When the season changes into swinging weather patterns and colder, rainier days, it's time to start giving ourselves some extra immunity-boosting love. Here are three of our top vitamin picks—and foods packing them—for staying healthy and getting proactive about prevention during cold and flu season. We're also highlighting a few of our smoothies that are great go-to blends to help you get your vitamins easily.

Vitamin C
This vitamin is one of the biggest immune system boosters that can help fight off illness. Daily intake of vitamin C is essential because our bodies don't produce or store it. Foods rich in C include citrus fruits (e.g., lemons, oranges), berries, peppers, spinach, kale & broccoli. 
Another reason to love vitamin C is that it helps with the absorption of plant-based iron, which is boosted when paired with a source of vitamin C. Check out the blends below that are high in vitamin C and Iron.

Vitamin E
This vitamin is a powerful antioxidant that helps the body fight off infection. It also supports vision, reproduction, and health of your blood, muscles, brain and skin. 
Natural ingredient sources containing vitamin E are the best choice. Some of the foods rich in vitamin E include wheat germ oil, almonds, peanuts, leafy greens and avocado. If you take a supplement, it may not offer the same benefits and, in some cases, can be dangerous to your health. 

This vitamin is important for keeping your nervous and immune systems healthy. Deficiency in vitamin B6 can cause anemia, dermatitis, depression, and a weakened immune system. Some of the food sources of vitamin B-6 include spinach, chickpeas, sweet potatoes, avocado, salmon, tuna, poultry, some nuts, and bananas. 
A vitamin B6 deficiency is usually coupled with deficiencies in other B vitamins, such as folate (vitamin B9) and vitamin B12. The recommended daily amount of vitamin B6 for adults is 1.3 milligrams. Our fave Vitamin B containing blends are highlighted below.
