Always read the disclaimer:
"These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure or prevent any disease."
Not only are those pills useless, they may be very dangerous, having never been medically tested.
Additionally, their "scientific" claims raise every red flag in the book: vague, unsubstantiated claims with no specific results or studies.
Time for some Education.......
Just because it has that disclaimer, doesn't mean that the supplement is harmful or non-effective. That disclaimer is required to be printed on all supplement labels as a result of the DSHEA act.
The DSHEA act is the law which was enacted to define a dietary supplement as anything taken orally which contains dietary ingredients, and is designed to supplement the diet. Much like a little pill that you make out of ingredients from your cupboard,
they can become harmful when taken in tandem with or within a certain amount of time of certain prescription drugs, that's why you should always tell your doctor if you are of have been taking a supplement, and why an EMT crew will ask you about medications (including supplements) that you have been taking if they arrive to help you in an emergency. There is nothing in a supplement that is inedible, or that has been shown to be dangerous upon ingestion in humans, except perhaps in the case of extremely large amounts being consumed in short periods of time (hypervitaminosis), but that can happen if regular food is over-consumed too.
Supplements may include: Vitamins, Minerals, herbs or botanicals, amino acids, and substances such as enzymes, organ tissues, glandulars and metabolites. Also notice that on the label it says serving size rather than dose, and has a supplement facts panel not unlike a nutrition information panel. The label must also mention the part of each plant used.
And the structure function statement that you mentioned is also required to be printed. All that means is that the supplement doesn't contain a chemical which is intended to diagnose or cure illness (like a regular drug is intended to do), and that people should be informed that the supplement has not been evaluated in that light. It is a regulation to keep supplement companies from claiming that their supplements can cure cancer or AIDS etc. If they want to claim that, they have to go through the FDA's drug approval process and prove their supplement to have the actual valuable medicinal properties, as well as the safety and efficacy to be useful in treating disease.
What supplement makers can do is make vague associations between their ingredients, and some of the benefits that those ingredients have been shown to have in other studies. Statements such as "Antioxidants have been shown to promote cell health" are acceptable for supplements.
So what I'm trying to say with all this is that you shouldn't write a supplement off as dangerous or useless just because it has a governmentally mandated disclaimer.
There is still regulation that goes into dietary supplements, but it's not the multi billion dollar, decade(s) long type of regulation that prescription and OTC drugs must go through which for obvious reasons in much more rigorous and important. An "extremely dangerous" supplement is still not going to make it to the shelves, unless perhaps your definition of "extremely dangerous" is different than mine.
Their scientific claims made by these companies are vague only in the sense that they don't have to necessarily be in reference to the supplement, but rather to it's ingredients.
They can freely cite highly published and respected studies as they pertain to an ingredient in the product. It's true that eating a good healthy and balanced diet will completely eliminate any need for taking one of these supplements, if you are getting something that makes you alert from a supplement, then diversifying your diet to include whatever plant source that ingredient came from will do just as good to help you.
In short, don't write them off as dangerous or bogus, but don't waste your money either! Just eat right, exercise, and get out of the house and off your computer once in a while. You'll get all the benefits of a supplement and more!
