What Vitamins Should You Really Take Each Day To Benefit Your Health?

Making sure your body gets the essential vitamins and minerals it needs is incredibly important for maintaining overall health and living as long as possible. 

Vitamins and nutrients are used for various bodily functions, such as for your metabolism to function properly, to keep your immune system running smoothly and to help your body repair itself when injured. 

While a balanced diet is the best way to meet nutritional requirements, some people may need dietary supplements to fill in the gaps due to dietary restrictions, medical conditions or lifestyle factors. 

Here’s a detailed look at what vitamins should you take every day, along with important minerals, too.

Remember, before starting any supplement, speak with your doctor to make sure it's right for you.

Important Vitamins to Take Daily

Multivitamin

When thinking, ‘What vitamins should I take daily?’ a multivitamin can help.

Think of a daily multivitamin as a nutritional safety net. It’s a great way to make sure you’re getting all your essential nutrients and you can find ones tailored to specific needs, such as age, gender or lifestyle. For example, women may need more iron and older adults may need more vitamin D. 

They are particularly useful for:

  • People with dietary restrictions (vegans, vegetarians) or whose diet lacks variety. 
  • Those with busy lifestyles who may skip meals.
  • Individuals looking to support energy, immunity and bone health.

If you do choose to take one, make sure you follow the supplement directions and be consistent, as regular use helps maintain your body’s optimum nutrient levels. They’re best taken with food to aid absorption and prevent stomach discomfort.

End Note

Learning about what vitamins every day you should be taking can be daunting but it’s important to know that a well-balanced diet is the best way to get essential nutrients, with most people able to get all the required essential vitamins through food. Supplements, however, can help if you have specific deficiencies or dietary restrictions. 

You may also benefit from additional supplements, such as LPC omega-3s, probiotics, curcumin or ones targeting specific health concerns, such as Xandro’s Protocol X, a daily ‘longevity’ multivitamin.

For more about, ‘What vitamins should I be taking?’ make sure to speak with your doctor. Also, have a chat with your doctor before taking supplements to make sure they fit your personal needs and won’t interact with any medications you’re taking.
