Solgar Biotin 1000ug
- Product Review (submitted on 7 October 2021):
- Solgar's supplements are always very good quality, they are a bit pricey, but also not ridiculously so. I wanted to try these because my nails have never been very strong, but I haven't really used them for long enough to start seeing a difference. Either way, I usually stick with Solgar for supplementation because of the quality.
