Egg Yolk: A Nutrient Powerhouse
Many mistakenly discard the yolk due to fat and cholesterol fears, but this is where most of an egg’s micronutrients are found:

Vitamin D – supports calcium absorption and bone health
-
Vitamin E – powerful antioxidant protecting cells from damage
-
Vitamin K – essential for blood clotting
-
Folate – supports cell growth and DNA synthesis
-
B12 – aids red blood cell formation and neurological function
-
Choline – vital for brain development and liver function

Lutein and Zeaxanthin – antioxidants that protect eye health
Choline, in particular, is often under-consumed in modern diets. One egg provides about 147 mg, covering nearly 30% of the recommended daily intake for adults.
