Great stamina and endurance are heavily dependent on ensuring normal, healthy blood flow. As we age, circulation begins to decline for many. Two supplements that are popular for people who want to support normal circulation are the amino acid L-arginine and the herb maca. Chronic stress sometimes includes the restriction of blood vessels.

Mason Natural Vein Erect with L-Arginine & Maca combines the amino acid L-arginine with concentrated maca in a convenient daily herbal and nutritional formula designed to support normal circulation, stamina, and endurance. L-arginine is an amino acid involved in the body's natural nitric oxide pathway, while maca has a long history of traditional use as a botanical ingredient.

Together, L-arginine and maca provide complementary support for an active lifestyle and overall wellness. This convenient combination makes it easy to incorporate these two popular ingredients into a daily nutritional routine.
