Vitamin B-1 reduces bug bites effectively; adjusted dosage prevents noticeable odor while maintaining repellent benefits.
B-1 supplements reduced mosquito bites effectively, but high dosage caused odor; switching to lower dose recommended. Smooth delivery experience.
This review is from Amazon.com for product:
Source Naturals Vitamin B-1 Thiamin 500mg High Potency, 100% Pure - 100 Tablets
I bought this because I was getting eaten alive by mosquitoes and/or other bugs (yes, even in winter, the last mosquito alive would find me and bite several times) and read online that taking B-1 helps to deter them. And, it seems to have worked!
This is definitely high dosage though and I take it every other day now instead of taking it every day. Taking it every day made me feel like I could smell it exuding from my pores, which is what is supposed to cause the bugs to leave you alone, but it shouldn't be noticeable to humans. When I order B-1 again, I'll probably try to find a lower dose to take daily.
Was delivered as promised in good conditions. No complaints there.
Vitamin Basics & Tips
Vitamin B1 (thiamine) is often suggested as a natural mosquito repellent due to its ability to produce a skin odor undetectable to humans but unpleasant to insects. While the science behind this remains debated, some studies indicate that excess thiamine is excreted through sweat, potentially creating a protective barrier. However, dosage matters: typical daily recommendations for adults are 1.1–1.2 mg, far lower than many supplement formulations. Overconsumption may cause harmless but noticeable bodily odors, as described in the review.
Beyond insect repellency, B vitamins play crucial roles in energy metabolism and nerve function. Vitamin B1 specifically supports carbohydrate breakdown and neurological health. Deficiency, though rare in developed countries, can lead to fatigue or beriberi. For daily use, a balanced diet (whole grains, legumes, nuts) often provides sufficient B1. Those considering high-dose supplements should consult healthcare providers, as excessive intake might interact with medications or mask other deficiencies.
Other B vitamins like B6 and B12 also contribute to skin health and red blood cell production. While B1’s mosquito-deterring effect remains anecdotal for many, its role in overall wellness is well-established. Always prioritize moderation and professional guidance when using supplements beyond dietary needs.
