About This Product


This is the most important ingredient in any homemade fruit fly media. Josh's Frogs Brewer's Yeast is the highest quality around. Full of vitamins and high in protein.

Brewer's Yeast (dried Saccharomyces cerevisiae) is a great source of B-vitamins, protein, omega fatty acids, antioxidants, and trace minerals. The proteins present in brewer's yeast are highly digestible, and a great source of vital amino acids. This yeast is also a great source of energy. 

Brewer's yeast is a by-product of beer brewing. Supplements containing brewer's yeast often contain non-living yeast, or "postbiotics".

Josh's Frogs Brewer's Yeast is an important additive to fruit fly media. Brewer's yeast's high nutritional content and extra protein result in healthy, booming, nutritious fruit fly cultures. Josh's Frogs strongly recommends the addition of brewer's yeast to any fruit fly media. Josh's Frogs is the largest producer of 32 oz Fruit Fly Cultures in the world, shipping out over 30,000 cultures last year. We know what we're talking about!

Brewer's yeast also has it's uses in other animal feeds. Brewer's yeast is great for the skin and coats of dogs and cats. Regular addition of Brewer's yeast to the diet of a dog or cat also can drastically reduce shedding. Brewer's yeast also enhances the immune system, and helps the animal deal with stress by providing B vitamins.

Brewer's Yeast should be fed daily in small quantities. It can take up to a month for the effect of brewer's yeast to become apparent.

Brewer's yeast can also be an effective flea preventative by mixing ¼ cup of Brewer's Yeast with 1 quart of water, and spraying the animal's coat daily. This will not kill eggs, but will repel any adult fleas. It will also result in a shiny, smooth coat. This can also be used to treat dry skin.

Great quality

I’ve used some cheaper non froggy type brands before that just didn’t help as much as the booms I see in my countries with Josh’s brand

I love this stuff. Shipping from Josh's was not ideal as the package was damaged while in transit, but overall great product and price.

The absolutely best supplements for humans yes I said humans

I've tested this out at 55 years old and I can't remember when I felt this good in a long time. It increases your overall wellbeing without any side effects. You only get better and better in every department. Men get stronger and better. And Women do the same but they lose extra fat and become Increasingly less hungry you start eating less because of the vitamins and nutrients ect. My son went bananas his muscle mass increased but lean shredded muscle. I know it's marketed to dog's and cats ect but my quails, chickens, dog's wife children have all benefited from taking Brewers Yeast everyday except the quails they got to big and was way to active. Especially the males I don't have enough females. I digress!! But seriously I stop buying from Big AMA 25 buck's aaaaaa no thank you. But I strongly recommend this as a multivitamin you will never regret that decision. I love Josh Frog's Brewers Yeast it's for everyone in my opinion a d you feel soooooooo good for using it . Highly, highly, highly recommend
