Our differences

We’ve made it our mission to create exceptional, nutrient-packed eye health supplements, crafted only from proven, high-quality ingredients.

No compromises
Extensive third-party testing and certifications

What you put in your body matters. Our supplements are formulated according to the highest standards and certifications, providing you with both health benefits and peace of mind.

As nature intended
Crafted from ingredients found in nature

Proven eye health nutrients such as carotenoids and antioxidants, found in everyday foods, can be hard to get enough of from diet alone. Our supplements include premium ingredients that resemble whole natural food to help enhance nutrient availability.

Based in science
Transparent claims about our ingredients

Partnering with leading clinicians and nutritionists, we focus exclusively on health claims where our ingredients have been shown to be beneficial to eye health. We don’t venture beyond the science.
