Description
NOW Foods Arginine & Ornithine – Amino Acid Combination Capsules
NOW Foods Arginine & Ornithine combines the amino acids L-arginine and L-ornithine in vegetable capsules. Both are part of the body’s urea cycle, where ornithine and arginine are converted into one another, which is why they are often supplemented together. Arginine is also the amino acid the body uses to make nitric oxide. This arginine and ornithine supplement is a long-standing favourite with strength athletes.
Key Benefits
- Two amino acids together – L-arginine and L-ornithine in each capsule.
- Urea cycle partners – ornithine and arginine are closely linked in the body’s metabolism.
- Vegetable capsules – vcaps rather than gelatin shells.
- Stim-free – can be taken morning or evening.
- Two sizes – choose the bottle that suits your routine.
Who Is It For?
Ideal for bodybuilders, strength athletes and gym-goers who like classic amino acid stacks, and anyone who prefers a capsule that combines two amino acids rather than buying them separately and taking extra pills.
Flavours & Sizes
Available in two sizes: 100 vcaps and 250 vcaps.
FAQs
When should I take arginine and ornithine?
Many people take it on an empty stomach, either before training or before bed. Check the label on your pack for the recommended serving.
Is it the same as arginine and citrulline?
No. Ornithine and citrulline are different amino acids, although both are linked to arginine in the body’s urea cycle.
