Understanding the interactions, benefits, and safety of combining these two powerful supplements.

Melatonin SR
+
Multivitamin

Short answer

We found no direct interaction between Melatonin and Multivitamin in the sources below, but they share a caution.

Both have a note about blood thinners such as warfarin (see each one below).

Melatonin (slow release)

What it is: A slow-release form of melatonin, the hormone the brain makes in the dark to set your sleep-wake clock.

What the research says: Melatonin may help with jet lag and some circadian sleep problems. Sleep-medicine guidelines say there isn't enough evidence to recommend it for chronic insomnia.

Cautions

  • Short-term use seems safe for most people; long-term safety isn't known.
  • Older adults may feel drowsy the next day.

Medicines to check

  • Blood thinners and epilepsy: use only under medical supervision

Multivitamin

What it is: A combination of vitamins and minerals in one supplement.

What the research says: A multivitamin raises your daily nutrient intake; it's hard to show it prevents disease. It can't replace a varied diet.

Cautions

  • A basic multivitamin is unlikely to cause harm, but check your total intake if you also take other supplements or fortified foods.
  • Smokers should avoid multivitamins with large amounts of beta-carotene or vitamin A.

Medicines to check

  • Warfarin: talk to your clinician before any supplement with vitamin K
