Many people will think that building muscle and taking supplements would go together. when people decide to focus on something like building muscle and looking better, they always go for it and become more susceptible to any product on the market that can help them toward their goals. Sometimes there is also the fact that physicians and Sports Medicine will “Mix one part fact with several parts ignorance; season with advertising, sprinkle on a need, and you have a recipe for protein supplements”. But are supplements really necessary? Provided you have a proper diet, probably not.
First, how do we actually build muscle? By physically exerting the muscles, we break down and damage the muscle fibers. The protein we consume is then broken down by the body to produce amino acids, which are transported to the muscle fiber to rebuild and over time increase muscle size. If in your diet you consume enough protein to rebuild those muscles properly, supplements will not be necessary.
Then the question becomes how much protein must be consumed in the diet in order to keep up with the muscle rebuilding process? For high-level athletes who are doing vigorous training, more will be needed than the average person just trying to keep fit and look good, but short of body-building.
