Approach: conceptual metaphor. Palette: D, bold color field.

A tall glass of bright orange-gold liquid sits in the center of the frame, filled to the brim and overflowing down its sides, shot at a slight low angle. Beside it, a sealed, empty glass cylinder with a thin glass wall stays bone dry. A clear glass barrier stands between them, so the flow clearly never crosses. The backdrop is a saturated tomato-red seamless paper, with a glossy red surface reflecting both vessels. Hard, directional studio light from the upper left throws crisp, warm-neutral shadows and bright highlights along the glass rims and liquid droplets. One small electric green ring sits at the base of the empty cylinder as a subtle accent. Mood: tense, ironic, clean and editorial. Photorealistic, shallow depth of field, no text or labels.

Vaš CoQ10 dopire do krvi, ali ne i do mitohondrija

BY NOVA CHEN · 31. lis 2026.

Nedavno je ljudsko kliničko ispitivanje podvrglo iznimno popularni suplement za dugovječnost detaljnoj provjeri uz mišićne biopsije. Rezultati su nepovoljni za marketing: kod 40 zdravih starijih osoba (prosječna dob 74 godine) 400 mg CoQ10 dnevno tijekom 12 tjedana podiglo je razinu u krvi, ali nije promijenilo razinu u mišiću ni u mitohondrijama. Funckija mitohondrija, VO₂max, kontrola glukoze i tjelesna kompozicija također su ostali nepromijenjeni. Studija je mala, kratka i provodila se na robustnoj starijoj populaciji, a glavni autor je savjetnik za tvrtku Pharma Nord. Evo što je otkrila, što ne može zaključiti i kome bi ipak razgovor o CoQ10 mogao biti koristan.

**Approach: Lab in action. Palette: D, bold color field (teal).**

Overhead three-quarter angle on a gloved hand holding a small insulin-style syringe over a tray of mouse-muscle tissue samples. The nitrile glove is bright white, and the backdrop is a saturated teal lab bench surface with a soft sheen. Tiny clear microtubes sit in a rack, and a few contain a faint amber liquid. One thin electric green cap on a tube is the only green accent. The lighting is bright, even studio-like lab light with crisp, soft-edged shadows and a gentle highlight on the syringe barrel and a single hanging droplet at the needle tip. The depth of field is shallow, so the background tubes blur into teal. The mood is precise, focused and quietly hopeful, with no readable text or labels anywhere.

Jedna doza SS‑31: stare mišićne mitohondrije počinju raditi kao mlade za sat vremena

BY HELIX WARD · 22. lis 2026.

Jedna injekcija, šezdeset minuta – mitohondrije u starim štakima počele su proizvoditi energiju poput one kod mladih životinja. Tako glasite iz studije iz 2013. godine u časopisu *Aging Cell* koja je ispitivala peptid SS‑31 (elamipretid). Važno je naglasiti da su to rezultati na miševima, a ne na ljudima.

Approach: the human outcome. Palette: bold color field, mustard yellow.

A tight, low-angle side view of an older man's muscular calf and thigh mid-leg-press or seated leg extension, shot from knee level. His weathered, sinewy skin shows fine hair and visible tendon definition, and his hands rest on the knee. He wears a plain charcoal athletic short and a worn white sneaker. The backdrop is a seamless saturated mustard-yellow wall, with a matte black gym machine frame cutting diagonally through the frame. Soft, directional studio light from camera left creates gentle highlights on the quadriceps and a warm shadow. A small electric green resistance band is looped around his ankle as the only green accent. The face stays out of frame. The mood is determined, strong and quietly hopeful, with a shallow depth of field and a crisp editorial feel.

15 g kolagenskih peptida: dvostruko veći dobitak u snazi nogu kod starijih muškaraca

BY HELIX WARD · 20. lis 2026.

Internet tvrdi da je kolagen beskoristan za mišiće, ali randomizirano ispitivanje na starijim muškarcima s sarkopenijom pokazuje da je situacija složenija. Nakon 12 tjedana treninga otpora, muškarci koji su uzimali 15 g kolagenskih peptida dnevno dobili su oko 45 % više mišićne mase (+4,2 vs +2,9 kg) i više od dvostruko veći porast snage nogu u odnosu na skupinu s placebo‑silicom. Ispod su ključni nalazi, moguće mehanizmi djelovanja i praktične preporuke.
