What are Immune Support Supplements?

An immune support supplement can give you a lift when you're feeling low. It supports your immune system by introducing friendly bacteria that crowd out the bad bacteria.

BLIS immune supplements are designed for supporting mouth, throat, and gut health. We have a wide selection of supplements to choose from and use high-quality, high-CFU probiotics, as well as the finest complementary ingredients.

Your immune system is a complex and multifaceted biological structure that keeps diseases and infections at bay. It relies on an array of nutrients and bacteria to stay healthy and function at maximum capacity.

Probiotics play a massive role in this process. They are friendly, live bacteria that support your digestive health and immune system. The body doesn't produce it's own probiotics, but they are found in many fermented foods, including everything from kombucha (a type of fermented tea) to live yoghurt.

But eating more of these foods isn't always enough. Sweeteners are thought to affect the levels of friendly bacteria in the gut, and the modern diet is high in these sugar substitutes. Antibiotics can also harm your gut microbiome, and that's assuming you're actually eating enough fermented foods and getting enough probiotics in the first place!

BLIS immune support supplements contain billions of friendly bacteria, providing fast and easy immune system support.

When used as directed, an immune support supplement can have a massive effect on your overall health and well-being.

What Does an Immune System Support Supplement Contain?

All of our immune support supplements contain Streptococcus salivarius K12 (BLIS K12™), a strain of bacteria that supports the immune system.

It is naturally present in the body and resides within the oral cavity, but it's thought that just 2 to 5% of the population have concentrations high enough to be effective.

Some of our products also contain supporting ingredients that complement the probiotics for a more holistic approach.

For instance, Honey BLIS contains the highly sought-after Manuka and Kamahi honey, two of NZ's finest exports. These ingredients are praised for their antiseptic and antibacterial qualities and have a soothing effect on the throat. Honey BLIS lozenges don't contain any artificial colours or flavourings—just great honey and potent probiotics.

Immune Support FAQs

If you scroll to the bottom of our product pages, you should see a "Pregnancy Safe" label. This means that it's safe to take that particular supplement if you are pregnant. So, as long as you see that label, you're good to go!

It depends on the product strength and type, as well as the needs of the person taking it. Most of our immune support NZ supplements provide the best results when taken once or twice a day, but they can be taken up to 4 times a day.

There are various signs, including frequent infections, chronic tiredness, high stress, and lots of digestive issues. If you are experiencing any of these symptoms, you should consult with a medical professional to rule out other issues.

Probiotic supplements go a long way to supporting your immune health, but there are other things you can do. Eat well, drink lots of water, get plenty of sleep, and exercise. It also helps to add more fibre and fermented foods to your diet while avoiding cigarettes and alcohol.

As the body doesn't produce it's own probiotics, it relies on food and supplementation. You can eat fermented foods (kombucha, kimchi, sauerkraut, natural yoghurt, kefir) or take probiotic supplements.

If you're worried about the health of your little ones, we have a product specifically formulated for kids over 6 months old. Daily Defence Junior is a probiotic powder you can place on their tongue once or twice a day to support ear, nose, and throat health or sprinkle over cool food. Always consult the label before use.
