What Earns This Blend Its Place

Below is the fraction the immune work runs on, which mushrooms are in there, how the powder is made, the free-froms, the prebiotic fiber and who it was built for.

Beta Glucan, the Part That Matters

Beta glucan is the fraction of a mushroom the immune work is built around, and the panel lists it in its own right. It comes out of the organic immune blend, 1,510 mg a serving, and that blend carries cordyceps, reishi, royal sun agaricus, shiitake, maitake and turkey tail.

Cordyceps, Reishi and Turkey Tail Together

Cordyceps for stamina, reishi and turkey tail on the long immune horizon, shiitake, maitake and royal sun agaricus underneath them. Six mushrooms arriving on the same spoon means a daily scoop with a wide footprint, taken once, from a tub you only have to remember one of.

Micro-Cultured by Probiotic Fermentation

The mushroom mycelial biomass in here is fermented with probiotics before it ever reaches you, which is a slower and more expensive way to make a powder. It arrives partly broken down already, so your gut starts further along than it would with raw milled mushroom.

Gluten Free, Lactose Free, Corn Free

Gluten free, lactose free, corn free, non-GMO and vegan friendly, made in the USA. The organic prebiotic fiber blend does contain organic green tea extract, which naturally carries a small amount of caffeine, and that is on the panel too.

Organic Inulin and Fermented Ginger

Organic inulin, organic green tea extract and organic fermented ginger root make up the prebiotic fiber blend, and prebiotic fiber is the part your gut bacteria feed on. Each serving carries 6 grams of total carbohydrate of which 4 grams is dietary fiber, 14% of your daily value.

Built for Weeks That Run Long

This is for adults whose weeks stack up: long days, short sleep, travel, training on top of work. The vitamin C and the ginger are the fast half and the six mushrooms are the patient half, worked on an eight week horizon. Not for children, and not for anyone with a mushroom allergy.

What to Expect

Week 1

The first scoop lands and the quick parts move first. Vitamin C is topped up from that morning, and organic fermented ginger root brings warmth to a stomach that ate late and slept little. Underneath it the prebiotic fiber has already found the bacteria it feeds. You are someone who takes it now.

The fiber starts earning its keep. Four grams a scoop across a month is long enough for your gut to register the change, and this is the stretch where digestion stops announcing itself. The six mushrooms are banking quietly the whole time. Your morning now has a shape it did not have before.

Weeks 2 To 4

Weeks 4 To 8

Now the mushroom half compounds. Reishi, turkey tail and royal sun agaricus are the patient part of this tub, built on weeks rather than mornings, and this is the stretch where the scoop stops feeling like an experiment. Hard weeks still arrive and they take less out of you. You are covered in a way you were not.

Three months in, the scoop is no longer a decision. Vitamin C topped up daily, fiber your gut has come to expect, and six fermented mushrooms banked under all of it. Long days and short sleep keep coming and they cost you less than they used to. This is simply how you run.

Month 3 And Onward

Frequently Asked Questions

Right here on this page. CORTEX Fermented Mushroom Blend is sold direct through our own store, which is how the 90-day guarantee stays attached to your order and how we know the tub you receive came from us. It also means the price you see is the price, without a marketplace margin sitting on top of it.

Here is what is in it, and what each part is doing:

  • Vitamin C, 56 mg – 62% of your daily value, and it contributes to the normal function of the immune system and to the reduction of tiredness and fatigue
  • Organic Prebiotic Fiber Blend – organic inulin, organic green tea extract and organic fermented ginger root, the part your gut bacteria feed on
  • Organic Immune Blend, 1,510 mg – a mushroom mycelial biomass blend of cordyceps, reishi, royal sun agaricus, shiitake, maitake and turkey tail, micro-cultured by probiotic fermentation
  • Acerola Cherry Extract, 248 mg – where the vitamin C in this formula comes from, rather than a synthetic form
  • Total Beta Glucan – from the organic immune blend, and listed on the panel in its own right
  • Organic Cassava Maltodextrin – the carrier that lets the powder disperse into a drink instead of sitting on the surface

Gluten free, lactose free, corn free, non-GMO, vegan friendly and made in the USA. A serving is 6 g of total carbohydrate of which 4 g is dietary fiber, 14% of your daily value. The full Supplement Facts panel is printed on the tub.

Check with your doctor or pharmacist first, and there are three specific things worth naming rather than leaving to a general warning.

  • Blood thinners and antiplatelet medicines – ginger and reishi have both been reported to affect clotting, so this is a conversation to have if you take warfarin, clopidogrel or daily aspirin, or if you have surgery coming up
  • Immunosuppressant medicines – mushroom beta glucans act on the immune system, which is the opposite of what those medicines are prescribed to do. Ask before you start
  • Anything you take on a schedule – 5 grams of prebiotic fiber can change how quickly other things move through you, so leaving a couple of hours between this and a prescription is a sensible habit

The blend also contains organic green tea extract, which naturally carries some caffeine. Bring the label to whoever manages your prescriptions and let them make the call.

In a cool, dry place with the lid closed, out of direct sunlight, and keep the scoop dry when you put it back. Keep it out of reach of children. Do not use it if the seal is damaged or missing.

Take one scoop daily, mixed into food or drinks, or as directed by a health professional.

It goes into coffee, water, juice, yogurt, oats or a smoothie. Stir it into the liquid before you add anything else and it disperses rather than sitting on the surface.

If your diet is currently light on fiber, half a scoop for the first few days gives your gut time to catch up before you move to a full one. After that, the same time every morning is the part that matters most, because half this formula only does its work on repetition.

Thirty. The tub holds 210 grams and the serving is one 7 gram scoop a day, so one tub is one month. If you want to give the mushroom side of the formula the eight weeks it works on, plan for two.

Yes. This is for adults, and it is not intended for children.

Consult your health care practitioner before taking this or any other product if you are pregnant or nursing, taking medications, or have a medical condition. If you have a mushroom allergy, this is not for you. The interactions worth checking are set out in the medication question above. Keep out of reach of children.

If CORTEX isn't right for you, you're covered by our 90-day money-back guarantee. Return the product within 90 days of delivery and we'll refund you. If you have any questions along the way, our team will guide you through it.
