Health Benefits
Origin & History
Natural habitat
Sambucus nigra agglutinin III (SNA-III) is a lectin protein isolated from elderberry seeds, extracted via affinity chromatography. It is biochemically distinct from other elderberry lectins, containing approximately 21% carbohydrate by weight.
“There is no information on the traditional or historical use of SNA-III in the available research. This lectin is primarily studied for its biochemical properties.”Traditional Medicine
Scientific Research
There are no human clinical trials, randomized controlled trials, or meta-analyses available for SNA-III. The existing literature is limited to basic biochemical characterization studies.
Preparation & Dosage
Traditional preparation
No clinically studied dosage ranges for SNA-III are documented. Consult a healthcare provider before starting any new supplement.
Nutritional Profile
Sambucus nigra agglutinin III (SNA-III) is a type-2 ribosome-inactivating lectin protein isolated from elderberry (Sambucus nigra) bark; it is a carbohydrate-binding protein that selectively recognizes sialylated glycoproteins and N-acetylneuraminic acid residues on cell surfaces, contributing to elderberry hemagglutinating and antiviral activity through interference with viral surface glycoprotein binding.
How It Works
Mechanism of Action
SNA-III specifically binds to particular carbohydrate structures on cell surfaces and within the extracellular matrix. This carbohydrate-binding specificity facilitates the agglutination of cells and interactions with glycoproteins. Through these binding activities, SNA-III influences cellular recognition and communication pathways, potentially modulating cell-to-cell adhesion and signaling processes.
Clinical Evidence
Current scientific literature presents limited human clinical research specifically investigating Sambucus nigra agglutinin III (SNA-III). Preliminary in vitro studies indicate SNA-III's ability to agglutinate cells and bind to specific carbohydrate structures. Definitive health benefits or therapeutic applications in humans remain unquantified, with no large-scale clinical trials available to establish efficacy or safety profiles.
Safety & Interactions
Due to the extremely limited human research on Sambucus nigra agglutinin III (SNA-III), comprehensive safety profiles and potential side effects are not established. Information regarding specific drug interactions, contraindications, or safety during pregnancy and lactation is currently unavailable. Individuals should exercise extreme caution and consult a healthcare professional before considering any use of SNA-III.

Frequently Asked Questions
What is Sambucus nigra agglutinin III (SNA-III)?
Sambucus nigra agglutinin III (SNA-III) is a type of lectin, a carbohydrate-binding protein, isolated specifically from the elderberry plant, Sambucus nigra. It is characterized by its highly specific affinity for certain carbohydrate structures, which dictates its biological functions.
What is the primary mechanism of action for SNA-III?
SNA-III's primary mechanism involves its specific binding to particular carbohydrate structures found on cell surfaces and glycoproteins. This binding activity enables SNA-III to agglutinate cells, meaning it can clump them together, and potentially influence various cellular communication pathways.
Where does SNA-III originate from?
Sambucus nigra agglutinin III (SNA-III) is derived from the Sambucus nigra plant, commonly known as elderberry. It is one of several lectins identified within this plant species, recognized for its distinct carbohydrate-binding specificity.
Are there any established health benefits of SNA-III for humans?
Currently, there is insufficient research to establish any specific health benefits of SNA-III for humans. Studies are primarily in vitro, focusing on its binding properties and cellular interactions, rather than quantifiable therapeutic outcomes in living organisms.
What is the current scientific understanding of SNA-III's safety and efficacy?
Scientific understanding of SNA-III's safety and efficacy in humans is very limited, as robust clinical trials are lacking. Preliminary studies mainly explore its biochemical properties and potential applications in cell biology, not its direct impact on human health or safety.
What food sources contain Sambucus nigra agglutinin III naturally?
SNA-III is naturally present in elderberry (Sambucus nigra) extracts and preparations, particularly in the fruit and bark. Whole elderberries and elderberry supplements are the primary dietary sources of this lectin compound. The concentration of SNA-III varies depending on the plant part used and extraction method employed.
What does current clinical research reveal about SNA-III's effectiveness in humans?
Clinical research on SNA-III in humans remains limited, with most evidence derived from in vitro and preliminary biochemical studies rather than controlled human trials. Available studies focus on characterizing its carbohydrate-binding properties and cellular interactions rather than establishing definitive health outcomes. Stronger human clinical evidence is needed before specific efficacy claims can be made.
Who should avoid or be cautious with SNA-III supplementation?
Due to limited safety data in humans, pregnant and breastfeeding women should consult healthcare providers before using SNA-III supplements. Individuals with lectin sensitivities, digestive conditions, or those taking immunosuppressive medications may warrant additional caution, though specific contraindications have not been formally established. Children and individuals with known plant protein allergies should also seek medical guidance before use.
