Buying guide and FAQs
What to compare
Strengths range widely, and many imported products are measured in thousands of micrograms. Compare the biotin per serving and check what else is in a blend. Gummies are the largest group, followed by capsules, softgels and tablets.
How much biotin is too much?
The NHS says 0.9mg (900 micrograms) or less a day from supplements is unlikely to cause harm.
Can biotin affect blood tests?
Yes. High-dose biotin can interfere with some laboratory tests, including thyroid and heart tests. Tell your doctor if you take it before any blood test.
