Custom Health Guide


We prefer this brand because…...

We look for biotin to be in a large enough dose to be effective, and this brand with 8,000mcg. per capsule is ideal. We also seek the best absorption, and this Thorne formula is made without flowing agents that can inhibit bioavailability. It also free of lubricants and diluents, and free of magnesium stearate or preservatives which could also bind up the biotin and impede its absorption. Our patients have reported noticeable improvements in nail resilience and growth, and we have seen success with including biotin in blood sugar balancing protocols.

About biotin

Biotin is an essential water-soluble B vitamin, also known as vitamin B7. It is found in small amounts in legumes, fish and cruciferous vegetables. Biotin works as a coenzyme for major enzymes that participate the release of glucose into the blood stream to be metabolized for energy. Biotin is also essential for the metabolism of several key amino acids including isoleucine, valine and methionine, and it helps regulate gene expression. Biotin may reduce total cholesterol and “bad” LDL-cholesterol, and may help boost “good” HDL-cholesterol and aid in the manufacture of important fatty acids. Biotin also supports healthy immune function: both white cell function and antibody production.

For blood sugar, high doses of biotin encourage insulin secretion from beta cells in the pancreas; enhancemuscle insulin sensitivity by increasing glucose uptake by muscle cells; and by accelerating glucose breakdown or storage in the liver. Biotin used with chromium helps glycemic control in type 2 diabetes, reducing the total duration of high blood glucose in a two-hour glucose tolerance test. Biotin stimulates expression of the genes that oversee insulin, insulin receptors, pancreatic glucokinase, and hepatic glucokinase genes, all of which encourage a better insulin response and lower blood sugar levels, and fosters more efficientmovement of glucose into cells.

For nails, clinical trials with patients with brittle fingernails received biotin for several months: ninety-one percent showed "definite improvement," exhibiting firmer, harder fingernails. Biotin increased nail thickness, reduced splitting, and made the irregular dorsal surface of the nails more regular. Another study showed that biotin supplementation resulted in a 25% increase in nail thickness in approximately 63% of subjects with brittle nail syndrome.
