A wide, editorial-style still life photographed from slightly above on a pale oak surface in soft morning window light. At the center, a small matte white supplement tub with a plain, unlabeled front sits tipped on its side, spilling a modest pile of fine white powder across the wood. Beside it, a wooden scoop rests in the powder, and a few white capsules are scattered in a loose arc. To the left, a clean glass of water catches the light and throws a delicate caustic shadow. To the right, a neatly arranged group of whole foods sits in contrast: two brown eggs, a small wedge of salmon fillet on parchment, a handful of raw almonds, and a sprig of rosemary. A matte black steel dumbbell handle is partly visible at the top edge of the frame, grounding the fitness theme. In the lower foreground, a slim, open linen-bound notebook holds a hand-drawn line graph with a single line trending gently downward, a thin ink pen lying across the page. The palette is muted and warm: cream, soft sage green, pale oak, charcoal accents, and a touch of terracotta from a ceramic dish holding the almonds. Shallow depth of field blurs the background, a softly lit minimalist kitchen counter with a hint of a plant leaf. The mood is calm, thoughtful, and scientific without being clinical, like a cover image for a contemporary health and nutrition journal. Natural shadows, subtle film grain, and generous negative space on the upper left leave room for a headline overlay. Crisp focus on the powder and scoop, with refined, understated composition and no text or logos visible.

D-Aspartic Acid Lowered Testosterone at 6 g/Day in Trained Lifters

D-aspartic acid is marketed as a natural testosterone booster, but in a controlled trial of 24 resistance-trained men, 6 g/day actually lowered both total and free testosterone. The 3 g dose found on many labels did nothing measurable. A later 3-month trial found no strength or muscle advantage either. Here is what the study found, why trained men may respond differently from sedentary ones, and where your supplement money is better spent.
