Get the most out of your supplements

Find out when to take them, how to combine them, and what to avoid.

PlanYourVitamins.comDid you know that nattokinase should be taken on an empty stomach? Okay, maybe you did. But did you know that grape seed extract inhibits the growth of gut-friendly lactobacillus acidophilus, and that they should be taken separately?

The truth is that we sometimes spend a small fortune on high quality supplements, only to neglect their full benefits by not taking them at the right time, or in the right combination. That's exactly why I made this website. Let's get started!

Build your own Vitamin Plan

  1. Mark the checkbox for each supplement that you are currently taking.
  2. When you're ready, click on "Generate Vitamin Plan".
  3. That's it! You will be able to make adjustments later if you want.

0 supplements selected

Tell us the health condition. We will review it, but we cannot guarantee if or when it will appear on the site.

Timing is everything

Many supplements are dependent on being taken at the right time, or with the right meal, for proper absorption. For example, fat-soluble vitamins such as vitamin D should be taken together with a high-fat meal. Stimulating supplements, such as rhodiola or ginseng, should avoid being taken too late in the day.

The perfect match

Some supplements are known to complement each other when taken together, either because one helps the other to be absorbed, or because their effects compliment each other. Well known combos include vitamin D3, vitamin K2 and magnesium, or quercetin and bromelain, but there are many others.

Incompatibilities

Likewise, some supplements can compete for absorption or react negatively if taken together. For example, calcium and magnesium compete for absorption, so they are best taken several hours apart, and fiber-heavy supplements such as psyllium husk should be taken by themselves, separate from all other supplements.

Potential additions

The Vitamin Plan will automatically detect if there is a recurring theme in the supplements that you are taking, and suggest a focused addition or two for that theme. For example, if your plan seems to be mostly centered around joint health, it may suggest adding glucosamine or collagen if you didn’t add them yet.

Remember

A balanced diet and a healthy lifestyle always come first, and supplements are meant to be just that: supplementary. While every effort has been made to ensure that the data on this page is accurate, said accuracy can never be guaranteed. The information provided is not medical advice, it is not intended to cover all possible interactions or adverse effects, and neither is it a substitute for the expertise of professional healthcare practitioners. You are always encouraged to do your own research, and to consult with your trusted doctor or pharmacist before taking any supplements.
