Creatine is a great supplement for both building muscle, and toning down/losing fat*. What creatine does, is it causes your muscle cells to produce ATP. Creatine is a 100% natural compound, and is naturally occurring in our bodies, and can also be found in certain foods (salmon, beef, herring, tuna…). It’s simply great for bodybuilding, because it helps with gaining lean muscle mass, and keeping high energy levels during intense workouts. Personally, I’ve been taking creatine for a little over a year now. I’ve experimented with several different brands and types of creatine, (yes, there is many many different forms of creatine) and I’ve found great results from it.
I would recommend it if you:
-are working out on a regular basis, (3+ times a week)
-having trouble gaining/losing weight
-having trouble keeping high energy levels during your workouts
-have been seriously working out for over a year

*fat loss is not a direct benefit from creatine. the creatine will give you more energy and endurance during the workout, which could lead to fat loss.
