With all the protein powders, hair vitamins, and other dietary supplements on the market, it's often hard to keep up. Collagen powders, in particular, have skyrocketed in popularity in recent years, promising to give customers flowing hair, healthy nails, and supple skin when used in tandem with other high-quality maintenance products, like moisturizers, serums, oils, and shampoos and conditioners. But what do collagen powders really do—and are they worth all the hype?

First and foremost, it's important to understand what collagen is and what kind of role it plays in fostering healthy hair, skin, and nails. Per the National Library of Medicine, collagen is a protein that makes up the structure of many of our cells and tissues. Found in connective tissues, tendons, bones, cartilage, and skin, it aids in immune response, tissue repair, and other essential cellular functions. 

"By age 30, our bodies begin to lose collagen and continue to produce less each year, with production diminishing significantly by the age of 50," notes Nutrafol's Vice President of Product Marketing & Innovation Sam Archer. In regards to hair health, Archer adds: "Our scalps are made up of 75 percent collagen. As we age, the loss of collagen and elastin means that we can no longer hold onto strong hair at its foundation and hair becomes weaker. This can result in hair thinning and loss."

Enter collagen powders, the purported solution to thinning hair, alongside newfound hair and skin health. But the cure for hair thinning, at least, isn't so simple: Archer says, "Collagen peptides can replenish collagen within our bodies, however collagen peptides cannot improve hair growth on its own—which is a common misconception."

Does Collagen Powder Work?

"The evidence is conflicting regarding the effectiveness of collagen powders, and whether or not they work is still up for debate," admits Peter Young, M.D., dermatologist and medical director of skincare company Facet. "There are very few scientific studies on collagen powder, and many of them have come back with mixed results. The theory behind collagen powders is that they can improve and boost our body’s collagen and collagen production, resulting in anti-aging benefits, reduction in fine lines and wrinkles, and improvement in skin hydration and elasticity."

However, many people (including me) use collagen powder and find that it produces satisfactory results. "Collagen is a protein known for being a key component in building and repairing bone, muscles, skin (including your scalp), and, yes, hair," explains Ashanti Lation, celebrity hairstylist and founder/CEO of VIP Luxury Hair Care. Furthermore, she explains that she recommends collagen powder to her clients "after childbirth, surgery or any major changes in diet or hormone levels, because these changes can lead to thinning or shedding. Collagen can provide the protein needed to strengthen the hair and lower estrogen levels."

What To Look For in Collagen Powders

As with all food and beverage items you consume, you be aware of what should be―and what shouldn't be―in your collagen powder. Archer says, "Buyers should be on the lookout for naturally efficacious ingredients in their collagen powders, as well as sustainably sourced ingredients." However, she points out that, unfortunately for vegans, "collagen peptides cannot be vegan—collagen can only be made by animals, not plants."

Dr. Young agrees, saying, "Most collagen powders originate from animal sources such as cows, pigs, and fish (“marine collagen”). Hydrolyzed collagens in which the amino acids have been broken down, are easier for your body to absorb. Look for collagen powders with a diverse amino acid profile."

And which amino acid profiles are these? "Bovine (cow) and porcine (pig) sources of collagen powder are best," he says. "You should avoid marine collagen because 'marine' is a blanket term for any aquatic animal, including shellfish, shark and jellyfish, and you never know what you’re getting. These sources of collagen are not easily absorbed by the body." 

When it comes to other ingredients you should avoid, Dr. Young advises staying away from artificial colors, flavors, and sweeteners.

How Do You Use Collagen Powder?

Once you have your collagen powder of choice, you may wonder what to do with it. Luckily, it's a versatile, easy-to-use supplement, and it takes just a few seconds to incorporate into your breakfast routine. 

"Most collagen powders are formulated to mix with a liquid—whether it be water, tea or coffee—to drink once a day. However, serving sizes can vary from brand to brand," says Archer. So pay attention to what the packaging says! Personally, I like mixing my collagen powder into my morning coffee, and I keep the container next to my coffee machine so that I never forget about it. Archer also suggests, "You can also add it to food that contains some water content to help it dissolve, like yogurt, soup, or a smoothie."

Lation adds, "I personally love smoothies, but I’ve seen people add it to their juice mixtures, and even bake with it."

Side Effects

Our experts all agree that before trying collagen powder, it may be best to consult your doctor about whether its ingredients make it a good option for you, particularly if you have preexisting health conditions. And, of course, if you start experiencing troubling symptoms or side effects after starting to use collagen powder, you should stop and consult your doctor.

"Most studies demonstrate collagen powders to be safe to use. The most common side effects are heartburn and stomach bloating," reassures Dr. Young. Some users also complain of skin "purging" after beginning use, meaning that the increase in collagen intake causes some breakouts. For me, these cleared in about a week.

Dr. Young also warns, "Collagen powders should be avoided in people who have a history of or high risk of developing kidney stones. However, consuming collagen in moderation as part of a normal healthy diet is unlikely to cause kidney stones in the vast majority of people."

Finally, Archer points out that women who are nursing or pregnant should consult with their healthcare providers before using collagen powders, as they have not been tested rigorously enough among that population.
