$Approach: conceptual metaphor. Palette: D, bold color field. A single cracked ceramic-white bone-shaped column, like a femur section, stands upright at the center of a saturated mustard-yellow seamless backdrop. A thin, clean hairline fracture runs through its middle. Beside it, a small golden-amber glass dropper bottle sits tipped, with one droplet suspended just above the bone and not touching it, which suggests extra vitamin D that makes no difference. The camera is at a low three-quarter angle with a shallow depth of field. Hard, directional studio light from the upper left casts a crisp, long shadow across the yellow floor. The porous bone texture is visible in fine detail. A tiny electric green (#00e676) droplet reflection glints on the glass. The mood is skeptical, cool-headed and editorial.$

**Approach:** Conceptual metaphor. **Palette:** Bold color field (teal).

A single flexible garden hose, shot from a low three-quarter angle, lies coiled against a saturated teal seamless backdrop. One half of the hose is pale and wrinkled, with a stiff, cracked rubber texture and a visible kink. The other half is supple, glossy and smoothly curved. A thin stream of water arcs from the open end, catching the light. Soft, large-source studio light comes from the upper left and casts gentle, neutral grey shadows with no blue cast. A small electric green brass fitting, with a clean metallic sheen, sits where the two halves meet. The shallow depth of field blurs the coils in the foreground. The mood is quietly doubtful but curious, as if the result is promising and still unproven. There is no text anywhere in the frame.

**Approach:** Conceptual metaphor, in a bold color field palette (D).

A single ripe pomegranate, split open, on a saturated teal backdrop. It is the natural source of urolithin A's precursors. The camera sits at a slightly low three-quarter angle, close enough to show glossy, translucent arils. On the left half, the arils sit dull and tightly packed. On the right, a few arils hold a faint electric green glow, as if lit from within, hinting at a selective response in one place and not another. Behind the fruit, a thin copper wire runs across the frame and is unbroken on one side and fraying on the other, standing for arteries versus brain vessels. Soft, directional studio light from the upper left casts crisp shadows. Mood: curious, restrained, quietly hopeful. No text anywhere.
