Are collagen supplements safe?
More research needs to be done to understand the negative side effects of collagen. Some studies show that collagen supplements may lead to:
- Bad taste in the mouth
- Heartburn
- Feeling of fullness
Collagen supplements are not controlled by the FDA. So its safety and effectiveness are not 100 percent guaranteed. You may find it difficult to know the components of collagen supplements. According to studies, some components of collagen supplements include:
- Heavy metals (like cadmium)
- Microbial contaminants
- Allergens (like hydrolyzed collagen from fish)
Some supplements may contain ingredients that are not on the label.
Experts advise people to buy products that have a USP verified mark on the label. Products with this mark:
- Contains the ingredients listed on the label
- Doesn’t have toxic substances
- Can be degraded and absorbed by the body in a short period.
- Has been made according to the FDA’s Current Good Manufacturing Practices (CGMPs)
It is important to talk with your doctor before using any supplement if you:
- Have a chronic disease
- Are allergic to fish
- Are taking prescription medication
- Are taking other dietary supplements
Your healthcare provider will tell you if a supplement is safe. It would help to take supplements without any fish ingredients, if you have fish allergies.
