Apple Health Nutrition Logging means Unfair can save eligible nutrition-related supplement records to Apple Health when you allow it.
How it works
When you log a supplement in Unfair, Apple Health receives eligible nutrition-style supplement records when permissions are turned on.

If records do not appear
Check Apple Health permissions for Unfair and make sure the needed permissions are enabled.
Also allow a short delay for syncing.
Your fallback
Even if syncing fails, your Unfair log still keeps your timeline in the app.
