More than 50% of people in the US take dietary supplements to enhance an aspect of their health. Maybe you take supplements on a regular basis...

After all, the American public spends billions and billions of dollars each year on a wide array of pills and powders.

Unfortunately, a lot of what is sold to the public is under the umbrella of deceptive advertising. We are talking about fake pictures and ridiculous testimonials. Even worse, some supplements are extremely unhealthy.

Thus, here are 4 dangerous myths about supplements:

1. They don't have side effects: Look, just because the supplement companies market their products as natural does NOT mean there are 100% safe. In fact, there are many "natural" substances that are lethal. Also, remember that a lot of supplements are super concentrated concoctions of different ingredients. Thus, at this level, the naturalness tends to fade.

2. They are backed by valid studies: Most of the sexy charts and graphs you see on the labels and advertisements are made up. You see, the bulk of the data is performed by biased entities that are directly related to the supplement companies themselves.

3. They take your health as a top priority: There is a lot of money to be made selling supplements. And when there is so much money at stake, it is very easy for companies to lose sight of ethics. And the supplement industry is no exception here.

4. Word of mouth is reliable: Word of mouth is definitely convincing, but it should not be taken as the end all be all to a supplements efficacy. You see, the placebo effect is extremely strong. In fact, if you gave a sugar pill to 100 people, 40 would claim a noticeable difference!

I recommend staying on the safe side here. And the best way to do this is to only take supplements that have undergone peer reviewed research. You see, peer reviewed research is the closest we can get to the truth. And with the truth you will be better informed as to what decisions are right for your health.
