L-Citrulline, Free Form Amino Acid, 5.3 oz (150 g)

Perfect on its own! No flavor to me, and disappears into whatever I put it into. I chose to go this route to get my NO levels up, instead of taking NO supplements, because the body uses this to more efficiently convert to NO. I'm paranoid of new supplements, so I went slow, which in hindsight, there was no reason to. I take about 2 small scoops daily. So far so good...I think!

Works very good I take two scoops before a workout and carries me through an hour of weightlifting.

Quality product

I am 63 and I can feel a difference , more pumped feeling in the muscles, when using this L-Citrulline. I mix with water and there is no taste issues. I use other Nutra-Bio products and like them. Looking at the question and answers section and other reviews, I want to point out that Nutra-Bio packages this product in the USA, but the label says "ingredients sourced worldwide". This usually means from China but they want to avoid saying that considering the the common poor quality and safety issues with products sourced from there.

Love these, really freaking fantastic for the price as well

Really great product. I was unable to take most pre-workout formulas due to the caffeine and magnesium added to them so this is a great substitute for those that cannot handle the side effects of those products. Delivery was fast and this product really helps with those that like to work out hard.

I’ve tried other brands and for some reason this product made me itch all over and there’s no returns.

Simply the best! Made in USA first off; not China like most supplements these days. Secondly, no fillers, magnesium stearate, dyes, artificial sweeteners, nothing but pure Citrulline. And best price for the amount they give you. Nutrabio has become my goto for a lot of the supplements I take.
