Taurine is a conditional amino acid, meaning it can be synthesized by the human body but is also obtained from dietary sources.

Ascorbic Acid

Ascorbic Acid, widely known as Vitamin C, is a naturally occurring organic compound with potent antioxidant properties. Appearing as a white to light yellow crystalline powder, it is highly water-soluble and plays a critical role in human health, food preservation, and industrial manufacturing.

Inositol

Inositol, historically referred to as Vitamin B8, is a naturally occurring sugar alcohol and a crucial component of cell membranes. It plays a vital role in cellular signaling, lipid metabolism, and neurotransmitter regulation. Appearing as a white, odorless crystalline powder with a mildly sweet taste, Inositol is highly stable and water-soluble.

L-5-Methylfolate Calcium

L-5-Methylfolate Calcium is the calcium salt form of L-5-methyltetrahydrofolate, which is the predominant, biologically active form of folate found in nature. Appearing as a white to light yellowish crystalline powder, it represents the most advanced generation of folate supplementation.Unlike synthetic folic acid, L-5-Methylfolate Calcium does not require complex enzymatic conversion in the human body. It is absorbed directly by the cells, making it the premier choice for pharmaceuticals, high-end nutraceuticals, and functional foods.
