Nitric Oxide

Nitric oxide dilates the blood vessels, which improves the blood circulation to the muscles (and all the organs in general). This increases the nutrient supply where they are needed the most, enhancing the muscle growth, strength and endurance.

Nitric oxide, also known as nitrogen monoxide (NO), is a gas that is endogenously produced in very small amounts in our bodies thanks to the amino acid L-arginine. One of its most outstanding functions is its ability to stimulate the dilation of the blood vessels.

What are the nitric oxide stimulators?

They are a type of supplement with ingredients that are capable of activating the mechanisms in charge of stimulating the NO, which enhances the vascularization.

The two main ingredients that are used for this purpose are l-arginine and l-citrulline.

L-arginine is a non-essential amino acid (our bodies can synthesize it) and it is present in many proteins from our daily diet. Once it is absorbed by the digestive tract, arginine travels through the blood to the tissues or organs that need it.

L-arginine stimulates the nitric oxide synthesis once it enters the cells through the nitric oxide synthase ecytoplasmic enzyme (NO Synthase).

L-arginine and L-citrulline to increase the nitric oxide

New pre-workout products with l-arginine are starting to include citrulline malate as well, since this ingredient has the ability to endogenously increase the blood plasma arginine levels.

How to use nitric oxide stimulators

L-arginine and L-citrulline supplementation increases the nitric oxide production. However, nitric oxide cannot be stored in the body, which means that these amino acids have to be consumed daily and before exercise.

We should keep in mind that, since it is a molecule that is synthesized by the body, we need to stimulate the need to produce nitric oxide. Otherwise, the endogenous nitric oxide production will drop.

Our body is a machine that produces only what it needs. This is why, as long as there is enough NO available, it will not produce it.

This is why it is important to cycle our supplements. For instance, take nitric oxide stimulators for two or three months, then take a break for two or three months before using a different supplement. Nitric Oxide enhancers are products that should be used with caution and always being aware of their effects.

Where can I buy nitric oxide?

In HSN, we have nitric oxide stimulators and also combinations with creatine and stimulants. You can purchase the nitric oxide products that you need and they will be ready for immediate dispatch.
