Certain smells naturally repel mosquitoes. Brewer’s yeast is one of them, being especially high in vitamin B1, thiamine, which is excreted through your pores when you sweat.
Can brewer’s yeast repel mosquitoes?
Yes. Consumption of brewer’s yeast can repel mosquitoes due to the odor excreted by your skin. It can’t be detected by humans but it is unpleasant for mosquitoes so if you consume foods rich in thiamine, mosquitoes will leave you alone.
By increasing your consumption of thiamine you naturally repel mosquitoes.

I know the primary topic of this article is whether brewer’s yeast can repel mosquitoes or not and it really can, but you have to consume it regularly at least in the time you are in an area full of mosquitoes. However, I also wanted to show you what a great (and inexpensive) source of vitamins, not only thiamine, and minerals it is. A natural one, without chemicals.
Other Sources of Thiamine
There are other food sources of thiamine which include beef, liver, pork, dried milk, eggs, nuts, oats, and other wholegrain foods, oranges, seeds, legumes, and peas. Foods are also fortified with thiamine. Some foods that are often fortified with B1 are rice, pasta, bread, cereals, and flour.
CONTENT OF THIAMINE IN FOODS
Brewer’s Yeast is not the only food that is high in thiamine, although the concentration is significantly bigger compared to other foods.

|Lean pork chops||0.7 mg|
|Flax Seeds||1.6 mg|

Recommended thiamine consumption
Men need around 1.0 milligram; women around 0.8 milligrams of thiamine per day.
My Personal Experience with Brewer’s Yeast
I found out about all the benefits of Brewer’s Yeast thanks to Adelle Davis’s books when I was studying at the university. Adelle Davis was a pioneer nutritionist and I learned a lot from her books. Since that time, I’ve been taking dried Brewer’s Yeast in form of tablets with my lunch every day and I believe it has helped me to prevent my hair from graying due to the high amount of zinc, magnesium, and selenium.
It wasn’t until recently that I realized I almost don’t get bitten by mosquitoes compared to my boyfriend when we are in a mosquito-flooded area. Of course, it doesn’t protect you a hundred percent but the amount of bites is significantly lower. The effectiveness of Brewer’s Yeast was researched and proven in this study.
How To Consume Brewer’s Yeast
There are various forms of Brewer’s Yeast: powder, flakes, liquid, or tablets.
Brewer’s yeast powder can be mixed with water or other beverages.
The average recommended dosage for adults is one to two tablespoons daily.
I prefer tablets because you can take them with you wherever you go and they are easy to consume – just like any other tablet, you have it with a glass of water or any other drink.
Recommended consumption is always described on the package.
What Is the Difference Between Brewer’s Yeast and Baker’s Yeast
Brewer’s yeast is an ingredient used for the production of beer, thus the name. It is not the same as the commonly used and known baker’s yeast. Both yeasts are made from strains of Saccharomyces cerevisiae, but each from different strains.
Brewer’s yeast and baker’s yeast are both made from strains of the Saccharomyces cerevisiae fungus, but each of them from different strains of this species. Brewer’s yeast contains chromium, which is an essential nutrient that may help regulate blood sugar, according to the Cleveland Clinic. As obvious from the tables above, it is also considered a good source of B vitamins, which are essential for our body.
Is Brewer’s Yeast the same as Nutritional Yeast
Nutritional yeast is a powdery or flaky yeast usually bought in bulk. Vegans and vegetarians enjoy it as a supplement, but others can benefit from adding it to their diets. It’s usually a form of Saccharomyces cerevisiae, which is harvested, pasteurized, and dried to deactivate it and enhance its nutritional properties. Brewer’s yeast looks similar has and is also derived from Saccharomyces cerevisiae, but it’s produced as the byproduct of beer-making. It, too, is pasteurized and deactivated. Nutritional yeast does not provide chromium, while brewer’s yeast does not provide vitamin B-12.
In the video below, Dr. Berg explains the difference between nutritional yeast and brewer’s yeast:
Are there any risks
Brewer’s yeast is a natural ingredient considered healthy and safe. However, if you are a diabetic or have any other serious health issues, you should consult your doctor.
There are several cases reported of decreased postprandial glucose in diabetics after taking brewer’s yeast.
Other Benefits of Consuming Brewer’s Yeast
Brewer’s Yeast can help with health issues such as diarrhea caused by antibiotics, traveler’s diarrhea, irritable bowel syndrome, lactose intolerance, and others. It may also maintain healthy skin, hair, eyes, and mouth and enhance the immune system.
Summary: Should You Consume Brewer’s Yeast To Repel Mosquitoes?
Brewer’s yeast is an inexpensive and excellent source of thiamine that is excreted with sweat; the odor is not pleasant for mosquitoes so you are safer than if you don’t have enough thiamine in your body.
You can increase the amount of thiamine that you consume in other foods such as salmon, trout, tuna, flax seeds, beef, green peas, and other sources mentioned above but thiamine content in Brewer’s Yeast is higher and you can be sure that if you take one or two tablets a day (I take two or three), you are taken care of.
Nevertheless, if you want to be safe from bites completely, it’s best to go for an external repellent as well. Unfortunately, the only one that protects you 100% no matter who you are and what you consume, is a chemical repellent based on deet.
Deet can irritate your skin and excessive exposure can be toxic. You can use a natural alternative to deet instead: Tea Tree Oil. Here is an article about natural insect bug sprays and my experience with tea tree oil: How To Keep Mosquitoes Away Naturally.
