Regarding Arginine, I too have reservations about using the amino acid in the off chance taking it causes an imbalance. On another forum, there was a post about maintaining proper NO (nitric oxide) levels. Lack of NO can contribute to poor circulation. Like you stated, many have used arginine for that purpose. Well, this product uses beet root powder as the primary ingredient along with hawthorne berry, L-citruline and sodium nitrate. Also has Vit C and B12 ( methyl and cyan). They state that people over 40 do not convert arginine into NO efficiently and their product takes a different approach.


It's pricey too. What's interesting is they have NO test strips so you check your levels. Wonder how many beets you would have to juice to get the same benefit.
