How beneficial are multivitamins?

The global market for vitamins and dietary supplements was estimated at $177 billion in 2023, with the U.S. market accounting for at least $45 billion of that, according to Grand View Research. This figure is expected to grow significantly in the coming years due to increasing awareness of the importance of nutrition and an aging population. In the US alone, consumers spend approximately $60 billion annually on nutritional supplements, according to UCHealth

So, it is fitting to ask, just how beneficial are multivitamins?

For healthy adults, there's generally not much evidence that multivitamins offer significant benefits in terms of preventing diseases like cancer or heart disease, or improving overall mortality. While they can be helpful in filling nutrient gaps for some individuals with specific dietary needs or deficiencies, a balanced diet is typically sufficient for most people to obtain the necessary vitamins and minerals, according to Piedmont Healthcare and Harvard Medical School. 

Here's a more detailed breakdown:

• No significant impact on mortality:

  
  

  A large study following over 390,000 healthy adults for 20 years found no association between multivitamin use and a lower risk of death. 

  
  

• Limited impact on chronic diseases:

  
  

  Many studies suggest that multivitamins don't significantly reduce the risk of heart disease or cancer. 

  
  

• Potential benefits for specific groups:

  
  

  Multivitamins may be beneficial for individuals with certain dietary restrictions, like vegans or vegetarians, or those with specific health conditions that affect nutrient absorption. 

  
  
  
  

• Food is the best source:

  
  

  Micronutrients are best obtained from whole foods, as they also contain other beneficial components like fiber and antioxidants. 

  
  
  
  

• Consider individual needs:

  
  

  If you're concerned about nutrient deficiencies, consult with a healthcare professional to determine if a multivitamin or specific supplements are right for you. 

  
  

• Potential risks:

  
  

  While generally safe, excessive intake of certain vitamins and minerals can be harmful. 

  
  
  
  

Summary

The quick profit incentive and a gullible and willing aging public result in an irresistible business opportunity for venture capitalists.

Markup on Supplements: The markup on supplements can be substantial, often ranging from 40% to 100% or more, depending on the type of supplement and the brand. 

In conclusion, while multivitamins can be a useful tool for some individuals, they are not a substitute for a balanced diet and may not offer significant health benefits for the general population. 

Questionable benefits coupled with windfall profits make buying supplements a dicey proposition.

Get a blood test to ascertain your specific deficiencies and let a medical doctor tell you what you need.

Otherwise, it is your prerogative to keep your precious money in your pocket.
