CarlsonBiotin, 5000 mcg, Healthy Hair, Strong Nails & Energy Production, 100 Capsules

It works, I do want to share for those of you with hypothyroidism, this may interfere when doing labs to check on thyroid levels, does not interfere biologically, interferes with the way the lab reads levels, hard to describe, have to either stop taking prior to labs or ask doctor if taking this will interfere in blood results with the lab your using.Anyhow, it works, I see a difference in my hair and nails, my nails are stronger than they have been in a long time, I do not see me losing as much hair when combing through it, I see also some baby hairs coning in and my hair is growing faster.

As you get older your body does not work as well when were younger. Biotin helps with hair and nails to work better. I have been taken for over 15 years and I will keep taken it until forever. A great supplement to stay healthy as you age. It is great at any age,

I like the way they use the brown bottles, to protect from sunlight. Is that something you want for vitamin d ,I do not know. But the doctors say takle biotin, especially, when your eyebrows won't grow. Biotin is for helping this, when you have vitamin deficiency.....

It was good, no problem.
