  15 Vitamin B12-Rich Foods to Add to Your Diet Vitamin B12 is a small nutrient with an important job. Your body needs vitamin B12 for normal red blood-cell formation, neurological function and DNA synthesis. Yet your body cannot produce B12 on its own, so you need to obtain it through food or supplements. For most adults, the recommended daily amount is 2.4 micrograms (mcg). Requirements are higher during pregnancy and breastfeeding. The good news? You don't need complicated foods to get B12. Many everyday foods—including seafood, meat, eggs, dairy products and fortified foods—can contribute to your intake. Let's look at 15 practical sources of vitamin B12 and how they can fit into a balanced diet.

Why Am I Always Tired? 9 Sleep Problems and What Actually Helps

Waking up tired even after spending enough time in bed can be frustrating. You may fall asleep quickly but wake during the night, struggle to quiet your thoughts, or simply feel like your sleep isn't refreshing.

And you're not alone. According to the CDC, 30.5% of U.S. adults reported sleeping less than 7 hours on average in 2024. The CDC also recommends that most adults get at least 7 hours of sleep each night.

The good news is that improving sleep isn't always about finding a single magic solution. Your sleep schedule, light exposure, caffeine, stress, bedroom environment, exercise, and nighttime routine can all matter.

This guide explains nine common reasons sleep may not feel restorative—and what you can realistically do about them.


1. Your Sleep Schedule Is Inconsistent

Going to bed at 10 PM one night, midnight the next, and 2 AM on the weekend can make it harder to maintain a consistent sleep-wake rhythm.

Try keeping your bedtime and wake-up time as consistent as possible, including on weekends.

The CDC specifically recommends maintaining a regular sleep schedule.

Simple goal: Choose a realistic wake-up time and stick with it most days.


2. You're Getting Enough Hours—But Poor-Quality Sleep

Sleep isn't only about the number of hours you spend in bed.

You might technically sleep for seven or eight hours but still wake repeatedly during the night.

Common signs of poor sleep quality include:

  • Repeated nighttime awakenings
  • Difficulty falling asleep
  • Waking too early
  • Feeling tired despite spending enough time in bed

If these problems happen regularly, don't simply assume you need a stronger sleep supplement. Persistent sleep problems can sometimes be related to an underlying sleep disorder or another health condition. The CDC recommends discussing ongoing sleep problems with a healthcare professional.


3. Your Bedroom May Be Working Against You

Your sleeping environment matters more than many people realize.

A bedroom that's bright, noisy, hot, or uncomfortable can make restful sleep more difficult.

Consider making your bedroom:

Cool + Dark + Quiet + Comfortable

You can also silence unnecessary phone notifications and keep bright screens away from your sleeping area.

The CDC recommends a quiet, relaxing and cool bedroom environment.


4. Your Evening Screen Routine May Be Too Stimulating

Scrolling through social media, watching intense videos, answering work messages, or staying on your phone right until bedtime can make it harder to transition into sleep.

Instead, create a short wind-down period.

For example:

60 minutes before bed: finish demanding work
30 minutes before bed: reduce electronic-device use
Before bed: dim the lights and follow a relaxing routine

The CDC recommends turning off electronic devices at least 30 minutes before bedtime.


5. Caffeine May Be Lasting Longer Than You Think

Coffee isn't necessarily a problem.

But drinking caffeine later in the day can interfere with sleep for some people.

If you're struggling with sleep, experiment with moving your final caffeinated drink earlier in the day.

Instead of asking:

"Can I fall asleep after drinking coffee?"

Ask:

"Is my sleep actually refreshing after drinking coffee that late?"

That difference matters.


6. Stress Can Keep Your Brain Alert

Sometimes your body is tired but your mind isn't ready for sleep.

Tomorrow's meeting.

Money concerns.

Family responsibilities.

An unfinished project.

A long list of things you don't want to forget.

Instead of trying to force yourself to sleep, create a simple mental "shutdown" routine.

Try writing down:

Tomorrow's priorities:




Then give yourself permission to stop solving tomorrow's problems tonight.

Relaxation activities such as breathing exercises, stretching, meditation, or journaling can also become part of a consistent wind-down routine.


7. You're Not Getting Enough Daytime Activity

Your sleep routine begins long before bedtime.

Regular physical activity can support healthy sleep, while spending most of the day sitting may make it harder for some people to feel naturally ready for bed.

A simple starting point is a daily walk.

You don't need an extreme workout.

Consistency matters more than intensity.

The CDC recommends regular physical activity as part of healthy sleep habits.


8. Your Nighttime Routine Is Missing

Your brain learns patterns.

If your evenings are different every night, it can be harder to establish a predictable transition into sleep.

Try creating the same sequence most nights:

Dim lights → Put away screens → Hygiene → Relaxing activity → Bed

The goal isn't perfection.

The goal is repetition.

Over time, the routine can become a signal that your day is ending.


9. You May Be Looking for Additional Sleep Support

Lifestyle habits should be the foundation of a healthy sleep routine.

But some adults also explore dietary supplements as an additional option.

One product you may come across online is YU SLEEP, a liquid sleep-support supplement.

According to the manufacturer's current information, YU SLEEP contains a combination of ingredients including red tart cherry extract, GABA, L-theanine, lemon balm, apigenin, 5-HTP, magnesium glycinate, vitamins B6 and B12, and melatonin.

The manufacturer describes it as a sleep-support formula intended for adults who want help with falling asleep, staying asleep, or waking feeling refreshed.

What makes the formula different?

Rather than relying on one ingredient, YU SLEEP combines several ingredients intended to support different aspects of a nighttime routine.

For example:

  • L-theanine is commonly used in products designed around relaxation.
  • Magnesium plays many roles in normal body function.
  • Melatonin is involved in regulating the sleep-wake cycle.
  • Tart cherry extract is another ingredient used in sleep-focused formulas.
  • GABA, lemon balm and apigenin are included as part of the manufacturer's relaxation-focused formula.

However, it's important not to confuse evidence about an individual ingredient with proof that the finished YU SLEEP product will produce a particular result. Individual responses can vary, and supplement formulations and amounts should always be checked on the current product label.


Is YU SLEEP Right for Everyone?

Not necessarily.

A supplement shouldn't replace evaluation of an ongoing sleep problem.

If you regularly have difficulty falling asleep, repeatedly wake during the night, feel excessively sleepy during the day, or suspect you may have a sleep disorder, talk with a healthcare professional.

The CDC notes that conditions such as insomnia and sleep apnea can interfere with healthy sleep and recommends discussing persistent sleep problems with a healthcare provider.

If you take medication, have a medical condition, are pregnant or breastfeeding, check with your healthcare professional before using a sleep supplement.


What Should You Try First Tonight?

Before buying anything, try this simple checklist:

☐ Keep your wake-up time consistent
☐ Get some daylight during the day
☐ Get regular physical activity
☐ Avoid caffeine later in the day if it affects your sleep
☐ Reduce screen use before bedtime
☐ Keep your bedroom dark, quiet and comfortable
☐ Create a relaxing bedtime routine
☐ Give yourself enough time for sleep
☐ Keep a simple sleep diary if problems continue

These habits are inexpensive—and they're a much better starting point than relying entirely on a supplement.

Frequently Asked Questions

How many hours of sleep do adults need?

The CDC recommends at least 7 hours for adults ages 18–60. Requirements vary somewhat with age.

Why do I wake up tired after 8 hours?

Sleep quality can matter as much as time spent in bed. Repeated awakenings, an inconsistent schedule, an uncomfortable environment, stress, caffeine and possible sleep disorders can all contribute to unrefreshing sleep.

Is YU SLEEP a medication?

YU SLEEP is marketed as a dietary supplement, not as a prescription medication. Always read the current product label and consult a healthcare professional if you have questions about whether its ingredients are appropriate for you.

Can a sleep supplement replace good sleep habits?

No. Healthy sleep habits should remain the foundation. Supplements should not be viewed as a substitute for adequate sleep, a consistent routine, or medical evaluation when needed.


Final Thoughts

Better sleep doesn't usually come from one magic trick.

Start with the basics:

consistent timing + enough sleep + daytime activity + less evening stimulation + a comfortable bedroom.

If you've built those habits and are still looking for additional support, you can research products such as YU SLEEP and decide whether the ingredients and formulation fit your needs.

The goal isn't simply to spend more time in bed.

The goal is to wake up feeling ready for the day.
