My Top 5 Most Commonly Recommended Dietary Supplements
The world of dietary supplements can be difficult to navigate. It’s easy to get lost in supplement aisles at the grocery store or overwhelmed by the numerous products being advertised to us in the media for a variety of purposes.
While I always take a food-first approach with all of my clients (meaning that I aim to help them meet all of their nutrient needs through foods), there are often times when a dietary supplement is needed. Supplementation may be necessary due to certain dietary patterns, disease states, or training demands. Additionally, some people benefit from supplements to boost reserves of nutrients, hormones, or neurotransmitters that otherwise would become deficient.
To help you sort through what dietary supplements you can trust and which supplements may be right for you, I put together a list of my top 5 most commonly recommended dietary supplements and recommendations on what to look for when purchasing supplements.
1. Omega-3 Fish Oil
Omega-3 fatty acids are anti-inflammatory, which means they help with decreasing inflammation caused by stress, toxins, or injury. They also are essential for forming the structure of cell membranes. Most Americans don’t consume enough omega-3 fatty acids; according to a recent analysis completed by the FASEB journal, 83.5% of Americans do not consume enough seafood to meet minimum omega-3 recommendations through the diet. The most current recommendations from Harvard Medical school are that anyone who does not eat enough omega-3 fatty acids through the diet should supplement with 1g of omega-3 fatty acids per day to decrease inflammation and the risk of cardiovascular events.
2. Vitamin D
Vitamin D serves several critical functions in the body, including: promoting calcium absorption, which keeps bones strong; supporting immune function, cell growth, and cell division; and reducing inflammation. This nutrient is not found naturally in many foods aside from fatty fish (such as salmon, tuna, or mackerel) and several mushroom varieties, though it is added to several dairy products such as milk or yogurt. Vitamin D can also be synthesized with sufficient exposure of the skin to sunlight. Because these foods often comprise just a small part of the typical America diet and adequate sun exposure is not always possible (particularly in cooler climates), vitamin D deficiency is one of the most common nutrient deficiencies in the US (about 42% of us are deficient). For someone who is deficient, supplementation is likely necessary, though dosage and length of supplementation will vary based on the severity of the deficiency.
GABA stands for Gamma Aminobutyric Acid and it is a neurotransmitter that is made naturally in the body. Its primary role is to reduce fear and anxiety. This neurotransmitter is not available in many food sources (only a few fermented foods, such as kimchi or tempeh), and GABA levels in the body can become deficient during periods of high stress. Additionally, individuals with certain medical conditions tend to have low levels of GABA, including those with seizure disorders, ADHD, panic disorders, or mood disorders. GABA supplementation has shown to be most effective for those who experience anxiety. I have found it to be particularly useful for myself and clients who have difficulty falling asleep at night due to racing thoughts.
4. Vitamin B-12
Vitamin B-12 is essential for DNA and red blood cell production. This nutrient is only available from animal sources, which means that anyone following a vegan or predominantly plant-based diet will need to take a dietary supplement. Additionally, anyone who has undergone gastric bypass surgery will need to supplement with B-12 because absorption of vitamin B-12 occurs in the stomach (which has largely been bypassed), not the intestines as is the case with most other vitamins and minerals. Vitamin B-12 deficiency can also be common in the elderly because our digestive capabilities tend to weaken as we get older.
BCAAs, or Branched Chain Amino Acids, are a group of 3 amino acids that have been shown through research to assist with reducing muscle soreness after exercise. Some studies have also shown that they can help with increasing muscle growth. These amino acids (leucine, isoleucine, and valine) are found naturally in many foods, including meat, dairy, and eggs. However, individuals following a vegan or plant-based diet may not consume enough through the diet to meet their needs. Additionally, anyone engaging in a strenuous weightlifting program requires additional protein intake for recovery, and a BCAA supplement can help with supporting these needs during and after exercise or between meals. You can learn more about BCAAs by visiting my earlier blog post on this topic.
These supplements represent the most common recommendations I make for my clients, which include athletes and fitness enthusiasts of all ages. Remember, dietary supplements are not regulated by the FDA, and therefore you cannot trust that every supplement on the shelf or online is safe. I would always recommend talking with your doctor or dietitian first before starting any new dietary supplement. To see the brands I typically recommend for different supplements, visit the link to my Fullscript dispensary on the Products page of my website. Fullscript is an online dispensary that can only be used by licensed healthcare professionals (such as doctors and dietitians) to recommend professional-grade supplements of the highest quality, purity, and potency.
If you are ever looking for supplements yourself, please look for a third-party seal to ensure the supplement has been verified for quality, purity, and potency. Examples of third-party seals include USP, Informed Choice, NSF, and GMP.
