What to Look For

Before adding any supplement to your diet, it is important to have a conversation with your health care provider about your individual medical needs. Collagen supplements are generally regarded as safe, but there are side effects, such as digestive issues, associated with them, so a supplement may not be the right choice for you. Additionally, people with dietary restrictions or food allergies should be cautious about which collagen supplement they take.
