Vitamin B12: Why “Normal” Isn’t Always Optimal ☢️
by Ronnie Robertson – Health & Nutrition Coach | Empowerment Coach | Founder of Nuclear Nutritition ☢️
When it comes to energy, focus, and recovery, Vitamin B12 is one of the most overlooked nutrients your body depends on. Yet, every day I meet people who are technically “in the normal range” — but still feel exhausted, foggy, and burnt out.
Here’s the truth: being in range doesn’t mean you’re thriving.
Most standard lab tests only measure total B12 in the blood, which doesn’t reflect how much of that B12 is actually being absorbed and utilized by your cells. This is called cellular B12 insufficiency, and it’s one of the most common yet misunderstood deficiencies in modern health care.
Why Standard Labs Miss the Mark
Traditional testing doesn’t always show the full picture. You can have “normal” serum B12 levels but still have functional deficiency if your cells can’t properly convert and use B12 — especially if you have a MTHFR gene mutation.
MTHFR (Methylenetetrahydrofolate Reductase) is an enzyme that plays a major role in methylation — a process essential for detoxification, neurotransmitter production, and energy metabolism. If you carry an MTHFR variant, your ability to activate B12 and folate is reduced, meaning you need the methylated, bioactive form (Methylcobalamin or Adenosylcobalamin) to truly feel the benefits.
Who Needs More B12?
Even without MTHFR, many people are running on low reserves. If you’re:
- Highly active or training regularly
- Under chronic stress
- Recovering from illness or surgery
- Not sleeping or recovering well
- Vegan or vegetarian
- Experiencing brain fog, fatigue, or low motivation
…then your B12 demands are significantly higher.
B12 Deficiency and Anemia
Low B12 can cause megaloblastic anemia, a condition where red blood cells become enlarged and oxygen delivery drops. Symptoms often show up as fatigue, dizziness, shortness of breath, or pale skin — but can also mimic anxiety, depression, or neuropathy. Unfortunately, these symptoms are often misdiagnosed, leading to unnecessary prescriptions instead of addressing the real cause: low active B12.
The Benefits of Active B12
The BioActive forms (Methylcobalamin, Hydroxocobalamin, Adenosylcobalamin) go beyond energy — they support your body at the cellular level by:
- Boosting natural energy production
- Supporting mood and mental clarity
- Enhancing red blood cell formation and oxygen delivery
- Promoting nerve and brain health
- Supporting methylation and detoxification pathways
- Improving sleep quality and recovery
- Reducing homocysteine (a marker of cardiovascular risk)
- Aiding muscle repair and endurance
B12 for Real-Life Performance
Many of my clients and customers use the B12 Spray daily for steady energy and brain support — then include a B12 Shot weekly, every other week, or whenever they need an extra boost. It’s a safe, powerful, and empowering way to take control of your health and performance.
Whether you’re an athlete, entrepreneur, or someone just trying to feel like yourself again, B12 can make a world of difference.
