Wellness Wednesday for February 14, 2024

The Wednesday Wellness threads are meant to encourage users to ask for and provide advice and motivation to improve their lives. It isn't intended as a 'containment thread' and any content which could go here could instead be posted in its own thread. You could post:

  • Requests for advice and / or encouragement. On basically any topic and for any scale of problem.

  • Updates to let us know how you are doing. This provides valuable feedback on past advice / encouragement and will hopefully make people feel a little more motivated to follow through. If you want to be reminded to post your update, see the post titled 'update reminders', below.

  • Advice. This can be in response to a request for advice or just something that you think could be generally useful for many people here.

  • Encouragement. Probably best directed at specific users, but if you feel like just encouraging people in general I don't think anyone is going to object. I don't think I really need to say this, but just to be clear; encouragement should have a generally positive tone and not shame people (if people feel that shame might be an effective tool for motivating people, please discuss this so we can form a group consensus on how to use it rather than just trying it).

What is the recommended dose of vitamin D supplements? I've seen cited doses between 50 and 600 IU but I've read that this are actually severely underestimated.

As for buying supplements, can I just buy some random brand on amazon?

I would also like to know the answer to this. I just started taking 5000 IU personally. Since many people take 10,000 IU for years without issues that seems to be a safe amount. A white person would get at least that much (and possibly much more) from a pre-modern amount of sun exposure.

High levels of Vitamin D in the blood are correlated with all sorts of positive health outcomes, but so far data on the value of supplementation has been mixed. It's quite possible that these studies are using too-low levels of supplementation. 400 IU?! What is that - a supplement for ants?!

Another possibility is that sunlight might produce a higher level of bioavailable Vitamin D or that sunlight has other unknown benefits which are correlated with Vitamin D but not caused by Vitamin D. For that reason, I deliberately tan during the summer months, taking care not to burn or to get sun on my face and neck.
