The 2 Essential Supplements for a Plant-Based Diet

Fitness Workout for Men

If you’ve hopped on the plant-based diet bandwagon and given up meat, dairy, and eggs, you’re probably feeling like you’ve finally got the healthy-eating thing figured out. Unfortunately, as good as you may feel while following a vegetarian or vegan diet, you won’t get enough of certain critical vitamins and minerals from eating plants alone. Two key supplements can go a long way toward filling those the gaps.

Vitamin B-12 and Iron

Some people on a strict vegan or vegetarian diet begin to feel foggy or sluggish, and there’s a reasonable explanation for it. According to Douglas Kalman, Ph.D., R.D., and co-founder of the International Society of Sports Nutrition, the small deficiencies brought on by plant-based eating can lead to bigger issues long-term.



“From a cognitive or brain function standpoint, if you have insufficient intake of B-12 and insufficient intake of iron, it affects the health of your nerves. It affects cognition,” he says.

Vitamins

Following a completely vegetarian or vegan diet eliminates the most prevalent sources of B-12 and iron, which are typically found in meat and dairy. While it may not be noticeable in the first few months of going plant-based, the effects over time can add up. As a sports nutritionist for a university, Kalman never neglects to quiz his athletes on their eating habits.

“I have 18 teams every season, every year, and I go through and ask, ‘All right, who’s a vegan? Who’s a vegetarian? Who’s a regular meat eater?'” he says. “That way, I know who needs a little bit of extra attention about how to pick foods.”

There’s nothing wrong with choosing to eat a vegetarian or vegan diet, and Kalman himself was a vegetarian for eight years. If you do decide to forgo meat and dairy, though, supplementing with B-12 and iron can help prevent deficiencies that can lead to mental sluggishness and low energy. Follow the labels for dosage and usage instructions.

If you’re a lifter or other athlete, Kalman recommends educating yourself before limiting certain types of foods, so you know exactly which supplements you may need to fill the gap.
