The popularity of supplements promising enhanced physical appearance has seen a significant surge, with reports indicating a doubling in the proportion of Americans using hair, skin, and nail vitamins from 2011 to 2020, as per CNBC Make It.
However, experts are now sounding the alarm about potential risks and hazards associated with these beauty supplements. Many of these products contain excessive amounts of biotin, a B-vitamin often associated with hair and nail health. A study published in the Journal of the American Academy of Dermatology sheds light on the dangers of such excessive biotin consumption.
Dr. Rebecca Hartman, an assistant professor of dermatology at Harvard Medical School and one of the authors of the study, warns that an overabundance of biotin “can affect test results that healthcare providers may order, like thyroid testing, cardiac testing [and] potentially even vitamin D testing.”
While the recommended daily dose of biotin for adults is 0.03 milligrams, some supplement capsules pack a staggering 650 times that dose, an alarming discrepancy highlighted by the US Food and Drug Administration.
The consequences of such high biotin doses can be severe. They might lead to inaccurate diagnoses of hyperthyroidism and even hinder the detection of heart attacks, according to Dr. Adam Friedman, dermatology chair at George Washington University. He stresses the gravity of the issue, pointing out that there have been instances where missed heart attack signs, caused by elevated biotin levels, have resulted in fatalities.
Biotin deficiency is an extremely rare occurrence, and experts like Friedman emphasize that genuine deficiencies would likely require medical intervention rather than reliance on biotin supplementation from stores.
For nutrients like biotin and collagen, often touted for their beauty benefits, experts emphasize the importance of a well-rounded diet. While potential benefits of collagen for skin health are suggested, research findings remain inconclusive, according to Dr. Hartman.
Biotin-rich foods like egg yolks, nuts, beans, and seeds are already part of a balanced diet. Collagen can be sourced from meats, bone broth, gelatin, dairy, beans, soy, as well as vitamin C, zinc, and copper-rich foods like fruits, leafy greens, and root vegetables, all of which contribute to collagen production.
Before considering beauty supplements for hair, skin, and nails, experts advise individuals to consider several crucial factors:
Does the supplement genuinely contain the claimed active ingredients?
Is there credible evidence supporting the specified dosage?
Is the manufacturer reputable and transparent?
Has the product undergone third-party testing for contaminants?
Have I consulted a healthcare professional before making this decision?
Dermatologists also urge caution when it comes to collagen supplements, as some products might contain harmful metals.
In conclusion, Dr. Friedman and other experts discourage the use of biotin supplements due to the potential risks outweighing the rewards. Instead, they advocate for a holistic approach that prioritizes a balanced diet and consultation with healthcare professionals for any supplementation decisions.
