It's easy to get sucked into the marketing scheme of vitamins today. With all the new companies popping up offering "personalized miracle" vitamins, it's hard not to buy in.
I have always heard: "You can get everything you need from a good diet." But I have to admit, I was starting to doubt that thanks to all the new vitamin ads I have seen over the last couple years.
Well, turns out, that statement is just as true today as it was years ago when I first heard it. In fact, science over the last years has built an even stronger case against supplementing------
***********Disclaimer! I am not a doctor. This post is based off information for a healthy adult with NO deficiencies or health conditions. If you have a deficiency or health condition, please consult your doctor.**************
Several studies have been done to test the effectiveness of multivitamins. All studies revealed multivitamins do not reduce the risk of mental declines, cancer, heart disease, heart attacks, heart surgeries or heart-related deaths.
Things to remember:
Pills are not a shortcut to better health and prevention of diseases.
If you follow a healthy diet, you can get all the vitamins and minerals you need from food.
The benefits of a healthy diet and maintaining a healthy weight far outweigh what any supplement can do.
Think of vitamins as a bonus boost --- don't rely on them to do the job. Our body was designed to get our nutrients from our diet, not a pill.
With all that being said, there can be some gaps your diet can't fill...at least all the way and/or all the time. Experts do recommend minor supplementation of some vitamins (remember bonus boost!).
So I compiled a list of 9 vitamins that are most likely to be low. I need to clarify: I didn't say deficient...true deficiencies are uncommon. Low levels however, is much more common.
All, except one, are essential nutrients, so it really doesn't hurt to supplement these. Especially since stress is a huge factor in depleting our levels and who isn't stressed now-a-days??
I provided foods that are high in the vitamin, so you can choose to up your intake on those foods or supplement. It's your choice! But, if you do decide to supplement, please be mindful of the DV amount. There is no reason to get over 100% or even close to 100% of your DV. In some vitamins, excess can actually cause issues (GI is most common). Try to find the lowest amount.
TOP 9
GLOSSARY
Essential nutrient: A nutrient we must get from food or supplements because our body cannot produce or store it.
Bioavailability: Refers to the extent a substance or drug becomes completely available to its intended biological destination. In other words, a more efficient absorption.

SUPPLEMENT RECOMMENDATIONS
Long story short: children's vitamins are your best bet.
Let me reiterate the goal of this post: to encourage getting vitamins from your diet first and using supplements as a bonus. Adult vitamins simply have too many and too high of doses for those trying to get all or most of their vitamins from their diet. It's just unnecessary.
Kid's vitamins have fewer, healthier ingredients, are sugar-conscious, and lower in dose. Oh and also super fun flavors. Win!
