Biotin 5,000 or 10,000: which is better?

Question

I want to start taking biotin for my hair lost problem . but should I take 1 dose of biotin 10,000 in the morning . Or 2 dose of biotin 5,000 one in the morning and the other one in the afternoon ? Or it doesn’t make a difference ?

It should not make a difference as biotin does not help most people with hair loss. I’ve attached an interesting reference below that you can review. If you decide to use, be aware of side effects (acne etc) and be sure to review with your health care providers how it can affect your blood test results in the future. This is  perhaps the most import thing to know about when taking biotin. I’ve includes references to these too.

Biotin is a water-soluble vitamin that's a part of the vitamin B family and whatever dose you take, it will probably make no difference. The use of Biotin for hair loss has not been shown to have value
