Let’s talk about 9 vitamins that are proven to help you get better ZZZs.

- But new research shows it might help control your body’s sleep-wake cycle too.
- You can get vitamin A from:
- Eggs
- Dark leafy greens like spinach and Swiss chard
- Orange foods like carrots, squash, mango, and papaya

- Good sources of vitamin B1 are:
- Lean meats
- Seafood

- Whole grains like brown rice and whole wheat bread
Vitamin B6
- Vitamin B6 can lead to more peaceful sleep by:

How Much of These Vitamins Do You Need?
The exact amount of each vitamin you need per day depends on your age, gender, and other factors. But let’s keep it simple!
Aim to eat foods with 3-4 of these sleep vitamins daily, especially with dinner. Many foods have several of them, so it’s easier than you think.
If your diet is restricted or you don’t eat a lot of vitamin-rich foods, consider a multivitamin. Look for one with no more than 100% of the daily value for each vitamin and mineral. Third-party labels like NSF or USP also mean it’s a quality supplement.
But always check with your doctor before starting supplements or making big changes to your diet and lifestyle.
Here’s a handy table summarizing the key sleep-promoting vitamins and top food sources:
| Vitamin | Top Food Sources |
| A | eggs, spinach, carrots, squash |
| B1 | lean meats, seafood, legumes, whole grains |
| B6 | chickpeas, bananas, potatoes, lean meats, fish |
| B9 | spinach, beans, peas, avocado, asparagus |
| B12 | seafood, lean meats, dairy, eggs |
| C | citrus, berries, bell peppers, broccoli |
| D | fatty fish, egg yolks, sunlight |

Foods and Drinks to Avoid Before Bed
Some things can actually make it harder to sleep well. Try to stay away from:
- Alcohol – makes it harder to sleep through the night
- Caffeine – found in coffee, tea, chocolate; stimulates your brain
- Added sugar – gives you an energy buzz when you need to wind down
Skip the coffee and black/green tea after noon. Have herbal tea instead. Don’t have alcohol, chocolate, or sugary foods 2-3 hours before bedtime.
The Bottom Line
Struggling to sleep well is super frustrating. But you have the power to improve your sleep!
Along with good sleep habits, eating foods high in certain vitamins can make a real difference. Vitamins A, B, C, D, E, and K all play a role in helping you get those precious ZZZs. And avoiding alcohol, caffeine and sugar before bed helps too.
Focus on vitamin-rich whole foods, consider a multivitamin if needed, and you’ll be on your way to more restful, restorative sleep in no time. Sweet dreams!
