People looking for drastic/quick improvements often think supplements are
the magic cure all for their desires.
For example – looking at a fitness magazine one can’t help but notice
advertisements for “breakthrough” products that will help you “see results
fast”
What most don’t know – often supplement brands are owned by the
magazine you are looking at or vice versa! (Ex: MuscleLink supplements
are owned by Ironman magazine, Flex magazine is owned by Weider
supplements)
You CAN build muscle without taking supplements by eating a healthy
diet rich in nutrients (in particular protein)
Supplements are meant as a compliment to a regular healthy diet and in
some cases are more convenient methods of obtaining crucial nutrients for
healthy active individuals.
