Reasons you may choose not to buy collagen supplements include limited scientific evidence for many advertised benefits, the body's natural protein processing, lack of FDA regulation, potential contamination risks, and high cost.
Collagen supplements are generally made from connective tissue, bones and other parts of cows, pigs, chicken and fish. They can contain toxins and heavy metals that could be harmful. As with all supplements, collagen is not regulated by the Food and Drug Administration (FDA).
Collagen supplements have been investigated as treatment for a host of problems, including aging skin, wound healing, OA, RA, bone health (osteoporosis) and high cholesterol. Most trial results have been at least modestly positive, although some studies lack in quality.
Excess collagen can lead to scar tissue forming and prevent your liver from doing its job of detoxing your body.

The Pros of Collagen Supplements
"At this time, we do not have any strong evidence that any over-the-counter oral or a topical collagen supplement is good for anti-aging," she says.

In some individuals, collagen peptides can cause a slight increase in blood pressure. Those with existing hypertensive conditions should use such supplements with caution. In rare cases, people report an allergic reaction to collagen peptides.
Avoid collagen saboteurs: Sugar and ultra-processed foods (they trigger glycation, damaging existing collagen) Smoking + pollution (oxidative stress = collagen breakdown) Unprotected sun exposure (UVA rays are collagen's worst enemy)
Currently, there are not many known risks associated with taking collagen supplements. However, some supplements are often made with other substances, and if you are allergic to these substances, you may still have an allergic reaction.
