Black Stuff for Microbiome Health (90 capsules)

You’re sure to love this black stuff, just as we do. The capsules contain natural extract from birch and the functional mushroom chaga, and they supply the body with a huge amount of humic acid, fulvic acid and polyphenols. They are literally loaded with trace elements and minerals of 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 fulfill 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 confirmed by an independent study of the biochemical laboratory of the University of Stradiņš in Riga. With each capsule, you send the body a small reinforcement of huge significance. 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.

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. The 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, the minerals easily enter the blood stream and then reach the cells and organs, where the body uses them effectively. This beautiful “cooperation” is technically called a chelate bond, and the chelated form of minerals has up to 20 times higher bioavailability than other inorganic forms of minerals.

A source of antioxidants

And now add to that urban smog, stress at work and free radicals. This is where antioxidants can play an important role, if we supply enough of them to the body. Black Stuff and the phenols with strong antioxidant effects it contains also help us with that.


Why do we 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 diet, 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 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 for your body. But your plans are being probably thwarted by poor bioavailability. What is it about?

Although you supply the body with the right amount of all the important minerals, they may be 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 can play its role.


What can be found in these capsules?

  • Humic acid (25 %) and fulvic acid (75 %): Both acids belong to the so-called humic substances. These are formed over thousands of years in the decomposition of plant biomass with the plant humification. Therefore, they contain a huge amount of minerals and other micronutrients.
  • Fulvic acid in the soil ensures the chelation of minerals and their transfer to living organisms. At the same time, it adds an electric charge to the essential minerals so that the organism can make the best use of them. On the contrary, it charges toxic metals with a neutral charge, making it difficult for them to pass into the body. Humic acid also accompanies essential micronutrients into the body and supports their full utilization. The producers of Black Stuff managed to obtain both acids by cold extraction from organic plants or from the wild.
  • Polyphenols: It is a group of chemical compounds and can be found naturally in plants. In them, they have various biological functions, adding flavor and color to some of them, participating in the formation of plant structure, protection against infections, UV radiation, pathogens and physical damage. Polyphenols also play an important role in the human body. They show high antioxidant activity and thus protect cells from free radicals and oxidative stress.


Unfortunately, we can’t tell you much about the health effects of this product. Our tongue is tied by current EU legislation, which does not allow us to state even one extra letter about food supplements. For more detailed information, look up some non-selling websites.


How can you use this product?

  • Take 1 capsule (0,5 g) a day, regardless of whether you are experiencing some acute health problem, or just want to maintain a healthy lifestyle
  • A higher dose makes no sense, as the body would not be able to absorb it anyway
  • You should treat yourself to a 90-day affair with Black Stuff at least twice or three times a year. That is the minimum time needed by the erythrocytes (essential body cells) for complete regeneration. However, taking into account how hectic modern life is, the quality of the air, and the deprived soil, we recommend taking Black Stuff all year round.
