Select a nutrient to see its compatibility with other vitamins and minerals. Learn which combinations boost absorption and which should be taken separately.
Select a nutrient and click "Check Compatibility" to see detailed compatibility information.
Note: Based on scientific research on nutrient synergy and antagonism. For personalized advice, consult a healthcare professional.
What is Vitamin & Mineral Compatibility?
Vitamins and minerals do not work in isolation. Some nutrients enhance each other's absorption and effectiveness (synergy), while others compete or interfere (antagonism). Understanding these interactions is key to optimizing your supplement routine [citation:1].
Good compatibility (synergy): Some nutrient pairs work together to boost absorption. For example, Vitamin C helps the body absorb iron, and Vitamin D improves calcium absorption. Taking these together can maximize their benefits [citation:1].
Poor compatibility (antagonism): Some nutrients can block each other's absorption. For instance, calcium and iron compete for the same pathways, and zinc and folate can form an insoluble complex, reducing both. These should be taken at different times, ideally 4–6 hours apart [citation:1].
Based on scientific research, this calculator provides compatibility information for: Vitamin A, B-complex vitamins (B1, B2, B3, B5, B6, B9, B12), Vitamin C, D, E, K, and minerals including calcium, iron, magnesium, zinc, copper, phosphorus, and selenium [citation:1].
