High blood sugars negatively impact the immune system and can make it more difficult for your body to recover. Good control of blood sugars can help boost immunity and prevent certain infections by allowing the body’s normal defense mechanisms to function at their best.

How Does it Work


Works at a cellular level to help keep immune defenses strong. A healthy immune system can reduce the chances of getting sick and shorten the duration and severity of symptoms if you do get sick.


Zinc, Andrographis, and Quercetin work together in a powerful blend to support healthy sinuses and respiratory function.


Potent antioxidants help seek out free radicals that can damage immune cells.

Benefits of a Healthy Immune System:

  • Defense from getting sick
  • Reduced recovery time
  • Milder symptoms

This potent blend starts working quickly to support immune health! Generally after one week of daily use, the nutrient levels have built up high enough to offer benefits.




Also known as "Indian echinacea”, andrographis has immunostimulant properties.

Some evidence suggests that taking andrographis prophylactically reduces the risk of catching a cold by 50%. Also, it can help improve symptoms of the common cold after 2 days of treatment, but it typically takes 5-7 days for maximal symptom relief.

Mushroom Immunity Blend


Reishi &Turkey Tail Mushrooms, traditionally used in Chinese Medicine, support the natural production of white blood cells, which help fight infections.

The most important bioactive compounds in these mushrooms are Beta-D-glucans, which have the ability to support a healthy immune response.

What makes this different from other immunity products?

This is an important question – since there are thousands of other immune support products out there. The problem is that none of them are specific to diabetes health!

We don’t use the typical over-used ingredients like Vitamin C. The ingredients and doses are backed by medical research and are not only diabetic-friendly, but have added benefits of supporting healthy blood sugars, A1C levels, and insulin function. Healthy blood sugars are vital for a healthy immune response!

Do I need Diabetes to take this?

Absolutely not! However, people with type 1 or 2 diabetes will get the extra benefits of added blood sugar support.

How long does it take to start working?

Generally, 7 days of continuous daily use is enough time to build up the nutrients to a beneficial level.

Do I take this to avoid getting ill or once I am already ill?

The main goal of a healthy immune system is to avoid getting sick all together – in which case we recommend taking this supplement daily for year-round support. However, research shows the individual ingredients we use in this combination can
help shorten the duration of illness even when started within 2 days of symptom onset and continued for 5 days.
