水解膠原蛋白是靈丹妙藥嗎?

Can relieve joint pain

Because joint cartilage contains collagen, and joint pain is often caused by the loss of collagen, it is thought that collagen can reduce joint pain.

Research shows that hydrolyzed collagen (or collagen hydrolyzate) can help strengthen joints and relieve pain from conditions like osteoarthritis.

However, keep in mind that most studies showing that consuming collagen improves joint pain have used high-dose collagen hydrolyzate supplements .

It's unclear whether simply increasing dietary intake of collagen-rich foods would have the same effect.

Can treat osteoporosis

While research is still in its early stages, a 2010 study suggests that hydrolyzed collagen may play a role in preventing and treating osteoporosis.

A 2018 study in postmenopausal women found that treatment with 5 grams of collagen peptide daily for a year increased bone mineral density and improved markers showing increased bone formation and decreased bone degradation.

More research is needed to determine whether other forms of collagen sources may also be helpful.

Helps repair wrinkles

Your skin is made of collagen, so it makes sense that collagen supplements can heal your skin. The effectiveness of a product depends on how the collagen is made and how the body uses it.

Some research suggests that taking collagen supplements may benefit the skin by reducing certain signs of aging.

A 2018 Trusted Source study involving 64 participants found that treatment with 1 gram of collagen peptides for 12 weeks significantly reduced wrinkles and improved skin hydration and elasticity compared to a placebo group.

The U.S. Food and Drug Administration (FDA) has also approved the use of collagen implants to smooth wrinkles and treat acne scars.

There are other claims that collagen can be used in skin creams to improve skin structure, but they are not supported by research.

Safety first

The FDA has recalled several products containing hydrolyzed collagen because manufacturers made false claims about their efficacy. Sometimes, the fix promised by the label actually requires medical attention, the FDA said in a 2014 statement.

As with any supplement or cosmetic, you should always read the claims carefully. The FDA regulates these products and can take action against companies that make false claims or misbrand products.
