Do you take supplements? This could be anything from an omega-3 or a multi-vitamin to taking a creatine, beta alanine or a protein supplement.I'm always curious about the people who don't take supplements? I try and think of all the reasons someone might say 'no thanks, not for me'. And really this comes down to people who are at the peak of their health or fitness, who don't recognize the benefits or who don't have the financial means to do so. Let's look at each of these.Excuse #1 - I'm in the best shape of my life alreadyIf you asked most people 'are you in the best shape of your life' very few would say yes. And those that would say yes may still have untapped potential depending on what they've already achieved with their training. For example, someone may have lived most of their life as an obese person and now would consider themselves the healthiest they've ever been. But there is still room for them to improve and realize more gains.Excuse #2 - Skeptic of the scienceAs for the skeptic that doesn't believe supplements work, they may have had a bad experience with a previous supplement. But there is more and more research evidence that certain metabolites, such as omega-3 and creatine for example, offer health and performance benefits. To deny the benefits means refuting science. And there will always be some people that deny science and research. Consider the fact that there is a Flat Earth Society shows how some people will always refute the truth.Excuse #3 - Supplements are expensiveAnd when you consider the argument that supplements are expensive this may be true depending on what an individuals buys and how they use it. On the other hand you could argue that a particular supplement may improve...
