Vitamin C & beta carotene could help stack the deck against cognitive decline - German study
Main outcome measures were mild cognitive impairment among 74 mildly demented compared to 158 age- and gender-matched controls.
We found that blood vitamin C and beta-carotene concentrations were significantly lower in demented than in control persons even after adjusting for school education, intake of dietary supplements, smoking habits, body mass index, and alcohol consumption (3rd versus 1st tertile: OR: 0.29, 95% CI, 0.09–0.96 and 0.13, 95% CI, 0.03–0.55, respectively).
No associations were found for vitamin E, lycopene, and coenzyme Q10.
Our findings suggest an association of vitamin C and beta-carotene with dementia.
