Nancy Dell: Help for knee pain; Probiotic may reduce ADHD


1. I have knee pain. I have heard a supplement called UC-II can help. Do studies support this?

About 1 in 4 people report having some chronic leg or knee pain. UC-II is a unique type of collagen made from chicken bones that may reduce inflammation and help knee pain and stiffness. Studies conflict but the most recent study published in Nutrition Journal looked at men and women with osteoarthritis of the knee.

They compared the effectiveness of UC-II to glucosamine and chondrotin and a placebo over 6 months. Those who took UC-II reported a 20 percent greater reduction in knee stiffness compared to the other supplements. UC-II is generally recognized as safe so it may be worth discussing it worth your doctor if you suffer from knee pain.

In the studies a few people reported headaches or some constipation and GI symptoms.

2. Does a probiotic reduce the risk of ADHD?

Probiotics are the healthy bacteria that live in harmony with us. A small study from Finland does suggest that the probiotic called Lactobacillus Rhamnosus may reduce ADHD and Aspergers. Researcher gave this probiotic to pregnant mothers for 4 weeks before expected delivery and 6 months after delivery to each infant – or the mother if she was breastfeeding.

Follow-up after 13 years found that none of the 40 children who got the probiotic developed ADHD or Aspergers while 17 percent of the children who did not get the probiotic developed ADHD or Aspergers. While the results are statistically significant, the researchers caution that this is preliminary research and more study is needed.

In the meantime, pregnant and breastfeeding women can eat yogurt or kefir with Lactobacillus rhamnosus. You will see it on the label of ingredients.
