Awesome product!

Good quality product with the right proportion of ingredients and size. I have been taking this product for sometime now and am seeing the benefits especially at my age of 64 not losing my muscle mass with my workouts. Helps with my workout and training. I know alpha ketoglutaric acid helps in cell metabolism.

Great stuff; I was blown away by the difference I noticed after just one month of use. Definitely more energy and improved digestion. Long term, who knows, but it appears to be effective in the short term. I believe the calcium/magnesium buffering is beneficial. My stomach is sensitive, and acidic foods, for example, cause it to react. This gives me no difficulties, and I drink it with black coffee, which isn't exactly gentle on the stomach the way I prepare it. This substance was well-made and appears to be effective. It gives me enough energy that I want to resume my fitness programme.

Motivation booster

Akg has helped me with my motivational issues as a result of chronic infection. Ive tried a lot of things to boost ATP production and this made a noticeable difference in energy. Combines well with b-vitamins, NADH/NR and things like cordyceps. The pills are easy to swallow, but i open them and mix them in my amino acid powder mixture. No taste at all.

Alpha-Ketoglutaric Acid, 100 Capsules

I’ve been taking Kirkman Labs Alpha-Ketoglutaric Acid (300 mg, 100 capsules) for about a month, and I’m quite satisfied with the results. I take one capsule daily with a meal, as it’s gentler on the stomach this way, especially since alpha-ketoglutaric acid (AKG) can be acidic. The capsules are vegetarian, hypoallergenic, and free of common allergens like gluten, dairy, soy, and nuts, which is great for my dietary needs. I’ve noticed a subtle boost in energy and mental clarity, likely due to AKG’s role in the Krebs cycle and amino acid metabolism. My digestion also feels smoother, and I haven’t experienced any stomach discomfort, thanks to Kirkman’s buffered formula with calcium and magnesium salts. Some users report it helps with athletic performance and recovery, but I haven’t tested it extensively for that. The only downside is the capsules can sometimes stick together if not stored properly, so I keep them in a cool, dry place. I’d recommend this for those seeking energy and metabolic support, but consult a healthcare professional if you have high protein intake, gut issues, or are on medications.

Gentle Energy Support with Clean Ingredients

I've noticed a subtle boost in my overall energy levels. The capsules are easy to swallow and don't have any unpleasant aftertaste. I appreciate that this supplement is hypoallergenic and free from common allergens, making it suitable for my sensitive system. While the effects aren't dramatic, I feel more balanced and less fatigued throughout the day.

A very high-quality product. It works effectively in acetonemic conditions. Good composition. It is very useful for my daughter. It is prescribed by a geneticist. The capsule size is convenient. If necessary, you can open the capsule and take the required amount. A very useful product. The taste is normal. It gives effect very quickly and adds energy. I like the fact that it quickly helps to bring the child out of the acetonemic state.

Good stack with NMN

Good quality supplement that supports energy production and muscle recovery. The formula is gentle on the stomach thanks to its buffered form, and the capsules are easy to take. I’ve noticed better endurance and overall energy, though results can vary. Overall, a solid, clean option for cellular energy support.
