Top-Notch Quality I Can Trust!

Knowing that these products are 3rd party lab-tested in an FDA-registered facility gives me peace of mind. I'm always confident in what I'm putting into my body, and I feel the results daily—better immunity, more energy, and less stress. Nutri has gained a loyal customer in me.

Unbelievable Results!

I've tried many supplements before, but nothing compares to the impact of GlyNAC-ET. Within just a few weeks, I noticed improved focus, more energy, and a significant boost in overall well-being. The fact that it's 20x more bioavailable makes all the difference! Highly recommend it for anyone serious about their health.

Amazing Supplement

I've been using GlyNAC-ET for about two months, and it's made a huge difference in my energy levels and overall health. My workouts are stronger, and I feel more focused throughout the day. Plus, the lifetime satisfaction guarantee is such a great bonus. It's easily the best supplement I've ever used.

Frequently Asked Questions

What makes L-threonate different from other magnesium forms?+
It is the only form shown to meaningfully raise magnesium levels in the brain. Oxide, citrate and even glycinate raise body magnesium but cross the blood-brain barrier poorly, which is why L-threonate is the form used in the cognition and sleep trials.
How much elemental magnesium is in a serving?+
144 mg of elemental magnesium from 2,000 mg of magnesium L-threonate per 2 g scoop. Elemental content is low by design — the point of this form is where the magnesium goes, not how much of it there is.
How do I take it?+
For cognition: half a scoop in the daytime and half a scoop before sleep. For sleep, mood or stress: half a scoop about an hour before bed. It is tasteless and clear in water.
How long until it works?+
Sleep and evening calm often shift within two to three weeks. The cognition trials ran twelve weeks, so give memory and focus benefits a couple of months of daily use.
Why powder instead of capsules?+
A full 2,000 mg dose takes about four large capsules. One scoop of tasteless powder in water is faster, cheaper per serving, and lets you split the dose between morning and evening.
Which size should I buy?+
The 120 g tub is 60 servings and the better value per serving. The 60 g tub is 30 servings, which is the sensible way to try it first.
