ReaLBuild® is a clinically studied formula that helps maintain platelet and white blood cell counts.


Many substances in the environment have a potentially destructive effect on white blood cells, the main agents of the immune defenses.1

As a biochemist, Dr. Mirko Beljanski knew that any cell, in order to duplicate, needs special and specific “primers” to catalyze the process of cell duplication. Besides this initial step of cell division, there is no other intervention by these RNA-fragments. All organisms proceed this way.2, 3

Dr. Beljanski prepared short fragments of RNA primers from Escherichia coli K-12 (a strain recognized as totally innocuous)4 according to the model of what the healthy body provides for cell multiplication in a selective and specific manner.5

These RNA fragments do not interfere with other cells. They simply support the body’s immune system to help boost the cells, which naturally enhance the generation of white blood cells and platelets.6,7*

Contents: 10 units per bottle. Each serving of ReaLBuild® contains 20 mg ribonucleic extract of Escherichia coli K-12.

Suggested Daily Intake as a Dietary Supplement: Take the contents of one unit of ReaLBuild® every other day or as recommended by your health care practitioner. Pour the contents of one unit under your tongue and let it dissolve slowly. Do not exceed the recommended daily dosage.

Best Conservation Method: Keep the bottle in a dry and cool environment. Do not freeze. Close the lid after use.

Caution: The use of ReaLBuild® is not recommended for people following a treatment with Benzodiazepine or when an aplasia is sought in the case of certain cancer treatments. Regular intake of magnesium is recommended.

From our laboratories to your hands, quality control standards are continuously applied to assure you a product worthy of the Beljanski® name and reputation.

To me, Real Build is very reliable, it truly rebuilds me. I stick with it because it is plant-based and I'm not involving myself with a chemical-based product for my long-term care. As I got to know the product, I came to a place where I regulate for my Verified Purchase
I have been taking real build for 10 years+ on and off. Now, I try to be as consistently on, as possible. I found out what the difference was by repeated drop - offs of the product. Hence, why I kept going back. I talked about this because it is a unique product that needs some getting to know. Such a new and different approach to home care, I needed to learn about my reactions to it. This developed to be, the fact that if I didn't take it my health dropped and struggled. When I took it, I came back to life, I function better at exercising, cooking, endurance-related things like laundry and even shopping. Better thinking, less fog, less sluggishness. When I take them I hear myself saying, I need to go get the energy that I can't give myself. I feel it protects me from flus, too, boosting my immune system, when I can't do that, either. When I take real build, my nails grow faster, my hair is stronger, I feel more - up. I literally feel that when I take my dose, the frags go straight to my weakest places first. If I have a headache, I feel activity in my head, first when I broke my toe, I felt the frags energized my toe injury first. I always feel them helping my adrenals. Pulling me together. I stand straighter. Those are my side-effects. If I take too much, I feel like my leg muscles want to run, except I know from my injuries I can't support running. So, I take less to be at the same Pace as my healing. I don't know where I'd be without them, honestly. I am a happier person, relieved I have help I can manage. They have really pulled me out of the mud. My condition, adrenal insufficiency, was due to a trauma my mother was in while she was 8 months pregnant with me and my twin sister. We weren't expected to live. My father and grandfather died in a boat accident, and my mother went into such despair her adrenal glands strained not only her body, but the stress used mine and my sister's adrenal glands, too. There was no separating us from her. We didn't find out how this affected our adrenals until we were about 40 years old, going to natural-based doctors. Our mother died and the stress of that on my sister and I put us into an adrenal crisis in 2004, which was when we started our journey to find us the right kind of medical help. Around 2007 , the Beljanski family put out a book on RNA fragments and stem cell therapy. I read the book, it made so much sense, I started my own journey with the fragments. If your mother was in trauma while you were in utero, your adrenals may have been strained, too? Something to consider. It's not easy at all to treat adrenal glands. It took me a very very long time to figure out why my system was so sluggish. That's why I relate the story here. I know I may never fully regain my adrenal functioning, but I am thrilled I found something as reliable as real build to help me live on a long-term basis. It's that bit of help at the right time any product developed by the Beljanski family, is very worth your time, money, and physical investment. In my opinion, they are a Class - A company; products, people, everything.

Real Build makes a real difference
I've been taking often Real Build for the last years, and, in that time, have noticed a marked improvement in my general well-being. I have not needed to take a single day off work due to illness, and, in the few times that I have caught a cold, it has not affected me much, it has not lasted long, and it has not stopped me from getting on with my day.
Real Build is easy to take and has a sweet flavour. I would highly recommend it to anyone who wants to give their immune system a boost.
