Do Dietary Supplements for Weight Loss Require FDA Approval or Clinical Trials Before Being Sold?

It is a common misconception that the FDA requires dietary supplements for weight loss to be approved for use before they can be marketed.

Many people also think that a "clinical trial" must be ran on the product before it can be legally sold. This is not only untrue, but quite naive.

I'm Lactose Intolerant, Can I Still Use Whey Protein?

Milk is one of the easiest ways for bodybuilders and strength athletes (or athletes in general) to get protein. Other dairy products, such as the popular Greek yogurt, are great for protein as well. Those folks who are lactose intolerant may lament not having this resource. This leads to a common question: Whey comes from milk, so can I use it if I'm lactose intolerant?

Consuming Whey Protein and Poor Appetite in Strength Training

The video below goes very deep into the lore of whey protein, including the way it is perceived as a nutraceutical which should be "taken" instead of consumed. The case is made that whey is a food and not a medicine, and should and can be treated as such.

Myths about the danger of whey and many other details are discussed, including warnings about consuming too many "liquid calories," the anabolic window of opportunity, and nutrient timing in general. Of special interest may be the discussion concerning strength trainees with poor appetites. How does whey fit in with this problem?

What is Sweet Dairy Whey and Can I Use it as a Whey Protein Supplement?

There are some companies that sell "Sweet Dairy Whey Powder" in bulk to consumers. This is very cheap, by the pound, compared to the typical whey protein supplement powders most strength training or bodybuilding trainees buy, and the price of whey protein has gone way up in the last year or so. The price of sweet dairy whey powder ranges from 3 to 4 bucks a pound, but it's possible to get it as low as one dollar a pound, if you buy in bulk. These powders are not flavored, and, despite the word sweet, are not sweetened.

Chelated Mineral

Chelated Mineral: A mineral that is chemically bound to another substance, which is usually an amino acid. Some examples are ferrous fumarate, chromium picolinate, and selenocysteine (chelated zinc). Chelated mineral supplements are often claimed to be better absorbed by the body since these forms are closer to how the minerals appear in the foods we eat. There is little direct evidence to support this claim. These minerals may be easier on the stomach, though.

Mistaken Reasons that People Take Vitamin and Mineral Supplements

Many people take vitamin and mineral supplements, not because they have a poor diet, but as added insurance against a lack of certain nutrients. This is probably not needed at all but the attitude is better safe than sorry and a little extra won't hurt. The fact is, extra will not likely do anything but cost you money. Still, many people have more specific reasons for taking supplements, usually because of ideas they have derived from nutrition misinformation. This article explores some of these reasons.

Whey Protein Processing, Terms and Definitions: Countering the Misconceptions About Whey Protein Including 'Raw' Whey

By Eric Troy

There is so much obsession, confusion, and supplement company shenanigans concerning whey protein products, I thought that what everyone needed was a thorough overview of the whey manufacturing process. That is, the whey powder manufacturing process.

Supplement companies use our ignorance against us: our ignorance of what whey is, how it is processed, and what all the terms attached to it mean.

Food Label Zealots, Chemicals, Supplements, and Natural Food: Want Some Chlorophyll?

As a continuance of my assault on the misleading ideas about "natural" food, this is yet another follow-up to a series of blog posts where I discuss chemicals in foods and the concept of natural. In the last one I talked about the difference between chemicals as nutrients and chemicals as pharmacologic agents. I explained that some chemicals in food do have a physiological affect beyond their basic biological functions. Others, such as compounds in herbals used for medicinal purposes simply have no function as a "nutrient." All of these, though, have one thing in common and that is summed up by saying that "The poison OR the remedy is in the DOSE." This is important in helping us recognize the difference between nutrition information and alternative medicine information.

Vitamin B12 (Cyanocobalamine) - When, How, and Why to Supplement

By Ken Adams, M.D. and Scott E. Conard, M.D.

Sources and Physiologic Functions

Sources

Liver, kidney, muscle meats, eggs, cheese, milk, and fish are excellent sources of vitamin B12. It is not found in plant foods or in yeast. Fermented foods such as soy sauce, tempeh, and miso, and fortified foods such as soymilk are also good sources of this vitamin.

Heavy Metals Found In Protein Shakes: Should You Stop Drinking Them?

A recent investigation on protein drinks has been causing waves of concern or even alarm to ripple through the fitness and bodybuilding world. Supplement companies are up in arms and people are wondering whether they should stop drinking protein shakes after the magazine said they tested 15 protein drinks for heavy metals (arsenic, cadmium, lead and mercury) and 3 of them came up above the proposed safe limits…

Dietary Supplement Ripoffs to Avoid: Amino Acid Pills

There is no long-term advantage for the strength trainee to taking expensive free form amino acid powders over simply ingesting whole proteins. However, if you do buy an amino acid powder (which I don't suggest) you expect it to contain single free form aminos acids, right?

Never trust the front label. Check the ingredients. The supplement ripoffs I am referring to are so-called amino acid capsules that actually contain overpriced whey or casein protein. Not free form single aminos but whole proteins compressed into a pill or put in a capsule. They will typically list an amino acid profile very prominently on the back of the label. This profile is nothing more than the typical amino acid yields of the whey or casein sources they use. When whey is used it is usually a mixture of whey protein concentrate or a mixture of concentrate and even cheaper non concentrated whey. Some may contain concentrates and isolates.

Tryptophan Supplements: Do They Work and Are They Dangerous?

Many people, with or without any scientific evidence, are firmly convinced that the particular foods they eat have a direct influence on their mood, anxiety level and alertness. Perhaps the most well known manifestation of this belief is that certain foods make us sleepy, particularly those with high levels of the amino acid tryptophan. Turkey, at least in the US, is thought to cause sleepiness due to it's high level of tryptophan and this is said to explain why we are so desperate for a nap after Thanksgiving dinner.
