L-Arginine Powder, 35 oz (1,000 g)

Let me explain clearly why I recommend using more L-Citrulline than L-Arginine — even though some supplements do the opposite. The science behind it: L-Citrulline and L-Arginine both lead to nitric oxide (NO) production → better blood flow and muscle pump. BUT: L-Arginine: Is poorly absorbed in the intestines. A lot of it gets broken down by the liver before reaching your bloodstream. So, even if you take 6 g of Arginine, you may only get 2 g of useful effect. L-Citrulline: Absorbs easily and bypasses the liver. It is converted into Arginine inside your body — but more efficiently and stably. So taking 6 g of Citrulline leads to higher blood Arginine levels than taking 6 g of Arginine itself. That’s why clinical studies and professional formulations usually recommend: More Citrulline than Arginine — typically 2:1 ratio Example from real research: One study found that 6 g Citrulline raised nitric oxide more than 6 g Arginine. Taking Citrulline + Arginine together in a 2:1 ratio improves absorption and boosts pump even more. Summary: L-Citrulline — Strong, lasting NO booster — Higher dose. L-Arginine — Short-term NO boost — Lower dose. Best Combo — Citrulline:Arginine = 2:1 — More effective and better tolerated

Great quality arginine powder. The tast is bad, like all arginine powders, but mixed with food is easy to take.

I started taking L-arginine to improve my endometrial thickness. Don't know if it's because of L-aginini, or because of other lifestyle changes combined, but my period is better now, and I assume my endometrial thickness is also better.

This powder dissolves quickly and easily in my water and easy to swallow

It has effect on my "pump" during weightlifting—my muscles feel fuller and my physical stamina stays high from the first rep to the last.

bought this for my son. He puts it in his smoothies. l-arginine is an important amino acid to take. clean ingredient. doesnt taste anything. a great workout companion. the price is alright. an essential supplement.

I mix this powder in a glass of water, and it's ok to drink, not disgusting. only one ingredient. it helps to lower high blood pressure.

I like that this product in powder. Very convenient to give it to kids. Recommend

This product is easy to use, and a good value. I needed arginine as part of the amino acid blend my doctor wants me to take to address deficiency and support my gut. I recommend this one if you're looking for arginine. A little scoop mixes easily into my amino blends that I put in almond milk.

It works as intended, mixing with an apple juice, bought for family as well!
