Millions of Indians search for biotin every month but the biggest confusion remains the same:

“If the body needs only 30 mcg daily, why do supplements contain 1,000, 5,000, or even 10,000 mcg?”

If you’ve held a biotin bottle and wondered whether these high doses are safe or necessary, this guide clears everything in simple, practical language designed for Indian users.

Adults need around 30 mcg/day to prevent deficiency, but for hair growth most Indians take 1,000–5,000 mcg daily. Higher doses like 10,000 mcg are generally safe because biotin is water-soluble, but can interfere with blood test results.

1. RDA vs. Therapeutic Dose Why Both Matter

To understand biotin dosage in India, you must separate two completely different goals:

A) RDA / Adequate Intake (Minimum to Stay Healthy)

» Nutrition bodies list ~30 mcg/day as the amount needed to avoid deficiency.

» Most Indians easily meet this through food: eggs (anda), peanuts (moong phali), dals, whole grains, nuts.

» This low requirement supports basic metabolism.

This is the “survival dose.”
It does not guarantee thicker hair or stronger nails.

B) Therapeutic Dose (For Hair, Skin & Nail Results)

» This is where supplements enter the picture.

» Common therapeutic doses: 1,000 mcg → 10,000 mcg

» Most Indians report noticeable improvement with 5,000 mcg/day

» Higher doses aim to support keratin production, which forms hair and nails.

This is the “results dose.”
The body uses what it can; the extra gets flushed out.

2. Why Are Supplements So High (Like 10,000 mcg)?

Simple answer: biotin is water-soluble.

» Your body does not store it.

» Whatever you don’t need is excreted in urine.

» Toxicity is extremely rare.

Because of this safety profile, brands offer higher strengths so users can try a dose that supports visible benefits.

3. Is 10,000 mcg Safe for Indians?

For healthy adults, 10,000 mcg/day is generally safe.

However, one critical warning:

Biotin can interfere with blood tests

High biotin levels may give false readings in:

» Thyroid tests (TSH, T3, T4)

» Troponin tests (heart attack markers)

» Hormone tests (e.g., vitamin D, pregnancy tests)

Safety rule:

➡ Stop biotin 48–72 hours before any lab test.
➡ Always inform your doctor that you take biotin.

How to Take Biotin Correctly (Indians Often Miss This)

Take biotin with food

Improves absorption and reduces stomach discomfort.

Same time daily

Consistency matters more than the exact time.

Avoid raw egg whites

They contain avidin, which binds biotin and blocks absorption.

Stay consistent for 90 days

Hair growth is slow 3 months is the realistic timeline for changes.

Combine with these nutrients

Biotin works better when paired with:

» Zinc

» Vitamin D

» Omega-3

» Folic acid
