#nad+

4 articles
Approach: macro science. Palette: warm (amber and copper).

Extreme close-up of a freshly sliced king oyster mushroom stem and gill edge, shot at a slight 30-degree overhead angle with a macro lens and shallow depth of field. The pale cream flesh shows individual fibrous hyphae and glistening moisture beads. Warm low-angle golden light rakes across from the left, turning the gill ridges into amber and copper lines with deep honey-brown shadows. A single tiny droplet on the cut surface catches a pinpoint of electric green reflection, as if lit from a hidden source. Background melts into out-of-focus burnished orange and chocolate tones. The mood is quiet, intimate and investigative, with real organic texture and no text.

Vitamin “Kekekalan” dari Jamur Tingkatkan NAD+ pada Tikus Tua lewat Saklar H₂S

BY HELIX WARD ·

Ergothioneine, senyawa jamur yang dijuluki “vitamin kekekalan”, kini telah diuraikan mekanismenya. Dalam studi *Cell Metabolism*, tikus‑tua yang diberi ET berlari lebih jauh, ototnya memiliki vaskularisasi yang lebih baik, dan kadar NAD+ otot lebih tinggi. Efek ini ditelusuri kembali ke jalur hidrogen sulfida: CSE, persulfidasi, dan enzim cGPDH. Menghilangkan CSE atau cGPDH menghilangkan manfaatnya. Namun temuan ini masih terbatas pada hewan dan sel, dan dosis yang efektif pada tikus setara kira‑kira 10 kali lipat suplemen yang biasanya tersedia untuk manusia.

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 + Pterostilbene Meningkatkan NAD+ sekitar 40–90 % pada Uji Coba Manusia

BY NOVA CHEN ·

Apakah kapsul harian nicotinamide riboside dan pterostilbene dapat meningkatkan NAD+ pada orang dewasa yang lebih tua? Pada uji klinik pertama NRPT (Basis) melibatkan 120 peserta berusia 60–80 tahun selama delapan minggu. NAD+ dalam darah naik sekitar 40 % pada dosis rekomendasi dan hingga 90 % pada dosis ganda, dengan keamanan yang baik. Berikut rangkuman hasil, pelajaran dosis, serta hal‑hal yang tidak dapat disimpulkan dari studi ini.

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 Nicotinamide Riboside Harian Meningkatkan NAD⁺ pada Sel Darah Sekitar 60 % pada Lansia, Temuan Uji Coba Acak

BY DR. SYNAPSE ·

Uji silang 2018 yang dipublikasikan di *Nature Communications* menguji nicotinamide riboside dengan dosis 500 mg dua kali sehari (total 1.000 mg/hari) selama enam minggu pada orang dewasa sehat berusia menengah hingga lanjut. Suplemen tersebut dapat ditoleransi dengan baik dan meningkatkan NAD⁺ pada sel imun darah sekitar 60 % dibandingkan plasebo. Peneliti juga menemukan sinyal awal penurunan tekanan darah dan kekakuan arteri, yang mereka sebut sebagai hipotesis untuk uji coba lebih besar, bukan manfaat yang sudah terbukti. Artikel ini menjelaskan mengapa NAD⁺ diperkirakan menurun seiring usia, apa yang dilakukan dalam studi, serta apa yang tidak dapat disimpulkan mengenai hasil penyakit atau umur panjang.

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.

Keberhasilan Pertama NMN pada Manusia: 250 mg per Hari Meningkatkan Sensitivitas Insulin Otot Sekitar 25 % pada Wanita Pradiabetes

BY DR. SYNAPSE ·

NMN telah lama menjadi primadona pasar anti‑penuaan, namun bukti pada manusia masih minim sampai percobaan tahun 2021 dari Washington University yang dipublikasikan di *Science*. Pada wanita pascamenopause dengan prediabetes yang kelebihan berat badan atau obesitas, 250 mg NMN per hari selama 10 minggu meningkatkan sensitivitas insulin otot sekitar 25 %. Sinyal insulin otot dan gen‑gen yang berhubungan dengan perombakan otot juga meningkat, sementara kelompok plasebo tidak menunjukkan perubahan. Namun manfaatnya terbatas, dan studi tidak menunjukkan NMN menurunkan kadar gula darah atau membalikkan prediabetes. Berikut temuan percobaan, siapa yang dapat merasakannya, dan apa yang tidak berubah.
