Approach: conceptual metaphor. Palette: bold color field.

A single AA-style cylindrical battery, shown as a real object with a bare metal cap and a plain unlabeled matte sleeve, stands upright on a glossy surface. It is photographed from a low three-quarter angle against a saturated tomato-red seamless backdrop. The battery is half-filled with a translucent amber liquid that visibly rises inside a clear glass cutaway section. A thin ribbon of electric green light (#00e676) wraps around its base like a charging band. Soft large-softbox light comes from the upper left and produces crisp highlights on the metal and a clean, slightly blurred red reflection beneath it. A second, shorter battery sits out of focus behind, nearly drained and empty, to suggest contrast. The mood is energetic, optimistic and precise, with a tactile product-photography look and shallow depth of field.

NR + pterostilben podiže NAD+ za ~40–90 % u ljudskom ispitivanju

BY NOVA CHEN ·

Može li dnevna kapsula nikotinamid‑ribozida i pterostilbena podići razinu NAD+ kod starijih osoba? U prvom ispitivanju u ljudima (NRPT, poznat pod imenom Basis) u kojem je sudjelovalo 120 osoba između 60 i 80 godina, dodatak je uziman osam tjedana. Razina NAD+ u krvi porasla je otprilike 40 % pri preporučenoj dozi i 90 % pri dvostrukoj, a povećanje je ostalo stabilno tijekom cijele studije. Nije zabilježena nijedna ozbiljna nuspojava. Evo što nam brojevi govore, koje su ključne pouke o doziranju i što ovaj rad ne može zaključiti.

Approach: conceptual metaphor. Palette: bold color field.

A single steel bathroom-style analog tape measure, pulled taut and wrapped around a ripe, glossy yellow-orange pear lying on its side, with the tape's tip locked at the same unmarked point, suggesting a waistline that did not shrink. The pear sits on a saturated magenta seamless backdrop, shot from a low three-quarter angle with a shallow depth of field, the stem sharp and the background softly blurred. Hard but slightly diffused studio key light from upper left casts a crisp, short shadow in deeper magenta on the surface. A tiny electric green sticky dot marks the tape's end, with no numbers or writing visible. Mood: playful, skeptical, deadpan, scientific restraint rather than hype.

Tjedni rapamicin tijekom godine: siguran, ali je li smanjio visceralnu mast?

BY REX MERIDIAN ·

Zanima li vas može li tjedni rapamicin smanjiti visceralnu mast i poboljšati zdravlje? Studija PEARL donosi iznenađujuće odgovore. Nakon 48 tjedana primijenjenog liječenja na zdravim osobama, primarni ishod – visceralna mast – nije pokazao promjenu, iako je profil sigurnosti bio sličan placebo grupi. Neki sekundarni pokazatelji, poput povećanja mišićne mase i smanjenja boli kod žena na 10 mg te boljeg osjećaja dobrobiti na 5 mg, upućuju na moguće koristi. Međutim, ti podaci su podskupinski i samoprijavljeni, lijek je bio pripremljen po mjeri, a nitko još nije dokazao da produljuje ljudski životni vijek. Evo što studija zaista pokazuje, a što ne.

Approach: the human outcome. Palette: natural.

Extreme close-up of a woman's eye and the delicate skin around it, shot from a slight three-quarter angle with a 100mm macro lens and a shallow depth of field. Her skin is a mature 50s complexion with fine crow's feet that are sharp and tactile, with visible pores and soft vellus hairs. Her gaze is relaxed and not at the camera, and the face is cropped so identity isn't the focus. Soft, directional window daylight rakes across the skin from the left to bring out the wrinkle texture, with gentle warm skin tones and a blurred leafy green background outdoors. A single glass of water with a faint dissolving powder swirl sits out of focus in the foreground, with a tiny electric green leaf highlight at the edge. The mood is calm, honest and quietly scientific.

2,5 g kolagenskih peptida smanjuje bore oko očiju za 20 % u 8 tjedna

BY NOVA CHEN ·

Kolagen je jedan od najtraženijih dodataka za ljepotu i dugovječnost, no vrlo malo proizvoda ima podatke iz placebo‑kontroliranih ljudskih studija. U studiji s 114 žena, starosti 45–65 godina, dnevna doza od 2,5 g specifičnog bioaktivnog peptida Verisol smanjila je volumen bora oko očiju za 20 % u odnosu na placebo nakon 8 tjedna. Biopsije su pokazale 65 % više prokolagena tip I i 18 % više elastina, dok je povećanje fibrillina od 6 % nije bilo statistički značajno. Učinak je ostao vidljiv još 4 tjedna nakon posljednje doze. Međutim, rezultati vrijede samo za taj brendirani peptid i za pregledanu populaciju, ne nužno i za druge kolagenske dodatke. Pogledajmo što rad zaista dokazuje, a što ne.

A bright, minimalist editorial still life on a pale warm-white stone surface, shot from a slightly elevated three-quarter angle in soft natural window light. At center, a small amber glass supplement bottle with a matte cream label, unbranded, sits beside a few loose white capsules. A pair of weathered hands in a light oatmeal linen sleeve, belonging to an older adult, rests gently near the bottle, with a ceramic mug of tea just out of focus. To the right, a clean glass vial and a delicate glass beaker filled with clear liquid catch the light, hinting at laboratory research without any futuristic touch. A small paper notebook with a handwritten simple line graph rising in a gentle curve lies open nearby, along with a sharpened pencil. Scattered at the edges are soft sprigs of dried eucalyptus and a few pale sage-green leaves, adding an organic note. A faint, abstract molecular diagram printed in muted teal ink on a card leans against the bottle, subtle and graphic. The palette is calm and modern: warm ivory, sage green, soft teal, muted amber, and touches of dusty peach. Long, gentle shadows fall across the surface, and the shallow depth of field blurs the background into creamy neutral tones. The composition leaves generous negative space on the left third for headline text. The overall feel is a trendy health and science journal: clean, airy, trustworthy, and quietly sophisticated, with fine film-like grain and true-to-life color. Ultra-detailed, 16:9 landscape.

1.000 mg nikotinamid‑ribozida dnevno podiglo NAD⁺ u krvnim stanicama za oko 60 % kod starijih odraslih osoba, prema randomiziranom istraživanju

BY DR. SYNAPSE ·

Kros‑over studija iz 2018. godine objavljena u *Nature Communications* testirala je dozu od 500 mg nikotinamid‑ribozida dva puta dnevno (ukupno 1 000 mg/dan) tijekom šest tjedana na zdravim sredovječnim i starijim osobama. Suplement je bio dobro podnošljiv i povećao je NAD⁺ u imunološkim krvnim stanicama za otprilike 60 % u odnosu na placebo. Istraživači su također zabilježili prve naznake smanjenog krvnog tlaka i arterijske krutosti, no to su samo hipoteze za buduća ispitivanja, a ne dokazane koristi. Članak objašnjava zašto se smatra da NAD⁺ opada s godinama, što je studija pokazala i što nam ne može reći o ishodima bolesti ili dugovječnosti.

A softly lit editorial still life on a pale oat-colored linen surface, shot from a slightly elevated three-quarter angle in a wide landscape frame. At center-left, a small matte white ceramic dish holds a modest pile of fine off-white powder, with a tiny brushed-brass measuring spoon resting beside it. Next to the dish stands a minimalist amber glass supplement bottle with a plain cream label and no readable text. A few capsules spill casually across the linen, some translucent and some opaque ivory.

On the right side of the composition, a ripe blood orange cut in half and a handful of raw almonds sit on a light ash-wood board. A sprig of fresh rosemary adds a muted green accent. A sheer glass of water catches the light and throws a soft, rippled caustic pattern across the fabric.

In the background, out of focus, a woman's hand in a soft sage-green knit sleeve rests near a ceramic mug. This suggests a calm morning routine without showing a face. Behind her, a tall window casts diffused, golden-hour light from the upper left, with gentle shadows and a creamy, shallow depth of field.

The palette is warm and restrained: oat, ivory, terracotta, sage, and amber, with a single pop of coral from the blood orange. A thin, abstract line of muted terracotta paint, like a brushed arc, sweeps across the upper right background. It subtly evokes a rising curve without becoming a literal chart.

The mood is calm, trustworthy, and contemporary, like a premium wellness and science journal feature. The image has crisp focus on the powder and bottle, natural film-like grain, soft contrast, and generous negative space in the upper third for headline overlay. It looks like a high-end editorial photograph with no text, logos, or futuristic elements.

Prvi ljudski uspjeh NMN‑a: 250 mg dnevno povećalo osjetljivost mišića na inzulin za oko 25 % kod predijabetičkih žena

BY DR. SYNAPSE ·

NMN je dugo bio zvijezda trenda za dugovječnost, ali dokazi na ljudima bili su oskudni sve dok nije objavljena studija Washington Universityja u časopisu *Science* 2021. godine. Kod žena u postmenopauzi s predijabetesom i prekomjernom tjelesnom težinom ili pretilošću, 250 mg NMN‑a dnevno tijekom 10 tjedana poboljšalo je osjetljivost mišića na inzulin za otprilike 25 %. Signali inzulina u mišiću i geni povezani s remodeliranjem mišića također su se poboljšali, dok u grupi s placebom ništa nije promijenjeno. Međutim, korist je bila ograničena i studija nije pokazala da NMN snižava razinu šećera u krvi ili preokreće predijabetes. Evo što je studija otkrila, na koga se odnosi i što nije promijenila.

A wide, softly lit editorial still life on a pale travertine surface. In the center-left, a halved ruby-red pomegranate sits open, its glossy arils spilling in a loose cluster onto the stone. Beside it are a few cracked walnut halves and a small matte ceramic dish holding a pinch of fine cream-colored powder. A single aril catches a bright highlight near the foreground. In the soft-focus background, a sheer linen curtain filters warm morning sunlight, which casts long, gentle shadows across the scene.

On the right side, an elegant older woman's hand, seen only from the wrist down, rests lightly on the surface next to a minimalist glass of water. Her skin shows natural texture and warmth. A slim sprig of dried olive branch and a folded sage-green napkin add quiet, organic accents.

The palette is restrained and modern: deep garnet red, warm walnut brown, oat beige, soft sage, and creamy off-white. The composition leaves generous negative space on the upper right for title text. The depth of field is shallow, with crisp focus on the pomegranate and a creamy bokeh falloff. The lighting is natural, diffused, and slightly golden, in the style of a high-end wellness magazine or a contemporary science and nutrition journal. The mood is calm, clean, and quietly authoritative. The finish is photographic, with fine grain, subtle matte tones, and a premium editorial feel.

Urolithin A, postbiotik od naranče, pokreće mitofagijski potpis kod starijih osoba

BY DR. SYNAPSE ·

Urolithin A je molekula koju crijevne bakterije pretvaraju iz polifenola naranče i oraha, a poznata je po tome što je obnavljala mišiće kod starijih životinja. Prvo kliničko ispitivanje na starijim osobama pokazalo je da je siguran, bioraspoloživ i da može pomaknuti mitohondrijske biomarkere pri dozama od 500 do 1 000 mg dnevno. Studija, koju je sponzorirala tvrtka iza Mitopurea, otkrila je molekularni potpis poboljšanog mitohondrijskog zdravlja u mišiću. Međutim, rad je bio mali, kratak i mjerio je samo biomarkere, a ne snagu ili dugovječnost. Evo što podaci zapravo pokazuju, kome su namijenjeni i gdje trenutni dokazi završavaju.
