Omega-3 fatty acids are important for brain development and function, but they also may help protect against damage from concussions and other traumatic brain injuries (TBIs). Several animal studies have shown that omega-3 supplements given before or after a traumatic event not only reduce the severity of damage in certain parts of the brain but also improve mental performance during recovery. Similar studies haven’t been conducted with humans yet, and although the results of these animal studies are promising, there isn’t enough current evidence to recommend taking omega-3 or fish oil supplements to reduce the risk of or assist in the recovery from concussions or TBIs. In addition, FDA has warned consumers to avoid using products marketed for these purposes. For more information, please read FDA’s Consumer Update.
Although omega-3 supplements haven’t been proven to help with TBIs, omega-3s are still important for your brain, heart, and overall health. It’s best to get your omega-3s from food, but if you choose to take supplements, do so under the supervision of your doctor. For more information on omega-3 supplements, please visit “Omega-3 Supplements: In Depth” from the National Center for Complementary and Integrative Health.
Omega-3 fatty acids make up a family of polyunsaturated fatty acids. They are important to our health, and since our bodies can’t make them, we need to obtain them from the foods we eat. Omega-3 fatty acids may reduce the risk of heart disease and play an important role in our cell membranes. So, eating more can benefit the body in many ways.
The most widely available dietary source of EPA and DHA is cold-water oily fish such as salmon, herring, mackerel, anchovies, and sardines. Other oily fish such as tuna also contains omega-3 fatty acids but in lesser amounts. Some other sources of ALA are walnuts and canola, soybean, flaxseed/linseed, and olive oils. For additional information, including health benefits of omega-3 fatty acids, read this fact sheet; and for omega-3 content in various foods, try this infosheet from HPRC.
Salmon is commonly touted for its omega-3 fatty acids. HPRC recently received a question about what foods other than salmon are the best sources of omega-3 fatty acids. For a complete answer, including the recommended intakes from the American Heart Association, please see HPRC’s answer.
Wandering down the aisle of a store looking for a dietary supplement can be overwhelming and intimidating. There are so many to choose from, and we often have to make our choices based on advertising claims and rely on the manufacturers for ingredient information. Does the supplement actually have the ingredients claimed on the label? Will it have the reported effect on our health?
The Natural Medicines Comprehensive Database is the “scientific gold standard” for evidence-based information on dietary supplements and natural medicines, including drug interactions, effectiveness, safety and use, and more. HPRC has partnered with Natural Medicines Database to allow healthcare providers, Warfighters, and military families to search this comprehensive database in order to make informed decisions about dietary supplement use. The Natural Medicines Database also has “Natural MedWATCH,” which allows users to report an adverse event associated with the use of dietary supplements or natural medicines so that they can then forward the report on to the appropriate regulatory agency.
By going to the HPRC homepage, users can access any of the three database choices provided: Natural Medicines Comprehensive Database for Health Professionals, Consumers, or Natural MedWATCH. After choosing one of the sites, first-time users should sign up for an account, which is done with an active DoD email address. Once inside this vast database, a user can search for an individual natural medicine ingredient of interest or a brand name product.
The professional version of the database includes:
- Evidence-based monographs available for individual natural ingredients.
- Scientific names of ingredients
- Information on safety, effectiveness, mechanism of action, adverse reactions, interactions, and dosage/administration (which are not necessarily recommended or safe doses) of ingredients
- Patient handouts
- Brand-name product searches by ingredient
- “Natural Product Effectiveness Checker” for medical conditions
- “Natural Product Drug Interaction Checker” for a list of drugs/natural products interactions
- Comprehensive information on brand-name products, including ingredient lists and summary reports on effectiveness, interactions, and adverse effects.
- Up-to-date information for over 60,000 brand name products
The consumer version, for military families and Warfighters, contains the same research-based information on herbal remedies, dietary supplements and other natural products, but in an easier-to-understand version. An important point consumers should be aware of is that it may be necessary to research each individual ingredient in a product before making a decision to use it for health benefits.
So, if you want to find credible, evidence-based information on dietary supplements and/or natural products, search the Natural Medicines Comprehensive Database. Evaluating natural health products can be daunting and there is no other comprehensive, reliable site like it to guide you in making your decision.
