Elderberry Zinc Lozenges and Vitamin D3: what the published research says

PubMed indexes 8 records that name Elderberry Zinc Lozenges 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.

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Elderberry Zinc Lozenges 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.

The research

8 studies naming Elderberry Zinc Lozenges and Vitamin D3.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Low Serum Levels of Zinc, Selenium, and Vitamin D3 Are Biomarkers of Airway Inflammation and Poor Asthma Control: A Two-Centre Study.

Cureus · 2023 · PMID 37519504

“Vitamin D3 showed a strong positive correlation with zinc (r=0.4,p< 0.0001) and a negative correlation with inflammatory markers like SIgE and HsCRP. Conclusion Children with asthma had low zinc, selenium, and vitamin D3 levels, and were associated with airway inflammation and poor asthma control.”

Srivastava et al. · From the abstract

Names both Elderberry Zinc Lozenges and Vitamin D3 in its title.

Vitamin D3 and zinc synergistically induce regulatory T cells and suppress interferon-γ production in mixed lymphocyte culture.

The Journal of nutritional biochemistry · 2022 · PMID 35063658

Human subjects

“Lower concentrations of both vitamin D3 and zinc could be used for effective treatment, thus reducing possible side effects from vitamin D3 and zinc. Vitamin D3 and zinc in combination may be a promising and cheap option to treat dysregulated immune response in various conditions.”

Schmitt et al. · From the abstract

Names both Elderberry Zinc Lozenges and Vitamin D3 in its title.

Vitamin D3 transactivates the zinc and manganese transporter SLC30A10 via the Vitamin D receptor.

The Journal of steroid biochemistry and molecular biology · 2016 · PMID 27107558

Human subjects

“Zinc, manganese and vitamin D are important for bone metabolism and brain health. Future examination of a possible role for supplementation or chelation of zinc and manganese, alongside vitamin D3 administration, will further our understanding of its potential benefit in the treatment of specific illnesses, such as osteoporosis and Parkinson's disease.”

Claro da Silva et al. · From the abstract

Names both Elderberry Zinc Lozenges and Vitamin D3 in its title.

Antioxidative effect of vitamin D3 on zinc-induced oxidative stress in CNS.

Annals of the New York Academy of Sciences · 2005 · PMID 16179538

Animal study

“The involvement of glia-derived neurotrophic factor (GDNF) expression was excluded since vitamin D3 did not alter GDNF level in the infused substantia nigra at 24 h or 4 days after intranigral infusion of vitamin D3. Our results suggest that vitamin D3, independent of upregulation of GDNF expression, may acutely prevent zinc-induced oxidative injuries via antioxidative mechanisms.”

Lin et al. · From the abstract

Names both Elderberry Zinc Lozenges and Vitamin D3 in its title.

Effect to cholecalciferol and 1,25-Dihydroxycholecalciferol on the intestinal absorption of zinc in the chick.

The Journal of nutrition · 1980 · PMID 6251186

Research Support, U.S. Gov't, Non-P.H.S.Animal study

“When fed a diet adequate in cholecalciferol, more CaBP was present in the intestine of the zinc-adequate group than in the zinc-deficient group, possibly due to the greater rate of growth and therefore the greater need for calcium by the former group. These results suggest that cholecalciferol and its most active metabolite do not directly affect zinc absorption and, by inference, that the vitamin D-dependent transport mechanism is not involved in zinc homeostasis, or in the…”

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

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 Elderberry Zinc Lozenges, 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.
