Most Wanted Supplements:

Are They Cancer Killers or Frauds? What You Need to Know, con't

Suspect: Turmeric

Charge: Turmeric, a curry spice, has anti-inflammatory properties and contains an antioxidant called curcumin. In very early basic laboratory studies, curcumin has been shown to stop the spread of melanoma cells. However, researchers do not know whether curcumin has any anticancer effects in humans.

Verdict: A recent study showed turmeric may interfere with chemotherapy for breast cancer, so avoid turmeric during chemo. Turmeric supplements also may worsen gallbladder problems or slow blood clotting. If you have finished treatment and want to learn how to use turmeric as a spice, try our recipes featuring tumeric.

Suspect: Vitamin D

Charge: Vitamin D to reduced cancer risk. Vitamin D helps control cell growth and holds promise for cancer prevention.

Verdict: Research hasn't determined what dose of Vitamin D is effective -- and safe -- for cancer prevention.

In the meantime, eat oily fish along with milk and fortified cereals. If you have darker skin or are older than 50, get your vitamin D from limited sun exposure or ask your doctor if you require a supplement. The U.S. Food & Drug Administration recommends 400 IU for those 51 to 70 years old and 600 IU for those 71 and older. Continue to wear sunscreen; even though our bodies manufacture vitamin D as a result of sun exposure, it isn't worth the skin cancer risk.
