A dietary supplement is a manufactured product intended to supplement the diet when taken by mouth as a pill, capsule, tablet, or liquid. A supplement can provide nutrients either extracted from food sources or synthetic, individually or in combination, in order to increase the quantity of their consumption.
The class of nutrient compounds includes vitamins, minerals, fiber, fatty acids and amino acids. Dietary supplements can also contain substances that have not been confirmed as being essential to life, but are marketed as having a beneficial biological effect, such as plant pigments or polyphenols. Animals can also be a source of supplement ingredients, as for example collagen from chickens or fish. These are also sold individually and in combination, and may be combined with nutrient ingredients.
In the United States and Canada, dietary supplements are considered a subset of foods, and are regulated accordingly. The European Commission has also established harmonized rules to help insure that food supplements are safe and properly labeled. Among other countries, the definition of dietary supplements may vary as drugs or other classes of ingredients used in supplement products.
In addition to vitamins, proteins or dietary minerals, supplements are also available for body builder.
Bodybuilding supplements are dietary supplements commonly used by those involved in bodybuilding, weightlifting, mixed martial arts, and athletics for the purpose of facilitating an increase in lean body mass. The intent is to increase muscle, increase body weight, improve athletic performance, and for some sports, to simultaneously decrease percent body fat so as to create better muscle definition. Among the most widely used are high protein drinks, branched-chain amino acids (BCAA), glutamine, arginine, essential fatty acids, creatine, HMB, and weight loss products. Supplements are sold either as single ingredient preparations or in the form of “stacks” – proprietary blends of various supplements marketed as offering synergistic advantages. While many bodybuilding supplements are also consumed by the general public the frequency of use will differ when used specifically by bodybuilders. One meta-analysis concluded that for athletes participating in resistance exercise training and consuming protein supplements for an average of 13 weeks, total protein intake up to 1.6 g/kg of body weight per day would result in an increase in strength and fat-free mass, i.e. muscle, but that higher intakes would not further contribute. The muscle mass increase was statistically significant but modest – averaging 0.3 kg for all trials and 1.0–2.0 kg, for protein intake ≥1.6 g/kg/day.
As of 2010, annual sales of sport nutrition products in the United States was over US$2.7 billion according to a publication by Consumer Reports.
Creating an industry estimated to have a 2015 value of $37 billion, there are more than 50,000 dietary supplement products marketed just in the United States, where about 50% of the American adult population consumes dietary supplements. Multivitamins are the most commonly used product. For those who fail to consume a balanced diet, the United States National Institutes of Health states that certain supplements “may have value.”
In the United States, it is against federal regulations for supplement manufacturers to claim that these products prevent or treat any disease. Companies are allowed to use what is referred to as “Structure/Function” wording if there is substantiation of scientific evidence for a supplement providing a potential health effect. An example would be “_____ helps maintain healthy joints”, but the label must bear a disclaimer that the Food and Drug Administration (FDA) “has not evaluated the claim and that the dietary supplement product is not intended to “diagnose, treat, cure or prevent any disease,” because only a drug can legally make such a claim. The FDA enforces these regulations, and also prohibits the sale of supplements and supplement ingredients that are dangerous, or supplements not made according to standardized good manufacturing practices (GMPs).

Hey what’s up guys, Sean Nalewanyj here , BodyTransformationTruth.com, and in this video I want to give you a basic bodybuildnig supplement tip by explaining why in most cases, you should not take advice from people who work in supplement stores.
For an average beginner who hasn’t done a lot of research on their own when it comes to bodybuilding and fitness supplements, taking advice from sales people who work in supplement stores and using that as your source of research is very rarely going to be a good way to determine which supplements actually work and which ones you should include in your muscle building or fat loss program.
Now obviously there are genuinely knowledgeable and genuinely honest people out there who work in fitness supplement stores and who do the best they can to give their very best advice, but this is definitely the exception rather than the rule. (If you are someone who is watching this and who does work in a supplement store and who does give good advice then this is obviously not directed at you)
I actually personally worked at a supplement store over 10 years ago when I was first starting out (a very big one that a lot of you might shop at) and I know firsthand that there’s basically no qualifications needed at all to get hired there. You literally are not required to have any prior knowledge about supplements or nutrition, and many of the people who work there don’t, and I have no doubt that that’s true of a high percentage of other supplement stores that you might shop at.
Not only that, but a lot of these people literally don’t even train, and yet they’re giving advice about supplements and nutrition, and even training sometimes to people who do.
And then on top of that they’re often paid partially on commission, and different products will have higher and lower commissions attached to them, and the sales people there are encouraged to push certain products over others, even if that’s not in the best interests of the customer. And of course your sales performance is also being tracked so there’s a certain level of pressure there to just sell a lot of stuff period.
So my basic advice here is that if you’re buying supplements locally, then just do your research beforehand. Know what it is that you’re going to buy before you go in there and don’t make the mistake of thinking that just because somebody happens to work in a supplement store that they’re actually knowledgeable about supplements or about proper nutrition.
In my experience of working in multiple stores and also going in to shop for my own supplements at literally hundreds of different stores over the last 10 plus years, I can tell you for sure that although some are knowledgeable, most of them really don’t have a clue of what they’re talking about.
It’s really not uncommon at all for people to waste hundreds or even thousands of dollars every year on bodybuilding supplements that literally do nothing at all for their results, so I’m just making this video to try and help you save some money and to help you simplify your program as well.
So bottom line, take some time to do your own independent research. I have a ton of evidence-based videos on this channel as well as over on my blog covering a wide variety of supplements for building muscle and burning fat and I’ll link that in the description box, examine.com is an awesome resource, and also if you just want a very basic primer about the supplements that I recommend (I’m not affiliated with any specific supplement companies) then you can go ahead and grab my “No B.S Fitness Supplement Guide” using the link in the description box.
