"It appears prudent for all adults to take vitamin supplements"
-The Journal of the American Medical Association (JAMA)

I don't want to replace your physician by any means, so you MIGHT NOT need to supplement IF:

1. You are in perfect health.
2. You eat a perfect diet everyday.
3. You're not a woman of child bearing age.
4. You have no digestive problems.
5. You're not a vegetarian.
6. You don't smoke.
7. You don't drink alcohol.
8. You don't have any stress.
9. You are not a child.
10. You are not a woman.
11. You are not a man.
12. You are not an adult.
13. You are not elderly.
14. You don't care about your DNA.
15. You have no concerns about your immune system.
16. You don't care about lung cancer.
17. You don't care about heart disease.
18. You don't care about prostate cancer.
19. You don't care about breast cancer.
20. You don't care about osteporosis.
21. You don't care about osteoarthritis.
22. You don't care about colon cancer.
23. You don't care at all about how smart your kids are.

3. You're a woman of child bearing age.
4. You have digestive problems.

6. You smoke.
7. You drink alcohol.
8. You have stress.
9. You are a child.
10. You are a woman.
11. You are a man.
12. You are an adult.
13. You are elderly.
14. You care about your DNA.
15. You have concern about your immune system.
16. You care about lung cancer.
17. You care about heart disease.
18. You care about prostate cancer.
19. You care about breast cancer.
