This week, I read what I consider to be one of the most comprehensive, practical guides to repairing and maintaining your immune system: a relatively short, easy-to-read online manual entitled: “Biohacker's Handbook to Invincible Immunity“. 

This book, written by the same biohacking and physician group from Finland who I highlighted in my article “21 Unfamiliar Nutrition Tricks I Discovered In The Biohackers’ Handbook“, delves deep into:

-Your immune system and how it functions…
-Viruses, bacteria and other pathogens…
-Innate immunity you are born with…
-Adaptive immunity that can be trained against pathogens…
-Individual differences and environmental factors…
-Measuring the condition of the immune system…
-Recipes for lowering inflammation and balancing the immune system…

After reading it, I reached out to one of the co-authors, my friend, beast of a powerlifter, complete biohacking nerd, and Finnish physician Olli Sovijärvi, to give me a synopsis of his top thirteen immune-boosting strategies found within the book. And you're going to discover exactly what he had to say below.

If you really dig this stuff and want to dive in headfirst, then follow the links I have at the end of this article to grab the book for yourself…

…and if you really want to take a deep, deep dive, then I invite you to join me, along with Dr. Rhonda Patrick, Europe's top biohacker Teemu Arina and many more – to the November 18 Biohackers’ Summit in Helsinki, Finland (use 10% discount code BEN), which is also organized by Teemu and his team, and is the best marriage of ancestral living, wild plant foraging, smoke saunas, amazing food and biohacking you’re ever going to experience. 

Alright, let's do this…


13 Underground Immune Boosting Strategies You've Probably Never Heard Of.

Yes, it is actually possible not to have a seasonal flu every year or catch a cold whenever you confront a stressful life situation. For example I have not caught a cold in five years. Before that it was normal for me to go through anginas, bronchitis and colds at least once a year.

Little did I know back then what the antibiotics I was using for these issues did to my defense system. Now I know that a single unnecessary course of antibiotics can actually destroy as much as 30% of your good bacteria. And as Hippocrates put it some 2000 years ago: ”All disease begins in the gut.”

But immunity goes beyond simply avoiding antibiotics, and if you want to build yourself an invincible immune system, I'd highly recommend you read on.

The word “immunity” originates from the Latin word immunis, which means “exempt”. Generally speaking immunity consists of all of the body’s defense systems that resist infections and toxins. The immune system can be thought of as a military defense system resisting uninvited guests.

To put it dramatically, the troops patrolling the body mercilessly attack intruders, blasting bacteria, poisoning parasites, devouring viruses and forcing cancer cells to commit suicide. Although functioning as a cohesive system, immunity is made up of various parts. A rough distinction can be made between innate (nonspecific) and adaptive (specific) immunity.

You can read a comprehensive yet straightforward description of the immune system in the Biohacker's Handbook to Invincible Immunity chapter that delves deep into making your immune system unbeatable, but below I have picked up some strategies for you that you may have never heard of.


1. Be Social.

Be social even if it wouldn’t seem to be your cup of tea. Lack of social contacts may be deleterious to your immune system and vice versa. For example, researchers at the University of Virginia School of Medicine have discovered that the immune system directly affects mice’s social behaviour, such as their desire to interact with others. Blocking a single type of immune molecule made mouse brains go hyperactive and caused abnormal behavior – but restoring it fixed both.


2. Laugh

Laugh often and avoid taking things too seriously. Frequent laughing has been found to lower stress hormone levels and boost the production of white blood cells and lymphocytes, which means better functioning immune system.


3. Drink The “Immune System Reset”

Bellow is my immune system reset recipe, clipped straight from the book, especially useful for “bouncing back” if you have been sick or protecting yourself if you've been exposed to the sniffles:



4. Lose The Gut

Reduce belly fat and get lean. Obesity, particularly in the form of abdominal fat, has been shown to increase leptin and decrease adiponectin levels, which seems to negatively affect the activation of immune system cells. The “Look Good Naked” article from Ben here is a perfect place to start.


5. Hydrate Your Saliva

Drink enough water daily. This may seem obvious, but do you actually know how dehydration impairs the function of your immune system? It decreases saliva antimicrobial proteins that are important for mucosal immunity.


6. Quit Stuffing Your Face.

Practice fasting every now and then. Fasting is an immemorial practice that throughout time has been suggested as a miracle cure for various ailments. In studies conducted on mice, regular fasting of 2–4 days per week for a period of 6 months decreased the function of the PKA enzyme (protein kinase A), making it possible for the immune system to rebuild damaged cells.

7. Drink Flu Killer Soup

This soup is great for you anytime but if you get exposed to the flu or get the flu, this recipe below, clipped from the book, is chock full of ingredients that will banish the flu fast.



8. Have Sex, But Not Too Much.

Sex can boost your immune system. Researchers have found out that regular sex is associated with higher IgA levels in the saliva. The same researchers also noted that having sex three or more times per week did not add any benefit to once a week group, but actually diminished the positive effects on immune system.


9. Take 5g Creatine Per Day

You can use creatine monohydrate not only for cognitive performance, power and strength gains but also to lower the inflammation in your body. Studies have shown that using creatine can inhibit the increase of CRP and TNF-alpha.


10. Add In The “Holy Trilogy”

What do astragalus, echinacea and cacao extract have in common? I call these three my “holy trilogy” of immune system maintenance, and all can lower CRP and have an anti-TNF effect, which means lower inflammation in the body. This is especially great news for people with rheumatoid arthritis or other inflammatory and immune related conditions.


11. Eat ‘Shrooms

Use various medicinal mushrooms (for example Chaga, Shiitake, Maitake and Turkey tail to name a few) to create yourself an intruder shield.Fungi have been found to contain several substances that are likely to become more and more relevant in the treatment of illnesses and the development of new medicines. Many known fungi compounds kill bacteria and viruses. They also possess immunoregulatory properties. Practically all medicinal fungi are rich in complex sugar compounds such as beta-glucans which activate NK, T and B cells and macrophages. They also increase the levels of cytokines (interleukin 1 and 2), thus boosting the function of the immune system. Ben's top source is Four Sigmatic Foods, based straight out of Finland.


12. Drink Extra Virgin Olive Oil

Use extra virgin olive oil liberally (the better the quality the more profound your results, as you can hear about here). It has been shown that good quality olive oil can reduce CRP and IL6, which lowers inflammation. But then again, bad quality olive oil can actually make things worse, since these are often rancid, not ”extra virgin” and sometimes cut with inflammation induction high PUFA-oils.


13. Try The Alchemist Power Drink

Here's another of my favorite (and probably most powerful) immune-boosting drinks, straight from the book:


And yep, it actually doesn't taste too bad. You can learn far more about various other immune system modulative plants, mushrooms and herbs and discover more recipes in the book. Bon appetit.

    Brilliant info here and we have such great opportunity to be proactive with our self-care, especially in the World we live in today.

    I love these 13 strategies shared by Ben and inspired by “Biohacker’s Handbook to Invincible Immunity“.

    Only one missing here, that is not perhaps underground, is movement. But over looked by many.
    I say health, strong body, healthy mind and immune system swat teams.
    Daily movement can be anything from a group fitness session, which can be great for connection and socializing too. Level it up y taking it outdoors. Take a walk, hike, perhaps going for a short run or bike ride, great for the mind.
    Maybe you get outside on your deck and do a quick HIIT workout or lift some weights or resistance training.
    Movement and exposure to the Sun is so essential especially in these winter months.

    Have fun with it and let’s level up the awareness and opportunity we have in 2021 to take our health back and have a kick arse immune system. Make it a great year and happy New Year.
    Cheers Ben
    In Vitality,

    Coach Kern

    I have had a bad rash and blisters on my hands for years, gone to many Dr’s and dermatologist. Finally I was speaking to my daughter and she told me it might be parasites, started juicing and taking lots of vitamins and drinking Apple Cider Vinegar, and in two days start seeing a difference, sometimes you have to step out the box. Thank You Lord for my common sense.

    Ben promoting and selling dangerous toxic treatment without good research to back it up? Not surprised. I know s couple of girlfriends who became ill after taking his immunity boosting mushrooms. Immunity boosting? That’s not even a thing. You know how to tell? There is no way to measure that.

    Hi Ben,

    Big fan of yours and love your content, BUT really felt the need to highlight the danger of following your “Immune Drink” (#3). ALA is a heavy metal chelator (as well as being beneficial to liver health etc) and in particular it helps chelate mercury out of the body. This sounds great, but extreme caution needs to be exercised when taking ALA since it has a half life of ~3-4 hours. If it is taken off its half life then the chelated mercury gets dropped and there is no ALA in the system to pick it up and carry it on it. This sort of distribution can be, and indeed has been, catastrophic to anyone with mercury toxicity. Unfortunately most of us are mercury toxic to some degree (amalgams, vaccines, environmental exposures, broken CFL light bulbs etc) hence ALA should generally never to taken off the half life, as you have suggested. For reference, google Andrew Cutler, who has cured thousands of mercury toxic adults and vaccine damaged (typically autistic) children using ALA dosed at appropriate amounts and times. See here:…

    I take Olive Leaf Extract every night at bedtime. I no longer get colds or sinus infections which were a spring and fall ordeal for years.

  6. Dr. Welby says:

    All looks good, except possibly the L-Glutamine, which is an excitotoxin.

  7. Heidi says:

    Thanks for sharing that with us Ben. I appreciate how generous you are with your time and incredible knowledge. You inspire me so much.

    1. not in everyone! depends on gut integrity.
