Q: What is the use of zeaxanthin powder?
A: Zeaxanthin powder is used to support and protect eye health. As a primary macular carotenoid, it concentrates in the very center of the retina (the macula) where it acts as a powerful blue light filter and antioxidant, protecting delicate photoreceptor cells from damage. This helps to support visual acuity and protect against age-related eye health issues.
Q: What is the difference between lutein and zeaxanthin?
A: Lutein and zeaxanthin are dietary isomers found together in the eye, but they have different roles and distributions:
Distribution: Lutein is dominant in the periphery of the macula, while zeaxanthin is concentrated in the very center (fovea) where visual acuity is sharpest.
Function: Both filter blue light and act as antioxidants, but zeaxanthin is considered a more potent antioxidant in the most critical part of the retina. They work synergistically for comprehensive protection.
Q: What is the best source of zeaxanthin?
A: The richest natural source is goji berries (wolfberries). Other good sources include orange peppers, corn, saffron, and egg yolks. However, it is very difficult to obtain therapeutic doses from diet alone, making a high-quality zeaxanthin powder or supplement the most reliable and concentrated source.
Q: Which is better for eyes, astaxanthin or zeaxanthin?
A: They are not interchangeable; they protect the eye in different ways and locations:
Zeaxanthin is found inside the retina, protecting it from the inside from blue light and oxidative stress.
Astaxanthin cannot penetrate the retina but accumulates in the outer parts of the eye (e.g., ciliary body, extrinsic eye muscles), helping to reduce eye fatigue and support blood flow. For direct protection of the macula and central vision, zeaxanthin is essential. For reducing overall eye strain and supporting eye muscle function, astaxanthin is superior. They are complementary.
Q: What happens if you take too much zeaxanthin?
A: Zeaxanthin is extremely safe, even at high doses. The only known side effect of excessive intake (typically from very high-dose supplements over a long period) is a harmless, temporary yellowing of the skin called carotenodermia. This is not dangerous and will fade once the dosage is reduced. Always adhere to the recommended dosage on the product label.
