Key Feature & Benefits

GlyNAC combines glycine and N-acetyl cysteine, supplying building blocks for glutathione. A small 16-week trial in older adults reported improved glutathione and several functional measures. A larger two-week trial did not improve its primary glutathione outcome overall. These studies did not test this Aeternum product; they do not guarantee improved energy, strength or lifespan. Read both studies in the description.

Description

GlyNAC Powder — Building Blocks for Glutathione

Give your body the building blocks for glutathione. Aeternum GlyNAC combines glycine and N-acetyl cysteine, which supplies cysteine. Glycine and cysteine are two of the amino acids used to make glutathione, an antioxidant produced by the body.

One powder. Two ingredients.

  • 2,000mg glycine plus 2,000mg NAC per labelled 4g serving
  • 120g and 360g packs; 30 and 90 labelled servings respectively
  • No added fillers, flavours or preservatives, as listed on the label
  • A Canada-specific 120g option is available; select the variant for your destination

The research behind GlyNAC

A small 16-week randomized trial in older adults reported improvements in glutathione levels and several measures of physical and metabolic function. A larger two-week trial did not improve its primary glutathione outcome overall, although an exploratory subgroup analysis suggested benefit in participants with greater need. Results depend on population, dose and duration; these were not trials of this Aeternum product. 16-week trial · Two-week trial.

NAC naturally has a strong sulphur-like smell and flavour.

Science-Backed Supplement

I learned about GlyNAC from some research papers on longevity. This supplement lives up to the hype. I feel healthier and more energetic overall. It's like giving my cells the fuel they need to function better. I'll continue using it as part of my longevity stack.

Improved Bloodwork

My latest bloodwork showed improved liver values and I think this GlyNAC had something to do with it. I've been taking it daily for a couple of months. I also feel more alert and my sleep quality has improved. It's a supplement I'll keep in my routine for the long run.

Great for Workout Recovery

I've started using this GlyNAC blend to help with my gym recovery. It’s been two weeks and I already feel less muscle soreness after intense workouts. My endurance during exercise has improved too. It mixes well in my post-workout shake and doesn't taste bad at all.

Surge in Energy

This GlyNAC powder gave me a noticeable surge in energy. My mind feels clearer and I don't get as tired during the day. I've been taking it for a month and even my productivity at work has improved. I'm really pleased with the results so far.

Sleep Quality Up

Surprisingly, my sleep has gotten better since I started GlyNAC. I take it in the evening and I fall asleep faster and sleep deeper. I read that glycine can help with sleep, and it seems true for me. Plus, during the day I have steady energy. Win-win!

Convenient Combo

This powder is a convenient way to get both glycine and NAC at once. I used to take separate pills, but this is much easier and more cost-effective. I've noticed my recovery from workouts is faster and I don't feel as much fatigue. Great product for anyone into fitness and health.

Health Boost

I love the health benefits I'm getting from this powder - more energy and I feel generally healthier. The only downside is the taste; it's a bit sulfuric due to the NAC. I learned to mix it in a strong flavored juice to mask it. Small price to pay for the boost it gives me.

More Pep in My Step

Ever since I added this to my daily regimen, I have more pep in my step. I'm in my late 40s, and I feel more like I did in my 30s. It mixes easily with water or juice. I usually take it first thing in the morning and it keeps me feeling balanced throughout the day.

Wish It Had a Scoop

The product itself is great - I feel more energetic and even my skin seems to have a bit of a glow. My only wish is that it came with a scoop for easier measuring. I had to use my own teaspoon. Other than that minor inconvenience, I'm very happy with the results.

Good for Healthy Aging

I read about GlyNAC in an article on healthy aging and decided to try this. So far, I feel a subtle improvement in my overall energy and mental clarity. It's not an overnight miracle, but day by day I am feeling better. I'm happy knowing I'm doing something good for my cells.

Helping My Parents

I bought this GlyNAC powder for my parents who are in their 70s. After a month, they both report feeling more energetic and mentally sharp. My mom says she can do more housework without getting tired. It's great to see them so lively. We're all impressed with this supplement.
