A multinational cross-sectional study on knowledge, attitudes, and practices towards magnesium supplements

Area of Science:

• Biochemistry
• Nutritional Science
• Public Health

Background:

• Magnesium is an essential mineral involved in numerous biochemical processes.
• Evidence on magnesium's role in bone, muscle, and cardiovascular health is conflicting.
• Magnesium supplements are increasingly popular for purported benefits in sleep and muscle spasm relief.

Purpose of the Study:

• To evaluate knowledge, attitudes, and practices concerning magnesium supplementation within Arab populations.
• To identify factors influencing the understanding and use of magnesium supplements in the Arab region.

Main Methods:

• A cross-sectional survey was administered across various Arab countries.
• Descriptive statistics and regression analyses were employed to analyze sociodemographic associations.
• Data normality was assessed using the Shapiro-Wilk test, with significance set at p < 0.05.

Main Results:

• 1,445 responses indicated low average knowledge scores (8.61 ± 5.9).
• High recognition of magnesium for muscle spasm (87%) and sleep (83%) benefits was noted.
• Only 31.8% used supplements, with neutral attitudes (mean score 3.02 ± 0.66) and limited medical consultation (36.1%).

Conclusions:

• A significant knowledge gap and neutral attitudes toward magnesium supplementation exist in Arab communities.
• Despite recognized benefits for muscle and sleep, public understanding remains limited.
• Targeted educational initiatives are crucial for promoting the rational use of magnesium supplements.
