What is Alpha Ketoglutarate?

Alpha ketoglutarate (AKG) is a precursor to glutamine and glutamate, which makes it a central fuel in various metabolic processes. Combined with ornithine, and amino acid, alpha ketoglutarate forms a salt (ornithine alpha ketoglutarate, or OKG) that is commonly taken by bodybuilders and athletes to help with muscle growth, endurance, and recovery.

Alpha ketoglutarate is also available with arginine as L-arginine alpha ketoglutarate (AAKG).

Great Product

I am not a body builder. I'm 82 yr old and have been using this product every morning in my drink of Honey and Vinegar plus apple juice. I have tasted the powder and it has a pleasant taste. I also take a regimen of vitamins, minerals and herbs every day. I am trying to maintain the body and health that I have as long as I can.

Bulk Supplements Delivers!

I wanted some OKG which is hard to find locally retail. So i ordered and the product was delivered quickly, though when I went to find the product at the location where the carrier said it was dropped off, no such package. I asked neighbors and nothing. I asked my family and they never saw a package either. So I called Bulk Supplements figuring I'd get the run-around, but no. They simply said they would send me a replacement pack. We reconfirmed my address and a few days later the package did indeed come. I figure the first one was stolen off my front porch and I give credit to Bulk Supplements for working so quickly to get me a replacement without any hassles. I will certainly buy from them again when looking to buy any future bulk supplements that I don't carry in the vitamin shop I work in here in Chicago. Thanks for the great customer service and thanks for a great product. I tried it today for the first time and it tasted and worked great.

OKG powder

The price is better than most places. The shipping was immediate, which in my experience is better than 90% of other online supplement retailers.

L-Ornithine a-ketoglutarate OKG - 100g Pure Powder

I am a very active 80 year old. I take a lot of supplements. I take OKG powder mixed with apple and grape juice, honey and vinegar. I believe this is helping to hold back muscle loss and help me stay strong. I believe the OKG is a tremendous help in this effort.

L-Ornithine a-ketoglutarate OKG

I just returned from vacation. I worked 4 gm into my schedule on an empty stomach. As per usual BS delivered the top quality powder. Reduced blood ammonia with L-ornithine alpha-ketaglutarate aided longer workouts and quicker recovery with maybe a tiny edge in growth hormone. A great value.
