What it does

An enteric-coated, specialised globular protein that supports mucosal resilience and immune function.

A naturally occurring protein found in milk that's part of your body's innate immune defence. It interacts with your gut microbiota, epithelium (gut lining), and immune tissue.

The enteric coating protects the protein from stomach acid, delivering it intact to your small intestine.

How to use

Take as directed on the bottle.

Continue alongside Prebiotic, yogurt, and pH Sachets.

Most people tolerate Immuno Protein well from day one.

Ingredients

A specialised globular protein extracted from premium bovine milk by ion-exchange chromatography. Refined and enteric-coated (shellac-based) in Japan for intact delivery to the small intestine.

Other ingredients: lactose, cellulose, CMC-Ca (binder), sucrose fatty acid esters, L-arginine, D-sorbitol.

Allergen: contains milk. Halal and kosher certified at the raw-material level. Non-GMO.

What to expect

Week 1: Begin immune support. The enteric coating ensures delivery to your small intestine.

Week 2-4: Continued use supports mucosal resilience and immune function alongside the Nourish phase protocol.

Ongoing: Maintain as part of daily MEND protocol for sustained gut immune support.

— Why Progurt

Not all probiotics are the same.

Most probiotics use strains from soil or dairy. Progurt uses strains identical to those colonising a healthy human gut from birth — at a clinical-grade dose, delivered intact to where they need to land.

    I take it every night

    I have been taking the Immuno Protein every night as well as the Enzymes for about 2 months. I immediately noticed my sleep improve as well as energy during the day. I have two sick children this month and have not gotten sick. I'm about to start giving it to the whole family. Absolute recommend from me.

    WOW,WOW,WOW

    What an amazing product. Right from the first night I slept so much better. I suffer with IBS so I noticed ever since my tummy has been so very much better. Also,I noticed that day on waking I felt happy and calm, great for anxiety. Im so glad I received the free sample as I would not had bothered to give it a go.

    I now take the Progurt every day that I make in the machine as well as my Immuno Protein.

    Thank you so much for bringing such another amazing product to the market place. Keep up your amazing work.
