Can I Take Vitamins at Night?
Quick Answer
Most vitamins are fine at night. B vitamins and vitamin D might energize some people (take morning). Magnesium is BETTER at night (helps sleep). Fat-soluble vitamins need food whenever you take them. Overall: timing matters less than consistency.
Key Points
- Magnesium is ideal at night (aids sleep)
- B vitamins may energize (morning is safer)
- Fat-soluble vitamins need food, not specific time
- Consistency matters more than perfect timing
- If in doubt, take with dinner
Detailed Answer
BETTER AT NIGHT:
• Magnesium: Promotes relaxation and sleep. Evening is ideal. • Calcium: Some evidence for better absorption at night. • Melatonin: Obviously (30-60 min before bed). • Glycine: Improves sleep quality.
BETTER IN MORNING:
• B vitamins: Can be energizing for some people. May disrupt sleep. • Vitamin D: Mimics sunlight exposure. Some find it energizing. • Iron: Empty stomach absorbs best (morning before breakfast). • Caffeine/stimulant supplements: Obvious.
DOESN'T MATTER:
• Vitamin C: Anytime • Zinc: With food whenever convenient • Fish oil: With any meal • Most herbs: Consistency matters more than timing
FAT-SOLUBLE VITAMINS (A, D, E, K):
Need dietary fat for absorption. Take with a meal that has some fat, whether that's breakfast, lunch, or dinner. Time of day doesn't affect absorption, but food presence does.
Evidence Quality
Some quality studies, more research helpful

B vitamins and vitamin D can be slightly stimulating for some people. If you notice sleep issues, move them to morning. Most people don't have problems though.
