Creatine a.k.a. ”the most researched” bodybuilding supplement has been promoted heavily over the last few decades. Many consider it a must for natural bodybuilders.
Is the hype backed up by real results?
Function: The main function of creatine is to facilitate the recycling of Adenosine Triphosphate (ATP).
ATP is known as “nature’s energizer” and is produced by almost all living things. ATP is essentially the “spark that lights the fire”. It triggers cellular metabolism. Without ATP cells have no energy to repair, reproduce and function.
Creatine is an amino acid first synthesized in the liver. 95% of it is transported to the skeletal muscle. When the need for energy is high, ATP is rapidly re-synthesized with the use of phosphocreatine (PCr) through a reversible reaction with the enzyme creatine kinase (CK). Since creatine increases the muscles’ PCr stores, the body’s ability to re-synthesized ATP improves as well. Consequently, muscle endurance goes higher.
Creatine is not an essential nutrient. The body can produce creatine from the amino acids L-arginine, glycine, and L-methionine. Protein sources rich in these amino acids provide all the creatine needed for good health. Supplements never put that on the label, do they?
Experts believe that since creatine supplementation increases energy, one should be able to do more repetitions. In return, more reps (volume) are supposed to stimulate more muscle growth. However, it’s hard to tell if those extra reps are not just a placebo effect. Moreover, how are a few reps supposed to change your physique anyway? Besides, you can just do another set and reach the same overall lifting tonnage.
Excessive amounts of creatine has been used by many lifters. There are people who have been using the stuff for years and years with zero results. This is not a surprise because supplementation plays a very small portion in the process of getting bigger. Nutrition and training are more important.
The big believers in creatine are easy to spot in every gym. They are the smallest guys with the thinnest wallets.
Everything about creatine can be summarized in a few lines:
- Creatine is not an effective muscle builder. Most of its effect is based on placebo and wishful thinking of the highest order.
- Creatine is not an effective strength enhancer – strength and endurance are two different things. Strength coaches consider creatine supplementation unimportant when you perform low repetition sets.
- Creatine promotes water retention and decreases your muscular definition.
- Creatine often causes diarrhea.
- Creatine can cause kidney problems. The risk is low but it’s not zero. People who are more likely to be affected are patients with pre-existing kidney problems.
- Some people don’t feel anything from creatine. I am one of them. It does nothing for me.
- You don’t need creatine to hit the natty limits.
Turn off the TV, read more, love more and don’t trust the bodybuilding propaganda.
