Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Also: notice the LD50 for vitamin D is 37mg/kg.

Based on https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8709011/, a therapeutic regime for very low vitamin D levels is taking 6k IU per day for 3 months, or 50k IU once a week for 2 months.

1 IU is 0.025 μg, or 0.000025 mg. 50k IU is 1.25 mg.

I buy bottles of 5k IU vitamin D pills. Each bottle has 90 pills. That's 11.25 mg of vitamin D per bottle. I'd need to take well over 200 bottles of these pills to have a 50% chance of dying.

Yes, an objectively small amount of purified vitamin D will kill you. But it's quite safe in practice because the environment only has objectively tiny amounts of the stuff. Even high dose pills contain a tiny amount of the stuff.
