Interesting thread over at 4chan.

Recommended doses for D3 way to low to achieve desired concentration of 100nmol/L.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5541280/
Also for dickmaxxing get 50.000 IU of vitamin D3 and 100mcg K2.

Any thoughts on this? Also interesting for testosterone increase, since the widely recommended dose of about 1000 IU is way to low according to the first study.

Directly contradicting the other studies. So it's the build up of calcium that acts toxic when overdosing D3. How to mitigate that?
Magnesium seems to work against calcium build up
I think k2 is some kind of signaling molecule that activates osteocalcin that binds calcium into bones and GLA that removes calcium from soft tissue.
so combine D3 and K2 as suggested in the dick study, and one should be fine?
I have no idea. I didn't even look at that weiny study because those also seem to have "amazing results" regardless of what they're shilling. I've just been lurking in d3 and k2 threads for a long times in hopes I can get reasonable understanding of how important they are and what they can do and what forms work and if d3 injection is more practical ect. I'm still no closer to an answer because of all the misinformation and chemistry illiterate people who like to argue here.
not to mention this "vitamin D" crap is sythetic toxic sludge. I remember taking a bunch like 10 years ago and becoming inflamed. Repeated it a few days later just to be sure, then threw out the bottle and never took that toxic sludge again. Amazing Goatis was right
Don't overdose on D3 you only need a small amount of it. These dick increase memers are trying to kill people with hypercalcemia.
yeah, I'm kind of suHispanicious of the dick study too, but the other study also suggests way higher daily doses of D3, around 10k IU. I read somewhere the recommended dose in USA is about 600 IU/d. That's a big difference.
An adult woman can take 600-800 IUs daily for pretty much the rest of her life (outside pregnancy) with no issues. any toxicity buildup in an active person can be balanced by natural filtration.
Obese people suffer from vitamin d toxicity for obvious reason a lot more.
Men can safely take 1k 800-1k IUs with pretty much no issue for the rest of their life.
D2 can be mega dosage once a week because D2 is a lot more stable in its absorption. You don't get as much as D3, but you also don't need to worry about additional factors such as eating a specific amount of fat that day or worrying about cardio. Which you do with D3.
Which is why D3 is better taken daily as every day factors greatly change its absorption rate.
>The incidence of type 1 diabetes (T1D) has been doubling every 20 years. In Finland, the recommendation for daily vitamin D supplementation was gradually reduced from 4000-5000 IU in 1964 to 400 IU in 1992. Concomitantly, T1D increased by 350% in those aged 1-4 years, 100% in those aged 5-9 years, and 50% in those aged 10-14 years [1]. However, since 2006, T1D has plateaued and decreased after an increase in serum 25-hydroxyvitamin D (25[OH]D) after the authorities’ decision to fortify all dietary milk products with cholecalciferol [2]. Moreover, the worldwide association of ultraviolet (UV)-B light and vitamin D status with T1D and multiple sclerosis is now more than evident.
Seems like around 1k/d is still way to low.
Also what's the upper level before toxicity may occur? Read somewhere 50k other studies suggest above 100-150k. So 10k can't be too bad? Off course I depends where you are located and what amount of sunlight you are getting.
the issue is that the affects of vitamin d toxicity are much greater than having slightly low D levels.
also the answer to upper limits is whatever pushes you past 80 ng/ml in a 6 month period.
Even that is entirely dependent on you, some people could be 60-70 ng/ml.
I have no way of calculating that for you.
Which is why i'm telling you that whoever is posting that bullshit online is lying to you.
Vitamin D is entirely dependent on bloodwork and bloodwork alone.
I measure your vitamin D, I supplement, I adjust when near toxicity is achieved.
50k IU D2 is enough to raise my blood concentration at 195lbs. So anyone saying 100k daily is a fucking retard or a super obese mother fucker.
Really no exception m8. it's a fat soluble vitamin so it really is dependent solely on your body fat.
>the issue is that the affects of vitamin d toxicity are much greater than having slightly low D levels.
Considering the overall effectiveness of having a healthy level of D3 against cov, having a slightly high D3 level seems not so Bad. But also Im retard, so what do I know.
Where did you get the 60-70 nmol/L? The study suggests 100 to be the Optimum. So who can I trust? What is backed by more studies?
Also what's the difference between D3 and D2? I'm having a hard time with these studies and medical Jargon maybe you can explain for a dunbass?
Bro, the negatives of D toxicity are way higher than having slightly low D levels. Namely you just fucking die from a heart attack as calcium. It's an electrolyte and needs to be stable.
There are numerous list of side effects of excess calcium.
80ng/ml is the baseline for which vitamin D should be calculated as it's the safe range of optimal vitamin D intake. Any lower and you are deficient. Any higher and you run the risk of closing into vitamin D toxicity.
This number was chosen as the average of outliers.
As you become more obese or skinnier your needs obviously change. So we want a safe range where we know you are close to optimal. Not above or below.
Hints 80.
>what is backed by more studies
not the people telling you to take 100k daily that's for fucking sure.
Did it state in the study they kept taking them for over a year? did it state how long they took them at all. Did it state what the diet was or the body fat, or literally any of the NUMEROUS factors needed to calculate this shit?
I am telling you as someone who gets blood work done every 2 months and has an extremely stable vitamin D level. With no issues with dick function in any way, nor fatigue, or any other issue associated with low vitamin D.
Stop looking for shortcuts that can seriously hurt you when you're suppose to use supplements as intended. As a supplement.
The fatter you are the more vitamin D you need to maintain optimal levels. The skinnier you are the more you have to have your vitamin D levels checked because you lack the storage capacity for maintaining vitamin D a fat soluble vitamin.
The largest difference between D2 and D3 is absorption mechanism.
D3 is a lot easier to raise your D levels, but it's also very unstable in the absorption process. One day it can raise it as intended, the next depending on what you eat or what you do it can skyrocket your day to day D levels.
Which is why small dosage D3 is the best. taken every day or every other day.
thank you anon. That's very comprehensible, even for me. Glad I started this thread, for this info alone, before I started overdosing on D3.
the best way to do this FYI.
>get initial blood work
>discuss with doctor what optimal levels would be or slightly above optimal levels if you want to be safe.
>calculators online that will tell you how much d to take and for how long
Yeah that's where I see the problem. How do I know my generic Dr knows what the actual concentration should be?
honestly don't know what to tell you m8.
you can calculate your intake yourself, but you still need a baseline checked via your blood results.
if you don't have baseline, you have no way of calculating intake needed to remain in safe range.
Vitamin D2 on the other hand is derived from mushrooms exposed to light.
While it's absorption rate is lower, it is very very easily absorbed at any condition.
Meaning when you take it at mega dosages, you get the same amount no matter what you did that day (generally, always exceptions to everything).
So if I only absorb 50-60% of a 50k I know I will roughly always absorb that amount.
D3 can be as low as 50% and as high as 99% bioavailability. That's a huge variance and therefore mesadosages can cause rapid toxicity.
Is this seriously another vitamin D thread?
Fuck off newfag.
For the record, Vitamin D is deficient, but the larger problem is VitD needs magnesium to metabolize into its active form.
You more than likely aren't utilizing the vitamin D already in your body due to this.
So before mega dosing something that isn't going to actually help you, how about you try increasing magnesium instead.
Also for the record, never mega dosage vitamin d3. Take that every day.
you can mega dosage vitamin d2 zero problems once a week.
yes I'm a newfag. But I'm already lurking 2 years. just wondered what fits thoughts were about the study suggesting 10k UI since I never heard this before and have always gone with about 1k.
Vitamin D and magnesium are dependent on eachother.
When you supplement vitamin D you either
1. take a dosage low enough that you know it can be safely taken forever
2. take a very specific dosage measured against your current vitamin D levels to raise them in a timely manner without going over in a 6 month period.
I megadosage D2 every week (50k), just once.
I also have blood work done every other month.
Once it reaches a stable point I am required to drop off to D2 (5k).
We do this effectively forever.
You can't mega dosage vitamin d in any form forever without blood work. You will have toxic buildup.
vitamin d is not something you are suppose to have chronically high levels of. it's suppose to follow the natural cycles of the seasons. inb4 some gay says that's a meme.
Every animal on the planet is affected by seasonal changes why would humans be different.
We just don't want vitamin D dipping too low either. protip this is often why people had fertility feast before winter came.
You ate all day, getting nice plump and fat soluble vitamins in your body. You fucked. You met winter, which slowly drained you of everything.
>dude just overdose on vitamin D lmao
How long are you gonna keep making these threads?
It's been a whole fucking year.
50k is way too much bro
I took 1.2k IU daily for a month and I still managed to fuck up my calcium level
I'm not taking 50k IU
does vit D help with getting any taller? im 20 and my growth plates have almost certainly fused by the way
