Taking vitamin supplements is one of the easiest ways to make sure that you meet all your nutrient needs, but one thing that is often overlooked is the time these supplements are taken. When people choose to take their daily doses of vitamin supplements it is usually governed by convenience more than anything else, but the timing of when you take the vitamins can be as vital as the fact you take them.

Vitamin Types And What Time To Take Them

There are 2 types of vitamins, fat soluble and water soluble. Your body needs a total of thirteen vitamins to function which include vitamin A, vitamin B6, vitamin B12, vitamin C, vitamin D, vitamin E, vitamin K, niacin, riboflavin, biotin, folate, thiamine and panthothenate.


Water Soluble Vitamins:

  • Biotin (vitamin B7)
  • Folic acid (folate, vitamin B9)
  • Niacin (vitamin B3)
  • Panthothenate (vitamin B5)
  • Riboflavin (vitamin B2)
  • Thiamine (vitamin B1)
  • Vitamin B6
  • Vitamin B12
  • Vitamin C

Nutritionists urge people to take all the B vitamins together because when taken together they have a complex interaction making them far more effective, but trying to obtain every single B vitamin from your foods can be very difficult so taking a Vitamin B Complex supplement can greatly benefit you.

These kind of vitamins are not stored in your body so you will need to consume them more often, it helps release energy from food, produce energy, make collagen and build protein/cells. All water soluble vitamins should be taken first thing in the morning with breakfast for maximum effectiveness.

Fat Soluble Vitamins:

Your body stores these vitamins in your liver and fat for future use to help build your bones, protect your vision/body and allow the absorption/storage of vitamin A. Vitamin E is best taken in the morning with dietary fats like whole milk, whole eggs, nuts, yogurt, avocado etc. Vitamin A, D and K should be taken in the afternoon once again with dietary fats for maximum effectiveness.

Do We Need Actually Need To Take Vitamin Supplements ?

Taking vitamin supplements has been a controversial issue since many recent studies have shown that it may be unnecessary and actually do more harm than good. For example a study published in 2008 showed that folic acid which is contained in most multivitamins can increase the chances of prostate cancer. Another study that tracked the mental functioning and multivitamin use of 5,947 men for 12 years found that multivitamins did not reduce risk for mental declines such as memory loss or slowed-down thinking.

Multivitamins will most often times take you over the top of the recommended dose of a certain vitamin and that is where the problem lies since overdosing on supplements in some cases may be life threatening.

To sum up not all vitamin supplements are bad just multivitamins since they provide you with 100% of each vitamin and overdosing is just inevitable. The best way to solve that problem is of course either eat more whole foods so that you don’t have to take any vitamin supplements or get each vitamin supplement separately (really only the vitamin b complex and fish oils are worth getting) and take them at the correct times.

  1. This is very interesting. I for one am guilty of having all my vitamins at the same time.

    Thanks for informing us that Vitamin A, D and K should be taken in the afternoon. That’s good to know.

    In your opinion, should one have a blood test to check what vitamins they are lacking. I know its not a common practice, but just to prevent overdosing. What do you reckon ?



  2. Hi Andrew,

    Great article, I really liked the read !

    I was taking multivitamins once and I had an overdose of vitamins in my body. I couldn’t sleep anymore and I had so many headaches. So, I went to the Doctor and after a check up he told me that I took vitamins my body didn’t need to. The only vitamin I really needed to take was vitamin D. What I didn’t know is that it is more efficient when taking it with dietary fats. Great to know and thank you for this useful info 🙂

    I look forward to reading more of your interesting articles !

    1. It really is the best to just individually take vitamin supplements instead of one multivitamin just like how you only needed extra vitamin D and nothing else. It may be more expensive, but when your health and well being is on the line the price probably won’t matter.

      Glad you enjoyed the read Daniella 🙂

  3. Hi Andrew,

    Great post. I had no idea folic acid was associated with prostate cancer. I used to take it years ago and 5 years ago I was diagnosed with prostate cancer. I was lucky and was able to heal it myself with whole foods and fasting, but I had no idea about the folic acid. Interesting.

    I don’t take too many supplements as I eat a lot of vegetables and fruit, but yes some are full of filler so I will need to research properly if I do choose to take any.

    Cheers, Kev

    1. Wow it really is amazing what healthy living and eating can do Kevin ! and definitely too much folic acid was probably one of the main causes of your prostate cancer, but now it’s gone 🙂

  4. Interesting post on vitamins.

    I never really thought about the best time to take my multi vitamin. I just usually pop it in my mouth before leaving for work in the morning. As you said its a convenience factor for me so that I don’t forget about.

    Your article also brings up a valid point about multi vitamins not being good to take.

    Do you suggest I buy the individual vitamins and tailor the doses closer to the recommended intake ?

    1. Yes its best to buy individual vitamins and tailor it to what kind of vitamins you are missing each day, but really the best way is just to get fish oils and a vitamin b complex to keep it simple or else you’ll be carrying so many pills it may become a burden.
