Vitamin C is a water-soluble vitamin with a role in the formation of collagen, which is an important constituent of bones, muscle, cartilage, and blood vessels. This vitamin is not stored in the body well and some of the main sources of Vitamin C include fruits and vegetables. High-quality supplements, such as Deva Vegan Vitamin C products are other potent sources of Vitamin C. Our Vegan Vitamin C Multi-Source product is made from amla fruit, acerola cherry, fermentation-based vit c, camu camu, and rosehips. Each tablet provides 250 mg of Vitamin C as well as various phytonutrients from multiple plant sources. Amla fruit aka Indian Gooseberry is a bitter-tasting edible fruit commonly harvested and consumed in India. It is also used in many traditional Ayurvedic herbal preparations. Acerola Extract is derived from the fruit of the Acerola plant also known as West Indian Cherry. The fruits of the acerola tree are appreciated for their nutritive value, and they are generally regarded as being one of the richest food sources for vitamin C in the world. Camu Camu is also a shrub-like Acerola, found in the Amazon forest and known as a potent source of vitamin C. Rose hips are berries, which can be eaten fresh, dried, or even preserved. They are known for their high content of Vitamin C as well. Our Vitamin C is buffered with calcium so its acidity is reduced in the stomach. This helps so that it may be easier on your stomach and less likely to cause loose stools. DEVA Vegan Vitamin C is 100% animal-free and guaranteed for purity, freshness, and labeled potency. Remember all DEVA Products are 100% vegan, vegetarian and are registered by the Vegan Society, the non-profit organization that actually invented the word "vegan".
