Dr. Colbert explains endothelial dysfunction, why he says the lining of your arteries makes less nitric oxide after age 50, and the daily habits he uses to support his own arteries, starting with high polyphenol olive oil.

In this clip he covers why he prefers high phenolic, high oleocanthal olive oil and how much he takes each day, how olive oil relates to oxidized LDL and blood vessel function, and how the endothelium uses nitric oxide to help arteries dilate. He also shares the nitric oxide saliva test strips he has used for years, the beetroot extract he has taken for about 20 years, how he approaches his own blood pressure, and why he says low doses of grape seed extract fall short.
