Features:
Vitamin K2 (menaquinone)
Menaquinone-4 (MK-4), a subtype of vitamin K2 Helps blood clot, calcium metabolise and heart health.
Bone health: Vitamin K2 helps to regulate calcium levels in the body, which can help to prevent conditions such as osteoporosis and fractures.
Vitamin K2 has been studied for its potential role in cancer prevention and treatment. Some of the key findings include:
-Shown to inhibit the growth of cancer cells, including those found in leukemia, lung cancer, and prostate cancer.
-Shown to induce apoptosis (cell death) in cancer cells, which can help to prevent the spread of cancer.
-Shown to have anti-angiogenic effects, which means it can help to prevent the formation of new blood vessels that feed cancer cells.
-Synergistic effects with other nutrients, such as vitamin D and calcium, to enhance its anti-cancer effects.

Vitamin K2 exists in several forms known as menaquinones, with MK-4 and MK-7 being the most studied. MK-4 is often used in Japan for therapeutic purposes, whereas MK-7 (derived from bacterial fermentation) is widely available as a supplement in Western countries.
For bone and cardiovascular health—and by extension, exploring potential anticancer benefits—doses for MK-7 commonly range from 90 to 200 micrograms per day.
