Supplementation is popular for everything from muscle gain to hair and nail growth. But did you know that supplements are not actively regulated by the US Food and Drug Administration?

What is a supplement? 
A supplement is any product that has a “Supplement Facts” label rather than a “Nutrition Facts” label. This can include multivitamins and pill supplements but also protein powders, herbs, probiotics, teas, oils, and other food-like products. 
By FDA standards, supplements are preemptively considered safe until proven unsafe. Where food and pharmaceuticals have to meet rigorous standards in order to be proven safe for public consumption, supplements are only taken off the market if adverse events occur.  

Why is regulation important?
Lack of regulation before market leads to an enormous loophole in product quality. Products can and have been shown to manipulate consumers by putting ingredients on the Supplements Label that are not actually in the product. A product stating it contains 500 mg of calcium does not, by any law or standard, have to include 500 mg calcium. Many supplement manufacturers have incentive to put less in their product than advertised in order to save money. 

The quality of supplement ingredients also does not have to be traced or regulated, so there is limited ability to guarantee freshness or that the ingredients included contain active properties. Supplement manufacturers may also put other “filler” ingredients into their product that are not, and do not have to be, listed on their label. They are also not required to test for contamination.

Some supplements carry a certified organic label; while this means that any of the ingredients they use meet standards of organic products, this has no bearing on whether what is listed on the label is in the product you consume.

For consumers, this means potentially wasting anywhere from $10 to $50 on a product that promises to help with muscle gain or hair and nail growth, when the product quality may be deeply compromised.
 

What can we do to protect ourselves? 
The number one way to make sure the supplements you purchase are of a high quality is to look for a third-party certification statement. For supplement companies wishing to gain consumer trust and elevate the quality of their product, they will hire an independent laboratory to test their products. This testing can verify that what is stated on the label is in the product.

Supplements that have undergone this testing are able to bear the logo of that third-party testing company. The most well-recognized is the U.S. Pharmacopia or “USP” seal of certification. The Nature Made brand has the majority of their products verified by USP and can be assumed to be safe and containing what the label states they contain. 

Two other popular verification companies are NSF International (“NSF”) and Consumer Lab (their symbol looks like a science beaker.)  Of note, products by GNC and the Vitamin Shoppe do not appear to utilize third party verification.

Final Takeaway
Supplements can cost a lot of money; take every possible precaution to make sure that the money you’re putting down is going toward what you think it is. Find brands that utilize third party certifications and stick to them! If your supplement of choice doesn’t seem to have a brand that uses a third-party verifier, read a little bit more about the supplement. More digging may show that the supplement doesn’t have any real scientific evidence to do what it claims to do in the first place.  

There is a lot of fear these days regarding sugar intake and its role in long term health. High sugar intake has been implicated in the main diet-related chronic illnesses: type 2 diabetes, heart disease, cancer, and even Alzheimer’s.

This fear drives many diets out there to encourage minimizing or even completely eliminating sugar from the diet, including natural sources like fruits (fructose) and dairy (lactose). Grains also get lumped into this category, as the carbohydrate in grains gets broken down into the same basic unit sugars do: glucose.

As a nutrition professional I don’t believe sugar should be eliminated from the diet. It’s a surefire way to build cravings for it and overeating it later down the line. The body also requires glucose to run efficiently – particularly your brain and muscles. Well-timed sources of sugar can actually provide some benefit, as any endurance athlete will be quick to validate.

Here are a few guidelines to follow when making decisions about sugar so you don’t go overboard in either direction!

1. Is it a natural source of sugar?
   There are two main natural sources of sugar: fruit (fructose) and dairy (lactose). For dairy, there are typically about 12 grams of natural sugar per 8-ounce serving. Fruit varies greatly, but as an example there are about 19 grams of sugar in an apple, 17 grams in an orange, and 15 grams in a cup of blueberries. 

   The average nutritional recommendation for dairy is 3 servings per day, and for fruit it’s 2 servings per day. If you stick to your general recommendations, that equals about 60-70 grams per day.

   This source of sugar comes packed with nutrients; for lactose, you’re also getting protein, calcium, and vitamin D — all of which are nutrients many Americans are looking to increase in their diets. For fruits, it’s micronutrients like potassium and folate, as well as fiber and protective antioxidants.

   Eliminating these sources of natural sugar also eliminates all of the nutritional benefit that comes with it! Stick to and enjoy your dietary recommendations, and the natural sugars that come with them.
   

2.  Is it an artificially added sugar?
   Any food product that has added sugar is required to list that in the ingredient list of the nutrition facts label. For example, any energy bar that does not have dairy or fruit will contain added sugar. Look to the ingredient list to identify the source. If the ingredient list includes “sugar,” and there are 18 grams of sugar in the bar, then all 18 of those grams are added sugar.

   The tricky thing here is that added sugars have many names. The more obvious will be sugar, honey, and maple syrup. Other forms of added sugar include agave, brown rice syrup, molasses, caramel, corn syrup, corn sugar, high fructose corn syrup, dextrose, fructose, maltose, lactose, sucrose, and nectars — to name a few!

If you want to evaluate your sugar intake for a week or two, pay attention to food labels, take note of grams of sugar per serving, and then check the ingredient list to see whether any sugar is added.
 

1. Does it fall within my daily recommended guidelines for sugar intake? 
   The Dietary Guidelines recommend limiting added sugars to less than 10% of their total daily calories as part of a healthy diet. For the average 2,000 calorie diet this amounts to 200 calories, or 50 grams of sugar, per day. As a reference point, there are about 4 grams in a teaspoon of sugar, so that’s about 12 teaspoons of sugar per day.

   There are 2 ways to stay within your recommended sugar guidelines without completely eliminating it. First, stick to the recommended servings and portion sizes of dairy (3 per day) and fruit (2 per day). Second, read labels to determine amounts of sugar in a product, and whether there’s any added sugar in the ingredient list.

   If the product contains dairy, subtract about 12 grams of sugar per serving to account for natural lactose. If the product contains fruit, subtract about 15 grams of sugar per serving to account for natural fructose. Whatever is left is considered added sugar. Try to limit that amount of added sugar to less than 50 grams per day and you’re armed with everything you need to know to navigate nutrition labels for sugar!
