Vitamin C, also known as ascorbic acid, is a water soluble vitamin. It is a potent antioxidant that plays many vital roles in the body, including immunity support, brain function and tissue formation.*

Vitamin C is one of the top go-to supplements for immune system support, especially when trying to combat the common cold. As an antioxidant, vitamin c helps to block the destruction of free radicals, which are known to cause damage to our DNA. Over time this damage can weaken the immune system and contribute to the aging process, leaving us more susceptible to disease formation.*

Normal brain function relies on vitamin C for the production of certain neurotransmitters that send signals which trigger thoughts, emotions, and commands to other parts of the body.*

Additionally, cardiovascular health can be attributed to adequate vitamin c intake. Vitamin C is thought to be helpful in protecting the arteries from damage by keeping the arteries flexible and not hardened by plaque build-up.*

Vitamin C plays an important role in body structure and the tissues that hold us together. Collagen, the protein framework of our skin and bones, relies on the presence of vitamin C, which is a co-factor in its formation. Collagen can also be found in other connective tissues—cartilage, tendons, and ligaments. Vitamin C also aids in repairing these tissues after trauma has been sustained from injury or surgery.*
