What you’ll learn
What are the registered dietitian or nutritionist requirements? Should I do a 4-year nutrition undergraduate program? What are the top nutrition schools? Should I do a Masters or PhD in nutrition? What are the best nutrition graduate programs? So what are the best certifications and nutrition courses online?
I love fitness nutrition? However, for bypass and sleeve patients, the changes in digestion and nutrient absorption also mean that some supplements may not be tolerated or absorbed as well as others. Can heat and humidity destroy whey protein and other sports nutrition supplements e. However, once they are opened, they can be affected by humidity. Do not store these supplements in the refrigerator, because if you remove them and leave them open, moisture may accumulate due to condensation.
On the other hand, liquid supplements containing these ingredients, such as ready-to-drink sports drinks, are generally more sensitive to heat and can become unstable and degrade quickly. For example, tests by ConsumerLab. If you live a hot climate, it may be preferable to refrigerate these, particularly after opening. Should I be concerned that it is an ingredient in my supplement? Carrageenan is a substance derived from red algae, or seaweed, that is used to create a smooth texture and thicken foods such as pudding, yogurt, ice-cream, whipped toppings, milk including almond and soy milk , soups, and processed meats.
Carrageenan is sometimes also added to supplements to improve texture or thicken ingredients. It can be found in some multivitamins , vegan and vegetarian sources of omega-3 fatty acids, such as algal oil supplements , nutrition bars and protein drinks.
It was also an ingredient in one cocoa product tested by ConsumerLab. Food-grade carrageenan is considered safe by most regulatory agencies; however, some researchers who study carrageenan have raised concerns that carrageenan may be carcinogenic and cause inflammatory reactions. Immunocal is much more expensive than other whey protein isolates - is it worth the extra cost? However, Immunocal costs up to five times as much as other whey protein isolates, and there is not enough evidence to suggest it provides an advantage over less expensive brands.
I've heard that rice has high levels of arsenic. Does that mean rice bran oil does too? Some rice and products made from rice, like rice cakes, flour and cereals, have been found to contain a considerable amount of the heavy metal arsenic - although only a few exceeded the cancer-warning threshold of the State of California 10 mcg per daily serving.
Although arsenic can also occur in rice bran oil, it is believed to occur in much lower concentrations than in whole rice. One study of products in Japan found that rice bran oil contained only trace amounts of arsenic that were not of concern 0. These findings suggest that arsenic is not as easily taken up into the oily portion of rice as it is into other parts of the grain.
It should also be kept in mind that rice bran oil is typically consumed in much smaller amounts than products made from whole rice products. When choosing a protein powder, which protein source is best -- whey, casein, soy, pea, rice or egg? As discussed in more detail in our Protein Powders and Drinks Review , each of these can be a good source of protein, but certain protein sources may be better for particular uses and in certain people.
Whey protein contains the highest percentage of branched-chain amino acids, which can become depleted during exercise and are needed for maintenance of muscle. However, some studies have found rice protein and pea protein equal to whey in increasing strength and muscle when taken after resistance exercise. Casein is absorbed more slowly than whey and, for this reason, some athletes take it before bed to help counter protein breakdown. Soy protein can lower cholesterol levels and may have other heart health benefits.
Heavy metals such as lead, cadmium, and arsenic have been found in protein powders. Typically, these have been at very low levels — below limits for safe use.
When higher amounts have been found, it has been associated with added, non-protein ingredients such as cocoa powder a source of cadmium or bran from rice. Specific sources of protein should be avoided due to potential allergic reactions, food sensitivities, and medical conditions e. It is also important to understand differences in the forms of protein, such as concentrates, isolates, and hydrolysates. Do glutathione supplements work to prevent aging or for other conditions?
Although glutathione plays an important role in the body as an antioxidant, supplementing with glutathione has not been shown to slow aging or help with conditions associated with reduced levels of glutathione, such as cancer, cataracts, diabetes, and HIV infection.
Glutathione is a protein normally made in the body from three amino acids: We get small amounts of glutathione from foods, and this is normally broken back down to amino acids by enzymes in the digestive tract.
As discussed in the Glutathione article on ConsumerLab. However, a study in which large amounts of glutathione were given daily for six months did show an increase in glutathione levels. Nevertheless, there are no studies showing a clinical benefit on any disease or medical condition from taking glutathione supplements. For more information, see the Glutathione article on ConsumerLab. Also see answers to the following questions: What is the best protein supplement for vegetarians and vegans?
As discussed in our review of protein powders , two very good sources of protein — whey and casein protein — are both derived from milk, so products that contain these may be suitable for vegetarians but not for vegans. Whey and casein are both complete proteins, meaning that they contain all of the essential amino acids. Whey protein is particularly high in branched-chain amino acids, which are important to replenish after exercise and are needed for maintaining muscle.
If you prefer plant-based protein or are vegan, protein powders made from soy, rice, pea and hemp, or a mix of these sources, can be good choices. Soy protein is a complete protein, and is considered the most "heart healthy" -- but should not be taken if you have a soy allergy or thyroid condition.
Rice and pea proteins can also provide all of the essential amino acids, and some studies have found them to be equal to whey in increasing strength and muscle when taken after resistance exercise.
Hemp can also provide all of the essential amino acids, and is particularly high in the branched-chain amino acid arginine, although there is little research on its use for muscle building or sports recovery. Be aware that although these plant-based proteins provide all the essential amino acids, the ratios of these vary by protein source. Consequently, it's generally recommended that a mixture of sources be used, such as combining a grain-based protein, like rice, with a legume-based protein like pea protein.
Arsenic contamination is a concern in rice-based products -- see the Warning and Quality Concerns for more about this; however, ConsumerLab. See the ConsumerTips section of the Protein Powders Review for more about these different types of protein. Also see our Top Picks among supplements made from each protein source.
To be sure a protein supplement does not contain any added ingredients which are non-vegetarian or non-vegan ingredients, you can check the full Ingredients List provided for each protein supplement tested by ConsumerLab. John Berardi gives you a sneak peek at the Level 1 Certification.

The fact is this: To give you a very specific example: To give you a counter example, in our Precision Nutrition Coaching program, clients average around 15 pounds of fat loss in the first 6 months. But keep in mind: Our coaching is percent online. They get those results without ever meeting us in person. If they work with a coach or trainer while doing Precision Nutrition Coaching which can help them work harder in the gym and stay accountable locally , they lose closer to 25 pounds of fat in 6 months.
Because once you really understand both, on a deep level, you can deliver results that are impossible with exercise alone.
Simply put, the past 25 years of published research show that while exercise alone can promote very small changes in body fat, lean mass, and the associated health markers, those changes are almost negligible. In fact, one published review, a meta-analysis of more than previous exercise studies done over 25 years, showed that about 6 months of supervised exercise programming will produce only 9 pounds of weight lost. If we assume 50 percent of that weight lost is fat which is a safe assumption, based on the research , that means that clients can expect to lose around 4.
After all that time and money spent, would an overweight client even notice 4. Would their cholesterol be significantly lower? During the first 6 months of the online-only program, the average fat loss is around 15 pounds. In addition, we see hundreds of reports of clients being taken off blood pressure, cardiovascular disease, and diabetes medications. But no one is teaching this stuff. Nothing out there covers the specific problem: How to deliver nutrition coaching in an exercise, personal training, health, rehab, or sport coaching environment.
I wanted to create a new kind of program: Well, for one, I have pretty vast exposure to almost every aspect of health, fitness, and nutrition. The purpose of this coaching is simple: And I mean everything. So we have detailed psychometric personality profiles on our clients. We track compliance and every measurable and relevant behavior.
And, of course, we regularly collect photos and monitor body composition and performance outcomes. Success here meaning compliance, consistency, and ultimately, fat loss, muscle gain, and life-changing health improvements. It takes a long time to gather this kind of information, especially since no one in the health or fitness industry has ever done anything like it before.
So this is coming from first-hand knowledge that we use ourselves every day. This certification is based on real client results, and a reliable and reproducible system for monitoring and achieving those results.
