Whether you’re a plant-based-eating novice or a vegan veteran, it is possible—and extremely plausible—you’re missing out on key nutrients. According to the Center for Disease Control (CDC) and the U.S. Department of Agriculture (USDA), nine out of ten Americans are lacking one or more key dietary nutrients. Even athletes whose job it is to get optimal nutrition and have access to professional dietary advice had at least two or more nutrient deficiencies according to an International Society of Sports Nutrition study.

Vegan and plant-based diets in particular are at-risk for some specific deficiencies since they miss out on nutrients commonly derived from animal sources. B12 for example is one of those critical nutrients. B12 is produced by bacteria living in soil; the soil is then eaten by animals thus the B12 makes it into bodies of animal-consuming humans. “The only reliable source of B12 comes from animal products and supplements,” says Alex Caspero, a registered dietitian and founder of Plant-Based Juniors. “Everyone on a plant-based diet needs to take B12. While B12 is found in fortified foods, the amount isn't reliable and therefore supplementation is the best source of B12,” Caspero stresses. And, B12 is not only missing in vegan diets. Studies have shown nearly 40 percent of the population suffers from B12 deficiencies.

Caspero also says DHA is important especially for certain populations. “Not everyone needs DHA, though supplementation is recommended for all pregnant and breastfeeding women.”

Caspero points to the importance of ALA, one of the Omega-3 fatty acids that support healthy brains and heart health. ALA is the plant-based version of omega-3 fatty acids, which can be converted to DHA and EPA. You hear a lot about omega-3 fatty acids derived from fish, but there are in fact effective vegetarian sources. Vegetarian sources of omega-3’s you May find in supplements are typically derived from algae.

Vitamin D is also an important nutrient to supplement especially since studies have shown that 42 percent of the US population is Vitamin D deficient. While many plant-based kinds of milk are fortified with Vitamin D, and there are whole-food food sources, like mushrooms, still you might not be reaching your recommended daily intake.

Choosing a supplement to fit your needs

There is an overwhelming abundance of supplement options on the market today. For vegans, you’ll want to make sure the product is cruelty-free (not tested on animals) and ingredients only include non-animal sources. You would be surprised to learn how many vitamin brands use animal-derived ingredients. For example, gelatin, commonly found in vitamins, is typically derived from animal collagen. So read the labels or simply find a dedicated vegan brand.
