Been taking a Centrum every day for over 40 years until recently. When I found that they were being made in China I switched to made in USA Horbaach vitamins and supplements from Amazon. Says 313% of daily requirement of Vitamin D.Our ancestors lived into their 80s, 90s without all the **** you see pushed on TV and doctors offices. Granted they died from infections, so I'm not taking anything away from antibiotics but so long as you eat relatively healthy, you're probably doing more harm than good by ingesting that formulated crap. Helps the drug pushers bottom line though no doubt. You want to take them, knock yourself out. I'll pass.
I look, feel, and act a hell of lot younger than my parents and grandparents did at 64. I can incline bench press 275 lb, OTOH I've had high blood pressure for 20 years and The Beetus for 9 years.
My mother's father was born in 1899 and when he was 64 he was OLD. Worked in a steel mill all his life, smoked, drank, had The Beetus, retired in his early 60's when he had one leg amputated below the knee due to poor circulation. Walked with a cane always. My grandmother was also born in 1899, had The Beetus, and died from her second stroke at 68.
My mother is 89 and takes less pills than I do, lives on fast food and Diet Coke, never exercised, never drinks water, all the heart disease, strokes, and Beetus are on her side of the family yet she gets none of it and has survived cancer twice.
