Discussion Overview

The discussion revolves around the safe dosage of vitamins, particularly concerns about potential side effects and the risk of hypervitaminosis. Participants explore the implications of taking high doses of various vitamins, including fat-soluble and water-soluble types, and the timing of subsequent doses.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants question how much of a vitamin can be taken before side effects occur, suggesting extreme doses like 20 or 100 times the normal amount.
  • There is a query about whether acute hypervitaminosis can occur immediately or if it develops over time.
  • One participant mentions the possibility of needing to wait a certain number of days after taking a high dosage before taking another high dose.
  • Another participant suggests looking up the LD50 for vitamins, indicating that side effects may occur before reaching that level.
  • A participant shares a personal experience with a multivitamin supplement that they enjoy, prompting a question about its relevance to the original inquiry.
  • Information is provided about fat-soluble vitamins being retained longer in the body, which may lead to unrecognized overdosing, while also noting that some B-complex vitamins can cause overdose.
  • There is a caution against taking more than the recommended dietary allowance (RDA) of vitamins without medical guidance, emphasizing the importance of consulting a physician.

Areas of Agreement / Disagreement

Participants express differing views on the safety and implications of high vitamin dosages, with no consensus reached on the specific risks or guidelines for intake.

Contextual Notes

Limitations include the lack of specific dosage recommendations and the variability in individual responses to vitamin intake, as well as the absence of consensus on the timing of subsequent high dosages.

Who May Find This Useful

This discussion may be of interest to individuals considering vitamin supplementation, those curious about the effects of high dosages, and anyone seeking to understand the risks associated with vitamin intake.

Before side effects kick in. 20 times the normal dose ? 100 times ? Is there such a thing as acute hypervitaminosis or will it develop in the following days ? If I take a 10 times normal dose, must I wait 10+10 days or more before taking a new high dosage ?

Why do you ask? You can probably look up the LD50 dose of each (if there even is one), but that's higher than when you start to have side effects.

What does that have to do with the question you asked in your OP?
 
This article is an intro to hypervitaminosis:

http://en.wikipedia.org/wiki/Hypervitaminosis

The fat-soluble vitamins, A, D, E, and K are retained by the body longer than the water-soluble vitamins, so overdosing on these can be done without realizing it. Still, it is possible to overdose on some of the B-complex vitamins. You should discuss this with your physician.

Just like you shouldn't take too many antacid tablets (because they taste good), don't abuse vitamins, either. With all the different varieties of candy bars around, you should be able to find a non-therapeutic version to abuse instead.
 
Do not take more than the RDA of vitamins unless directed to do so by an accredited doctor. We do not give out medical advice here. See a doctor if you think you have medical issues that need treatment.
