All these articles about different individual nutrients start to feel like heath whack-a-mole. How about this: to be in the best possible position to beat any serious infection, you need to be in generally good health. That means having adequate levels of all essential nutrients - i.e., all the vitamins, minerals, amino acids, enzymes etc that you get from maintaining a good diet and healthy lifestyle over the long t…

And, try to get those things from foods. It can't be said enough: Fruits and Vegetables have extremely high densities of all your minerals and vitamins. I've calculated all their densities here based on USDA nutritional info: https://kale.world/c All the results are normalized to 200 calories for easy comparison. When you get your vitamins/minerals from a pill, you run the risk of your body not absorbing it because t…

I really dislike using calories when comparing veggies and fruits as it feels like the complete etogn format. Why not use grams?

FYI also, researchers are suggesting that the Lancet HCQ study everyone (and the WHO) references nowadays is fake: https://www.theguardian.com/world/2020/may/29/covid-19-surgi.... The authors could not have had the data they claimed they had. This is just one bit of news you will never find on CNN.

Did my masters on Vitamin D - It is very difficult to extract CLINICALLY RELEVANT information from retrospective epidemiological studies. However, there a a few things that are clear: 1. Calcium absorption from the intestine increases with vitamin D supplementation dose up to around 8-10,000 IU D3 daily. 2. 15 minutes of full body exposure in noon sun is equivalent to a dose of ~20,000 IU D3 3. There are few cases of…

>this excludes people with kidney disorders. Can increased calcium absorption lead to kidney disorders? This is my biggest worry when taking Vitamin D3 supplements, I have Vitamin D deficiency but when I take supplements it quickly reaches to toxicity levels (> 80 ng/mL) and so I have the revert to monthly supplement of 60,000 IU of Cholecalciferol. PSA: I'm a dwarf, possibly Achondroplasia, but during childhood (4 -…

IANAD, but the word is you should couple it with vitamin K to offset the extra calcium absorption. Which is a good idea on general principles, since K is one of the other very few supplements worth taking by the gen pop.

Re #2: the figure gets thrown around a lot. But who is outside, naked, at noon for fifteen minutes? It's really hard to translate that to anything meaningful or actionable. Here's a tool that can help calculate useful exposure depending on your location/time of year. Doesn't take clothing into account however.. https://fastrt.nilu.no/VitD-ez_quartMEDandMED_v2.html

Skin shade, location, time of year, and atmospheric conditions are other huge variables. My pale skin in the midday desert sun for fifteen minutes in July? I'd have a pretty serious burn.

Your skin may be burned but you wouldn’t likely have a vitamin D overdose.

The point is that being outside naked at noon every day for 15 minutes wouldn't hurt you. Therefore, a daily dose of 20,000 IU / day won't hurt you. Therefore, a 5000 IU supplement every day won't hurt you either.

One does not follow the other. Maybe taking 5000 IU orally has a vastly different effect to letting it acculumate through skin? That's purely speculation on my part though, just trying to illustrate that these two are not necessarily equivalent.

For someone who claims to have done a masters on Vitamin D, I find this generalized statement disturbing. What skin tone the person has, what season it is, what latitude the person lives at, age of the person etc., are factors in how much Vitamin D is produced by the body on exposure to sunlight. I’m afraid I can’t take the other points seriously because of the brevity and lack of nuance.

Will your body make vitamin d from sunlight if you already have a enough from a supplement? I’m worried about overdosing if I take 5000 UI and get a lot of sun.

No, it won’t, but that’s only after a certain limit that’s much higher than 5000IU. Even if you spend all day in the sun, your body will stop the synthesis at a certain level (10000IU in the day is what I had read long ago, but that may be incorrect or outdated).

In other words, 5000IU is much lower than what the body would naturally produce when exposed to sunlight for long durations in a day (assuming good latitude, sunny season, lower atmospheric pollution, around noon, lighter skin tone, etc.).

>...And you don't need Vitamin K supplements. Greens are extraordinarily high in Vitamin K. Even, just 20 calories of Spinach will provide over 400% of your daily Vitamin K intake!

I agree with you that most people don't eat enough fruits and vegetables. Though if someone is worried about a particular nutrient, it isn't that simple. It doesn't matter how much Vitamin K is in spinach if you don't absorb it:

>...Circulating phylloquinone levels after spinach with and without butter were substantially lower (7.5- and 24.3-fold respectively) than those after taking the pharmaceutical concentrate. Moreover, the absorption of phylloquinone from the vegetables was 1.5 times slower than from Konakion.
