Yes, SkinnyFit is a legitimate company. It is a wellness company offering supplements that aim to support whole-body health, energy levels, and physical activity. However, it's worth noting that while the website boasts thousands of five-star user reviews, few of its products have robust scientific backing to validate claims. Also, it received a “B” rating from the BBB. They also have an average of 1.13 out of 5 stars based on 31 customer reviews. In all, 67 customer complaints have been closed in the last three years and 60 in the past 12 months. SkinnyFit has been accredited by the BBB since 5/23/2022. So, while it is a legitimate company, customer satisfaction varies.
