Good to have have for winter time!READ BELLOW!!I'm a fit girl and try not to overlook vitamin which may have a protective effect against Viruses, according to recent research of it's ingredients and at the same time has no taste.Also it's called vitamin of sun, but during the winter time when there is sun deficiency and there is no sun absorption through the body, you can take one big size package of this vitamins which are highest quality, and not only the immunity but also your bones will be healthy and strong. Regarding dosage, I take as written on package. THUMBS UP if you find this review helpful!!! I’m
Since I moved to a new country a year ago, I’ve been having hair loss from the shower water. I’ve been taking this biotin for 6 weeks (about half the time before you should start seeing hair loss results) in addition to using a shower head filter. Here’s what I’ve noticed so far:- my hair is generally healthier and growth is super fast- all body hair grows thicker and faster, especially brows and legs- some new baby hairs at the hairline!!- can’t tell if hair fall has reduced yet- scalp is less greasy and I can go an extra day without washing.My hair overall just.. feels nicer. I’m also very acne-prone but haven’t had issues with this.Will update in 6 weeks! I’m very hopeful.
My dry nails and hair seemed to show some improvement after I took biotin supplements. 21st Century is a reliable brand that produces high-quality products, and the price of biotin is not too expensive. Therefore, it was easy to purchase this biotin supplement. Since I took care of my nails and hair while taking this biotin supplement, it is difficult to say that this improvement came from the supplement alone. Still, I think it helped improve things more than not taking the biotin supplement.
If you don't have a deficiency and the 5000+ dosage is not prescribed by your doctor, take 800mcg or even less.I have been taking it for about two months. Hair has not stopped falling out, but new hair has begun to grow! I also take vitamin D and iron along with biotin, because I am deficient.But after a while, I got a strange rash on some parts of my body. Itching and spots on the side of my left breast and thighs.I suspected Biotin because I had seen reviews of different adverse reactions. After taking the drug off, a few days later everything went away.Definitely a quality product with quality ingredients! I wouldn't underestimate it. Just be careful and don't take large doses without indications.
