Bodybuilding Supplements - 30 Facts You Need to Know Part 1 Video Description

Older people often have poor appetites, reduced lean muscle mass and poor strength that impair mobility and quality of life. Physical deterioration from illnesses such as flu or pneumonia leaves them with little reserves, which increases the risk of death. HMB supplements might build up their reserves and improve the chances of survival when they get sick— according to a study led by Nicolaas Deutz from the Center for Translational Research in Aging and Longevity at Texas A&M University. HMB (beta-hydroxy-beta-methylbutyrate) is a breakdown product of the amino acid leucine that prevents protein breakdown and promotes muscle hypertrophy, particularly when combined with weight training. It also increases fat-free weight (mainly muscle) and decreases fat. Researchers fed a drink containing 1.5 grams of HMB twice a day or a placebo (fake HMB) to older, malnourished patients treated for heart failure, heart attack, pneumonia or lung disease. Patients given the supplement were five percent less likely to die within 90 days of hospitalization than those given a placebo. The HMB group gained more weight and showed improved nutritional status after discharge from the hospital. HMB increases protein synthesis in older adults and young athletes. Most studies show that the ideal HMB dosage is 38 milligrams per kilogram of bodyweight per day. It works best when taken close to a workout and consumed daily for two weeks prior to a competition. It is effective in young and old people, and is a safe and effective supplement for athletes and active adults. (Clinical Nutrition, 35:18e26, 2016)
