Our Story

Rooted in Ancient Wisdom, Perfected by Modern Science

Haelan 951 isn't just another health drink. It's the culmination of over three millennia of fermentation knowledge combined with cutting-edge nitrogen fermentation technology. Crafted from whole, organic, non-GMO soybeans through our proprietary nitrogen fermentation process, every bottle of nitrogen-fermented soy delivers concentrated phytonutrients from the whole fermented bean.

Grown the Right Way

Our soy is 100% organically grown.

Everything in Haelan 951 starts with the soybean, and we have never been willing to cut corners there. Our soy is grown organically in the remote highland fields of Mongolia, far from industrial farmland, from non-GMO seed and without the heavy herbicide use that is common in conventional soy farming.

Fermentation can only work with what it is given. It does not add quality; it reveals what is already in the bean. That is why we choose a specific soybean species for its natural nutrient density, let it grow at elevation in clean soil, and pick it by hand at peak freshness. It is slower and it costs more. We would not do it any other way.

Organic has never been a trend for us. It has been the standard since 1988, and it is something our family takes real pride in.

What is nitrogen-fermented soy?

Nitrogen-fermented soy

is a whole soybean food made by fermenting soy with selected cultures in a controlled, nitrogen-focused process. The cultures slowly break large soy proteins into smaller peptides and amino acids, while the bean's naturally occurring compounds stay in the food in changed forms.

Nitrogen is a building block of every amino acid, and amino acids are the building blocks of protein. Nitrogen fermentation centers on how the cultures work with the nitrogen-containing compounds in soy, so the fermentation is guided by the protein itself.

The result is different from open-air soy ferments like miso, tempeh and natto, and very different from unfermented soy milk or soy protein isolate. Nothing is extracted and nothing is stripped away. The whole bean is transformed by biology, given time.

Haelan 951 has been made this way since 1988. It is the nitrogen-fermented soy beverage that practitioners have recommended for more than three decades, registered with the FDA as a conventional food.

The Case for Whole-Food Nutrition

Modern Nutrition Isn't What It Used To Be

Even with a clean diet, many people aren't getting the level of nourishment their bodies need. Modern food systems, processing, and environmental stress can impact how nutrients are delivered and used. Haelan 951 is designed as a whole-food, fermented approach to daily nutrition: poured by the ounce, from four ingredients you can read.

Regulatory status: Haelan 951 is a nitrogen-fermented soy food intended for dietary and nutritional use. It is a conventional food, not a dietary supplement or drug.
Process Protocol

How Nitrogen-Fermented Soy Is Made

Our patented nitrogen fermentation process transforms organic soybeans into nitrogen-fermented soy, one of nature's most concentrated nutritional foods. Haelan 951 combines traditional fermentation practices with modern advancements to create a product trusted for decades by practitioners and health-conscious individuals.

Naturally Occurring Soy Compounds

What is in nitrogen-fermented soy, at the cellular scale

Soybeans naturally contain a distinctive set of plant compounds that food scientists have catalogued for decades. Fermentation changes the form of several of them. Here is what each one is, where it comes from, and why it is measured in whole fermented soy foods like Haelan 951, a nitrogen-fermented soy beverage.

Isoflavone molecules approaching a cell membrane
Compound 01

Soy Isoflavones

Genistein · Daidzein · Glycitein

Isoflavones are polyphenols found almost exclusively in legumes, with soybeans the richest common food source. In the raw bean they are mostly bound to a sugar (glycoside form). Fermentation converts many of them to the free aglycone form, which is why fermented soy foods such as miso, tempeh and natto are the classic dietary sources studied by researchers.

Class
Polyphenol (flavonoid)

Soy, chickpeas, red clover

Glycoside to aglycone
Soy peptides meeting receptors on a cell surface
Compound 02

Soy Peptides

Bioactive peptides · Lunasin

Peptides are short chains of amino acids released when soy protein is broken down. Fermentation and enzymatic digestion cut the large storage proteins (glycinin and conglycinin) into these smaller fragments. Lunasin, a 43-amino-acid peptide first isolated from soybean, is one of the most widely characterized soy peptides in the scientific literature.

Compound 03

Soyasaponins

Group A · Group B · DDMP saponins

Saponins are naturally foaming compounds made of a triterpene core attached to sugar chains. Soyasaponins are the family specific to soybeans, concentrated in the hypocotyl (the germ) of the bean. They contribute part of the earthy, slightly bitter character of whole-soy foods and are one of the reasons Haelan 951 tastes the way it does.

Bowman-Birk inhibitor protein structure
Compound 04

Bowman-Birk Inhibitor

BBI · Soybean protease inhibitor

The Bowman-Birk inhibitor is a small, stable protein found in soybeans and other legumes, named for the two scientists who isolated and characterized it in the 1940s and 1960s. It is classed as a protease inhibitor and is notable for surviving heat and digestion better than most proteins, which is why it is one of the most studied proteins in soy.

Class
Protease inhibitor protein

Soybeans, legumes
Property

Compound 05

Fermentation Metabolites

Organic acids · Free amino acids · B-vitamins

When yeast ferments soy, it produces its own set of compounds: organic acids, free amino acids and small amounts of B-vitamins, along with the aglycone isoflavones and peptides above. These metabolites are what distinguish a fermented soy food from an unfermented one, and they are the reason nitrogen fermentation, rather than open-air fermentation, is central to how Haelan 951 is made.

Want to go deeper? Read the history of nitrogen-fermented soy, or call (800) 542-3526.

What is nitrogen-fermented soy?

Nitrogen-fermented soy is a whole soybean food made through a controlled fermentation that centers on the nitrogen-containing compounds in soy. Selected cultures break soy protein into smaller peptides and amino acids, and the bean's natural compounds remain in changed forms. Haelan 951 is a nitrogen-fermented soy beverage made this way since 1988.

How is nitrogen-fermented soy different from miso, tempeh or natto?

Miso, tempeh and natto are traditional soy ferments made with open-air or traditional cultures and eaten as pastes or cakes. Nitrogen-fermented soy uses a controlled, nitrogen-focused process and, in the case of Haelan 951, is a liquid you pour by the ounce. Both start from the whole bean; the process and format are different.

Is nitrogen-fermented soy the same as soy milk or soy protein?

No. Soy milk and soy protein isolate are not fermented, and soy protein isolate is a processed extract of the bean. Nitrogen-fermented soy is the whole bean transformed by fermentation, with nothing extracted.

What is in Haelan 951 nitrogen-fermented soy?

The label lists four ingredients: water, organic cultured soy powder, yeast and salt. Naturally occurring soy compounds in the fermented bean include isoflavones, peptides, soyasaponins, Bowman-Birk inhibitor and fermentation metabolites.

Is the soy organic and non-GMO?

Yes. The soy in Haelan 951 is 100% organically grown from non-GMO seed in remote highland fields, and hand picked at peak freshness before fermentation.

Is nitrogen-fermented soy a supplement?

Haelan 951 is registered with the FDA as a low-acid canned food, which makes it a conventional food. It is not a dietary supplement or a drug.

How do you drink nitrogen-fermented soy?

A serving of Haelan 951 is 1 fl oz. The label lists 1 to 8 servings daily. Many people take it straight and chase it with water or juice; others mix it with Greens Powder+. Refrigerate after opening.

Where can I buy nitrogen-fermented soy?

Haelan 951 is sold directly by Haelan Products at haelan951.com, as a single bottle or on a Subscribe & Save plan.
