Ingestible collagen is gaining popularity due to its potential benefits for skin, hair, nails, and overall body health. However, there is limited scientific research on collagen supplements, and the amount needed for optimal results is still being determined. Experts recommend looking for hydrolyzed, third-party tested products containing collagen types I and III. While collagen can be found in certain foods like bone broth and red meat, supplements provide a concentrated source that may be easier for the body to absorb. It’s crucial to follow manufacturer’s instructions and be cautious of potential side effects like headaches and stomach upset.
