Biotin: Please start taking it once a week and gradually take it every other day. If you are tolerating this you don't need it more often. If not, feel free to take it daily. I strongly suspect you won't need it every day.

10,000 is big number: A normal person (without biotin deficiency) eating a well-balanced diet can be just fine without buying additional biotin supplements. The NIH reports: no recommended dietary allowance (RDA) for biotin; but adequate intakes for biotin are 7mcg for infants, 8mcg for children aged 1-3 yrs, 12mcg for 4-8 yrs, 20mcg for 9-13 yrs, 25mcg for 14-18 yrs, 30mcg over 18 yrs, 35mcg for breastfeeding women.

A 32-year-old member asked:

How much water should I be drinking every day if I am ok?

8c of any liquids: The typical recommended amount of fluid to take in daily is around 8 cups. That includes water, milk, juice, other beverages & liquid from foods like fruit. Thirst indicates too little. The ideal varies from day to day depending on heat, activity, etc. However, most women should try to drink a cup at and between each meal/snack and at bedtime to keep the fluid level steady, especially if pregnant.
A 27-year-old member asked:

I wear a pad everyday. Do I need surgery, or is there something else available?

Depends: I assume you are meaning a pad for vaginal bleeding. No matter your age, you should not be bleeding on a daily basis and this requires medical attention. If you are older, this could be a sign of cancer and needs to have a biopsy to fully evaluate this condition.

I have trouble remembering to take my oral medication every day. What's a good way to remember? What should I do if I forget a dose?

Pair it: Pair the medication with an activity you already do every day, like brushing your teeth. Put the bottle by your toothbrush. If you miss a dose, do not double up the next day. Just continue to take it as prescribed and if you miss a dose, you miss it.

How much iron do I need every day?

Dr. Scott Mitchell

It depends: This question is very complex and depends on a lot of factors. If you are healthy and not anemic, and eat a well balanced diet, you will likely get the iron you need from your diet and not require any supplemental iron. For an excellent reference that breaks down iron requirements see the nih's web page on iron information and daily intake requirements at http://ods.Od.Nih.Gov/factsheets/iron/#h.

No, rest is crucial: Periodsnof rest can be as important as the workouts themselves if you want to improve overall fitness (strength, endurance, speed).
