When You Want Extra Immune Support

Your gut–lung axis plays a key role in how your body responds to everyday respiratory challenges. When this delicate balance shifts, you may feel more vulnerable. AB21 combines clinically researched strains designed to help maintain this connection, giving you dependable support during colder months or periods of increased strain, so you feel steadier and more protected.

Trusted, Researched Support

The gut–lung axis is closely linked to the body’s natural defences, and keeping it balanced matters all year round. AB21 is a clinically researched formula offering targeted support for the gut-lung axis. Suitable for daily use or when your body needs some extra support. Gentle enough for children from age two and for adults, it provides effective, science-led care whenever you need it.

The gut-lung axis explained

It is not only our gut that is populated with good bacteria, but our lungs also have their own community of bacteria which interact with our immune functions and play a role in how infections progress.

Your questions answered

Probio7 AB21 is a targeted probiotic containing 4 clinically researched strains selected for their specific actions within the gut–lung axis. It also provides vitamin D, which contributes to the normal function of the immune system.

Each capsule provides 2 billion live bacteria from four clinically researched strains: Lactobacillus plantarum KABP™ 022, Lactobacillus plantarum KABP™ 023, Pediococcus acidilactici KABP™ 021 and Lactobacillus plantarum KABP™ 033. These strains have been studied for their role in gut and immune communication, including the gut–lung axis to offer a targeted, clinically led approach.

AB21 is suitable for adults and children aged 2+, making it ideal for families or anyone wanting targeted immune support linked to the gut–lung axis.

Take one capsule daily with breakfast.

Swallow whole, or open the capsule and mix the contents into cold food or a cold drink. Avoid hot food or drinks, as heat may affect the live cultures.

Yes. Take one capsule daily, spaced 2-4 hours apart from an antibiotic dose. Continue daily use after the antibiotic course for ongoing support.

No, AB21 contains no major allergens, no dairy, and no added sugar. It is shelf-stable and does not require refrigeration.

The gut–lung axis is the way the gut and lungs communicate through the immune system. The bacteria in your gut can influence how the immune cells in the lungs behave, and vice versa. AB21’s strains were chosen because research shows they play a role in this gut–lung communication network.
