Vitamin C Oranges

 

Vitamin C 

This important vitamin is vital for our bodies. We cannot make or store vitamin C. Therefore, we need to take organic vitamin C regularly. This keeps our levels up throughout the day.

Vitamin C helps form our skin and mucous membranes, which are the body’s first line of defense. It also helps regulate immune cells. This is important for fighting off harmful bacteria and viruses. Because of this, vitamin C is essential for a healthy immune system.

Many citrus fruits contain a good source of vitamin C. Organic superfood powders have a lot of it. Examples include baobab, camu camu, and acerola. Vitamin C is also present in the healthy oil, like sea buckthorn.

Boosting your diet with vitamin C charged supplements throughout the day keeps your cells saturated, so your immune system can work at its best. To guarantee you're receiving sufficient vitamin C, you can easily begin your morning with a vitamin C supplement.

Vitamin D

Vitamin D is both a nutrient we eat and a hormone our bodies make. This fat-soluble vitamin has long helped the body absorb and retain calcium and phosphorus. Both of these play a critical function for building bone.

Also, some studies have shown that vitamin D can reduce cancer cell growth, help control infections and reduce inflammation. A deficiency in vitamin D increases autoimmunity and raises susceptibility to infection.

Maintaining optimal vitamin D levels is essential. This is to support a healthy immune response and promoting the proper functioning of white blood cells. They play a critical role in defending the body against infections.

Research shows that getting the right amount of vitamin D and fatty acids can reduce inflammation in the body. This results in reducing the risk of heart disease and other chronic health conditions."

Few foods naturally contain vitamin D, though some manufacturers fortify foods with the vitamin. If you are lucky enough to be able to enjoy the sunshine daily, you are on the right path. For others, the best way to take a vitamin D supplement because it is hard to eat enough through food.
