Wie lange dauert es einen Vitamin B12-Mangel zu beheben – Dauer und Faktoren

I notice that the raw article content from Prompt 2 was not included in your input. The article source is empty, and the external/internal link arrays are also empty.

To render the HTML article according to your specifications, I would need:

1. **The complete article content** from Prompt 2 (the structured article text)
2. **External citations** (at least 6 URLs to link)
3. **Internal link suggestions** (URLs from your domain to interlink)

Could you please provide the article content and link data? Once received, I will immediately render the publication-ready HTML article following all your formatting rules.
