Synopsis

Rating (out of 5): 4
DHA (docosahexaenoic acid) is an omega-3 fatty acid that plays a critical role in the development and function of the senses, particularly vision. Scientific evidence strongly supports the use of DHA in supporting the "Senses" body system, especially eye health. DHA is a primary structural component of the retina in the eye, making up about 30-40% of the fatty acids in the photoreceptor cells. Numerous studies have shown that adequate DHA intake is essential for normal visual development in infants, and deficiencies can result in visual impairment. In adults, observational studies and clinical trials suggest that higher dietary intake of DHA may reduce the risk of age-related macular degeneration (AMD) and support overall retinal health. The EFSA (European Food Safety Authority) and the FDA recognize the role of DHA in contributing to the maintenance of normal vision. While most evidence is strongest for early development, ongoing research also indicates potential benefits in preserving visual function with aging. Thus, scientific validation for DHA’s role in supporting the senses, especially vision, is robust.
