Swanson L-Arginine & L-Ornithine – 100 caps

L-Arginine & L-Ornithine is a capsule-format amino acid supplement combining two free-form amino acids in a two-to-one ratio. Each capsule delivers 500 mg of L-Arginine Base alongside 250 mg of L-Ornithine (as L-Ornithine HCl), and the pack contains 100 capsules in total. Both amino acids occur naturally in the body, and together they are a well-established pairing within the sports nutrition and bodybuilding communities.

L-Arginine is a semi-essential amino acid that plays a role in the body’s production of nitric oxide, a compound of interest to many athletes and those who train regularly. L-Ornithine is itself an amino acid that the body can convert to arginine, making the two a complementary combination. The free-form delivery means the amino acids require no further breakdown before absorption.

These capsules are particularly well suited to strength athletes, bodybuilders, and those following structured training programmes who want a straightforward way to include this classic amino acid pairing in their nutritional routine.
