Guide des complements alimentaires pour sportifs : vitamine B

Card grid infographic titled "Vitamin B Complex". 8 uniform cards in a clean grid, each with a clear central icon/diagram, a name in English with canonical form where applicable, one-line description in English. Cards: Vitamin B1 (Thiamine) — energy metabolism and nerve function; Vitamin B2 (Riboflavin) — cellular energy production and antioxidant support; Vitamin B3 (Niacin) — energy release and skin and nervous system support; Vitamin B5 (Pantothenic Acid) — coenzyme A production and hormone synthesis; Vitamin B6 (Pyridoxine) — amino acid metabolism and neurotransmitter synthesis; Vitamin B7 (Biotin) — macronutrient metabolism and hair, skin, and nail support; Vitamin B9 (Folate) — DNA synthesis and cell division; Vitamin B12 (Cobalamin) — red blood cell formation and neurological function. Include a separate clean callout panel within the grid: "Consult Your Doctor" with a simple medical icon and brief general caution text in English. Add small neutral visual indicators for general food sources and athlete-support context, but no dosage recommendations beyond broad general ranges, no brand packaging, no product boxes. Minimal flat editorial reference-poster illustration, minimal monochrome palette, clean spacing, simple geometric icons, consistent card layout, subtle comparison symbols and nutrient-related diagrams. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no real brand logos, no watermarks No specific brand boxes. No dosage recommendations beyond general ranges. Clear "consult your doctor" callout.
