- WalterGR 2mo agoThe shortened title is incorrect: the “/“ should be “+”.

- phoronixrly 2mo agoBefore you start self-medicating -- "participants had a mean age of 67.2±8.9" and this is a study focusing on people with mild cognitive impairment. You should see a physician before attempting to treat your poor sleep with vitamin D or melatonin.
- jimmaswell 2mo ago"Self-medicating" with a standard multivitamin is harmless at worst, and so is additional vitamin D supplementation if it's not in the extreme over a long period of time. It has a nonzero chance of helping, and it's a cheap and easy thing to throw into one's routine.
- phoronixrly 2mo agoSpoken with such confidence! Are you a physician?
- stevenhuang 2mo agoFYI most physicians would find parent's advice agreeable. My physician said as much. It doesn't take much reading about a topic as contentious as vitamin d supplements to come to similar conclusions. Have you done any review at all of the relevant literature?
- phoronixrly 2mo agoI have read every article that has hit HN's front page. It seems like at least one per month since I joined in the heat of COVID at which point in time HN was adamant that bolus doses of vitamin d prevented COVID... Each and every article leads to the same conclusion for me though - people should really be asking an endocrinologist instead of Dunning–Kruger-ing their health.
- jimmaswell 2mo agoLet me get this straight: the source of your expertise on multivitamins and vitamin D is HackerNews articles, which makes you more qualified than the average physician, and you're accusing others of Dunning-Kruger?
- OutOfHere 2mo agoAs per the research, what vitamin D did, if an optimal level, is prevent mortality from Covid, not prevent one from getting Covid. I don't recall any basis for claims that it prevented Covid. Doctors are utterly useless when it comes to vitamin D. They don't even test anyone who doesn't beg for it. They also never help optimize anyone's level.
- rfgplk 2mo ago> Are you a physician? This sentence spoken on an engineering forum is pure... idiocy. Physicians are nothing more than bio-engineers, and if you apply sufficient reasoning you'll see that there is very little functional difference between the human body and a computer program (monadic equivalence)

- OutOfHere 2mo agoNo one treats their sleep with vitamin D. It's not what people take vitamin D for.
- Aurornis 2mo agoStudy was in an elderly cohort with cognitive impairment. This is a cohort more likely to have nutrition and diet problems and spend all of their time indoors. I haven’t found the full study but the results look marginal for a narrow group. Then there’s this important note in the highlights: > Higher daily Vitamin D intake may impact cognition in persons with sleep disturbance and MCI. More is not better with Vitamin D. Correcting deficiencies is good but the mega dosing trend is not.
- phoronixrly 2mo agoI'd like to add that correcting deficiencies implies seeing a physician to get your dosage right. This is necessary both for Vitamin D and Melatonin. If you're not a sedentary geriatric with MCI this study is probably not for you.
- zulux 2mo agoSadly, many people in northern areas who are otherwise healthy are vitamin D deficient. It can be a side effect of trying to protect from skin cancer.
- phoronixrly 2mo agoI am not arguing against that. I argue that correcting this deficiency is not in the competence of people who are not medical professionals no matter how many articles they've read on the front page of HN about vit. D.
- zulux 2mo agoYou can very much overdose on Vit D. I suspect your risk tolerance is different than mine.
- phoronixrly 2mo agoYou can very much overdose with melatonin as well, leading to your sleep schedule getting worse and worse the larger the dose. Ask me how I know before assuming my risk tolerance.
- OutOfHere 2mo agoAll those professionals (scientists, doctors, etc.) who for decades told you not to supplement a good dose of vitamin D have been trying to get you killed. Often they work for big pharma or industry interests, and want to peddle million dollar medicines that don't even work right. They would have us live and die in ignorance. It's also no surprise that healthcare expenses are through the roof. Supplemental vitamin D is hurting the business of endocrinologists most of all.
- rfgplk 2mo agoToo extreme of a take. They're ignorant at best. In fact after cholecalciferol/calcitriol and the whole vitamin D receptor family, ignorance of the importance of bacterial balance and mineral intake are the next two biggest categories.
- OutOfHere 2mo agoIt is an accurate take wrt the scientists who publish articles with misinformation about vitamin D, also with regard to the government which continues to formalize a grossly incorrect requirement. The medical profession has formally defined a daily requirement of vitamin D as 600 IU per day of D3 which is a killer low dose. It is as if the vitamin C requirement were to be defined as just 11 mg per day, which would be comparably deadly.
- AlawamiAZ 2mo agoNot an interventional RCT. This belongs to the useless pile of Vit D observational studies.
- dlcarrier 2mo agoCheck out interventional RCTs for near-infrared light exposure. They're showing a lot more promise than for ultraviolet light exposure or vitamin D supplementation.
- sublinear 2mo agoWhy does every health topic on HN attract so much comment spam? This was posted 2 hours ago, and right now it's the fearmongerers and pedants. I'm expecting the next wave of comments to be the promoters of bad supplement advice and personal blogs. I'm surprised nobody has mentioned peptides or whatever else yet. That's when you know the discussion has really gone to shit. Nobody wants to honestly discuss vitamin deficiencies and their impact on quality of life? Most people do have deficiencies. Many of them have otherwise unexplained minor symptoms that are proven to be related to mental health. Vitamin D is at the top of the list. It's worth getting checked out in your routine bloodwork during a doctor visit. The recommended amounts are what is optimal, but what is strictly necessary is usually far lower. That's why people aren't keeling over and why most of them don't care. Most people have suboptimal diets for a million tangential reasons not worth arguing about. Intake may not even be the problem if you have an undiagnosed endocrine or metabolic issue. Lots of people are prediabetic, drink too much, etc. I don't think this short list of facts will help, but can we get back on track?
