Sure! Here's a detailed explanation of why 40 mcg is not enough to overcome biotin deficiency and why 10,000 mcg (like in Refollium's tablets) is often recommended:
🔍 What is Biotin?
Biotin, also known as Vitamin B7, is a water-soluble vitamin that helps your body:
-
Convert food into energy
-
Support healthy skin, hair, and nails
-
Maintain a healthy nervous system
❗ Why 40 mcg Is Not Enough
-
40 mcg (micrograms) is the Recommended Daily Allowance (RDA) for a healthy adult with no deficiency.
-
It’s the minimum amount to prevent a deficiency in someone who already has adequate biotin levels.
-
However, if you're facing:
-
Hair fall
-
Brittle nails
-
Skin dullness
-
Fatigue or low energy
-
Diagnosed deficiency (due to poor diet, stress, medications, etc.)
Then 40 mcg is far too low to replenish your body’s stores.
-
✅ Why 10,000 mcg Works Better
-
Therapeutic dose: 10,000 mcg is considered a high-strength dose used to:
-
Correct a deficiency faster
-
Stimulate hair regrowth
-
Improve skin texture and radiance
-
Strengthen brittle or weak nails
-
-
Clinically supported: Many dermatologists and nutritionists recommend 5,000–10,000 mcg daily for people experiencing hair thinning or skin problems.
-
It's safe for most people when taken under proper guidance, as excess biotin is water-soluble and is flushed out via urine.
⚖️ Comparison
| Dosage | Use Case | Effectiveness |
|---|---|---|
| 40 mcg | Basic maintenance, no deficiency | 🟥 Low |
| 10,000 mcg | Deficiency recovery, hair/skin care | ✅ High |
🛡️ Safety Note
-
Recommended Usage:
Take one tablet daily, preferably before breakfast or lunch, on an empty stomach for optimal absorption.Important:
Always consult your physician before starting high-dose biotin supplements, especially if you have any medical conditions or are taking other medications. -
Biotin may interfere with some lab tests, so inform your healthcare provider.
✅ Water-soluble & safe in high doses (excess is excreted in urine)
❗ Can interfere with lab tests (e.g. thyroid, cardiac markers) — always inform your doctor.
