MD1003 (High-Dose Pharmaceutical-Grade Biotin) for the Treatment of Chronic Visual Loss Related to Optic Neuritis in Multiple Sclerosis: A Randomized, Double-Blind, Placebo-Controlled Study.
This randomized, double-blind, placebo-controlled study evaluated the effect of MD1003 (high-dose pharmaceutical-grade biotin) on vision in MS patients with chronic visual loss. The study did not meet its primary endpoint, as the mean change in visual acuity was nonsignificantly larger with MD1003 than with placebo. An interesting trend favoring MD1003 was observed in the subgroup of patients with progressive optic neuropathy.
MD1003 (high-dose biotin) for the treatment of progressive multiple sclerosis: A randomised, double-blind, placebo-controlled study.
RCT of 154 patients with progressive multiple sclerosis comparing high-dose biotin (MD1003) to placebo over 12 months. 12.6% of MD1003-treated patients achieved disability reversal, with reduced EDSS progression and improved clinical impression of change compared to placebo. Efficacy was maintained, and the safety profile was similar to placebo.
Pregnancy and lactation alter biomarkers of biotin metabolism in women consuming a controlled diet.
The study measured biotin biomarkers in pregnant, lactating, and control women consuming a controlled diet with 57 μg of dietary biotin/d. Pregnant women showed increased excretion of 3-HIA, while lactating women showed increased excretion of bisnorbiotin, indicating altered biotin metabolism during these reproductive states. The findings suggest that biotin intakes exceeding current recommendations may be needed during pregnancy and lactation.
Supplementary biotin decreases tibial bone weight, density and strength in riboflavin-deficient starter diets for turkey poults.
The study investigated the effects of different dietary concentrations of riboflavin and biotin on growth and skeletal responses in turkey poults. Supplementary biotin in riboflavin-deficient diets was associated with decreased tibia weight, density, strength, and stiffness, indicating negative effects on bone health.
Effect of biotin supplementation in infant formula: A multi-center study in Japan.
This non-randomized intervention study evaluated the effect of biotin supplementation in infant formula on biotin metabolism and development in 84 healthy Japanese infants. Formula B-fed infants had higher urinary biotin concentrations than Formula A-fed and breast-fed infants at 1 and 6 months. ASQ scores were similar across groups from 9 to 36 months. The study supports the use of biotin in infant formula.
Serum biotin interference: A troublemaker in hormone immunoassays.
The study investigates biotin's interference on 25-hydroxy vitamin D, parathyroid hormone, and thyroid-stimulating hormone tests using different assay systems.
