Here’s what resident nutritionist Michelle Pellizzon has to say about vitamins. “Ideally, we’d get most of our nutrition from food—but eating three balanced meals a day while trying to crush it at work, fit in a workout, and get eight hours of sleep can be a challenge. That’s where supplements come in.” It makes sense—vitamins act as your nutritional sidekick, stepping in to fill the gaps in your diet when you need a little boost.

What Different Vitamins Do

Not sure which vitamins you need? (A good first step is to check in with your doctor and have a blood test to check for any micronutrient deficiencies.) Here’s a look at what some of the key letter vitamins can help you with.

• Vitamin A: The two types of vitamin A are retinol (found in animal sources like dairy milk and eggs) and beta carotene (found in fruits and veggies like carrots, tomatoes, and papaya). This vitamin is known to support immune function, cell reproduction, and eye health.


• Vitamin B: There are eight B vitamins in total, and they work together to help the body process food (especially carbs) and convert it into either energy or glucose. This group of vitamins is sometimes referred to as the “anti-stress vitamins” and may support a healthy immune system.


• Vitamin C: You can find vitamin C in lots of fruits and veggies, like blueberries, cauliflower, cabbage, oranges, and leafy greens, to name a few. This nutrient is known for helping our bodies repair tissue, and is a component in collagen creation.


• Vitamin D: If we’re getting technical, vitamin D is actually a hormone, and is believed to help improve your mood. The best source of vitamin D is through sunlight. After that, choose fatty fish, egg yolks, and fish liver oil. Many people are deficient—check with your doctor to find out a recommended dose.


• Vitamin E: Vitamin E functions as an antioxidant in our bodies, which may help protect cells from free radicals, and support the production of red blood cells. Find this vitamin in foods like almonds, avocados, kale, eggs, and olive oil.
