Popular questions
How much lutein per day?
There’s no established daily requirement; supplements commonly provide around 10 mg/day, and EFSA has set an acceptable daily intake of 1 mg/kg body weight/day for lutein (from Tagetes erecta) used as a food color (E161b).
What is lutein good for?
As a food additive it provides yellow–orange color; in the body, lutein (with zeaxanthin) concentrates in the retina, helping support macular pigment and normal visual function.
How much lutein and zeaxanthin should i take daily?
There’s no official RDA; a commonly studied regimen is 10 mg lutein plus 2 mg zeaxanthin per day (e.g., in AREDS2 formulations), though needs can vary—ask your clinician for personalized advice.
What does lutein do?
In foods it acts as a yellow–orange colorant (E161b); biologically it’s an antioxidant carotenoid that helps filter blue light in the eye.
What foods have lutein?
Leafy greens (kale, spinach), broccoli, peas, corn, and egg yolks are rich sources; smaller amounts occur in pistachios, zucchini, and kiwifruit.
Is titanium dioxide safe?
As a food color (E171), the EU no longer considers it safe and banned food uses in 2022 because potential genotoxicity of nano-sized particles could not be ruled out. Regulators in the U.S., UK, and several other regions still permit it within strict limits.
Is titanium dioxide bad for you?
Typical dietary exposure shows low acute toxicity, but ongoing uncertainty about DNA damage from very small particles led the EU to ban it in foods as a precaution. Occupational inhalation of TiO2 dust—not eating it—is the scenario most closely linked to cancer risk (IARC Group 2B).
Is titanium dioxide safe in sunscreen?
Yes—titanium dioxide is widely accepted as a safe, effective mineral UV filter in sunscreens when applied to skin. The main caution is avoiding inhalation of sprays or loose powders, since respiratory exposure to fine TiO2 particles is the concern flagged by IARC.
What is titanium dioxide used for?
In foods it serves as a whitening and opacifying agent in candies, chewing gum, bakery decorations, sauces, and supplement coatings. Outside food it is used heavily in paints, plastics, paper, cosmetics, and sunscreens for its brightness and UV-scattering properties.
What does titanium dioxide do?
It scatters light to create a vivid white appearance and hides underlying colors or textures, giving foods and tablets a uniform look. In personal care products it blocks and reflects UV light, contributing to SPF protection in mineral sunscreens.
