Types of Vitamins and Supplements

When it comes to vitamins, there are many different forms to choose from.


This is the most common and convenient type with two outer shells that hold the dry ingredients.

Liquid Vitamins

Ideal for individuals who have difficulty swallowing pills, liquid vitamins have increased in popularity. They’re often flavored and can be taken by the spoonful or added to your favorite beverage. 


Powders are another good option for those who have difficulty swallowing. Powders can be mixed with water, milk or added to smoothies and yogurts.


Softgels are typically used for oil or liquid-based supplements (like Vitamin D) and are easier to swallow than tablets or capsules.


Tablets often contain many inactive substances that dissolve but can cause stomach upset in certain individuals. They are an economical choice.

Gummy Vitamins

What began as a way to get children to take their vitamins, quickly expanded to adult use. Gummies’ delicious flavors, however, usually means less nutritional value, making it among the least effective way to consume vitamins.


Americans’ love of convenience has given rise to vitamins brewed with your coffee, patches that adhere to the skin, and tasty, nutrient-rich energy bars.

With so many options to choose from, there’s no excuse for not getting the 13 essential vitamins your body needs. As always speak with your doctor about what’s right for you.
