Restores Energy at the Cellular Level
B12 is a cofactor in the methylation cycle and electron transport chain. Correcting deficiency reignites ATP production, so fatigue lifts at the root, not just masked.

Why B12 Deficiency Causes Fatigue and Fog, and How IV Therapy Restores It
B12 deficiency undermines energy production, nerve function, and mood. IV supplementation restores cobalamin levels fast when malabsorption or dietary gaps are the culprit.
Book a Session →What to Expect
- ✓B12 is essential for myelin formation, red blood cell maturation, and DNA synthesis
- ✓Deficiency causes fatigue, brain fog, numbness, and mood changes
- ✓Malabsorption (celiac, Crohn's, IBS) blocks oral B12 uptake
- ✓Vegan and vegetarian diets lack dietary cobalamin sources
- ✓Metformin and PPIs interfere with B12 absorption
- ✓IV infusion bypasses GI barriers and replenishes stores efficiently
Bypasses GI Malabsorption
IV infusion works even when oral supplements fail
Durable Stores
Your body retains B12 for months; regular infusions prevent relapse
Benefits & Outcomes
Reverses Neurological Symptoms
Prolonged deficiency causes peripheral neuropathy, numbness, and cognitive fog. Early IV repletion halts progression and can reverse early signs. Nerve repair takes time, but symptoms often improve within weeks.
Improves Mood and Sleep Quality
B12 supports synthesis of serotonin, dopamine, and GABA, neurotransmitters that regulate mood and sleep. Deficiency contributes to depression and insomnia; repletion often resolves both.
Faster Correction Than Oral Supplements
Oral B12 absorption is limited by intrinsic factor and GI health. IV delivery builds your stores over an initial series of infusions, while oral supplements alone may take months.
Frequently Asked Questions
How do I know if I have B12 deficiency?▾
Symptoms include fatigue, brain fog, numbness or tingling, mood changes, and shortness of breath. A blood test measuring serum B12 or methylmalonic acid levels confirms it. Ask your physician or our office about testing before starting therapy.
Can IV B12 work if I'm on metformin?▾
Metformin impairs B12 absorption in the GI tract, making IV therapy ideal. Once your B12 stores are repleted with infusions, you can maintain with IM injections or oral supplements, but IV restores reserves faster.
How long do B12 IV benefits last?▾
Effects vary. Energy often peaks within 24-48 hours and sustains for 2-4 weeks. Your body depletes B12 stores gradually, so regular infusions (monthly or as needed) maintain benefits. We help you find your optimal schedule.
Is B12 IV therapy safe long-term?▾
B12 is water-soluble and non-toxic. Excess is excreted in urine. Long-term B12 therapy is widely used in integrative and functional medicine. Dosing and frequency should be personalized to your needs.
Should I stop taking oral B12 if I get IV infusions?▾
Not necessarily. Some clients use IV infusions to rebuild stores, then maintain with oral supplements or monthly injections. Others prefer regular IV therapy. We recommend discussing your maintenance plan after your initial series.
