Welcome, friends of Dr. Michael Karlfeldt
For more than 30 years — beginning with a seven-year apprenticeship in the European naturopathic tradition — Dr. Karlfeldt has practiced one conviction: that the body, properly supported nutritionally, carries a remarkable capacity of its own. It's the philosophy behind The Karlfeldt Center in Meridian, Idaho, his True.Health TV series and HealthMade Radio — and it's the same conviction behind Haelan 951's 35 years of fermentation mastery. If Dr. Karlfeldt sent you here, you're among friends. Welcome.
When Your Body Is Asking for Everything, Give It the Most Advanced Soy on Earth.
Haelan 951 is not a supplement. It's a concentrated fermented food — whole organic soybeans transformed by a patented nitrogen fermentation process refined over 35+ years — delivering soy's full spectrum of studied immune-supporting compounds* in their most absorbable form.

Known and respected by leading integrative voices
For over three decades, Haelan 951 has earned its place in the rooms where serious nutrition is discussed — including among these practitioners and educators.
Some seasons of life demand everything your body can give.
Deep fatigue. Slow recovery. A body under more load than usual. When you're in one of those seasons — or walking through one beside someone you love — ordinary nutrition often isn't enough. That's when the depth of your nutritional reserves matters most.
Your immune system runs on nutrition
Immune cells are among the most metabolically demanding in the body. Feeding them well — deeply, consistently, absorbably — is foundational support, whatever else you're doing.*
Reserves get spent fast
Stress, age, and demanding seasons draw down the body's reserves faster than a standard diet rebuilds them. Concentration matters: one ounce of Haelan 951 is a dense, whole-food matrix — not an isolated extract.*
Absorption is everything
The best compounds in the world do nothing if they pass through unabsorbed. Fermentation pre-converts soy's key compounds into the forms research shows are absorbed faster and more completely.³ ⁴
Soy's immune-studied compounds — all of them, in one ounce
A 2024 review in Frontiers in Nutrition catalogued how soybean-derived compounds interact with the immune system's front-line cells — macrophages and dendritic cells — in laboratory research.¹ Haelan 951 delivers that full family, not one isolated fraction.
Genistein & Daidzein
Soy's flagship isoflavones, studied for how they modulate immune-cell signaling and inflammatory messenger production in macrophages and dendritic cells.*¹
Soyasaponins
Studied for their influence on macrophage behavior — including research on how they temper overactive inflammatory responses while supporting balanced immune activity.*¹
Lunasin
A soy peptide studied for its effects on immune-cell activation — including research observing enhanced phagocytosis, the process immune cells use to clear what doesn't belong.*¹
Bowman-Birk Protease Inhibitor
A soy protein studied alongside genistein for synergistic modulation of inflammatory pathways in immune-cell research.*²
Amino Acids, Zinc, Selenium & Phytosterols
The whole-bean foundation — essential amino acids, trace minerals and phytosterols that immune tissue depends on for everyday function.*
Fermentation Metabolites
Soy compounds are studied for supporting the gut microbiome's composition and diversity — and roughly 70% of immune tissue resides in the gut.*¹
Why the world's most advanced fermentation changes what soy can do
In raw, unfermented soy, the key compounds arrive locked — isoflavones bound to sugar molecules your gut must strip away before absorbing anything. Whether that happens efficiently depends on your gut bacteria, which is exactly what you can't count on when your body is already under load.
Fermentation does the unlocking before the first sip. Research in postmenopausal women found isoflavones from aglycone-rich fermented soy showed higher bioavailability than from unfermented soy³ — and aglycones are absorbed faster and in greater amounts.⁴
Haelan 951's process goes further than any soy food in history: a patented nitrogen fermentation, refined for 35+ years, that transforms whole, USDA-certified organic, non-GMO soybeans into the most concentrated fermented soy beverage in the world — isoflavones, saponins, peptides, protease inhibitors, amino acids and trace minerals, pre-digested and ready to absorb. This is why one 8-oz bottle is a serious tool, not a beverage.
Ordinary soy pills & powders
- Key compounds locked in glycoside form
- Absorption depends on your gut bacteria
- Isolated fractions — saponins & peptides discarded
- Often conventional or GMO soybeans
- Built for casual use, not serious support

- Compounds pre-unlocked into absorbable forms³ ⁴
- Fermentation does the conversion work for you
- Full matrix intact: saponins, peptides, BBI, minerals
- USDA-certified organic, non-GMO, whole bean
- One process, perfected for 35+ years
Rooted in 3,000 years of fermented soy — engineered for today
Long before laboratories could name genistein or lunasin, fermented soy anchored the traditional diets of Asia — miso, natto, tempeh — prized precisely in the seasons when bodies needed rebuilding.
Haelan Products began with that tradition in 1988 and asked a single question for 35 years: how much of the soybean's studied potential can one process unlock? The answer is Haelan 951 — trusted by health professionals for over three decades, and made the same way today: small batches, whole organic beans, one patented nitrogen fermentation.
Two protocols. One serious tool.
Haelan 951 is dosed by the ounce, and the right protocol depends on the season your body is in. This is exactly what the free consultation is for — every intensive protocol should be dialed in with guidance and alongside your healthcare team.
The Foundation Protocol
Two ounces daily — morning and evening, ideally on an empty stomach — for ongoing immune and nutritional support. One bottle lasts four days; six bottles carry you through most of a month.
The Intensive Protocol
For the seasons that demand the most: up to four ounces morning and evening for the first 90 days — a bottle a day. Undertaken with guidance, in coordination with your healthcare team.
Measure your immune resilience in 60 seconds.
- 7 quick questions, zero typing
- Your personal resilience score
- The Foundation or Intensive protocol matched to your season

The people who reach for it when it matters
"We keep Haelan in the fridge the way some families keep a fire extinguisher in the kitchen. When a hard season hits, we don't scramble."
"My practitioner suggested the intensive protocol during the hardest stretch of my life. It became the one part of my day that felt like actively doing something for myself."
"Yes, it's an investment. But I've spent more on cabinets full of capsules I couldn't tell were doing anything. This replaced all of it with two ounces a day."

"Fermentation is what sets this apart. It's the difference between swallowing a locked extract and drinking a whole-food concentrate whose compounds are already in the forms your body absorbs best."
What people ask us before they begin
Can I take Haelan 951 alongside what my healthcare team has me doing?
Haelan 951 is a fermented food made from whole organic soybeans — but any time your body is under serious care, your healthcare team should know everything you're taking. Bring the label to your next appointment, or book a free consultation and we'll help you prepare the right questions to ask them.
Which protocol is right for me?
The Foundation Protocol (1 oz morning + 1 oz evening) suits ongoing support. The Intensive Protocol (up to 4 oz morning + 4 oz evening for the first 90 days) is for seasons that demand the most — and it's a meaningful commitment, which is why we recommend a free consultation to size it correctly before you order.
Why does Haelan 951 cost more than other soy products?
Because it isn't comparable to them. Whole organic non-GMO soybeans, a patented nitrogen fermentation refined over 35+ years, small batches, and the full compound matrix — isoflavones, saponins, lunasin, Bowman-Birk protease inhibitor, amino acids and trace minerals — in concentrated, pre-unlocked form. On the Foundation Protocol it works out to under $2 an ounce of the most advanced fermented soy ever produced.
What does it taste like?
Strong, earthy, and fermented — closer to a traditional medicinal ferment than a flavored drink. Most people take it like an espresso shot or in a small glass of juice. The taste is the price of concentration without sugar or fillers.
I've heard conflicting things about soy. Should I be concerned?
Haelan 951 uses whole, USDA-certified organic, non-GMO soybeans in fermented form — the way soy has been consumed across Asia for 3,000 years. Its isoflavones are plant compounds, not hormones. If you have a soy allergy or a medical condition, talk with your healthcare provider first.
How should I store it, and how long does a supply last?
Refrigerate after opening. Each 8-oz bottle holds eight 1-oz servings: on the Foundation Protocol a bottle lasts four days (6 bottles ≈ three and a half weeks); on the full Intensive Protocol, a bottle a day (30 bottles ≈ a month).
When it matters most, give your body everything.
The most advanced fermented soy beverage in the world. Thirty-five years of mastery, one ounce at a time.
