Don’t Let B12 Deficiency Steal Your Energy, Focus or Joy

By Dr. Paul Bernitt, Board-Certified Director of Wellness

“But He was wounded for our transgressions, He was bruised for our iniquities: the chastisement of our peace was upon Him;
and with His stripes we are healed.”

Isaiah 53:5 KJV

Learn how TriVita’s B-12 supplements can support your energy, memory, mood and heart—especially after age 50.

Do you feel more tired than you used to? Have you noticed your memory slipping or your mood changing? Many people believe it’s just a normal part of getting older—but it may be something more. Your body needs vitamin B12 and folate (vitamin B9) every day to function at its best. These nutrients are essential for your energy, your brain, your mood and your heart. If you’re low on B12, your body and mind will feel it.

Why Your Body Needs B12 and Folate

B12 and folate work together in the body to support some of your most vital functions. They help:

Break down protein and fat for energy
Build red blood cells and prevent anemia
Support your heart and blood vessels
Keep your nerves working properly
Make neurotransmitters that affect your mood
Support memory, focus and clear thinking

All of TriVita’s slow-dissolve B-12 products include both B12 and folate, because your body needs them to function well—especially as you age.

Fatigue Isn’t Just a Sign of Aging

If you often feel weak, tired or out of breath, you might not be getting enough B12. As we get older, our bodies don’t absorb B12 from food as easily. That’s why supplementing B12 is so important.

B12 helps your body make hemoglobin, a part of your red blood cells that carries oxygen. If you don’t have enough hemoglobin, your cells don’t get enough oxygen—and that’s when you start feeling exhausted. Studies show that B12 supplementation can help increase hemoglobin levels and boost your energy.¹

Brain Fog, Forgetfulness and Mood Swings? Low B12 Could Be the Cause

Low B12 levels are linked to:

Trouble focusing
Memory loss
Mental confusion
Forgetfulness
Mood changes like anxiety and depression

B12 helps your brain produce dopamine and serotonin, which are the “feel good” chemicals that support a balanced mood. If your B12 is low, you might feel down, stressed or more emotional than usual. In fact, B12 deficiency has been linked to a higher risk of depression.²

Protect Your Brain as You Age

Low B12 over time can even lead to brain shrinkage, especially in older adults with mild cognitive impairment. But there’s good news: research shows that taking B vitamins like B12 and folate may slow the rate of brain atrophy by lowering levels of homocysteine, a harmful substance in the blood.³

Are Your Nerves Telling You Something?

Do you ever feel tingling, numbness or “pins and needles” in your hands or feet? This can be a sign that your nerves aren’t working properly—and low B12 could be the reason. As we age, nerve damage increases the risk of losing function, balance and mobility. Taking B12 helps support the health of your nervous system and protect your ability to stay active and independent.⁴

Get B Vitamins Daily

B vitamins are water soluble, which means they dissolve in water and are not stored in the body. Because they’re used up daily and flushed out through urine, a steady supply is necessary to keep vital systems running smoothly. Without daily replenishment, key functions like energy production, brain function, mood regulation, red blood cell formation and nerve health can begin to break down.

Is B12 Deficiency Impacting Your Life?

Check all that apply:

☐ Rapid breathing or shortness of breath

☐ Rapid heartbeat

☐ Feeling weak or tired

☐ Muscle weakness

☐ Feeling down or depressed

☐ Problems with memory or focus

☐ Numbness in hands or feet

☐ Pins and needles sensations

If you checked several boxes, your body may be signaling that it’s time to boost your B12.
