Don't be frightened by this article. If you stick to a proper human diet of meat(especially beef, shrimp, lobster, tuna, salmon, sardines), eggs, aged cheese, no-salt butter, cream, tree nuts, green leaf veggies then supplements usually won't be necessary. Stay away from carbohydrates like sugar, fruit, bread, pasta, potatoes, and rice. if you want to sweeten something, use the tiny Splenda tablets you can get from Amazon. The age-old con "an apple a day keeps the Doctor away" is still with us...it should be "an apple a day keeps Doctors (aka, AMA Stooges) in vacation homes and yachts".

I only supplement vitamin C and D along with Magnesium that helps speed up the body healing process as we age. D also helps with calcium uptake.

Low blood oxygen is usually caused by obesity and couch-potato-itis. Stay away from carbohydrates and get Aerobic activity...Increasing the heart rate exercises...combined with deep breathing exercises multiple time a day will solve this along with any sleep problems as well - especially as we age. A rowing machine and even a sauna are excellent. "Walking" won't bring your heart rate up enough.
