A wide, minimalist editorial still life on a soft, warm-gray linen surface lit by gentle diffused morning window light. At center sit two identical small amber glass supplement bottles, one slightly in front of the other, with plain matte cream labels and no readable text. In front of them, two matching shallow ceramic dishes in muted sage green hold identical small ivory capsules. The capsules are nearly indistinguishable, which quietly suggests placebo versus active. Beside the dishes, a few wheat germ grains, a small cluster of aged cheddar-toned cheese shards, and a halved ripe mushroom hint at natural spermidine food sources. They are arranged with careful negative space.

On the left, a delicate balance scale in brushed brass sits perfectly level, its two small pans empty and even, as a subtle visual metaphor for "no difference." On the right, a neat open notebook with soft blurred pencil lines and a single sprig of dried eucalyptus lies beside a pair of thin round tortoiseshell reading glasses, suggesting older adults and memory without showing any people.

The background is a softly blurred pale oat-colored wall with a long gentle shadow cast diagonally across the scene from a window. The color palette is muted and modern: warm cream, sage green, amber, soft brass, and dusty terracotta accents. Shallow depth of field keeps the bottles and scale crisp while the edges melt into a creamy blur. The mood is calm, thoughtful, and quietly skeptical, like a trendy health and science journal feature. Fine film grain, a subtle matte finish, and a balanced asymmetrical composition leave open space in the upper right for headline overlay. Photographed from a slightly elevated three-quarter angle, high-end editorial photography style.

精胺能提升记忆吗？对 100 名老年人的 12 个月试验未显示优于安慰剂

精胺因自噬研究和动物实验被吹捧为大脑保护补剂。SmartAge 试验在 100 名主观认知下降的老年人中进行，每日约 0.9 毫克，持续 12 个月。主要记忆指标未能胜过安慰剂（差值 -0.03；P = .47），次要指标同样未见效。探索性分析提示炎症和言语记忆可能受益，但尚未得到确认。以下是该结果对考虑使用精胺补剂者的意义以及研究局限性的分析。
