Argigest Sachet contains L-Arginine. L-arginine is a chemical building block called "an amino acid." L-arginine is converted in the body into a chemical called nitric oxide. Nitric oxide causes blood vessels to open wider for improved blood flow. This could help to lower maternal blood pressure and which might increase blood flow to the placenta. L-arginine also stimulates the release of growth hormone, insulin, and other substances in the body. Argigest Sachet can be provided to pregnant women as a dietary supplement. Supplementation of Argigest Sachet during pregnancy helps to maintain healthy foeto-maternal circulation. L-arginine during pregnancy can increase the birthweight of babies who show poor growth while still in their mother's womb. Use under medical supervision.
