Nitric Oxide Supplement including L-Arginine and L-Citrulline, Nitric Oxide Booster for blood flow, muscle growth, and energy. Essential Amino Acids for physical training support, 60 veggie capsules. Why take Nitric Oxide Flow? It has 2 main ingredients and 2 different forms of L-Arginine and L-Citrulline. L- Arginine Alpha Ketoglutarate, L- Arginine HCI, L- Citrulline, and L-Citrulline Malate. We have a 2:1 ratio of L-Arginine to L-Citrulline. L- Arginine converts into Nitric Oxide in the Body, and L- Citrulline is converted into L-Arginine which is then converted into Nitric Oxide. L-Arginine is more of a fast acting boost of nitric oxide production as L-Citrulline is converted when the body needs to use it. So with our 2:1 ratio not only do you get the instant effect, but you also keep your nitric oxide levels up as your body will use the L-Citrulline as needed to convert into Nitric Oxide. L- Arginine Alpha Ketoglutarate- Is naturally found in the body and foods. It is a salt from the amino acid L-Arginine, which is a building block of protein. L- Arginine is converted to Nitric Oxide in the body. Research has shown that L-Arginine Alpha Ketoglutarate can improve athletic performance, increase blood flow and support normal blood pressure levels. L- Arginine HCL- Is naturally found in the body. L- Arginine Hydrochloride is the Hydrochloride salt from L-Arginine. HCL is just another form of L-Arginine which all turns into Nitric Oxide by the body. L-Citrulline- L-Citrulline is a natural amino acid found in the body. Research shows that Citrulline will lead to more consistent arginine levels. Citrulline is used as needed by the body and it is also better absorbed then Arginine. L-Citrulline is converted to Arginine which is then converted to Nitric Oxide. L-Citrulline Malate- L-Citrulline malate plays a role in the TCA cycle.
