Once-daily vitamin supplement that stimulate epidermal cells and strengthen keratin, the protein found in nails.

TheraNail-TF is a proprietary formulation containing Biotin (2.5 mg), Iron (10 mg), and Zinc (10 mg) available for oral administration as a small, once-daily, easy-to-swallow tablet.

  • As a dietary supplement, take 1 tablet once daily or as directed by a physician.
  • Do not exceed the Recommended Daily Allowance (RDA).

Product Attributes:

  • Increase nail strength
  • Reduce nail breakage
  • Improve nail structure
  • Smooth brittle ridges

Each TheraNail-TF TABLETS contains 2.5 mg of biotin, a dose clinically proven to improve nail strength and quality. Biotin is a water-soluble component of the Vitamin B complex.

As an essential nutrient, biotin:

  • Acts as a coenzyme for the body’s carboxylation reactions and is a factor in maintaining healthy nails
  • Increases the keratin matrix proteins in the nail, thereby improving keratin structure

The additional benefits from 10 mg of iron and 10 mg of zinc make TheraNail-TF the Total Formulation for weak and brittle nails. • Low levels of Iron and Zinc can cause brittle nails (NIH)

Clinical Studies:

  • Clinical studies have demonstrated that a daily intake of 2.5 mg of biotin, the amount found in TheraNail-TF, can indeed strengthen and improve the quality of brittle nails. Over time, TheraNail-TF will transform nails naturally from the inside out—producing strong nails. One study found that 91% of individuals suffering from brittle nails experienced an improvement in nail quality after just 5 months of taking 2.5 mg of biotin daily.
  • Store in cool, dry place.
