Is magnesium L-threonate right for me?

The magnesium L-threonate provided in Thorne Cognitive Vitality is a good choice for individuals looking for a highly absorbable form of magnesium to support brain health and cognitive performance, while helping to meet overall magnesium needs.*

What testing does Thorne complete for Cognitive Vitality?

We test this supplement for identity, purity, and potency to meet our strict quality standards. NSF Certified for Sport® products have been third-party tested to ensure the absence of nearly 300 substances banned by major athletic organizations.

What’s the difference between magnesium L-threonate and magnesium glycinate?

Magnesium L-threonate, or magnesium threonate, is bound to threonic acid, a derivative of vitamin C, and supports a healthy brain .* Magnesium glycinate is magnesium bound to two glycine molecules and supports restful sleep and muscle relaxation.*

Can magnesium L-threonate help with brain fog?

Brain fog is typically characterized by difficulty concentrating and mental fatigue. Magnesium L-threonate has been studied for its benefits on overall cognitive function, including mental alertness, focus, and attention.*

When will I see results from magnesium L-threonate?

Everyone’s body is different, and therefore, the timeframe can vary depending on your individual health, lifestyle, and type of supplements you’re taking. Supplements work gradually to support long-term health.
