Trends in hair, skin, and nails supplement use: Data from the National Health and Nutrition Examination Survey 2011-2020

Quantity, Duration, Adherence, and Reasons for Dietary Supplement Use among Adults: Results from NHANES 2011–2018

“…Our study revealed that more females than males took dietary supplements for bone health, and healthy skin, hair, and nails, both based on a health professional recommendation and their personal choice. Previous studies have also reported that calcium and biotin intake tended to be higher among females than males [ 29 , 30 , 31 ].…”

Previous research indicated a lower prevalence of melatonin and skin, hair, and nail health supplement use among older adults than in younger individuals [ 31 , 34 ]. Our observations also align with previous studies showing a declining trend in the prevalence of motivations such as more energy, healthy skin, hair, and nails, relaxation, sleep, stress, and weight loss as individuals became older.…”

Vitamins for the Management of Nail Disease: A Literature Review

“…Safe long-term therapies are needed for the management of nail diseases, many of which may be chronic conditions. Despite limited evidence for treatment with vitamins, in a 2008 survey-based study, 66% of dermatologists reported recommending vitamin supplements to patients for purported skin, hair, and nail health benefits [1], and self-reported hair, skin, and nail supplement use nearly doubled from 2.5% in 2011-2012 to 4.9% in 2017-2020 [2]. Therefore, we conducted a literature review on the management of nail disorders, including yellow nail syndrome (YNS), brittle nail syndrome (BNS), onychomycosis, habit-tic nail deformity, periungual/ subungual verruca, and nail psoriasis, with oral, topical, and intralesional vitamins and vitamin derivatives.…”
