NOW Sports Arginine & Citrulline is an arginine citrulline capsule with 500 mg L-arginine and 250 mg L-citrulline in each vegetable capsule. At NOW’s suggested 1 capsule twice a day, the bottle of 120 lasts 60 days and gives 1,000 mg arginine and 500 mg citrulline daily. Both are amino acids found in foods such as meat, nuts and watermelon. It has no caffeine, so it suits lifters who want a stimulant-free amino acid to take alongside training or on its own.

Arginine & Citrulline questions
How much arginine and citrulline is in each capsule?
Each veg capsule has 500 mg L-arginine and 250 mg L-citrulline, both free-form. At NOW’s suggested 2 capsules a day that is 1,000 mg arginine and 500 mg citrulline.
How do I take it?
NOW’s current label says 1 capsule twice a day. On training days you can take one of them 30 to 60 minutes before your workout. Older labels gave higher doses; follow the directions printed on your own bottle.
Is it a pre-workout?
Not in the usual sense. It has no caffeine or other stimulants, so it won’t give you an energy kick and you can take it in the evening. Many lifters take it alongside their regular pre-workout or on its own on stimulant-free days.
Is it suitable for vegans?
Yes. NOW lists it as vegan, kosher, halal and non-GMO, in a vegetable capsule. It isn’t made with wheat, gluten, soy, milk, egg, fish or shellfish ingredients, though the factory handles them.
Who should not use it?
It is for adults only. Don’t use it if you’ve had a heart attack. Ask your doctor first if you take heart medication, nitrates, blood thinners or sildenafil-type medication, or if you have glaucoma or recurring cold sores. Food supplements don’t replace a varied diet. If you’re pregnant, breastfeeding, under 18, taking medication or have a medical condition, ask your doctor first.
