Black Stuff - for microbiome health (30 capsules)

You are bound to love Black Stuff, as much as we do. These capsules contain natural birch and chaga extract, supplying our body with a huge amount of humic and fulvic acids and polyphenols. They are positively loaded with trace elements and minerals with excellent bioavailability. 

To give you a better idea, Black Stuff works like the most reliable carrier with a most luxurious first class. It helps to transport the minerals from your food and supplements to your cells and organs, where they can carry out their mission to the maximum and support the proper functioning of your body. On its way out, Black Stuff also picks up black passengers – substances that have no place in your body – and protects you from their harmful effects.

The antioxidants contained in Black Stuff help protect cells against free radicals and oxidative stress. This was also proven by an independent study done by a biochemical laboratory of Stradiņš University in Riga. With each capsule, you send the body a small reinforcement with a huge impact. You may suddenly find that you feel somehow more comfortable in your body, you may feel a greater appetite for all kinds of activities and sports, and everyday tasks will seem easier to accomplish.


Why do we also have Black Stuff at home?

It’s a sort of nutritional insurance for us. Even though we can also supply the body with the necessary substances from the food we eat, you know what it’s like… Sometimes, the day is hectic, we must make do, and we don’t pay so much attention to our meal plan. At the same time, we are well aware that modern agricultural practices deprive the soil of valuable micronutrients, which is why today the food on our plate has a different nutritional value than in the past.

Perhaps you enrich your balanced diet with food supplements, just to be sure, hoping to get all the necessary minerals. But your plans are probably thwarted by poor bioavailability. What is it about?

A source of antioxidants

Although you supply the body with the right amount of all the important minerals, they may come in a form that the body cannot use well. Minerals from food and supplements then pass through your gut and only a tiny quantity is absorbed into the organs and cells where they are needed. And this is where Black Stuff comes into play.

Nothing is wasted with the chelates from Black Stuff

In Black Stuff, the atoms of inorganic minerals are bound to an organic “carrier” – fulvic acid. These tiny molecules are highly absorbable. They immediately penetrate the cells, where the body uses them to the maximum. Fulvic acid shields the minerals with a protective barrier on their way through the digestive tract so that they do not start to decompose before they reach their destination. This way, they arrive at the wall of the small intestine, intact. From there, these minerals enter our bloodstream easily and are carried to cells and organs to be used effectively by the body. This beautiful “cooperation” is known as chelate bond, and such chelated form of minerals boasts a bioavailability up to 20 times higher that other inorganic forms of minerals.

And now add some urban smog, stress at work and the raging free radicals to the equation. This is where antioxidants can play an important role, if we supply enough of them to the body. Black Stuff helps us in this regard too, thanks to its high content of phenols with strong antioxidant properties.


What can you find in these capsules?

  • Humic (25 %) and fulvic (75 %) acids: Both acids belong to the so-called humic substances. These are formed over thousands of years in the decomposition of plant biomass during plant humification. Therefore, they contain a huge amount of minerals and other micronutrients.
    Fulvic acid ensures chelation of minerals in the soil and their transfer to living organisms. At the same time, it adds an electric charge to essential minerals so that the organism can make the best use of them. Toxic metals, by contrast, are chelated with a neutral charge, making it difficult for them to enter the body. Humic acid also accompanies essential micronutrients into the body and supports their maximum absorption. The producers of Black Stuff managed to obtain both acids by cold extraction from organically grown or wildcrafted plants.
  • Polyphenols: A group of chemical compounds found naturally in plants. They serve numerous biological functions. In some plants, they provide taste and colour, in some they play a role in the structure, and in others they help protect the plants from infections, UV radiation, pathogens, and physical damage. Even in the human body polyphenols show a wide range of effects.. They are characterised by high antioxidant activity, thus protecting our cells from free radicals and oxidative stress


Unfortunately, we can‘t reveal more about the health benefits of this product due to current EU legislation regarding dietary supplements. For more information, try googling non-eCommerce websites.


Suggested use:

  • Take 1 capsule (0.5 g) a day, whether you are experiencing acute health problems, or just want to maintain your healthy lifestyle.
  • A higher dose makes no sense, since the body would not be able to absorb it.
  • Treat yourself to a 90-day romance with Black Stuff at least 2 or 3 times a year. This is the minimum time required for our erythrocytes (essential cells of the body) to be restored completely. However, taking into account our modern hectic lifestyle, air pollution, and nutrient-depleted soil, we recommend taking Black Stuff year-round.
