01 — The Molecule
One unique plant,
countless benefits
Panbonis® is a specialty feed ingredient containing a standardized level of glycosylated 1,25(OH)₂D₃, protected by glycosides from Solanum glaucophyllum. Once released, it interacts with vitamin D receptors in target tissues, supporting mineral absorption and genes involved in bone health, immunity, reproduction, and productivity.

Pathways
STANDARD PATHWAY
PANBONIS® PATHWAY
Activation Pathway
Vitamin D requires two enzymatic activation steps before it becomes biologically active — first in the liver, then in the kidney. It is only after both steps that the active form, 1,25(OH)₂D₃, is available to support calcium metabolism, bone health, immunity, and reproduction. What makes this more complex is that 25(OH)D₃ — the storage form measured in blood — does not automatically become active. Once formed in the liver, it can either be activated by 1α-hydroxylase in the kidney into 1,25(OH)₂D₃, or inactivated by 24-hydroxylase and excreted as calcitroic acid via bile. Measuring 25(OH)D₃ blood levels therefore reflects vitamin D storage — not activation. An animal can appear vitamin D-sufficient while the active form remains insufficient.
Physiological age gap
As animals age, kidney 1α-hydroxylase activity naturally declines — meaning the balance tips further towards excretion rather than activation, regardless of how much vitamin D is in the feed. The same limitation occurs when liver or kidney function is compromised by inflammation, mycotoxicosis, or metabolic stress. Panbonis®bypasses both activation steps entirely. Its glycosylated 1,25(OH)₂D₃ Molecule is cleaved directly in the intestine, delivering the active form where and when it is needed — independent of liver and kidney function.
THE TURNING POINT
Higher bioavailability. Greater mineral absorption.
With the slower release of the active metabolite, less is lost and more is delivered.
02 — How it works
From plant to receptor, how the Molecule works
Panbonis® is a specialty feed ingredient containing a standardized level of 1,25(OH)₂D₃, protected by glycosides from Solanum glaucophyllum. Once released, it interacts with vitamin D receptors in target tissues, supporting mineral absorption and genes involved in bone health, immunity, reproduction, and productivity.
STEPS
The glycosylated 1,25(OH)₂D₃ Molecule is consumed via feed and transits intact to the small intestine where specific enzymes are present.
Gut enzymes cleave the sugar molecule from the glycoside in a gradual process, ensuring slow, extended release of free 1,25(OH)₂D₃. No liver. No kidney activation required.
Free 1,25(OH)₂D₃ is immediately bioactive, engaging vitamin D receptors (VDR) and supporting performance
Excess 1,25(OH)₂D₃ is enzymatically inactivated and excreted as calcitroic acid via bile. Does not accumulate
Classical and non-classical effects, indexed.
From mineral metabolism to immunity, gut integrity and reproduction - many pathways.

Dairy Cows
Ruminant
Hypocalcaemia (milk fever) around calving is one of the most costly metabolic challenges in dairy production. Herbonis addresses this with a dedicated product.

04 — Origin
Natural before it became a trend.
Pioneers since day one.
A quarter century ago, when most of the industry relied on chemistry as a shortcut to scale, we chose nature. Our glycosylated 1,25(OH)₂D₃ Molecule, fully plant-based from Solanum glaucophyllum, set a new standard in animal nutrition: the only natural source of the active form of vitamin D, fully standardized and free from synthetic compounds.
