After a long day cragging, my tendons creak, so I was eager to try NUTRIEX SPORT ($55.50 for a month’s supply, nutriex.com), a supplement engineered for athletes by researchers in the fi elds of nutrition, bioengineering, preventive cardiology, cancer prevention, gastroenterology, orthopedics, and ophthalmology. The result of all this brainpower is easy-to-digest capsules with therapeutic levels of the proven cartilage protectors glucosamine and chondroitin. You also get key vitamins, minerals, and plant extracts to speed recovery, optimize athletic performance, and enhance the immune system. Nutriex Sport vanquished that worrisome elbow soreness and allowed me to recover noticeably faster after hefty workouts.
