SCOTT JAGOW: More than 5 million American take glucosamine for arthritis and joint pain. Its effectiveness is a matter of debate, but a new study suggests it might work better for skin problems. From the Health Desk at WGBH, Helen Palmer reports.
ALEXA KIMBALL: They definitely lightened over the course of the study.
Dermatologist Alexa Kimball of Harvard University says three studies where none of the researchers knew who got the active ingredient showed a definite improvement in patients who used glucosamine cream.
Already welcoming the research is Proctor and Gamble.
Anti-aging skin products are a $750 million market. Proctor and Gamble is launching a new cream with glucosamine. It’ll retail at about $28 a tube.
