GNC Biotin Review

Manufacturer’s Claim

Today, we are going to review Biotin 5000 mcg. We have composed this review to assist consumers in making the right decision about purchasing the product. Our review states the facts about the product to educate consumers. GNC formulated the product to help you support healthy hair, nails and skin.


The active ingredient in the product is Biotin, which consists of 5000 mcg. The ingredient helps to promote healthy hair, nails and skin. The ingredient also helps to promote a healthy cardiovascular system and supports a healthy metabolism. The inactive ingredients in the product are Dicalcium Phosphate and Cellulose.


If you are considering consuming the product, make sure that you speak to your health professional before consumption to get advice on the suitability of your condition. The manufacturer recommended that you consume 1 capsule daily. The manufacturer has not mentioned if food should be included with the dose or when the dose should be consumed to get the best results.


The manufacturer has packaged the standard bottle with a 100 capsules. You can purchase it from the official website for $37.99. The manufacturer has not offered a discount on the product. You will have to pay additional costs for shipping.

Possible Side Effects

The manufacturer has not stipulated any side effects of the product; however, we managed to track down consumers who did experience side effects. The customers stated that they had acne on their face after consuming the product.


We were disappointed to discover that the product does not come with a guarantee. That means consumers are risking their money when they purchase the product. If the manufacturer believed in the product’s ability to deliver consistent results, it would have included a guarantee. No guarantee means that the manufacturer does not believe in the product.

GNC Biotin Review – The Bottom Line

We have examined the product and have discovered certain factors that consumers will want to be informed. We have discerned that GNC formulated the product to help you support healthy hair, nails and skin. We also discovered several flaws in the product that consumers should be cognizant of. Consumers need to know detailed instructions of the dose to get the best product, which the manufacturer has not stated. We do not know if food should be incorporated into the doses or the time of day the doses should be consumed. The manufacturer made shipping costs an additional expense and has not offered a discount on the product. One of the biggest concerns regarding the product is that it does not contain a guarantee. Any product without a guarantee indicates that the manufacturer does not believe in its product. If the manufacturer believed that the product could deliver consistent results, a guarantee would be included. When we tracked down customer testimonials, we saw that consumers who purchased the product had negative feedback. Apart from stating that the product does not work, some consumers said that they experienced side effects such as acne on their face.
