Metabolism (2)
- Effect of Ingestion of Medium-Chain Triglycerides on Substrate Oxidation during Aerobic Exercise Could Depend on Sex Difference in Middle-Aged Sedentary Persons
PubMed ID: 33374218
Short-term C8/C10 MCT ingestion increased fat oxidation during low-to-moderate exercise—direct metabolic effect.
- Supplementation of medium-chain triglycerides combined with docosahexaenoic acid improves cognitive function in Chinese older adults with mild cognitive impairment: A randomized double-blind, placebo-controlled trial
PubMed ID: 40044083
Large 12-month RCT of 14 g/day octanoic acid robustly increased serum ketones and produced modest cognitive benefits—strong metabolic (ketogenic) effect.
Gut health (2)
- Intestinal concentrations of free and encapsulated dietary medium-chain fatty acids and effects on gastric microbial ecology and bacterial metabolic products in the digestive tract of piglets
PubMed ID: 22397093
In piglets dietary MCFA raised gastric C8 levels and produced reproducible shifts in gastric microbiota (increases in Lactobacillus and other groups) — direct animal microbiome evidence.
- Effect of the probiotic strain, Lactiplantibacillus plantarum P9, on chronic constipation: A randomized, double-blind, placebo-controlled study
PubMed ID: 37019193
RCT in chronic constipation demonstrated improved transit and metagenomic/metabolomic shifts (increase in short-/medium-chain fatty-acid metabolism incl. caprylic pathways), supporting gut-balance effects indirectly.
Energy & Fatigue (1)
- Supplementation of medium-chain triglycerides combined with docosahexaenoic acid improves cognitive function in Chinese older adults with mild cognitive impairment: A randomized double-blind, placebo-controlled trial
PubMed ID: 40044083
High-dose octanoic acid markedly raised serum ketones over 12 months—ketones are an alternative brain/organ fuel and can support perceived energy.
Wellbeing (1)
- Supplementation of medium-chain triglycerides combined with docosahexaenoic acid improves cognitive function in Chinese older adults with mild cognitive impairment: A randomized double-blind, placebo-controlled trial
PubMed ID: 40044083
Large RCT reported modest cognitive improvements and systemic ketone increases with high-dose octanoic acid—meaningful wellness-relevant outcomes.
Nutrient uptake (1)
- Impact of Formulation on the Pharmacokinetics of Dutasteride: Results from Two Phase I Studies
PubMed ID: 27356530
Mono/diglycerides of caprylic/capric acids (formulation excipients) significantly altered dutasteride bioavailability—direct evidence caprylic derivatives can affect absorption.
Antimicrobial (1)
- Intestinal concentrations of free and encapsulated dietary medium-chain fatty acids and effects on gastric microbial ecology and bacterial metabolic products in the digestive tract of piglets
PubMed ID: 22397093
In piglets dietary MCFA changed gastric bacterial counts (increase in some groups, shifts in community) — in vivo microbiological impact of C8/C10.
Forms of Caprylic Acid
The form a label may print instead of Caprylic Acid. Each is a different substance with its own identifier, and none of them has research of its own — the studies are the ones on this page.
Similar by evidence
Supplements the same benefits carry qualifying findings for — a fact about the evidence graph, not a recommendation to swap.
