Creatine 7-Day Booster is a special creatine supplement designed for those wanting to take full advantage of the muscle-building power of creatine as fast as possible. Studies show that maximum gains in muscle strength are achieved by taking as much as 21 grams of creatine per day, for 7 days. In scientific terminology, this is called the "loading dose": you take that amount to quickly build up the body's creatine stores. One week is all that's needed. Following the "loading dose" phase, 3 to 5 grams a day for maintenance is effective enough to enjoy creatine's benefits for muscles, energy, brain function, endurance and more.* It's important to know that the loading dose is not just for body-builders and younger athletes. The creatine research has found that it works for older adults, including men and women.* Recent studies have found that older adults realize gains in muscle mass and strength with creatine supplementation. A meta-analysis of randomized placebo-controlled trials found that older people taking creatine along with a program of resistance training achieve better gains in total body mass and fat free mass, along with improvements in chest press and leg press performance, than they do with exercise alone. Another study tested the effect of creatine taken by older adults either before or after a workout. Either way, creatine produced increases in lean body mass, muscle thickness and body strength over a 12-week period.* Older women also do well on creatine supplementation. A group of older women engaged in a 12-week resistance training program with or without creatine supplements. Just as it did in men, creatine produced gains in fat free mass, muscle mass and strength tests.
