What is microbial biotic protein?

Microbial protein is obtained through an innovative process from Methylococcus capsulatus (Bath as yes first discovered in the hot springs in Bath!) It is a natural, methanotrophic microorganism that uses methane as an energy source  - you cannot get more sustainable than that as it feeds off fossil fuel! This protein is produced through a special fermentation process and provides particularly high-quality and easily digestible proteins and dogs love its umami taste.

A study by Oba et al. (2023) confirms that microbial biotic protein has high digestibility and contains ALL essential amino acids, making it a complete protein source for your dog. By using microbial protein and the delicious grain-free natural ingredients in MicroBell, this food is hypoallergenic and therefore particularly suitable for dogs with sensitive digestive systems or allergies. 

The other best bit is that this microbial biotic protein has a mild umami flavour that dogs just LOVE so you can feed your dog a cruelty free food that is not only good for them, but good for our planet too!

Products chosen for My Own Dog

As a UK based passionate plant powered vet with over 30+ years of experience, I saw too many pets suffering from preventable allergies and painful digestive issues. I created Just Be Kind to provide a one-stop-shop of delicious products that I'm proud to recommend for all of your dogs as it's what I want for my own dog Ruff.

All of the products available are soya-free, gluten-free, nutritionally complete, cruelty-free and with a delicious taste that dogs (and cats) crave!

I am blown away almost everyday by the stories that you share with me about your dogs and cats and feel so grateful that I can help in such a natural and positive way.
