Many dietitians are recommending a supplement of 5,000 milligrams of creatine a day for weightlifters. Creatine will help you improve your workout by providing more fuel and energy for your body, meaning it can help you sprint or lift for longer periods of time. In order to get the amount of creatine required to help you hit long-term goals, you would have to eat an unattainable amount of meat. The average amount required to reach this is around eight times as much meat as the average person normally eats. While there haven’t been many trials to determine which brand or form of creatine is the best, look for one that is “Certified for Sport” by the NSF International or other third-party credentials.
