Frequently Asked Questions
Does it matter when you take supplements?
Yes, timing can significantly affect absorption. Fat-soluble vitamins (A, D, E, K) absorb best with dietary fat. Iron absorbs best on an empty stomach. B vitamins can disrupt sleep if taken at night. Magnesium may promote sleep if taken in the evening. Consistency matters more than perfect timing.
Which supplements should not be taken together?
Key combinations to avoid: calcium + iron (calcium blocks iron absorption), calcium + zinc (compete for absorption), iron + zinc (high doses compete), and calcium + thyroid medication (wait 4 hours). Vitamin C enhances iron absorption, so they work well together.
Should supplements be taken with food?
Fat-soluble vitamins (A, D, E, K), omega-3s, and multivitamins should be taken with food containing fat. Zinc and calcium absorb better with food. Iron, collagen, and probiotics are better absorbed on an empty stomach. B vitamins can be taken either way but are best with breakfast.
