B12 Shots in Beverly Hills & Los Angeles

Vitamin B12 injections from $35, same-day and walk-in, Monday–Friday at our Beverly Hills office. Each shot takes about five minutes and is given by our nursing team under the supervision of David Nazarian, MD, Board Certified in Internal Medicine. If you have never had your B12 level checked, we can test it at the same visit.

Who B12 injections help most

B12 shots make the biggest difference for people who are low in vitamin B12 or who cannot absorb it well from food or pills. Common reasons include:

• Pernicious anemia or low stomach acid
• Gastric bypass, sleeve gastrectomy or other stomach and bowel surgery
• Crohn’s disease, celiac disease and other malabsorption conditions
• Long-term metformin, acid-reducing medication (PPIs, H2 blockers) or nitrous oxide exposure
• Vegan or strict vegetarian diets
• Adults over 50, whose absorption naturally declines

Symptoms that can point to low B12 include tiredness, pale skin, numbness or tingling in the hands and feet, balance problems, a sore tongue and memory or mood changes. These symptoms have many causes, so if they are new or persistent we check your level rather than guess.

What to expect at your visit

1. Quick screening: we review your medications, allergies and any prior lab results.
2. Labs if needed: a blood draw for B12 and related tests when deficiency is suspected or you have never been tested.
3. The injection: a small intramuscular shot; most people feel only a brief pinch.
4. A plan: how often to return depends on your levels and the reason you are low. Some patients need a short loading series; others do well with occasional maintenance shots or oral B12.

How often can you get B12 shots?

For documented deficiency, treatment often starts with several injections over the first weeks, followed by monthly or less frequent maintenance. People with normal absorption and normal levels usually do not need regular shots. Your clinician sets the schedule from your labs and symptoms.

B12 shots for energy and weight loss: what the evidence shows

Correcting a true deficiency can noticeably improve fatigue, anemia and nerve symptoms. In people whose B12 is already normal, studies have not shown that extra injections increase energy or cause weight loss. If weight management is your goal, ask about our lipotropic (MIC + B12) injections as part of a broader plan, or read B12 shots and weight loss: what the evidence shows.

Safety and side effects

B12 is water-soluble and generally very well tolerated. Possible effects include soreness or bruising at the injection site, mild diarrhea, itching and, rarely, allergic reactions. Tell us if you have Leber’s disease (an inherited eye condition), a cobalt or cobalamin allergy, or are being treated for anemia, because these change how we treat.

B12 shot pricing

Vitamin B12 injections start at $35. B-complex injections also start at $35. Lab testing, when needed, is quoted before your visit. See the full IV therapy and injection price list.

B12 shot, sublingual or pills?

Form	Best for	Trade-off
Intramuscular B12 shot	Pernicious anemia, gastric surgery, malabsorption, fast correction of deficiency	Needs an office or mobile visit
Sublingual (under the tongue)	Mild deficiency in people who absorb normally	Absorbs much like a swallowed pill; not a substitute when absorption is impaired
Oral tablets	Diet-related low B12, long-term maintenance	Large daily doses needed when absorption is reduced

Research shows high-dose oral B12 can correct many deficiencies, but injections work regardless of how well your gut absorbs it, which is why they remain the standard after stomach surgery or with pernicious anemia. We’ll recommend the simplest option that will actually work for you.

Does a B12 shot hurt?

Most patients feel a quick pinch. The injection uses a small needle in the upper-arm muscle and takes a few seconds; mild soreness can last a day. Some clinics give B12 under the skin (subcutaneously) instead of into the muscle; both routes are effective, and we choose based on your dose and preference.
