Arginine + Ornithine 4000

Our Arginine + Ornithine 4000 capsules provide a full 2500 mg of valuable L-arginine and 1500 mg of pure L-ornithine per serving to provide your body with everything it needs during times of intense training.
In stressful situations (e.g. training, illness), the body's own production of L-arginine may not be sufficient. For athletes and physically active people, supplementing with the amino acid may be useful. L-ornithine is a non-proteinogenic amino acid and an L-arginine metabolite (metabolic product) that plays an important role in the urea cycle. L-ornithine is also a precursor of the amino acid L-citrulline. L-citrulline is in turn able to increase L-arginine levels in the blood.
Because of its function as a precursor to the vasodilating nitric oxide, many athletes like to take L-arginine before training. Because L-ornithine can be converted into L-citrulline, it works in synergy with L-arginine.

Ambitious athletes do not want to leave anything to chance and focus on providing their bodies with all the nutrients they need to optimize their performance.
Both amino acids perform important functions in our body. Since L-arginine is a semi-essential amino acid, supplementation may be useful in times of increased demand (e.g. stress, including exercise and infectious diseases). The combination with L-ornithine is beneficial because L-ornithine is a metabolite of L-arginine and can indirectly increase L-arginine levels in the blood.

Most athletes take Arginine + Ornithine 4000 before training to provide their body with a sufficient amount of the semi-essential amino acid L-arginine and its metabolite L-ornithine during training.
In times of increased need, we recommend taking it in the evening on non-training days, preferably on an empty stomach.
