Vitamins You Should Avoid Combining (and the Pairings That Work Better)
Vitamins You Should Avoid Combining: If you’ve ever taken all your supplements at once, you’re not alone — but you may be missing out on benefits without realising it.
Some vitamins and minerals block each other. Others work far better together. And certain combinations dramatically improve absorption.
Here’s what to avoid, what to pair, and how TRINITY Multi-Nutrients times everything correctly.
❌ Vitamins You Should NOT Take Together
1. Iron + Calcium
These compete for the same absorption pathway → iron absorption drops.
Best practice:
Iron in the morning, calcium later in the day.
2. Magnesium + Iron
Magnesium reduces iron uptake.
Best practice:
Magnesium at night, iron in the morning.
3. Zinc + Copper
High doses of one reduce absorption of the other.
Best practice:
Take at different times.
4. Fat-Soluble Vitamins Without Food
Vitamins A, D3, E, and K need dietary fat to absorb properly.
Best practice:
Take with lunch or any meal containing healthy fats.
5. High-Dose Vitamin C + Vitamin B12
In large doses, vitamin C may reduce B12 bioavailability.
Best practice:
Separate when megadosing.
✔ Vitamins & Minerals That Work BETTER Together
Iron + Vitamin C
Vitamin C enhances iron absorption.
This pairing appears in TRINITY’s Morning Formula.
