"Simply Amazing!"

"I am so impressed by the science and effectiveness of three products I've been taking. The chewable multivitamin has a good taste which makes it so convenient to take. I've also taken both magnesium supplements and while they both improve my sleep,
feel the difference with the Magtein. It's as if my brain just feels relaxed yet focused at the same time. I know that's not an apt description but it's how I actually feel. So grateful for all the dedication and formulas."

Thank you so much for sharing your experience with us! We're thrilled to hear how impressed you are with our products. It's wonderful to know that our chewable multivitamin is not only convenient but also tasty for you. And we're delighted that our magnesium supplements, especially Magtein, have made such a positive impact on your sleep and mental clarity. Your description of feeling relaxed yet focused is fantastic feedback—it really helps capture the unique benefits of our formulas.
Best of health to you!

Methyl-Life® 5 Methylfolate 5 mg – Clinically-Backed Support for Cognitive Health, Methylation & Mood Balance

Methyl-Life® 5 Methylfolate 5 mg delivers a moderate-strength dose of bioactive folate — also known as 5-MTHF or L-Methylfolate — the most absorbable form of folate for the body. Specially formulated for individuals with MTHFR gene variants, this supplement supports healthy methylation, cardiovascular function, brain health, and neurotransmitter production without relying on the body's ability to convert synthetic folic acid.

If you struggle with folate absorption, mental fatigue, mood imbalances, or elevated homocysteine levels, this supplement may help you experience the benefits of folate faster and more efficiently.

Understanding the MTHFR Mutation and Folate Deficiency

Many people dealing with fatigue, brain fog, or mood imbalances don’t realize a genetic mutation could be interfering with how their body processes folate. The MTHFR gene plays a crucial role in converting folic acid into L-Methylfolate, the active form the body actually uses.

When MTHFR is mutated, this conversion becomes impaired.
