Someone needed to tell her she was wrong, and she wasn't going to listen to her daughter.

No matter how much school you've attended and how many years you've practiced as a doctor, there will always be some mom with an internet connection who thinks she knows better about medicine than you. It's not a mortal sin to use the internet to look up your symptoms and try to figure them out before seeking medical treatment, but you cannot treat a random article or an AI-generated search result as the gospel truth. It fails to consider all the factors at play, and the internet cannot prescribe you treatment the way a doctor can.

People who follow a crunchy lifestyle do so because they prefer not to rely on doctors, or they've had negative experiences with medical professionals in the past and want to make their own decisions about their health. This community often claims to've researched to support their medical choices, but that research usually doesn't extend beyond social media, where uninformed individuals affirm each other's unconventional approaches to self-care. It's no wonder the mom in this story thinks that she's right, and her daughter and her doctor are wrong.

  • The teenager in this story is smart enough to know that she probably shouldn't be taking 700 milligrams of magnesium every day, but her mother is not. Her mom relies upon unreliable medical information from the internet, and was outright furious when her daughter's doctor proved her wrong.

  • Am I wrong for embarrassing my mom in front of the doctor?

    So I (16f) and my mom (51f) went to my neurologist appointment yesterday because my migraines have been acting up like crazy lately. My mom is really into

  • The thing is I'm not doing that out of disrespect, I do my own. research and some of the stuff she has me taking either won't do anything for my migraines, or is to much. Like she has me taking almost 700 milligrams of magnesium a day that's insane. I

  • brought it up to her after doing my own teacher and finding that I really shouldn't be having more than 400 milligrams a day and she got pissed at me. She also gets mad when I refuse to read the chat gpt "articles" she sends me but I dont think it's all the accurate. (Especially cause it suggested I take 850 milligrams somehow)
    via u/OliveComprehensive75
  • So when she was taking about all the prescriptions and medicines with my neurologist my mom mentioned one of the pills she has me taking. The doctor suggested I stop taking it when my new prescription comes in because it also has magnesium in it. I decide to ask how much

  • I don't think I'm really the butthole because I had been telling her but she dosent wanna listen to anything that ain't chat gpt or anyone younger than her. It's about my health and I was just trying to show her that I know what's good for me as well.

  • Additional_Initial_7 NTA, and honestly she probably wasn't embarrassed enough. Your mom is going to end up damaging your organs. Vitamins and supplements absolutely can be toxic in the wrong dosages. Stop taking health advice from your deranged mother and only listen to medical professionals.

  • Few-Dare-540 Totally get that, it's scary when parents push stuff that could actually be harmful, you just have to look out for yourself.

  • CryptidCricket When I've seen doctors bring it up, they'll generally tell you not to take anything you don't need. Unless your bloods show a deficiency of some sort or a professional recommends trying something, it's probably better to avoid them.

  • The laws around supplements are pretty questionable in places, too. They don't technically fall under food or drugs, and so aren't always subject to the same safety testing as stuff in those categories.

  • Sugar_Kowalczyk OP: Disclose to your doctors EVERYTHING your mom has you take. Some supplements can fuck with medications and make them less effective. Honestly, this feels borderline Munchausen-by- proxy to me. She could hurt you doing what she's doing. It's irresponsible at best, very dangerous at worst. Her reactions to you are childish and make me concerned about her judgement. Keep being personally responsible like you have been and find a trusted adult to talk to about this and help you re

  • LovemeSomeMedia Yeah. People have this stupid misconception that "natural" good or safe, but just like anything you put in your body, you can o ose on supplements and vitamins. Some of them even contraindicate themselves. For example you shouldn't take Calcium and Iron together because Calcium stunts iron absorption. Same with Magnesium and Calcium. You have to be just as careful taking natural remedies as you would actual prescription med, arguably more given how supplements aren't as heavily r

  • Broad_Application_55 NTA... I'm an RN, we NEED to know everything you're taking, including supplements, because dangerous interactions can occur. And magnesium is one up need to be careful with. I also take it for migraines, but too much can really affect the heart. Please be honest with your doctor, it could literally save your life.

  • wibbly-wobbly-worm I don't understand why people are trying to make you the asshole. You're the asshole for making a playful jab at her for... slowly poisoning you with pseudoscience? Who cares if she's 'just trying to help' when her method of doing so is fucking around with unregulated supplements. Let me be clear; 'supplement' is an unregulated term. Anybody can put virtually anything in a 'supplement' and sell it as a wonder cure and there's no law stopping them. And she is regularly finding

  • Cutmybangstooshort ⚫ 13h ago I would call that a playful jab personally. She's growing up. If you're lucky, you reach a time when you're friends with your Mom, always respectfully, of course. My parents were pretty strict but that wouldn't have been considered bad. Her mom got embarrassed and can't handle it. Mom has more invested in her supplement life than their relationship.

  • natangellovesbooks NTA. I would have asked her to leave so you can discuss medical stuff with your doctor as "practice " for being an adult. I step out of the room for my 16 year old daughter in case she wants to talk with the doctor about something she isn't willing to share with me. Then brought it up then.

  • Idk if you can bring that up at a next appointment. In front of Doctor, say, "Hey mom, I want to practice talking with the doctor when you aren't here because I'll be 18 soon and they won't let you in with me then.” Hopefully your doctor or nurse recognizes what is going on.

  • I mean I as a parent of a 16 year old, I would ask the doctor if the "oral supplements" I am giving my child are safe. There are so many possible interactions that can happen. By the way, I am proud of you for self- advocating. It takes a lot to defend yourself from your parents. I never was able to.
    via u/natangellovesbooks
  • px13 Normally I'd agree, but I think this mom needs to hear it from the doctor. She clearly won't believe what her daughter has to say.
    via u/px13
  • TheNightTerror 1987 I hate to say it, but a mother like that might well not believe even the doctor and claim they don't know what they're talking about because they haven't read the most up to date research yet or some such bullshit.
    via u/TheNightTerror1987
  • One_and_only4 NTA. Good for you for defending your position that you were right. It isn't like you haven't done research and it shows your mom can be wrong.
