Abstract

RATIONALE

There is potential for multivitamin supplementation to improve cognition in the elderly. This randomized, double-blind, placebo-controlled trial was conducted to investigate the effects of 16 weeks multivitamin supplementation (Swisse Women's 50+ Ultivite ®) on cognition in elderly women.

METHODS

Participants in this study were 56 community dwelling, elderly women, with subjective complaints of memory loss. Cognition was assessed using a computerized battery of memory and attention tasks designed to be sensitive to age-related declines to fluid intelligence, and a measure of verbal recall. Biochemical measures of selected nutrients, homocysteine, markers of inflammation, oxidative stress, and blood safety parameters were also collected. All cognitive and haematological parameters were assessed at baseline and 16 weeks post-treatment.

RESULTS

The multivitamin improved speed of response on a measure of spatial working memory, however benefits to other cognitive processes were not observed. Multivitamin supplementation decreased levels of homocysteine and increased levels of vitamin B(6) and B(12), with a trend for vitamin E to increase. There were no hepatotoxic effects of the multivitamin formula indicating this supplement was safe for everyday usage in the elderly.

CONCLUSION

Sixteen weeks ssupplementation with a combined multivitamin, mineral and herbal formula may benefit working memory in elderly women at risk of cognitive decline.

摘要

背景

多种维生素补充剂有可能改善老年人的认知能力。本随机、双盲、安慰剂对照试验旨在研究 16 周多种维生素补充(Swisse Women's 50+ Ultivite ®)对老年女性认知能力的影响。

方法

本研究的参与者是 56 名居住在社区的老年女性,她们主观上有记忆力减退的抱怨。认知能力通过计算机化的记忆和注意力任务测试进行评估,这些任务旨在测试与年龄相关的流体智力下降和语言回忆能力。还收集了选定营养素、同型半胱氨酸、炎症标志物、氧化应激和血液安全参数的生化测量值。所有认知和血液学参数均在基线和 16 周治疗后进行评估。

结果

多种维生素可提高空间工作记忆测量的反应速度,但其他认知过程没有观察到益处。多种维生素补充剂降低了同型半胱氨酸水平,增加了维生素 B(6)和 B(12)水平,维生素 E 呈上升趋势。该多种维生素配方没有肝毒性作用,表明这种补充剂对老年人日常使用是安全的。

结论

补充 16 周复合多种维生素、矿物质和草药配方可能有益于有认知能力下降风险的老年女性的工作记忆。
