specific information on the interaction between Magnesium L-Threonate and medication. Nevertheless, individuals taking medications are advised to consult with a health professional before starting new supplements, including Magnesium L-Threonate. This is particularly important for individuals taking medications that affect muscle function, blood pressure, or the absorption of other medications, as Magnesium L-Threonate could theoretically interact with these medications. Consulting with your doctor or a qualified health professional can ensure safe and appropriate use of Magnesium L-Threonate in your specific situation and help prevent potential negative interactions with medications.
