GNC Biotin Review - Does It Work?-Review

What Is GNC Biotin?

Biotin is a form of vitamin B, present in many foods and available as a supplement. Biotin is sold under many names, such as appearex, vitamin B7 and vitamin H. Many multivitamins and B-vitamin supplements also contain biotin. Biotin works by breaking down food into sugar that your body can use for energy. This product is important for healthy skin and nails, and it also keeps nervous system working properly.

Ingredients And How it Works

Main Ingredient

  • Biotin (5000 mcg)

Biotin is widely available as a supplement in a number of different compositions. The adequate intake for adults is 30 micrograms per day. Therefore, a 5,000 microgram biotin supplement is very high potency. Scientists have yet to determine the safety of such high-potency individual vitamins.

Other Ingredients:

Dicalcium Phosphate

Cellulose is a  largely indigestible polysaccharide (a complex carbohydrate), composed of thousands of glucose molecules. Cellulose is not an essential nutrient, which means you do not need to consume it in order to be healthy.
Gelatin is a translucent, colorless,and  flavorless food which is usually derived from collagen that is sourced from various animal body parts. It is commonly used as a gelling agent in food, pharmaceutical drugs, vitamin capsules, photography, and cosmetic manufacturing.
Dibasic calcium phosphate is used as a dietary supplement in some breakfast cereals, enriched flours, dog treats, and noodle products. It is also used as a tableting agent in some pharmaceutical preparations.

Daily Serving

It is suggested that one capsule is taken daily. After thorough research no further information was given as per the product label, however, we would suggest that the supplement should be taken with meals.

The Cost

To purchase this product the price per bottle of 240 capsules is  $37.99. This product can be bought online and directly at retail stores. The manufacturer does offer promotions and free shipping on orders over $49.

If the item was bought online the manufacturer gives instructions to follow as to how to return the item.

Our Review Summary Of GNC Biotin

In our review of GNC Biotin, we have found that there are a few customers which are satisfied with the product. We also find this product is affordable. However, the guarantee does not include a 365 100% money back guarantee, which most leading brands offer. A serious matter of concern is why the GNC does not warn potential customers about the allergy risk as gluten is utilized as an ingredient in their formulation. We also would rather prefer an eco-friendly non-gelatin capsule. To sum everything up, we, unfortunately, cannot recommend this product.
