MCT Oil and Vitamin D3: what the published research says
PubMed indexes 4 records that name MCT Oil and Vitamin D3 together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to MCT Oil and Vitamin D3. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
4 studies naming MCT Oil and Vitamin D3.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“A qualitative change in the dietary fat source from 100% olive oil to equal parts of medium chain triglycerides, sunflower seed oil and olive oil and this same diet supplemented with vitamin D3 favoured digestive utilization of protein as recorded 1 month after surgery. However, the beneficial effects were maintained at 3 months only in resected rats given dietary fat in the form of 100% olive oil.”

Animal study
“The negative effects of distal small intestine resection on the nutritive utilization of phosphorus were not only palliated but significantly enhanced by supplementing the diet with vitamin D3 at a rate of 0.08 mg/100 g diet. This dose is within physiological limits, and favors phosphorus deposition in bone tissue.”
“-0.34 µg/mL (-1.71-2.15), p = 0.010). Liposomes may augment the bioavailability of vitamin A and cyclodextrins may strengthen the supplementation of vitamins D3 and E relative to MCT in pancreatic-insufficient CF but further studies are required to assess liposomal vitamin E (German Clinical Trial Register number DRKS00014295, funded from EU and Norsa Pharma).”

Comparative StudyAnimal study
“Although this effect was less notable at three months, nutritive utilization of Mg remained higher than in resected rats fed a diet lacking vitamin D3 supplementation. Dietary levels of vitamin D3 favored the deposition of Mg in bone tissue.”

Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers MCT Oil, Vitamin D3, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
