A bright, airy editorial flat-lay shot from slightly above, on a soft warm-white linen surface with gentle natural window light and long, soft shadows. Two small ceramic dishes sit side by side at the center. The left dish holds a single small capsule in muted terracotta. The right dish holds one small capsule in the same color, with a noticeable empty space beside it to suggest rhythm and spacing. Between them lies a minimalist wooden calendar block or a row of seven small round ceramic discs in alternating tones, dusty rose and cream, evoking an every-other-day pattern. Around the dishes are fresh, iron-rich foods arranged with restraint: a halved blood orange, a few deep green spinach leaves, a small scattering of pumpkin seeds, and a sprig of parsley. A folded sage-green athletic towel and a slim, modern water bottle sit at the upper edge, hinting at women who train. A matte ceramic mug of herbal tea sits at the right with a faint curl of steam. A small notebook with a pen lies open at the lower left, its pages blank, suggesting lab results and tracking without any legible text. The palette is soft and cohesive: warm cream, dusty rose, terracotta, sage green, with small accents of deep coral. The mood is calm, clean, and wellness-oriented, like a contemporary health and science journal feature. Shallow depth of field keeps the capsules sharp and softly blurs the edges of the frame. The composition leaves generous negative space on the left third for title overlay. The look is a high-end lifestyle photograph with subtle film grain, natural textures, and refined minimalism, with no people, no text, and no futuristic or laboratory elements.

Méně železa každý druhý den: stejný nárůst ferritinu u žen

BY DR. GYMBRO ·

Hepcidin po jednorázové dávce může zpomalit vstřebávání železa, což je pravděpodobná příčina selhání ústních doplňků a jejich dráždění žaludku. V randomizované studii z roku 2026, kde se 66 žen s nedostatkem železa podrobilo léčbě buď 21 mg železa každých 48 hodin, nebo 30 mg denně po dobu 42 dnů, výrazně vzrostl serický ferritin v obou skupinách a rozdíl mezi nimi nebyl statisticky významný. Hladina hemoglobinu zůstala stabilní a gastrointestinální vedlejší účinky byly mírné. Studie však nebyla placebem kontrolovaná a použité formy železa se lišily, takže výsledky spíše srovnávají dva režimy než dokazují nadřazenost jednoho z nich.
