Do You Still Feel Tired — Even After a Good Night's Sleep?

By Paul Bernitt, Board-Certified Doctor of Holistic Health

You eat well. You try to get enough rest. You challenge your mind. Maybe you even exercise. But for some reason, you still feel tired, foggy and unmotivated. Wondering what’s going on?

You’re not alone. Many people experience fatigue and lack of mental clarity, even when they do “everything right.” The reality is, you could be missing a vital nutrient your body depends on every single day.

Let’s explore what may be going on—and what you can do to get your energy and focus back.

The Hidden Deficiency That Could Be Draining You

Most people have heard of Vitamin B12, but many don’t realize how essential it is to how we feel every day. B12 is not just a “nice-to-have” vitamin—it plays a powerful role in:

• Turning food into usable energy
• Supporting the nervous system
• Making red blood cells
• Protecting memory, focus and mood
• Helping the brain communicate properly
• Balancing homocysteine, a marker of heart health

Without enough B12, you may feel weak, tired, forgetful or foggy—even when you're sleeping well and eating healthily.

Why B12 Deficiency Is More Common Than You Think

As we age, our bodies don’t absorb B12 from food as easily if we have digestive issues. Another challenge is that stomach acid declines, which makes it harder for B12 to get into the bloodstream where it’s needed. This is even more common in people over 50, those who take acid-blocking medications, and people with digestive issues.

Also, the typical American diet consisting of ultra-processed foods doesn’t provide enough of the active, bioavailable forms of B12 the body needs—especially if you eat less red meat or follow a plant-based lifestyle.

That’s why so many people suffer from low B12 without realizing it.

How Do You Know If You're Low on B12?

Here are some signs and symptoms that might point to a lack of B12:

• Constant fatigue
• Brain fog or trouble concentrating
• Mood changes, like feeling anxious or down
• Tingling or numbness in the hands or feet
• Trouble with balance or coordination
• Weakness, dizziness or heart palpitations

If these sound familiar, you may benefit from boosting your B12 levels.

The TriVita Solution: Fast-Acting, High-Quality B12 Formulas

At TriVita, we offer two science-supported ways to get the B12 your body may be craving:

• Original B-12 – Developed by Alfred Libby, this original patented formula delivers B12, B6, and folate in a dissolvable tablet for rapid absorption.
• Super B-12 – An advanced formula that gives you more B12, B6 and folate, plus ginseng, a natural stimulant.

Both are taken under the tongue, bypassing the digestive system and going directly into the bloodstream where they can make a real difference.

Many TriVita Members say that within days or weeks, they start to notice more clarity, steady energy and better focus—without relying on caffeine or stimulants.

“I was really needing energy in my life, and I was even starting to miss work from it. Then one day I was watching TV and saw them advertising the Original B-12, and I ordered some. Within two weeks I was a totally different person. I continue to tell people all the time about how amazing the Original B-12 is, and I give it a 5-star rating.”
– Glenda B.

“I love the Super B-12 for energy. I have a mutated gene that makes it difficult for my body to process B12. However, TriVita’s Super B-12 has methylcobalamin, and that allows my body to process it. I give the Super B-12 a 10-star rating out of 5 stars.”
– Hazel A.

“My doctor ran a test to measure my homocysteine levels, and the results stated that it was too high. I started taking Alfred Libby’s Original B-12 formula every day after that. A month later I went back and took the test again, and my homocysteine levels were normal. I give the Original B-12 no less than 4 stars.”

Other Natural Ways to Support Your Energy and Focus

While B12 is foundational, here are a few lifestyle habits that can help boost your mental clarity and energy:

• Move your body daily. Even a 20-minute walk increases circulation and boosts mood.
• Hydrate. Dehydration can drain your energy fast. Aim for half your body weight in ounces of water each day, and include electrolytes like TriVita’s ElectroHydrate drink mix.
• Play brain games like Lumosity and Elevate to improve clarity by challenging focus and memory.
• Prioritize sleep quality. Wind down without screens and aim for 7–8 hours per night.
• Eat nutrient-dense foods. Leafy greens, berries, healthy fats and lean proteins help fuel your brain.
• Manage stress. Deep breathing, prayer, or quiet time in nature can help reset your mind.
• Limit sugar and ultra-processed foods. These can cause energy spikes and crashes.

Even with all these tools, B12 remains a foundational nutrient—especially if your body isn’t absorbing enough through food alone.
