The whole creatine craze reminds me of Vitamin D a couple of years ago. Which also sounded harmless, but can go very wrong if not careful

> but can go very wrong if not careful

This is vague and doesn't explain anything. Can you share any references that communicate what you're thinking about?

They're talking about vitamin D, which accumulates due to being fat soluble and is indeed toxic at a certain level[1]

It became something of a panacea nutrient, recently around COVID.

Your own link shows that what is considered toxic levels are far higher than most people would expect. Vitamin D toxicity is not that easy to accidentally hit.

Overdose has been observed at 1,925 μg/d (77,000 IU per day). Acute overdose requires between 15,000 μg/d (600,000 IU per day) and 42,000 μg/d (1,680,000 IU per day) over several days to months.

And, if you drink a glass of carrot juice a day, you'll receive toxic levels of vitamin A!

~40% of people don't get enough vitamin D [1]. It's not useful to categorize it as some trend, based on people just not following general recommended dosing (with more precise dosing depending entirely on personal sun exposure and skin color).

edit: As an office worker, I take 10k IU per day when I'm entirely indoors (most of the time), but vary it based on sun exposure. I based this on recent studies, and have my doctors approval with an exactly center-of-the-nominal-range vitamin D serum level.

		> severe VDD was defined as serum 25(OH)D levels of <25 nmol/L, moderate deficiency as 25–50 nmol/L, insufficiency as 50–75 nmol/L, and sufficiency as >75 nmol/L. These numbers seem high to me. The 75 nmol/L (30ng/L) is not really a reliable value. It was published in a research that raises many questions due to conflict of interests. Hence the > ~40% of people don't get enough vitamin D becomes: > ~40% of people in the USA don't get enough vitamin D according to Dr. Holick Where I live the norm is 20 ng/L and if we apply that, then the shocking 40% becomes more reasonable 10-15%

My doctor added vitamin D test to his patients recurring blood work since the start of COVID, and found out just about all his patients was deficient or near it.

If you don't have a primarily fish based diet or spend hours under direct overhead sunlight every day without a shirt on, you're probably deficient as well.

		That's a bit of an exaggeration, Vitamin D does not require hours in the sun: > Recommendations to Obtain Adequate Amount of Vitamin D. > Sun exposure to the face, arms, hands, and legs without sunscreen for 5 to 30 minutes at least twice a week or more between the hours of 10 am and 4 pm Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC8299926/ Now that's for most people: if you live in Alaska then during the winter maybe you need a litle more or something ... but the point is most people just need a little sun, < 30 minutes twice a week.

I've also heard about it 'hardening' in the bloodstream and that you should really be taking it with K2 as well. This is anecdotal so someone please do more research than basing anything from this comment

Unless you have specific issues, creatine is pretty easily excreted in excess, unlike fat-soluble vitamin D.

This doesn't mean you can just pound it, but for the most part it just becomes waste product.

Craze? People have been taking creatine for decades. It's really well studied and is quite safe.

		I saw someone handing out samples of creatine at Costco the other day, spouting all sorts of stuff like it's a wonder drug. It's definitely becoming mainstream. I've taken it off and on for the past 15 years, the most noticeable effect is about 5lbs of weight gain. I do think it helps gym performance and the increased water retention mames for better muscle definition.

You definitely want to take breaks from Creatine. It’s not something people should take year around.

		I understood the idea that you need to cycle creatine to be a myth.

		Citation please? Creatine is one of the most studied modern supplements, and I have yet to see anything that says to you'd need to 'take breaks' from it...
