In addition, when Rhodiola rosea capsules were used to treat patients with Alzheimer’s disease, it was found that Rhodiola rosea capsules (taking two capsules three times a day for 63 days) could significantly increase the ADL score and the levels of SOD and GSH-Px, suggesting that the supplemental treatment of Alzheimer’s disease with Rhodiola rosea capsules has better efficacy and higher safety [194]. This evidence concerns the gene SOD1 and early-onset autosomal dominant Alzheimer disease.
