Leírás

Alkalmazás

• Improvement in Dental Health Products: Studies have shown that L-Arginine monohydrochloride enhances the bioavailability of fluoride in dental care products, promoting better oral health (Bijle et al., 2020).

Biokémiai/fiziológiai hatások

Substrate of nitric oxide synthase, which is converted to citrulline and nitric oxide (NO). Induces insulin release by a nitric oxide-dependent mechanism.
