Vitamin B is commonly confused with other forms of nutrients. That’s because “vitamin B,” is a term that actually refers to a group of vitamins known as the B complex.
B complex vitamins (vitamin B) includes 8 compounds:
- Vitamin B1 (thiamine)
- B2 (riboflavin)
- B3 (niacin)
- B5 (pantothenic acid)
- B6, B7 (biotin)
- B12 along with folic acid.
While each of the B complex vitamins are important for different uses in the body, their main purpose is to provide your body with essential energy from the foods and beverages you eat.
However, vitamin B3 or niacin offers a unique set of health benefits. Here are just a few of the most notable:
- Cholesterol balance
- Skin clarity
- Blood sugar support
- Supports insulin sensitivity
- Reduced risk of stroke and CVD
Getting Enough Vitamin B3 into Your Diet
Your standard everyday diet may not include the daily value of 20 mg of vitamin B3 (more closely 16 mg for men 14+ years of age and 14 mg for women ages 14 and up). 
Without enough B complex vitamins, you may suffer from any of these deficiency symptoms:
- Circulatory problems
- Brain fog
- Dry skin
- Anxiety and poor mood

How-to Make Smoothies with Niacin Sources
All you need to make superfood smoothies packed with vitamin B3 a blender and your choice of liquids. Here is a sample recipe for you to start with:
Energy Booster Niacin Smoothie Ingredients:
- 1 cup frozen berries (blueberries, strawberries, blackberries)
- 1 ripened banana
- ¼ cup peanut butter
- 1 scoop pea protein powder
- 1 cup milk or milk substitute
- Water to thin

Consuming a fresh smoothie made with foods high in niacin delivers a good source of B3 right into your bloodstream. Because of the liquid consistency of smoothies, they are more quickly converted into energy inside the body and thus offer a more rapid burst of energy than eating solid foods with niacin.
More About Niacin
Niacin is a water-soluble vitamin, meaning that your body does not hold onto it or store vitamin B3 inside tissues.
In fact, it is eliminated via the kidneys and bladder through urination. For this reason, you need to eat foods with niacin every day and at varying times throughout the day to maintain your energy levels, lean waistline and overall health.
However, it is very important that you talk to your doctor before adding a regular dosage of niacin to your regimen. High doses of niacin are known to cause flushing of the skin due to the ability of B3 to increase circulation. Known as a “niacin flush,” this response is common but it can be painful for some people and even cause liver or digestive problems.
