Can maqui berries improve vision in older adults?
Maqui berries may offer some benefits for vision in older adults, particularly for those experiencing dry eye symptoms:
- Increased tear production: A study showed that consuming 60 mg of maqui berry extract daily for 4 weeks led to a significant increase in tear fluid production, which can help alleviate dry eye symptoms.
- Reduced eye discomfort: Participants using maqui berry extract reported a 57% reduction in bothersome eye-related discomfort after 4 weeks of use.
- Protection against oxidative stress: The high antioxidant content in maqui berries, particularly anthocyanins, may help protect retinal cells from oxidative damage.
- Potential benefits for age-related eye conditions: Some evidence suggests that maqui berry antioxidants may help reduce the risk of age-related eye diseases such as cataracts and age-related macular degeneration (AMD).
- Improved overall eye health: One study reported that people who included 60 mg of maqui berry daily in their diet experienced better vision in their old age.
While these findings are promising, it’s important to note that more research is needed to fully establish the effects of maqui berries on vision improvement in older adults. The current evidence primarily supports benefits for dry eye symptoms and general eye health rather than specific improvements in visual acuity or night vision.
