Patent No. 1 (US20130231297A1): Improves Visual Performance

This patent describes an oral supplement formula containing astaxanthin, saffron, lutein, zeaxanthin, and European black currant extract, designed to support and improve visual function. It can help reduce eye fatigue, enhance clarity of vision, improve contrast and glare recovery, and speed up adjustment between bright and dark environments. These ingredients also act as natural blue light filters and antioxidants, helping protect retinal cells, nourish the macula (the area responsible for detailed vision), and support smoother signaling from the eyes to the brain.

Patent No. 2 (US9226940B2): Protects Eyes from Bluelight

This patent covers a method for supporting eye health by administering a specially designed blend of ocular antioxidants, such as lutein, zeaxanthin, vitamins A, C, E, minerals (like zinc and copper), and natural extracts. It’s intended for people with or at risk of vision conditions like hyperopia, presbyopia, or astigmatism, and aims to prevent, delay, or manage early age-related macular degeneration (AMD). Essentially, it helps protect the retina from damage caused by blue or ultraviolet light and oxidative stress, supporting clearer vision and preserving central sight longer.

Patent No. 3 (EP2498765A1): Improves Brain Memory

EP2498765A1 describes a formula designed to improve memory and mental focus. It’s built around compounds—often including plant-derived peptides—that help support brain function, making it easier to concentrate, learn, and recall information. The patent claims this ingredient blend can enhance overall cognitive performance by boosting alertness, attention span, and memory processing, helping users stay sharper and more mentally efficient.

Patent No. 4 (US10537604): Improves Brain Function & Activity

This patent covers a natural, herbal composition—often using tiger nut (Cyperus esculentus) extracts and mangiferin (a compound from mango leaf or bark)—that helps improve mental performance. When taken as a supplement, the blend can boost alertness, attention, concentration, and memory—similar to how caffeine works but without the crash or addiction. It’s especially effective in improving brain wave activity associated with focus and cognitive function, offering a smoother, more sustained energy and mental clarity experience

Patent No. 5 (EP3538085B1): Increases Rate of Neurogenesis

EP3538085B1 covers a specialized spearmint (Mentha spicata L.) extract—derived from proprietary plant lines—that, when taken orally (e.g. in capsules or powder), has been shown to increase neurogenesis, meaning it helps the brain grow new neurons, especially in the hippocampus. This boost in neuron formation supports better memory, learning, and overall cognition. Scientific studies cited in the patent demonstrated improved working memory and reduced oxidative stress in the brain after regular supplementation, making it a naturally‑derived way to promote brain health and mental clarity.
