Benefit Evidence
Research sources
Immune support (5)
- Larch arabinogalactan effects on reducing incidence of upper respiratory infections
PubMed ID: 23339578
Large RCT found fewer participants developed common colds with daily larch arabinogalactan — preventive immune effect.
- Proprietary arabinogalactan extract increases antibody response to the pneumonia vaccine: a randomized, double-blind, placebo-controlled, pilot study in healthy volunteers
PubMed ID: 20796315
ResistAid (arabinogalactan) increased specific pneumococcal IgG responses in a vaccine-challenge RCT — strong adaptive-immune signal.
- Immunomodulatory effects of ResistAid™: A randomized, double-blind, placebo-controlled, multidose study
PubMed ID: 24219376
ResistAid (1.5 g/day) significantly increased tetanus IgG vs placebo, indicating antigen-specific immune enhancement.
- Difensil Immuno Reduces Recurrence and Severity of Tonsillitis in Children: A Randomized Controlled Trial
PubMed ID: 32498216
Multi-ingredient product including arabinogalactan reduced tonsillitis/fever in children, implying immune benefit though contribution of AG is uncertain.
- Use of Nutraceuticals in Elderly to Fight Inflammation and Immuno-Senescence: A Randomized Case-Control Study
PubMed ID: 36079732
Multi-ingredient nutraceutical containing arabinogalactan reduced inflammatory markers in elderly inpatients, consistent with immune-relevant changes (but not AG-specific).
Gut health (3)
- Randomised clinical trial: efficacy of a new synbiotic formulation containing Lactobacillus paracasei B21060 plus arabinogalactan and xilooligosaccharides in children with acute diarrhoea
PubMed ID: 22324448
Synbiotic containing arabinogalactan improved diarrhoea outcomes; plausible prebiotic contribution though formula included probiotics/XOS.
- Effect of arabinogalactan on the gut microbiome: A randomized, double-blind, placebo-controlled, crossover trial in healthy adults
PubMed ID: 34004416
Randomized crossover trial (15 g/day) produced clear microbiome composition changes (F/B ratio, Bifidobacterium trends) — strong prebiotic/mechanistic support.
- Proprietary arabinogalactan extract increases antibody response to the pneumonia vaccine: a randomized, double-blind, placebo-controlled, pilot study in healthy volunteers
PubMed ID: 20796315
ResistAid was used and produced immune effects; the product is marketed as a prebiotic and may have contributed via gut-immune axis.
Respiratory comfort (2)
- Larch arabinogalactan effects on reducing incidence of upper respiratory infections
PubMed ID: 23339578
Daily larch arabinogalactan reduced the number of people developing common colds over 12 weeks — evidence for respiratory prevention.
- Difensil Immuno Reduces Recurrence and Severity of Tonsillitis in Children: A Randomized Controlled Trial
PubMed ID: 32498216
Multi-ingredient supplement including arabinogalactan reduced tonsillitis and fever in children, indicating respiratory benefit (component attribution uncertain).
Digestive support (2)
- Randomised clinical trial: efficacy of a new synbiotic formulation containing Lactobacillus paracasei B21060 plus arabinogalactan and xilooligosaccharides in children with acute diarrhoea
PubMed ID: 22324448
Synbiotic shortened diarrhoea duration and reduced stool frequency in children — supports improved regularity in that context.
- Effect of arabinogalactan on the gut microbiome: A randomized, double-blind, placebo-controlled, crossover trial in healthy adults
PubMed ID: 34004416
Substantial microbiome and metabolite modulation with daily ResistAid implies effects on routine digestive function.
Wellbeing (1)
- Use of Nutraceuticals in Elderly to Fight Inflammation and Immuno-Senescence: A Randomized Case-Control Study
PubMed ID: 36079732
Multi-ingredient nutraceutical including AG reduced IL-6/CRP and improved self-reported wellness in elderly inpatients (multi-component intervention).
Bowel regularity (1)
- Randomised clinical trial: efficacy of a new synbiotic formulation containing Lactobacillus paracasei B21060 plus arabinogalactan and xilooligosaccharides in children with acute diarrhoea
PubMed ID: 22324448
Synbiotic shortened diarrhoea duration, improved 72-h recovery and lowered daily stool output — direct stool-health benefit in children.
