Biotin: A Boon for Beauty?
When it comes to approving appearance, some people will try just about anything. With biotin being touted as a booster for hair, skin, and nail health, clients may ask about whether it’s actually effective. In this month’s E-News Exclusive, Today’s Dietitian (TD) delves into the research around supplementing with this vitamin.
After reading the article, visit TD’s website at www.TodaysDietitian.com to read the digital edition of our June/July issue, which includes articles on how the foodservice industry is bouncing back from COVID, disparities in hypertension and kidney disease in pregnancy, malnutrition in cancer patients, and what’s next for agriculture technology.
On another note, thank you to the sponsors, exhibitors, and attendees who made TD’s 9th annual Spring Symposium a rousing success. Look for a recap of the meeting in our August/September issue. We look forward to seeing everyone in Savannah, Georgia, next year.

Biotin Supplementation
Does it really boost hair, skin, and nail health?
By Densie Webb, PhD, RD
Biotin, also known as vitamin B7 or vitamin H (the H comes from Haar und Haut, German for hair and skin), is a water-soluble vitamin that's an essential cofactor for metabolism of fatty acids and amino acids, and for the synthesis of glucose from fatty acids and amino acids. But it's popularly known as a treatment for hair loss and as a way to strengthen nails and improve skin. While there are any number of supplements with names such as Hair Boost, Biotin Beauty Blend, and Hair, Skin & Nails, which leave no doubt as to what they’re formulated for, what are the facts about biotin?
Biotin Research
In the 1980s, biotin supplementation was recommended by the American Academy of Dermatology for hair loss in children.1 But this recommendation was mainly based on case studies and a 1989 German study with dogs, which found significant resolution of hair and skin conditions in 60% of the dogs that were treated with 5 mg biotin/10 kg body weight daily for three to six weeks.2 However, those findings haven't been backed up by any clinical studies and biotin supplementation is no longer routinely recommended for unexplained hair loss. “There is limited current research on the use of biotin supplements for hair, skin, and nails,” says Yasi Ansari, MS, RDN, CSSD, a Los Angeles–based dietitian specializing in sports nutrition, wellness, and eating disorders and a national spokesperson for the Academy of Nutrition and Dietetics.
Biotin Deficiency
While no clinical studies show that biotin supplements will improve hair, skin, and nails in healthy individuals, supplementation is effective at treating hair loss in people with a biotin deficiency, which is rare. In fact, severe biotin deficiency in healthy individuals eating a normal, balanced diet has never been reported.3 Signs of clinical biotin deficiency include skin rashes, hair loss, and brittle nails, which is why biotin supplements are touted for hair, skin, and nails in healthy people.

Link Between Ultraprocessed Food Consumption, Physical Fitness in Kids
A new study found that children ages 3 to 5 who consumed more ultraprocessed foods had poorer locomotor skills than children who consumed less of these foods. It also showed lower cardiovascular fitness in 12- to 15-year-olds who consumed more ultraprocessed foods.
Although previous research has shown that consuming ultraprocessed foods is linked with a higher risk of CVD in adults, this is one of the first studies to show a link between consumption of these foods and lower levels of physical fitness in children.
Ultraprocessed foods were categorized in this study as including packaged snacks, breakfast cereals, candies, soda, sweetened juices and yogurts, canned soups, and prepared foods such as pizza, hot dogs, burgers, and chicken nuggets.
