Take your immune health to the next level!

You perform your best when you feel your best. Give your body what it needs to keep up with modern day demands. Immune Defense is specially formulated with three specific goals in mind to help keep us healthy and functioning at the highest level possible!*

    • GOAL 1: Act As The First Line Of DefenseImmune Defense is designed to boost our natural defenses and to support our immune system function.*
    • GOAL2: Support Recovery - Immune Defense is designed to help support recovery so that you can get back to the important things in life as fast as possible!*
    • GOAL 3: Bolster Overall Health - Immune Defense is designed to support many aspects of general health including optimizing pain management, promoting cognitive function, and supporting healthy inflammatory and oxidative responses.*


Immune health is all about balance. 

Most immune boosting supplements lack balance and Natrium Health wanted to change that! An under-performing immune system makes us susceptible but an overactive immune system exposes us to equally undesirable effects. With our Immune Defense formula, we aimed for unrivaled balance! Our formula defends your health by fortifying immune system function while keeping the immune system from working against itself.*

Immune Defense is fortified with the following eight, all natural ingredients to support maximum immune function.*


These five active ingredients in Immune Defense help protect us on a daily basis.*

Functional Yeast Extract

      • FUNCTIONAL YEAST EXTRACT: A great prebiotic derived from yeast that is high in beta-glucan content to help support our natural immune defenses.*

The beta-glucan content of yeast is very high, and through extraction methods, we have been able to standardize to an impressive 50% beta-glucan content! Beta-glucans, by acting as prebiotics, help facilitate the growth of probiotics in our gut. It has been shown that a healthy balance of probiotics in our gut can help us stay healthy. The makes our functional yeast extract a very capable immune defender!*

Black Seed Oil Extract

      • BLACK SEED EXTRACT: A highly potent extract of Black Seed Extract that contains 5% Thymoquinone. Black Seed Extract has been known for thousands of years to help fortify immune function.*

Black seed extract has been used for centuries. Through detailed analysis of research studies, we have found that thymoquinone content is a major reason why black seed extract enhances overall health and immune function. With this in mind, we set out to find the strongest possible black seed oil and turned it into an easy-to-use powder. The high thymoquinone content in Immune Defense helps to balance our immune response. Thymoquinone helps regulate inflammatory and oxidative processes that can go haywire during a strong immune response. By regulating these processes, thymoquinone helps us stay healthy.* 


      • OLEAMIDE: Helps balance our natural immune defenses by increasing endocannabinoid activity. Oleamide helps protect us from immune system over activation while also supporting a healthy immune response.*

Oleamide is a fascinating compound that is naturally present in our bodies. It mainly helps regulate sleep. However, in lower dosages it is great at balancing our immune response. Oleamide works through our endocannabinoid system which has been shown to play an important role in immune function. A large majority of immune cells contain cannabinoid receptors which makes the endocannabinoid system and important target for us. It has recently been found that one of the most popular plant extracts, Echinacea, contains small amounts of compounds that act on the endocannabinoid system to help produce a balanced but strong immune response. Oleamide is a more direct and potent way to produce this endocannabinoid regulating effect. This makes Oleamide a very novel and effective immune defender!*


      • TYROSOL: A highly potent health-promoting compound found in Rhodiola rosea and olive oil, in its pure form!*

Tyrosol is one of the main compounds in Rhodiola rosea and olive oil and has been shown to produce potent health boosting effects. Rather than using Rhodiola rosea extract or an olive extract, we decided to go straight to the source and use pure Tyrosol to produce the most direct health boosting effects. Together with the beta-glucan from the Yeast Extract, this helps boost primary defenses.*

Red Reishi Extract

      • RED REISHI 16:1 MUSHROOM EXTRACT: A highly potent extract of one of the most effective immune balancing mushrooms! Used for centuries traditionally to help regulate our immune system and to keep us healthy.*

The triterpene content of  Red Reishi helps to significantly strengthen our immune response. It does this by increasing the amount of various immune factors which are naturally present in our bodies. Since the triterpene content appears to be the most potent immune booster, we decided to use a highly concentrated 16:1 extract which has a higher ratio of triterpene compounds. The immune boosting effects of Red Reishi are very balanced but packs a potent punch and is one of the best immune boosters around! Afterall, it has been used traditionally for centuries for the purpose of immune defense, and modern research is now backing up centuries worth of Red Reishi supplementation.*


These three active ingredients in Immune Defense help support recovery when we don't feel well!*

Turkey Tail Mushroom Extract

      • TURKEY TAIL 8:1 MUSHROOM EXTRACT: Turkey Tail is a highly potent immune regulating mushroom.*

Turkey Tail is a fascinating mushroom that contains a plethora of potent immune regulating compounds. It has been shown that Turkey Tail Mushroom helps to boost immune factors that help restore us back to health. This is why we have decided to include this mushroom alongside Red Reishi. Immune Defense offers the most potent duo of mushroom-based immune boosting effects!*

Sucrosomial Zinc

      • SUCROSOMIAL® ZINC: Enhanced levels of zinc when not feeling well helps support our bodies immune response.*

Zinc is something a lot of us have been told to take when we don't feel well. However, it is often a very low bioavailable form of zinc that is supplemented. We sought to change this, and included an intelligent dose of a very high bioavailable zinc supplement called Sucrosomial zinc. Sucrosomial zinc, is zinc oxide, which has been microencapsulated in a sucrose ester. The sucrose ester has a very easy time absorbing into cells, which allows us to deliver zinc exactly where it needs to be. This is important as it has been shown that zinc helps immune cells to exert their immune defending actions.*


      • PALMITOYLETHANOLAMIDE: Palmitoylethanolamide is widely known as a pain management supplement, however, one of its original uses was to support healthy immune function.*

Palmitoylethanolamide is a fascinating compound which is naturally present in our bodies, and like Oleamide, plays a role in endocannabinoid signalling. Palmitoylethanolamide has been shown to support the immune system when we don't feel well. The addition of Palmitoylethanolamide  helps allow you to get back to what’s most important as quickly as possible!*


Every ingredient found in a Natrium Health supplement must adhere to the following three criteria:

  • It must be tested.
  • It must be effective.
  • It must be powered by nature.

    Helped me a lot

    I am a teacher and during this cold/flu season, I was taking one capsule in the morning and one capsule when I came back home from work. I was surrounded by kids/staff who had colds, flu, Covid etc and thankfully I managed to avoid getting sick and I honestly believe it was due to Immune Defense. I will be getting more of this for sure!

    So far so good

    I think I’m on my 3rd bottle and so far I’ve managed to avoid the colds that are always going around my house for whatever that’s worth. I ordered this product because it combines micro zinc and beta glucans which I would otherwise supplement with separately so this is convenient and apparently effective for me. YMMV.

    Great for taking over the winter

    I got some immune defense to keep my body healthy through the winter. The mushroom extracts it contains are very appealing to me and ND/NH seems to have found a nice blend to keep pathogens at bay.

    Great For More Than Just Immune Support

    During the times we are experiencing now, I decided to get this and also take their MicroZinc along side each other. I’m also taking a few other immune support products they offer. Along living a healthy life style, I feel like I’m doing all that I can to help prevent immune deficiencies. Supplements like this allows me to feel like I’m in good hands and I’m doing all that I can and beyond for my body and mental health. Alongside the immune support properties, it has also helped my mood. I’m thinking it’s probably due to the Nigella Sativa but it could be the whole concoction air supplements. Either way, I wasn’t expecting to have it increase my mood so well. I take it in the morning. I’ve recommended this product to many of my family members whom I care for to help keep them in good hands as far as immune support goes.

    Real Life Alchemy

    I usually take weeks to months to write a review because it's hard to isolate the effects to a point you are comfortable sharing. However, this product is too powerful and it was easy for me to estimate the magnitude of its effects since I was, coincidentally, sick, when it arrived. I'm a very healthy person (M, 27 y-o) and bought this product for my father. I took some doses because I was sick, with low fever for almost one week and some chest pain and a random inflammation on the intestine. The high inflammation levels became clear once my face started to accumulate some red spots, and a very small inflammation I had on the heart started to be more noticeable. This heart inflammation was a sequel of a weird sickness I got and probably all the symptoms were the consequence of my immune support deregulated through the weeks, after this. And this product basically solved everything in two days, with the first dose accounting for 70% of the effect. Honestly, I need more than 3 days of sleep deprivation to start to feel bad. I always liked to test my limits and my health stack (nac, milk thistle, etc) was more than enough . Always. But this product is on another level. it's hard to put into words. Real life alchemy idk

    Changed my Life!!

    Every year at this time, my two grandchildren come down with the flu and it leads to bronchitis. I get sick right along with them. Sure enough, they got sick before Christmas and it is still dragging on. Since I have been using Immune Defense, I have not been sick and I have only had a small cough this time around. Thank you so much for bringing such a quality product out. The difference it has made for me is great!!

    Works like magic

    This stuff is pretty much straight up magic. Started to get sick, took it, and was feeling better within hours. Same story for my girlfriend, and a handful of friends we have this too. As someone that's taken Epicor for years, this blows it out of the water.
