Tag: Insect bite prevention

For decades, people have believed that taking a specific vitamin, particularly vitamin B1 (thiamine), can repel mosquitoes and other biting insects. However, controlled scientific studies have found no evidence that any oral supplement, including those with B vitamins, is effective as a systemic insect repellent.

While many anecdotal reports suggest Vitamin B1 (thiamine) can act as an insect repellent, recent scientific studies have repeatedly failed to prove its effectiveness against midges or mosquitoes. The question of what vitamin helps with midge bites is more complex, requiring a closer look at both popular folklore and evidence-based solutions.
