  • Maximum-Strength L-Arginine Alpha-Ketoglutarate



  • Supports physical energy and faster muscle recovery



  • Supports healthy blood flow for optimal delivery of oxygen and nutrients to cells


Alpha-ketoglutarate, an amino acid compound used for energy metabolism, accelerates absorption of L-arginine. You'll enjoy steadier energy levels with the more efficient exchange of cell nutrients and wastes and speedier delivery of oxygen to the tissues. Supplementing with Arginine AKG also promotes faster muscle recovery after exercise and may support greater gains in anaerobic power when combined with a resistance training program.

Rated 5 out of 5 by Strong! I use this product daily before my workouts. September 17, 2013
Rated 5 out of 5 by I use a scoop of Swanson's awesome AKG Arginine Powder in my morning Whey Protein Cocktail (also containing Spirulina and other Aminos) with excellent results for muscle building, strength, and tone. Improvement is quite noticeable! I've used Arginine with Ornithine, Lysine, Glutamine, and Glycine to my total satisfaction since the 1970s. In the afternoon or evening, I'm not making another one of my Super Protein Cocktails, so I find it convenient and productive to take about 3 of these 1,000 mg. Arginine AKG capsules. I always take 4 of the 500 mg. L-Ornithine capsules with my Arginine. I also find it very productive to take 3 or 4 of these 1,000 mg. Arginine AKG caps, along with my 4 L-Ornithine 500 mg. caps, IMMEDIATELY AFTER working out. Give that a try. . . . Try it; you'll like it. Depending on what my routine was during the day, I may take this same combination at bedtime for muscle regeneration while I sleep. You can read a lot about that technique. Whatever your purpose or dosage, and don't forget heart health, it is my opinion that you will find this Swanson Arginine AKG 1,000 mg. capsule an Excellent and Productive Product. August 14, 2013
Rated 5 out of 5 by Feeling Great I feel revitalized and have a new zip in my step since taking Arginine AKG. I would recommend it to anyone. July 29, 2013

Rated 5 out of 5 by Great product I take three, three times a day and I feel great. I notice my vascularity really comes out when I take it, compared to the days I don't. June 13, 2013
Rated 5 out of 5 by Helps Muscles and Love Life I was surprised when I tried this product for muscle recovery to find out that it also helps with my love life. My fiance noticed it immediately by the way she responded to what it was doing to me. I never would have suspected that it would help make things better in that area too. June 9, 2013
