Collagen is a type of protein found in meats and fish that helps with bone and joint health. It’s also a necessary building block in skin, hair, and nails.

It can help prevent osteoarthritis and improve joint pain symptoms.

Whether you want to increase your collagen intake or are looking for a way to boost your skin, there are many different types of supplements on the market that claim to offer benefits. While some are a scam, others have proven to be effective at helping your body achieve its full potential.

There are a number of side effects associated with collagen supplementation, though they don’t affect everyone the same way. These include changes in your gut, raising calcium levels, and triggering allergic reactions.

Digestive Issues
A number of studies have shown that collagen peptides can help to treat leaky gut syndrome, irritable bowel syndrome, acid reflux, and Crohn’s disease by improving the function of the gastrointestinal tract. It may also improve absorption of water in the intestines, keeping things moving more efficiently through the digestive system.

These benefits are most likely due to the fact that collagen is a natural anti-inflammatory that reduces inflammation and irritation caused by autoimmune disorders, which can lead to more severe GI problems. It can also reduce the inflammatory response to foods that trigger gastrointestinal issues, such as processed and sugary foods.

The biggest downside to taking collagen is that it can throw off the balance of amino acids in your body, which can cause headaches, digestive issues and fatigue. It’s also important to remember that you can become allergic or have an intolerance to collagen, so it is crucial to consult your doctor before you start taking a supplement.

If you’re pregnant or breastfeeding, it’s especially important to consult your doctor before starting a collagen supplement because it can contain hormones that may increase loose skin and stretch marks. It’s also possible to experience digestive side effects if you have certain food allergies, so it’s a good idea to avoid collagen supplements that contain ingredients you are allergic to, such as fish or shellfish.

Choosing Safe Brands
Because there is no regulatory agency that regulates collagen supplements, it’s easy for them to be adulterated and contaminated with toxins and heavy metals. They can also be made from sources that are not naturally rich in collagen, such as cow, pig or chicken bones and tissue, which can be harmful.

For example, shark cartilage has been linked to high calcium levels, which can lead to hypercalcemia, a condition that can result in abnormal heart rhythms and bone pain. This side effect is more likely to occur if you have a history of calcium oxalate kidney stones, according to the National Library of Medicine (NLM).

It’s also a good idea to make sure you’re not allergic to collagen, as some supplements can be contaminated with common food allergens like fish, shellfish or eggs. Some people also report nausea and bloating from collagen, but these are very mild.
