The term "Vegan" is used to describe the practice of abstaining from the use of animal products—especially in the diet. Veganism can be also associated with a philosophy of life and religious beliefs. Those who choose to adhere to veganism often decide to do so for ethical and environmental reasons. 

A whole-food vegan diet is regarded as healthier as it is free from cholesterol and typically higher in fibre and lower in various toxins than an omnivorous diet. Numerous studies found that a strictly plant-based and unrefined diet significantly lowers the risk of various health problems. 

Vegans avoid not only animal foods but also nutritional supplements that contain ingredients derived from animal sources. A Vegan supplement is one made without any animal byproducts. Majority of the HealthAid® products are suitable for Vegans and Vegetarians.
