SMARTER is Enhanced with Premium Kale Powder. Kale is a highly nutritious vegetable known for its many phytochemicals. It is one of the best sources of Vitamin K. It is also a great source for Vitamin C and manganese, which is important for skin health. K2 MK-7 vs K1 & K2 MK-4 - K2 MK-7 has a far longer half-life compared with K1. K1 quickly disappears from circulation (half-life = 1–2 hours). By contrast, MK-7 has a very long half-life (in the range of 2–3 days). This difference means that people given equivalent amounts of K1 and MK-7 have considerably higher serum concentrations of MK-7. As a result, MK-7 is far more bioactively accessible. K2 MK-4 also has a very short half-life, (also measured in hours rather than days). Smarter Vitamin K2 MK-7 activates proteins that play a role in calcium metabolism and heart health. One of its most important functions is to regulate calcium deposition. SMARTER is Made with K2VITAL - A key ingredient for optimal health, Vitamin K2 MK-7 K2VITAL menaquinone ensures calcium reaches the bone mass making it an essential vitamin to support bone and cardiovascular health.
