Neither vitamin B nor vitamin B1 can repel mosquitoes, and there is no reliable scientific basis to prove that eating vitamin B1 can prevent mosquito bites.
1. "Life Times" reported that people believe that vitamin B1 can repel mosquitoes first came out in Western countries in the 40s of the last century, because vitamin B1 smells faint and tastes bitter, so people take it for granted that after spraying the drug on the body surface or taking oral drugs, the blood will also produce the same taste, which can make mosquitoes discouraged.
2. "Life Times" explained that current research has confirmed that B vitamins do not repel mosquitoes. Mosquitoes do not have the same preference for smell as humans, and vitamin B1, which makes people feel disgusting, does not have an effect on mosquitoes.
Hualong also reported that these claims are not only theoretically unauthoritative, but also not confirmed in experiments. The smell of vitamin B1 does not repel mosquitoes, and due to its unstable nature in water, spraying an aqueous solution of vitamin B1 is unreliable.
3. In the mosquito repellent formula of vitamin B1 circulating on the Internet, the oral formula dose is close to 100 times the normal human body requirement. Although there are few reports of harm from excessive vitamin B1 consumption, excessive vitamin B1 consumption may interfere with the absorption of other B vitamins and the secretion of insulin and thyroxine.
4. Whether spraying a solution made of vitamin B1 on the surface of the ** will have adverse effects on the body. Just spraying vitamin B1 on the surface will not produce ***. Although vitamin B1 is easily soluble in water, from its molecular structure, it is very unstable, sensitive to heat, and easy to decompose when exposed to light.
Therefore, even if vitamin B1 dissolved in water does have a mosquito repellent effect, spraying it on the body will completely decompose in a short time.

Mosquitoes are afraid of vitamin B1. This vitamin enters the human body and is metabolized and excreted from the sweat glands, giving off a special smell that mosquitoes flee in fear of. Vitamin B1 can be dissolved in water, and the exposed limbs can be wiped with a tampon ball dipped in the solution, or directly added to the bath for bathing.
