Felix explores the anti-cancer properties of *Vitamin K2.* Here are the main points: Healthy cells have a self-destruct mechanism called *apoptosis.* Cancer cells survive by silencing this program so they can keep dividing indefinitely. Research shows that exposing certain cancer cells (like leukemia, breast, and liver cancer cells) to Vitamin K2 can "switch back on" this self-destruct signal. Vitamin K2 belongs to a group of molecules called *quinones,* which are involved in cellular energy production. Cancer cells grow rapidly and have unstable energy systems, but vitamin K2 interferes with mitochondrial function specifically in cancer cells (but not healthy ones), disrupting their energy production. When this instability reaches a tipping point, the cancer cell triggers its shutdown sequence. Felix highlights that liver cancer is one of the most well-studied areas for Vitamin K2. A recent study involving human patients confirmed that K2 supplementation significantly reduced disease recurrence and decreased mortality over 1–3 years. There are two common forms of K2: *MK-4* and *MK-7.* While MK-7 is popular for bone health, some research suggests *MK-4 may be more effective for anti-cancer purposes.*

Vitamin K2 (mk-7) is a seriously powerful beast. I remember reading a study about one of the main reasons that Japanese people lived such long, healthy lives, with little cardiovascular disease and lower cancer morbidity and mortality rates compared to other groups of people. Their secret? Japanese eat a fermented soybean breakfast called "Natto", which researchers have discovered is super rich in vitamin K2 and an enzyme called nattokinase, which acts similar to a blood thinner and provides cardiovascular benefits. The combination of vitamin k2 and nattokinase provides extraordinary health benefits, from cardiovascular health and artery health to reduced cancer rates. I don't like the taste of Natto, so instead I supplement daily with vitamin k2 (mk-7) and nattokinase (4000 FU) to replicate the Japanese Natto health benefits.

Life Extension has a Mega Vitamin k2 that is mk4 and in high dose mg instead of tiny dose micrograms.

So many people hit the comments before even listening the video: it's specifically MK4, not K2 Mk7.

I recommend a different approach: Our body can transform K1 into K2 MK4 via UBIAD1. In order to increase the MK4 concentration in the body in all tissue, I do K1 flooding via kale, broccoli, parsly, Brussel sprouts, spinach and so on. In order to get enough K1 into all tissue you need to satisfy the liver. So I try to eat in each meal K1 rich foods and probably reach 2 to 3 mg K1 overall, sometimes a bit more even. Dietary MK4 in itself most likely won’t make it to all tissue and will be absorbed instantly. The UBIAD1 needs some time to be on track, but it’s the most natural approach and apparently the strongest one to raise MK4 concentration in all tissue. Key elements: high quantity of K1, greens should be steamed and consumed with fat. No need to supplement MK4, eating grass fed animal products (butter, meat and such) is enough to get it 😊

It's probably more so that people with cancer may be deficient in minerals which would signal the cells in their body to trigger apoptosis and those cells turn into cancerous cells instead.
