Creatine is the fuel that powers your muscles. Your body produces creatine naturally, storing it in your muscles and drawing on it when needed to create energy—during exercise for example. Stores of creatine are rapidly depleted during exercise however, leading to fatigue. By supplementing with creatine, you can increase the amount your body has available, which can help you exercise longer. In this way, creatine has a direct impact on building and maintaining muscle strength. In many dozens of studies, creatine has been shown safe and effective for boosting muscle strength when combined with exercise such as resistance training.*  Read more about creatine >


Bone health supplements typically come as calcium carbonate or calcium citrate. Calcium citrate was selected because it is more easily absorbed with or without food. Dr. Ni's OC2 provides 600mg of calcium citrate (60% RDV) per serving, an appropriate amount for bone health that leaves room for calcium to be consumed as part of a normal diet, to avoid health problems sometimes associated with excessive calcium intake.* 


Vitamin D helps your body more easily absorb calcium. Most studies agree that D3 (cholecalciferol) is more readily absorbed than D2, and therefore performs better for calcium absorption.*


Magnesium is an important element for establishing good structure in new bone growth. It also helps with the absorption of calcium by increasing the activity of vitamin D3.*
