      Health Nerd Retweeted JAMA

      Given that something like 90% of these supplements are totally ineffective, we should have been questioning this for a long time!https://twitter.com/JAMA_current/status/1034183628077629440 …

      Given that spending on supplements now approaches 10% of our overall spending on pharmaceuticals, it may be time to question their regulation or lack thereof. Read more via @aaronecarroll @JAMAForum http://qoo.ly/rm2m9  #blog

      People get mad at me when I say totally ineffective, so I'll explain: They are totally ineffective ~for the purposes that they are sold~

          Most countries have some sort of regulation governing what exactly supplement manufacturers are allowed to say, but that doesn't really stop them from making claims

          For example things like "may prevent [x]" or "can help improve [x]" These are simply nonsense claims made to dodge regulation

          I do a thread on this every once in a while Supplements make vague claims for health benefits, but these are usually based on either "ancient knowledge" (i.e. nothing), or cherry-picked researchhttps://twitter.com/GidMK/status/1023031022290489344 …

          Milk thistle is a great example: some biological plausibility there, some success in rodent models, but the human trials found no benefit

          Also, it was tested for acute liver toxicity, which means that it hasn't even been tested for "liver health" or one of the thousands of other applications it's marketed for

          The issue repeats itself when you look at other supplements Lavender = mostly useless Garlic = similar Valerian = more of the same And on, and on, and on

          There is the rare supplement that actually works, but the funny thing is that when a product is discovered that has an actual benefit, we isolate the active ingredient and turn it into a drug because that's FAR safer

          The classic example is aspirin: if you want aspirin you can either boil up a batch of willow bark and choke down the tea, along with a bunch of contaminants such as cyanide, or take a small pill with no cyanidepic.twitter.com/zBsE0le3m4

          It's also worth remembering that many supplements are either misleadingly labeled - they don't contain what they say they do - or contaminated with adulterants https://theconversation.com/safety-of-contaminated-vitamins-and-nutritional-supplements-cant-be-left-to-consumers-39901 …

          Worth noting: THIS IS NOT TRUE IF THEY ARE PRESCRIBED BY AN ACTUAL, CERTIFIED MEDICAL DOCTOR If your GP (who is not a chiropractor) tells you to get a supplement, there is probably a good reason
