re: Marijuana research for Alzheimer's cure stymied.

Make sure you are getting enough vitamin K2 in your diet. Vitamin K can help to prevent Alzheimer’s.

The study talks about vitamin K however it's vitamin K2 that people lack as they get older that leads to the misallocation of calcium. You can make vitamin K2 in your gut by eating food with sufficient vitamin K, however K will not convert to K2 without the proper flora in your gut.

Vitamin D3 gets the calcium from your gut to your blood stream. Vitamin K2 gets the calcium from your blood stream to your bones and teeth. With insufficient K2 your bones can become lower in density over time (osteopenia), arteries become calcified, nerves become calcified among other calcium misallocatoin problems.
