Abstract

Vitamin deficiencies remain a significant public health concern in Nigeria, where dietary diversity is often limited and micronutrient-enriched foods are scarce. This study, therefore, investigated the concentrations of fat-soluble and water-soluble vitamins in commonly consumed edible vegetable oils in Nigeria to assess their potential contribution to micronutrient intake. The vitamin content of ten commercial oil brands was determined using a UV–visible spectrophotometer. Results showed that vitamin E was the dominant component in all samples, with concentrations ranging from 4.26 to 6.56 mg/100 g. Sample V1 recorded the lowest level, while sample V8 had the highest. Vitamin C followed, with values between 0.61 and 1.17 mg/100 g, whereas other vitamins were detected in lower quantities: vitamin A (0.03–0.42 mg/100 g), vitamin D (0.02–0.11 mg/100 g), vitamin B₁ (0.009–0.024 mg/100 g), vitamin B₂ (0.008–0.016 mg/100 g), vitamin B₃ (0.38–0.71 mg/100 g), vitamin B₆ (0.25–0.34 mg/100 g), and vitamin B₁₂ (0.00–0.16 mg/100 g). The high levels of vitamins E and C indicate that vegetable oils are important supplementary dietary sources of antioxidants that may help reduce the prevalence of micronutrient deficiencies and associated health disorders in the Nigerian population.
