Amongst these so-called surprise tablets are ones touting biotin and collagen to enhance your pores and skin and nails.
You might be questioning concerning the distinction between the 2 and whether or not you have to be taking them alone, collectively, or in any respect. Right here, two consultants break it down.
What’s biotin, and what are its advantages?
?
Biotin sounds fancy, but it surely’s actually simply one other time period for vitamin B7.
In line with Rajani Katta, MD, a Houston-based dermatologist and writer of Glow: The Dermatologist’s Information to a Complete Meals Youthful Pores and skin Weight loss plan, individuals who take sure antiepileptic medicines could develop a biotin deficiency. Consuming quite a lot of uncooked eggs can even trigger a biotin deficiency as a result of avidin, a protein present in uncooked egg whites, binds to biotin, so it isn’t absorbed by the physique.
“There are genetic causes of biotin deficiencies, and this can lead to hair loss; red, flaky rashes on the skin; and brittle nails,” she says. “Other factors that might lead to lower levels of biotin are smoking, excessive alcohol intake, and pregnancy.”
As a result of biotin will be produced by micro organism within the intestines, some individuals who have situations that have an effect on the micro organism of their intestines may develop a deficiency, Dr. Katta says. Inflammatory bowel illness, small intestinal bacterial overgrowth, and different situations would possibly have an effect on the steadiness of microbes within the intestines and thus could improve your danger of biotin deficiency.
The truth that biotin deficiencies typically result in hair loss, pores and skin rashes, and different issues could also be why producers started including it to pores and skin, hair, and nail dietary supplements, says Dr. Katta. “However—and this is a really important point—in the years since, we just haven’t had strong evidence that biotin can help strengthen skin, hair, or nails in the absence of a deficiency,” she says.
In case you are poor, you may get extra biotin by way of the weight loss program. Dr. Katta recommends rising your consumption of biotin-rich meals, together with egg yolks, nuts and seeds, and candy potatoes, in addition to salmon, lean meat, and organ meats resembling liver.

There may be little proof that supplementing biotin may also help in the event you don’t have a deficiency, says Dr. Katta. Except you might be poor, she doesn’t advocate taking further biotin.
“There have been a few very small studies indicating improvement in brittle nails, but, importantly, we do not know these patients’ baseline biotin status, and the studies did not include a placebo group,” she says. All of that signifies the examine wasn’t tremendous prime quality.
It’s additionally vital to be conscious of potential unwanted side effects, the largest one being that giant doses of supplemental biotin can intervene with medical lab exams, resembling exams for thyroid values and exams for coronary heart assaults, Dr. Katta says.
“Apart from that, extra biotin does not seem to cause side effects in most people, although some people have reported digestive upset,” she says. “However, we also don’t understand exactly how large doses affect insulin function and blood sugar levels in different people, so that is an area that definitely needs further research.”

What’s collagen, and what advantages does it provide?
?
You’ve in all probability heard of collagen. It’s the protein accountable for cushioning your joints, plumping your pores and skin, and providing you with stronger bones, hair, and nails—and extra.
Right here’s the way it works: Once you eat, your physique breaks down the protein in your meals into amino acids. These are the constructing blocks of protein, and when mixed with vitamin C, copper, and zinc, they create collagen. You’ll discover it in your physique’s connective tissue and its extracellular matrix—primarily a community that provides structural assist to tissues.
Most collagen within the physique is kind I, II, and III. “Type I collagen is present in most connective tissues with bone, ligaments, tendon, and skin,” says Amy Gorin, a registered dietitian nutritionist and proprietor of Plant-Based mostly Eats in Stamford, Connecticut. “Type II collagen is found mostly in cartilage, and type III collagen is found in the skin, lungs, the walls of blood vessels, and intestinal walls.”
Meals sources of collagen embrace bone broth and meat that comprises connective tissue, Gorin says. You too can purchase collagen dietary supplements—tablets, powders, even collagen-containing meals—in shops.
So, why the sudden inflow of collagen dietary supplements? “Collagen is a very important structural protein that helps provide scaffolding and support to your skin, and as you age, your collagen starts to break down and your body doesn’t produce it at the same rate,” Dr. Katta says. “This is one of the reasons that manufacturers started putting it in supplements—there’s a hope that if you eat it, your body can use it to make new collagen.”

We all know all the nice issues our pure collagen does, but it surely’s not clear whether or not supplemental collagen can have the identical advantages. Analysis remains to be preliminary.
One huge unknown is whether or not your physique would use protein’s amino acid constructing blocks to particularly make new pores and skin collagen. “Some of those building blocks do seem to make their way to the skin, but it’s hard to say if consuming them in the form of a supplement is any better than consuming them from foods,” Dr. Katta says.
Different researchers have checked out collagen dietary supplements from one other angle, asking whether or not the pores and skin seems higher after taking collagen dietary supplements, Dr. Katta says.
“With the research that’s been done so far, they all raise more questions in my mind,” she says. “Many of the research studies have been sponsored by the manufacturer or have lacked a placebo group, which is just not ideal.”
Take, as an illustration, a examine revealed in 2018 in Diet Analysis. Researchers discovered that collagen supplementation could also be useful for pores and skin elasticity. Large caveat: the researchers work for an organization that makes collagen dietary supplements.
Some research have used a placebo group, however they haven’t checked out wrinkles, Dr. Katta says. As a substitute, they’ve checked out different outcomes, resembling pores and skin moisture ranges. As a result of there are meals that will obtain the identical profit, researchers don’t have sufficient proof to say that dietary supplements might present any profit. In spite of everything, chances are you’ll already get every part you want out of your weight loss program.
“A common issue is that when my patients ask me about supplements, they’re hoping that it will help with skin wrinkling, not just skin moisture,” Dr. Katta says. “Of the collagen research done, hardly any has looked at wrinkling.”
Contemplating the restricted analysis, is it price it to shell out cash for collagen dietary supplements? “I tell my patients that when it comes to collagen supplements, their guess is as good as mine,” D. Katta says. “The research that has been done hasn’t been that strong.”
Though animal collagen merchandise could present amino acid constructing blocks that your physique can use to create new proteins, Dr. Katta prefers to get these amino acids from high-quality meals sources. Rooster, beef, fish, and eggs are all nice sources.
Are collagen dietary supplements protected?
?
A standard false impression Dr. Katta encounters together with her sufferers is that they consider collagen dietary supplements aren’t dangerous in any respect. They assume there’s no hurt in taking them, even when they don’t truly work.
“I tell my patients that that’s not true: some supplements can be risky,” she says. “There is no FDA [Food and Drug Administration] approval needed for supplements, and there’s no required quality control.”
In truth, the unbiased lab ConsumerLab, examined 15 totally different collagen dietary supplements and located that one was contaminated with the heavy steel cadmium. Heavy metals resembling lead, mercury, arsenic, and cadmium are regarding as a result of they’ll trigger severe well being results.
“Many of my patients are really careful when they consume seafood, seeking out only low-mercury fish, but they often don’t realize that there’s limited oversight of the supplement industry,” Dr. Katta says. “In fact, many collagen supplements don’t even disclose which animals they use to source their collagen, let alone how they’re ensuring the quality of those sources.”

Biotin and collagen aren’t simply bought as tablets and powders. You’ve in all probability even come throughout shampoo, conditioner, and different hair merchandise touting biotin and collagen as their lively elements to advertise lengthy, thick, and voluminous hair.
Don’t be fooled by the advertising and marketing lingo. These aren’t holy-grail merchandise.
“I’ve seen even less research on topical application of these products, and collagen is such a large molecule, so I wouldn’t expect it to be absorbed through the hair or skin and thus wouldn’t recommend it either for hair products,” she says.
