Military training and pregnancy increase women’s nutritional needs, specifically for vitamin D, calcium, iron, folate, and iodine. While HPRC always recommends choosing whole foods first, sometimes it can be difficult to get enough of those nutrients through food alone. When nutrient needs are higher than normal or when nutrient-rich foods aren’t available, vitamin and mineral supplements can help women to restore nutrient levels in their bodies. Just remember that you don’t need supplements unless you have known nutrient deficiencies, so talk to your healthcare provider before taking any supplement. Read more...

The Food and Drug Administration recently announced that methylsynephrine (also known as oxilofrine) “does not meet the statutory definition of a dietary supplement ingredient.” So what does this mean? Products containing methylsynephrine are adulterated and can’t be marketed legally as dietary supplements. Methylsynephrine is also prohibited in sport because it’s a pharmaceutical drug (not currently approved in the U.S) and a stimulant that increases blood pressure and affects heart rate. What’s more, some supplements have been found to contain methylsynephrine in amounts equal to or greater than pharmaceutical doses.
The consequences of taking methylsynephrine in large amounts or in combination with other stimulants aren’t entirely known, but one product containing this ingredient and other stimulants has been linked to nausea, vomiting, agitation, increased heart rate, chest pain, and cardiac arrest. If you’re considering taking a dietary supplement with methylsynephrine or oxilofrine on the label, you might want to think twice. For more from FDA, please see “Methylsynephrine in Dietary Supplements.”
SARMs (selective androgen receptor modulators) are unapproved, experimental drugs sometimes illegally marketed and sold as dietary supplement products. They’re also available on the Internet in other forms, but their use in sport is prohibited. Use of SARMs can affect military performance and readiness.
Operation Supplement Safety (OPSS) has an FAQ about SARMS, including a link to a list of more than 200 dietary supplements and other commercial products containing SARMs. The list also includes an extensive list of SARM names to help you identify them on product labels.
HPRC’s Ask the Expert feature is available if you have particular questions about these ingredients or any other questions about dietary supplements.
Many dietary supplement products are marketed as nootropics—substances intended to improve memory, focus, and overall mental performance. While some products contain vitamins, minerals, and plant-based ingredients, others contain drugs that are not legal dietary supplement ingredients. Read the Operation Supplement Safety (OPSS) FAQ about nootropics to learn more about these products and whether they are safe and effective.
Not all ingredients found in dietary supplements are legal, so read product labels carefully. For more information, visit FDA’s Dietary Supplement Products & Ingredients.
March is National Nutrition Month, a good reminder to eat healthfully and choose the best foods to fuel our bodies. This year’s theme is “Savor the Flavor of Eating Right,” which isn’t something we can often say about dietary supplements that come in the forms of pills and powders. If you’re looking for a supplement to lose weight, build muscle, or enhance your performance, HPRC always recommends choosing nutrient-rich foods first. They taste better and are better for you. Use the Operation Supplement Safety (OPSS) “Real Food” poster to see what foods can help you meet your goals.

Although DMAA is now illegal as a dietary supplement ingredient, some companies still offer products containing this substance. HPRC’s newest update of “Dietary Supplement Products Containing DMAA” lists those products still being offered on the Internet, as well as products that have disappeared from the market. Before you buy any dietary supplement, check this list and read the label to make sure it doesn’t contain this potentially dangerous ingredient. Based on federal policy, DoD considers such products illegal to use or possess. Don’t risk your health or your military career!
If a dietary supplement product contains something called a “new dietary ingredient,” manufacturers or distributors must notify the Food and Drug Administration (FDA) before marketing any product that contains the ingredient. Aside from this, FDA doesn’t review or approve dietary supplements before they’re marketed. So what’s a “new dietary ingredient,” what makes it different from other ingredients, and what has to be done before one can be used in dietary supplements? Find out in the OPSS FAQ about new dietary ingredients.

Chia (Salvia hispanica) seeds are rich in omega-3 fatty acids and fiber. As such, they have become a popular food item, and you can also find chia (seeds and oil) in many dietary supplements marketed to support heart and digestive health. On its own, chia will not produce a positive drug test. However, when you look at ingredient lists on product labels, don’t confuse Salvia hispanica (chia) with Salvia divinorum (Diviner’s sage), which is banned by some services. There are many types of salvia, so please read the OPSS FAQ about salvia for more information. If you’re interested in learning more about chia seeds, visit this webpage from MedlinePlus.
