Creatine is one of the most researched and important sports supplements today. It has become a must for athletes wanting to increase workout intensity while delaying the onset of fatigue. Research has shown that supplementing with creatine can boost muscle size, strength and endurance, improve athletic performance, and speed muscle recovery. Saturating your muscles with creatine improves your body’s ability to quickly replenish and recycle ATP, which increases muscle energy and delays muscle fatigue. Studies show that when athletes supplement with creatine while weight training, they can quickly gain lean body mass and strength.
