Recommended amount of Biotin for hair-loss/nail improvement?
Ive just bought a bottle of Biotin tablets to aid in my fight against hair loss and my brittle/discoloured nails (recently stopped biting my nails after approx 20 years of it).
I see now that it says on the bottle that its 300ug per tablet. Am I correct in saying that that means 0.3mg and only 0.0003g per tablet?!?
If this is the case, am I wasting my time taking these things thinking they're going to work. How much should I be taking to achieve any possible benefits?
