Glycine and N-Acetyl Cysteine (NAC), collectively known as GlyNAC, represent a groundbreaking advancement in longevity science. These amino acids provide distinct individual benefits and, together, serve as crucial precursors to glutathione—the body’s “master” antioxidant. Glutathione is found in virtually every cell of the body and plays a critical role in maintaining cellular balance, supporting detoxification, neutralizing free radicals, and promoting healthy aging. By targeting multiple hallmarks of aging, GlyNAC has become a potent ally in the fight against time.*

The Power of Three

The combined action of glycine, NAC, and glutathione is central to GlyNAC's powerful effects. Research shows that GlyNAC supports healthy aging across several key areas.*

Boost Glutathione Levels*
 

Lower glutathione levels, along with the oxidative stress that comes with aging, are the result of deficient precursor amino acids.1 GlyNAC provides these crucial building blocks, enabling the body to naturally synthesize glutathione and support optimal levels of this vital antioxidant.*

Support a Healthy Antioxidant-Oxidant Balance*

Maintaining the right balance between antioxidants and oxidants is crucial for overall well-being. This balance not only helps protect against harmful free radicals but also ensures oxidants can perform their beneficial functions within the body.*

  • Supplementing directly with glutathione may disrupt this delicate equilibrium, especially if the body has difficulty using excess glutathione.*
  • By using precursors like GlyNAC, the body can naturally produce glutathione, adjusting levels in response to oxidative stress and cellular needs. This leads to a more efficient and balanced antioxidant response.*

Optimize Mitochondria*

Mitochondria are particularly rich in glutathione, which plays a crucial role in neutralizing the free radicals produced during energy production. Research indicates that GlyNAC can enhance the natural antioxidant defenses of mitochondria, helping to preserve cellular integrity and potentially slow the aging process.*2-4

Target the Root Causes of Aging*

GlyNAC has shown potential in addressing multiple hallmarks of aging through various mechanisms. Animal studies suggest GlyNAC not only improves mitochondrial function but also extends both healthspan and lifespan.2 Recent human studies, using over 6 grams of each component, show that GlyNAC improves key aging biomarkers, leading to gains in exercise performance and cognitive function.*3,4

Ingredient Info  

  • L-Glycine: An amino acid known for its calming effects. Supports glutathione synthesis, neurotransmitter function, and healthy sleep.*
  • N-Acetyl Cysteine (NAC): A stable form of the sulfur amino acid L-cysteine. Plays a crucial role in glutathione synthesis and respiratory health.*

How much weight are you carrying?

I’m very pleased with my 16lb weighted vest. Great quality. The straps are easy to adjust and the weight is evenly distributed when wearing. It really helps with your posture. Great way to ease in on training for backcountry hiking/camping.

Comfortable Fit & Great Added Challenge
Size: 8 Lb, Color: Black, Size: 8 Lb, Color: Black
Really impressed with this vest. It fits snug without being bulky and stays in place during walks and workouts. The weight feels evenly distributed, so it’s comfortable on my shoulders and back. I’ve been using the 8 lb option and it’s the perfect way to add a little extra challenge to my routine. Easy to put on, well made, and definitely worth it!

comfortable and works
Size: 10 Lb, Color: Black
Finally figured out how to wear this vest. There are two sides to the vest. When I put it on upside down, it fits much better and is comfortable. I bought the 10lb vest and although it feels heavy when you pick it up, its very comfortable when wearing it. If I put it on right side up it does not fit across my chest. But turned around it fits great and I am able to buckle it closed. I definately stand up straighter when wearing this vest and easy to walk around it. Although, as the weather gets hotter, it is a bit warm to wear.

ONE OF THE BEST ON THE MARKET AND GREAT PRICE!
Size: 24 Lb, Color: Pink, Size: 24 Lb, Color: Pink
I received my 24 pound vest today. I ordered pink. I love the color! Upon inspection, I see that the vest is very well-made, sturdy, with no metal beads leaking. It fits great. My previous vest hung down too low, resting on my hips. This one sits much higher, just like I wanted it too. This fits my body pretty great. I wore it inside my house to give it a try for two hours. It never shifted and I did not have to adjust it. However, the bulging sand pockets on my back, pressed against my shoulder blades and were a little bit bothersome, but not painful. I’m sure I’ll get used to it. I have purchased 5 rucking vests from 4 different manufacturers and this one, along with RuKSTR are the best. Unfortunately, RuKSTR does not make a 24+ lb weighted vest. Here are the stats of my body: 5’9” 142 lbs. 68 yrs old Bust = 38” Waist = 28” Midriff = 30” Top of shoulder to waist = 19” Shoulders end-to-end = 15”
