📢 According to research by the National Institutes of Health in the United States, the optimal ratio of lutein to zeaxanthin is 10mg : 2mg, which is why you often hear about the "10:2" ratio.

📢 Lutein is one of over 600 natural carotenoids found in plants, belonging to the group of xanthophylls. It is a pigment essential for photosynthesis. While abundant in leafy green vegetables, the human body cannot synthesize it and must obtain it from food.

📢 Lutein is predominantly found in vegetables and plant-based foods such as lettuce, spinach, pumpkin, and peas.

📢 It acts as a potent natural antioxidant, protecting cells from damage caused by free radicals, and filters more than 90% of blue light wavelengths, thus helping prevent eye damage.

🆚 There are two main types of commercially available lutein: esterified and free form. Here’s a comparison:

🛑 Free Form:

• Predominant in natural foods.
• Smaller molecular weight, about half that of esterified form.
• Absorbed directly in the small intestine without requiring digestion, leading to higher average absorption rates (23% higher) and five times higher bioavailability compared to the esterified form.
• Studies published in various medical journals confirm its effective absorption by the eyes, increasing Macular Pigment Optical Density (MPOD).

🛑 Esterified Form (Lutein Esters):

• Larger molecular weight due to fatty components.
• Requires digestion with pancreatic enzymes to convert into free lutein and fatty acids before absorption.
• Less suitable for individuals with poor digestion or gastrointestinal issues.
