Quantum Digital Blue is an adult eye-nutrition supplement formulated to support the eyes’ filtering of high-energy blue light, with 20 mg of lutein and 4 mg of zeaxanthin per two-softgel serving.
Digital devices are part of daily life, and their high-intensity blue light can mean regular exposure for the eyes. Quantum Digital Blue is made for adults seeking eye nutrition that addresses this modern-use context. Its formula centers on lutein and zeaxanthin, alongside four additional nutrients, in a softgel format intended to be easy to swallow.
Quantum Digital Blue is formulated to help the eyes filter high-energy blue light through its lutein and zeaxanthin carotenoids. These natural plant pigments come from marigolds and are associated with the macula, an important area of the eye. The formula was developed for people who spend time around electronic devices, where excessive blue-light exposure over time may affect the eyes and sleep.
Each serving provides 20 mg of lutein, 4 mg of zeaxanthin, 100 mg of omega-3, 100 mg of curcumin, 67 mg of vitamin E, and 15 mg of zinc. The lutein-to-zeaxanthin amount forms a 5:1 ratio. Together, these ingredients make up the eye-nutrition formula rather than relying on lutein and zeaxanthin alone.
Take two softgels daily with food. A container has 60 softgels, providing 30 servings when used at this serving size. The softgels are specially created for ease of swallowing, making the format straightforward to include with a meal.
The formula was created by Dr. James Stringham, an eye nutrition expert who formerly worked as a research scientist in the Air Force Research Laboratory. It combines the carotenoids with curcumin, zinc, vitamin E, and omega-3 fatty acids for a multi-ingredient approach to eye nutrition.
Quantum Digital Blue suits adults looking to add carotenoid-based eye nutrition to a routine that includes regular digital-device use. Its two-softgel serving combines marigold-derived lutein and zeaxanthin with four other nutrients, and is taken daily with food.
