All about maple > Maple syrup > Health and nutrition

Maple syrup contains significant amounts of minerals, including zinc and iron, and compounds found in B complex vitamins, mostly thiamine. Just 50 milliliters (about 3 tablespoons) of maple syrup provide 4% of the daily recommended amount of calcium, 3% of potassium, and 2% of daily magnesium and riboflavin requirements. Recent studies have also shown that maple sap contains phenolic and flavonoid acids with important antioxidant and organoleptic properties.
