In a randomized-controlled clinical trial patients with mild to moderate age-related macular degeneration were placed on antioxidant supplements for a short amount of time to gauge the potential benefit to vision. The participant’s average age was 69-70 years old. They were supplemented with either inactive placebo for comparisons sake or the following combination; Lutein (10mg), Zeaxanthin (1mg), Astaxanthin (4mg), Vitamin C (180mg), Vitamin E (30mg), Zinc (22.5mg), and Copper (1mg); all taken daily for 12 months.

A new study tested the effect of regularly taking Green Tea Extract (GTE) and found that over 10 weeks, endurance exercise performance was boosted up to 24% in laboratory animals who had a 0.5% concentration of GTE added to their chow; this is about 4 cups of tea in a 165 lb person. It wasn’t the caffeine according to the researchers because the caffeine was greatly reduced in their GTE. The results "indicate that GTE is beneficial for improving endurance capacity and support the hypothesis that the stimulation of fatty acid utilization is a promising strategy for improving endurance capacity," according to the study.

In this review it was found that 10 grams a day of hydrolyzed collagen may reduce pain in osteoarthritis of the hip or knee. In fact the worse the condition, the more helpful the collagen may be. Given the importance of collagen for bone structure it was found that giving collagen along with calcitonin treatment for osteoporosis was more bone building than giving the drug alone.

Oxidative stress has recently been implicated as a cause of atrial fibrillation (AF). The aim of the present study was to evaluate the effects of N-Acetylcysteine (NAC) on postoperative AF. The population of this prospective, randomized, double-blind, placebo-controlled study consisted of 115 patients undergoing coronary artery bypass and/or valve surgery.

Scientists at the University of North Texas Health Science Center in Fort Worth are aware of the value of both EGCG from Green Tea and ibuprofen, a drug commonly prescribed for arthritic pain, in fighting prostate cancer cells. DU-145 cells are prostate cancer cells used to study how this cancer grows. When either EGCG or ibuprofen was added to the prostate cancer cells they reduced the number of cells by 25% at most.
