Vitamin B12 & Folic Acid Injections in Newport Beach
Oral supplements are absorbed inconsistently. Injections bypass the digestive system entirely — delivering nutrients directly into the bloodstream at full potency, with effects that most patients notice within 24 to 48 hours.
Vitamin B12 and folic acid are among the most commonly deficient nutrients in adults — particularly those on plant-based diets, patients taking metformin or certain acid-reducing medications, and anyone with compromised gut absorption. Deficiency in either affects energy metabolism, neurological function, red blood cell production, and cellular repair. Injectable delivery ensures complete absorption regardless of gut function.
At Plump Medical Spa in Newport Beach, vitamin injections are available as a standalone wellness service and as an add-on to any aesthetic treatment. At $75 per injection, they are one of the most accessible and immediately felt wellness treatments available at the practice.
Injectable B12 and folic acid are not a substitute for diagnosing and treating an underlying deficiency. Patients with symptoms of deficiency — fatigue, numbness, cognitive changes — should have their levels checked before relying on injections alone. Dr. Mortazavi can order relevant labs at consultation and discuss whether injections are appropriate as part of a broader wellness approach.
The two injections offered at Plump
Vitamin B12 (Methylcobalamin)
B12 is essential for red blood cell formation, neurological function, DNA synthesis, and energy metabolism. Deficiency causes fatigue, brain fog, weakness, and over time can lead to neurological damage. Injectable methylcobalamin — the active, bioavailable form of B12 — is absorbed completely regardless of gut function or intrinsic factor status.
- Energy and fatigue reduction
- Cognitive clarity and mood support
- Neurological health maintenance
- Red blood cell production
- Metabolism and cellular repair
Folic Acid (Vitamin B9)
Folic acid is essential for DNA synthesis, cell division, and homocysteine metabolism. Deficiency is common in pregnancy, in patients on certain medications (methotrexate, metformin, anticonvulsants), and in individuals with the MTHFR gene variant that impairs folate conversion. Injectable delivery ensures complete availability regardless of absorption or conversion capacity.
- DNA synthesis and cell repair
- Homocysteine regulation
- Support during pregnancy or pre-conception
- Medication-related deficiency management
- Overall cellular health
Why injection over oral supplementation
Oral B12 and folic acid supplements are widely available — the question is not whether supplementation is valuable but whether oral delivery achieves adequate absorption for a given patient.
B12 absorption from oral supplements requires intact gastric acid production and a protein called intrinsic factor produced by the stomach lining. Patients with reduced stomach acid — from age, proton pump inhibitor use, or gastric surgery — absorb a fraction of oral B12 regardless of dose. Patients with pernicious anemia produce no intrinsic factor and cannot absorb oral B12 at all. Injectable B12 bypasses this system entirely and is absorbed at 100% bioavailability.
Folic acid oral absorption is generally good in most people, but patients with the MTHFR gene variant have impaired ability to convert folic acid to its active form (methylfolate). For these patients, injectable folate delivered in active form provides what oral supplementation cannot reliably achieve.
Vitamin injections are one of the simplest and most immediately felt additions to a wellness routine — particularly for patients who have been supplementing orally without noticing consistent benefit. Dr. Mortazavi’s background in internal medicine informs how he approaches nutrient status — as a clinical question, not a wellness trend. For patients wanting labs alongside their injections, that conversation is available at consultation.
Frequently asked questions
Why get B12 injections if I already take oral B12?
Oral B12 absorption depends on stomach acid and a protein called intrinsic factor produced by the stomach lining. Many adults — particularly those over 50, those on proton pump inhibitors, and those who have had gastric surgery — absorb only a small fraction of oral B12 regardless of the dose on the label. Injectable B12 bypasses the digestive system entirely and is absorbed at 100% bioavailability. Patients who supplement orally without noticing improvement often respond well to injectable delivery.
How quickly will I feel the effects?
Many patients notice improved energy and clarity within 24 to 48 hours of a B12 injection, particularly those who were deficient. Folic acid effects are less acutely perceptible but accumulate with consistent use. Patients who are severely deficient may notice more dramatic improvement than those who are mildly low or within normal range.
How often should I get vitamin injections?
This depends on the patient’s baseline status, diet, and why they are supplementing. For general wellness maintenance, monthly injections are common. For patients with known deficiency or absorption issues, more frequent initial injections followed by maintenance dosing may be appropriate. Dr. Mortazavi can advise on frequency based on the patient’s specific situation.
Can I get a vitamin injection at the same appointment as my Botox or filler?
Yes — vitamin injections are available as an add-on to any treatment at Plump. Many patients add a B12 or folic acid injection to their aesthetic appointments as a routine wellness component. It adds only a few minutes to the appointment and is priced at $75 regardless of what else is being done.
Is folic acid injection different from the folic acid in prenatal vitamins?
Folic acid in prenatal vitamins is the synthetic form taken orally — it requires conversion in the body to its active form (methylfolate) before it can be used. Patients with the MTHFR gene variant have impaired ability to make this conversion, which means oral folic acid may not be adequately utilized. Injectable folate can be formulated in the active methylfolate form, bypassing the conversion step entirely. If you have a known MTHFR variant, mention this at consultation.
How much do vitamin injections cost at Plump?
Vitamin B12 and folic acid injections at Plump Medical Spa in Newport Beach are $75 per injection — the same price whether taken standalone or as an add-on to another treatment at the same appointment.
