## Features

- COGNITIVE FUNCTION: Magtein magnesium l-threonate is thought to cross the blood-brain barrier more efficiently compared with other forms of magnesium, allowing it to support the magnesium level of the brain, for memory, learning, and synaptic plasticity support. L-theanine supports alpha brain wave activity, for a relaxed but calm and focused mental state.
- NEUROPROTECTION: Magnesium l-threonate is considered potentially the most protective form for the brain, and apigenin supports brain health. All three ingredients work together to support long term brain function.
- SLEEP QUALITY: Magnesium l-threonate supports relaxation and calming of the nervous system, which may contribute to deeper sleep, while l-theanine promotes relaxation. Apigenin has been studied for its anxiolytic properties, including relaxation.
- STRESS SUPPORT: Both l-theanine and apigenin are compounds that support calming, and magnesium l-threonate supports overall relaxation and mood.
- SUPER CLEAN FORMULA: Compare to other magnesium l-threonate supplements - ours has no fillers, excipients or other additives. Our contains the patented Magtein form of magnesium l-threonate, is bottled in the USA in a cGMP-certified facility, and is 3rd party tested. Don’t settle for copycats when it comes to your health!

### ⭐⭐⭐⭐⭐ This is Good Stuff!
*by A***R on November 20, 2025*

This Magnesium L-Threonate Complex is new to me. I really like it because it has completely lifted my brain fog! I faithfully take it everyday. The recommended dose is three small capsules. There are absolutely no fillers, no hidden or artificial ingredients, or artificial colors. This is the first time I have ordered the “Why Not Natural” brand, and am impressed with its quality.
