Energy drinks are widely consumed by teenagers and young adults to enhance focus and energy.

However, excessive consumption may lead to negative health effects, especially when they contain

preservatives like sodium benzoate. In this study, the concentration of sodium benzoate was

determined in four imported energy drink samples available in Asb'ah markets. The analysis was

conducted using a UV spectrophotometric method, which proved to be both simple and accurate. The

concentration of sodium benzoate in the samples ranged from 1361 to 1424.55 mg/L. The results

indicated that all tested samples contained sodium benzoate levels within the upper safety limits

established by the FDA

Abstract: Vitamin D deficiency is a public health concern affecting many individuals as it is highly prevalent in

all parts of the world. Recent studies have reported an association of vitamin D deficiency with cardiometabolic

alterations such as dyslipidemia. The study aimed to evaluate vitamin D and lipid profile levels among the Libyan

adult population and investigate the correlation of vitamin D deficiency with the alteration of lipid profile levels.

A cross-sectional study was conducted at Janzour Hospital among 193 subjects (107 males and 86 females) whose

ages ranged between 20 and 50 years over three months from Sept to Dec 2023. Vitamin D, cholesterol,

triglyceride, low-density lipoprotein, and high-density lipoprotein levels were estimated. The total mean vitamin

D levels were 8.31±4.74, 23.83±2.78, and 42.67±7.95 ng/dl for deficiency, insufficiency, and sufficiency,

respectively. The findings revealed significant alterations in cholesterol (increase), triglyceride (increase), LDLcholesterol

(increase), and HDL-cholesterol (decrease) among subjects who had vitamin D deficiency or

insufficiency as compared to subjects having vitamin D sufficiency. Vitamin D levels were negatively correlated

with cholesterol, triglyceride, and LDL cholesterol, and they were positively associated with HDL cholesterol.

The incidence of dyslipidemia is higher in the vitamin D deficiency group than in the insufficiency and sufficiency

groups. It is essential to frequently monitor lipid profiles among vitamin D-deficient individuals to avoid

subsequent disorders or damages associated with the alterations of lipid profile patterns.
