Biotin 101: Forms, Uses, and Correct Dosage

Posted By Lovella Sitoy in Rapunzel on Feb 08, 2016

Biotin, or vitamin B7, is one of the essential B complex vitamins. A water soluble nutrient that is naturally produced by bacteria in our gut. Apart from the gut-synthesized biotin, dietary or supplementary biotin is also well-absorbed by our body. And since it is water-soluble, excess biotin goes out of the body through urination. 

Uses of biotin

1. Biotin therapy helps improve brittle and thin toenails and fingernails
2. It also increases rate of hair growth and strengthens hair strands
3. Biotin therapy has been used in reversing alopecia in adults and children

In as many as 50% of pregnant women may also experience biotin deficiency. Thus, some women may experience some form of hair loss after giving birth. Giving them a multivitamin containing biotin can help combat this deficiency.

Biotin supplements have also been used for improving glucose levels and reducing nerve damage in diabetes patients. Biotin injections may also be a good treatment for cradle cap (Seborrheic Dermatitis).

Available forms of biotin

We can buy oral biotin supplements in either tablet, soft gel capsule, or in sublingual or liquid forms. Some people may find it difficult to swallow a pill or big capsules. In which case, taking a liquid supplement is a very convenient option. With a liquid form of biotin, we can easily incorporate it in our daily drink. Apart from ease of swallowing, studies also suggest that liquid supplements have a faster rate of absorption.

Rapunzel Liquid Biotin is a sweet-tasting, easy-to-ingest biotin supplement to help strengthen your hair and nails. It is a quality formulation that’s clinically designed for faster absorption rate and higher potency and efficiency compared to regular biotin caps or pills.

It is fun and enjoyable to take. By simply adding two droppers full of liquid biotin to our morning smoothies or water, we can be assured of better hair in no time. For thicker, faster-growing locks, take a good biotin supplement everyday. 

Current Recommended Daily Intake (RDI) of Biotin (micrograms)

  • Adults - 300 mcg
  • Children 11 and up - 30 to 300 mcg
  • Children below 11 years old - 30 mcg
  • Infants - 10 to 15 mcg

Caution: It is very important to consult a health professional when administering biotin supplement in infants and children.
