For decades, people have sworn that taking a vitamin helps keep mosquitoes away, specifically citing B1 (thiamine) as a potent insect repellent. However, systematic scientific reviews have repeatedly found no evidence that consuming any vitamin, supplement, or food can deter mosquitoes.

The idea that taking vitamin B supplements can ward off mosquitoes traces back to a flawed study in the 1940s. This long-standing myth has persisted for decades, but modern scientific evidence has conclusively shown that there are no vitamins that are good for mosquito repellent and no ingested supplements will make you less attractive to these pests.
