We often hear the phrase “you’re within the normal range” when it comes to lab work—but what if those “normal” levels aren’t actually optimal for your health?
A new study is raising important questions about one particular nutrient: vitamin B12. Especially when it comes to brain health and aging.
Let’s take a look at what this means—and what you can do to protect your brain and your energy.
🧠 The Brain-B12 Connection
Vitamin B12 is essential for:
- Brain function and focus
- Nerve health
- Red blood cell production
- DNA synthesis
But here’s what’s new:
A recent study on older adults found that low-normal levels of B12 were still linked to slower cognitive processing and unhealthy changes in the brain—even when those levels technically fell within the “normal” lab range.
This suggests that what’s considered “normal” may not be optimal, especially as we age.
🧬 Who’s at Risk for B12 Deficiency?
Several groups are more likely to have low or borderline B12 levels, including:
✔️ Adults over 50
✔️ People with low stomach acid or gut issues (like IBS or Crohn’s)
✔️ Vegans and vegetarians
✔️ Anyone taking acid blockers (PPIs) or metformin
If you fall into one of these categories, it’s a good idea to talk to your provider about a more thorough evaluation.
In addition to a standard serum B12 test, ask about:
- Methylmalonic acid (MMA)
- Homocysteine
These markers provide a more complete picture of how your body is actually using B12—not just how much is circulating in your blood.
🍄 Adaptogenic Mushrooms: Natural Support for Stress and Energy
Let’s shift gears and talk about something that can help if you’re feeling a little… frazzled.
Adaptogenic mushrooms—like Reishi, Shiitake, Maitake, and Cordyceps—are known for their ability to support:
- Stress resilience
- Immune function
- Balanced energy
- Hormonal harmony
How to Use Them:
- Cook with them: Add fresh or dried mushrooms to soups, stir-fries, or broths.
- Take supplements: Look for quality powders, capsules, or mushroom blends.
- Try infused beverages: Mushroom lattes, teas, and even coffee alternatives are easy to find now.
And don’t worry—these are not the hallucinogenic kind. They’re completely legal, safe, and increasingly well-researched in the world of functional medicine.
💡 Quick Mindset Tip: Control What You Can
Stress often stems from trying to manage things we simply can’t.
The weather. The news. Other people.
Instead, focus on what’s within your control:
✅ Your sleep habits
✅ The food you eat
✅ Movement, breathwork, boundaries, mindset
Try this when you feel stressed:
- Notice the feeling (without judgment)
- Ask: “Is this within my control?”
- Act: Choose one supportive action (walk, talk, rest, breathe)
Over time, these small shifts build true stress resilience—the kind that keeps your mind sharp and your body strong.
Final Thoughts
Optimal health is rarely about doing one “big” thing—it’s about consistently making better choices over time.
Whether it’s getting your B12 levels properly evaluated or adding adaptogens to your routine, small actions matter.
