Magnesium
Magnesium
Magnesium is an essential mineral involved in over 300 enzymatic reactions in the human body. It plays vital roles in protein synthesis, muscle and nerve function, blood glucose control, and energy metabolism. This mineral is particularly important for cardiovascular health, bone formation, and stress management.
Vitamin D
Cholecalciferol
Vitamin D is an essential fat-soluble vitamin that functions as a hormone in the body. It plays crucial roles in calcium absorption, bone health, immune function, and cellular growth regulation. Often called the "sunshine vitamin," it can be synthesized by the skin when exposed to UVB radiation.
Multivitamin
A comprehensive supplement containing multiple vitamins and minerals to support overall health and fill nutritional gaps.
Collagen (Hydrolyzed)
Collagen Types I & III
The most abundant protein in the body, providing structure to skin, bones, tendons, and connective tissue. Hydrolyzed collagen (collagen peptides) is broken down for optimal absorption. Supports skin elasticity, joint health, bone density, and gut lining integrity.
Omega-3 Fatty Acids
Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA)
Omega-3 fatty acids are essential polyunsaturated fats that the body cannot produce on its own. The two most important types are EPA and DHA, primarily found in fatty fish and fish oil supplements. These fats are crucial for brain function, heart health, and inflammation regulation.
Melatonin
N-acetyl-5-methoxytryptamine
Natural hormone that regulates sleep-wake cycles
Creatine Monohydrate
Creatine Monohydrate
Creatine is naturally occurring compound that enhances ATP production, supporting muscle strength, power output, and cognitive function. One of the most researched supplements.
Vitamin C
Ascorbic acid
Vitamin C is a water-soluble vitamin and powerful antioxidant essential for immune function, collagen synthesis, and iron absorption. Unlike most animals, humans cannot produce vitamin C and must obtain it from dietary sources or supplements.
