Looking after your brain, brain food, can we drink coffee (please say yes!), low Vitamin D, HRV and the brain. With Dr. Dale Bredesen #409

One of my favourite Zestology guests is back. Neurologist Dale Bredesen, M.D., author of the New York Times bestselling book The End of Alzheimer's, had the Number 1 book in the world for 2 days, (surpassing Hillary and Oprah). Here are some of his big themes. Fasting: 14 to 16 hours? What's good? Do you allow coffee in that time? Saturated fats Good fats and histamine intolerance. Omega 3s. What supplements? Resveratrol. Is it really that good? Heart Rate Variability Oxygen saturation   THIS SHOW IS BROUGHT TO YOU BY: BiOptimizers — Four out of five Americans are magnesium deficient, and almost everyone is at suboptimal levels. That's a big problem because magnesium is involved in more than 600 biochemical reactions in your body. Now here's what most people DON'T know: taking just any magnesium supplement won't solve your problem because most supplements use the cheapest kinds that your body can't use or absorb. That's why I exclusively recommend Magnesium Breakthrough. It's the only full-spectrum magnesium supplement with seven unique forms of magnesium that your body can actually use and absorb. When you get all seven critical forms of magnesium, pretty much every function in your body gets upgraded. From your brain to your sleep, pain, inflammation and less stress. Here comes the best part: the makers of Magnesium Breakthrough - BiOptimizers - are having an incredible Black Friday special offer from November 21st to 29th. You can get - not only Magnesium Breakthrough - but all of BiOptimizers best in class products with 25% off. (In the UK, the discount is 10% not 25%)
