If a nutrient deficiency is suspected as the cause of your brittle nails, a doctor like DR. MANNING might first recommend dietary adjustments. However, if a doctor approves supplement use, research suggests certain supplements could offer benefits for nail health.

The Role of Biotin

Biotin supplements are often considered for brittle nails due to biotin‘s crucial role in keratin production,the protein that forms nails. One study indicated that 63 percent of participants with brittle nails experienced improvements after taking a daily biotin supplement. A more recent review also suggested that biotin supplementation, alongside increased intake of other micronutrients, could be beneficial.

“In my experience, it’s safe to try a moderate dose of biotin short-term, notably if we’ve ruled out more serious causes like iron or thyroid issues,”

However, it’s important to note that studies supporting biotin’s effectiveness are generally small and of lower quality, necessitating further research to establish a definitive link.

Collagen’s Potential Benefits

Research indicates that supplementing with “bioactive collagen peptides” may also improve brittle nails,with 64 percent of study participants reporting positive changes. Collagen, a protein, is known to strengthen skin, muscles, and bones.

“Collagen is made of amino acids that help form keratin, so it makes sense biologically,” says CRISTINA DEL TORO BADESSA, MD, a board-certified physician with Artisan, a plastic surgery practice in ATLANTA. “I often suggest it as part of a holistic nail health plan, especially since it may also benefit skin and joint health.It’s not a guaranteed fix, but it’s safe, and many of my patients do report stronger nails after a few months.”

Despite potential benefits, it remains unclear weather biotin supplements can truly strengthen brittle nails, especially without an existing deficiency.

Before starting any supplement, consulting with a healthcare professional is crucial.

“In my experience,it’s safe to try a moderate dose of biotin short-term,particularly if we’ve ruled out more serious causes like iron or thyroid issues,” says DR.DEL TORO BADESSA. “I also remind patients to let their doctor know if they’re taking it,since high-dose biotin can interfere with lab tests,including thyroid and cardiac markers.”
