Someone asked a question along the lines of &amp;#x27;what is something you wish you were told earlier&amp;#x27; and at least one person mentioned Vitamin D deficiency.&lt;p&gt;They said that for most of their life they were deficient and that it had a significant impact on their life-long depression, and their stress and focus if I recall correctly. Once they began taking Vitamin D supplements it drastically changed everything and completely changed their mood: it turned out that they had Vitamin D absorption issues and never picked up on it. They said they take 12,000 IU&amp;#x2F;day, now, and it has changed their life.&lt;p&gt;Most Vitamin D supplements seem to come (in Australia at least) at anywhere from 300 IU to 1000 IU. I looked into safe Vitamin D levels and it appears that you can take up to 50,000 IU a day before you start seeing adverse affects, and just being in direct sunlight for an hour or so is about 15,000 IU for my skin type.&lt;p&gt;With this in mind, I&amp;#x27;ve began taking 7,000 IU a day (I get about an hour of direct sunlight a day at least on most days). I can&amp;#x27;t say for sure that it has an effect on my mood, but on the days where I feel a bit worse than usual it&amp;#x27;s usually because I haven&amp;#x27;t taken my supplement stack for a couple of days (i.e ran out and hadn&amp;#x27;t yet bought supplies).</text><parent_chain></parent_chain></comment><story><title>Consumption of ‘Longevity’ Vitamins Could Prolong Healthy Aging, Scientist Says</title><url>https://www.ucsf.edu/news/2018/10/412016/perspective-adequate-consumption-longevity-vitamins-could-prolong-healthy-aging</url></story>

The text reads, intentionally or not, as if some pill containing everything, all at once, would be the route to longevity.&lt;p&gt;A closer reading says roughly.. that some crucial nutrients are not on an ordinary &amp;quot;daily requirements&amp;quot; list because their effects have not been sufficiently observed over long time scales, and conversely that the contents of an ordinary &amp;quot;daily requirements&amp;quot; list are there because their absence makes a person ill relatively quickly. The note at the end says that the medical author has more than four decades of research experience, and is well-respected.</text><parent_chain></parent_chain></comment><story><title>Consumption of ‘Longevity’ Vitamins Could Prolong Healthy Aging, Scientist Says</title><url>https://www.ucsf.edu/news/2018/10/412016/perspective-adequate-consumption-longevity-vitamins-could-prolong-healthy-aging</url></story>
