Targeted vitamin and mineral intake can blunt specific health effects of exposure to endocrine-disrupting chemicals, according to a research review focused on skin and pregnancy outcomes. The strongest signals come from vitamin A derivatives, vitamin B3 compounds, zinc, vitamin D, and omega-3 fatty acids, each tied to measurable improvements in published trials.
What the evidence shows by nutrient
A peer-reviewed review published in Archives of Dermatological Research examined the role of vitamins and minerals in rosacea, a chronic inflammatory skin condition linked in part to environmental and hormonal triggers. The authors, based at Eastern Virginia Medical School, the University of Miami, the University of Missouri-Kansas City, and Albany Medical College, searched PubMed, Web of Science, Science Direct, Google Scholar, and ClinicalTrials.gov for studies published between 1998 and 2023.
Vitamin A derivatives
Oral isotretinoin delivered the largest reductions in the review. Patients experienced a 90 percent reduction in lesions, with complete remission reported in 24 percent and marked improvement in 57 percent. The authors frame retinoids as a high-efficacy option, while noting long-term safety considerations associated with systemic use.
Vitamin B3 derivatives
Topical formulations showed consistent symptom relief. A 0.25 percent 1-methylnicotinamide preparation improved symptoms in 76.4 percent of patients (26 of 34 in the cited cohort), and a 1 percent NADH preparation improved symptoms in 80 percent. These compounds act through nicotinamide pathways that influence inflammation and barrier function.
Zinc, vitamin D, and vitamin C
A 5 percent zinc sulfate solution significantly reduced acne rosacea severity, with 40 percent of patients showing a moderate response and 60 percent showing a good response. Outcomes for vitamin D and vitamin C supplementation varied across the studies the review surveyed, and the authors call for standardized serum-level research to clarify who benefits most.
Omega-3 fatty acids
Omega-3 supplementation produced significant improvement in ocular rosacea, specifically xerophthalmia, in 64 percent of patients. This finding ties anti-inflammatory dietary fats to relief from a common rosacea complication affecting the eyes.
Why endocrine disruptors make this research relevant
Endocrine-disrupting chemicals are compounds that interfere with hormone signaling, and they are widespread in plastics, personal care products, pesticides, and food packaging. Researchers have linked this class of exposures to skin inflammation, reproductive changes, and metabolic shifts. Nutrients that modulate inflammation, oxidative stress, and hormone pathways, including vitamins A, B3, C, and D, plus zinc and omega-3s, sit in the same biological territory as the pathways these chemicals disrupt, which is why they are candidates for protective or adjunctive use.
Pregnancy and vitamin D: what a Cochrane review found
A separate Cochrane review updated in July 2024, led by researchers at Florida International University and the University of Liverpool, evaluated vitamin D supplementation during pregnancy across 10 included studies. The review applied a trustworthiness assessment and downgraded much of the evidence to low or very low certainty.
Across eight studies with 2,313 pregnant women, vitamin D supplementation showed possible reductions in severe postpartum hemorrhage (risk ratio 0.68, 95 percent CI 0.51 to 0.91; one study, 1,134 women, low-certainty evidence) and low birthweight (risk ratio 0.69, 95 percent CI 0.44 to 1.08; three studies, 371 infants, low-certainty evidence), though the upper confidence interval for low birthweight leaves open the possibility of harm. Effects on pre-eclampsia, gestational diabetes, preterm birth, and hypercalcemia remained very uncertain. Combining vitamin D with calcium, or with calcium plus other vitamins and minerals, did not produce clearer results.
The Cochrane authors emphasize that supplementation decisions during pregnancy should weigh the low certainty of the evidence against potential benefits and discuss options with a prenatal care provider.
Limits of the current evidence
Both reviews flag gaps. The rosacea review notes there are no established clinical recommendations for nutrient supplementation in this condition, and it calls for studies that measure baseline serum vitamin and mineral levels before testing supplementation. The Cochrane review removes 20 previously included studies to awaiting classification after trustworthiness checks, which illustrates how much pregnancy nutrition research still needs replication under stricter scientific-integrity criteria.
What someone can do with this information
Foods rich in the nutrients highlighted here include leafy greens and fortified dairy for vitamin D, fatty fish for omega-3s, citrus and peppers for vitamin C, lean meats and legumes for zinc, and orange vegetables for vitamin A precursors. Supplements can fill specific gaps but warrant medical guidance, especially during pregnancy or when using prescription retinoids. Anyone managing a diagnosed skin condition or planning supplementation during pregnancy should pair this research with a clinician’s review of their personal risk profile.
FAQ
Which vitamins and minerals have the strongest evidence for reducing effects of endocrine disruptor exposure?
A review of rosacea research identified vitamin A derivatives (notably oral isotretinoin), vitamin B3 derivatives (topical 1-methylnicotinamide 0.25 percent and NADH 1 percent), zinc sulfate 5 percent solution, and omega-3 fatty acids as the options with the most consistent positive outcomes.
Can vitamin D supplementation help during pregnancy?
A 2024 Cochrane review of 10 studies found that vitamin D during pregnancy may reduce the risk of severe postpartum hemorrhage and low birthweight, though evidence is low certainty. Effects on pre-eclampsia, gestational diabetes, and preterm birth remain unclear.
Are there official recommendations for using vitamins and minerals to treat rosacea?
No. The authors of the Archives of Dermatological Research review state that there are currently no established recommendations for nutrient supplementation in rosacea and call for studies that measure serum vitamin and mineral levels before testing supplementation.
