Most everyday supplements can be taken together safely — and some actually work better as a pair. A few are best spaced apart. Here's how to combine sensibly.
Great combinations
Some nutrients complement each other: vitamin C helps your body absorb iron, and vitamin C also contributes to normal collagen formation — a popular beauty pairing. Protein and creatine are a classic training duo.
Best spaced apart
Very high doses of certain minerals can compete for absorption — for example large amounts of calcium and iron are often taken at different times. If you take several minerals, splitting them across the day can help.
Calming vs energising
Many women take energising nutrients (B vitamins) in the morning and calming ones like magnesium in the evening — not for safety, but to match how they feel through the day.
The key rule: avoid doubling up
Check labels so you don't exceed safe totals when combining a multivitamin with separate products.
