Vitamin B12 (methylcobalamin) is a water-soluble vitamin that is naturally found in animal products such as poultry, beef, fish, eggs, and dairy. After consumption, the body’s intestines produce a protein called intrinsic factor (IF) that binds with vitamin B12 to allow these nutrients to be properly absorbed into the bloodstream.
The ability to absorb vitamin B12 decreases with age, leading to deficiency symptoms such as mood swings, muscle weakness, memory problems, impaired red blood cell production, and more. Vitamin B12 deficiency is often found in people that have digestive disorders such as Crohn’s disease or celiac disease, or have had gastrointestinal surgery in the past. Additionally, vegans and vegetarians that lack vitamin B12-enriched food products in their diet may be at greater risk for these nutrient deficiencies.
We recommend that you consult with a qualified 11:Eleven Medspa medical professional before receiving any Vitamin B12 treatment sessions. Our licensed medical staff administers the patient’s individualized dosage safely, along with topical anesthetic as needed. The supplemental vitamin B12 injection should take effect within 24 – 72 hours following treatment.

At 11:Eleven Medspa, we only use high-quality ingredients from Olympia Pharmaceuticals to deliver vitamins and minerals directly into the bloodstream, offering superior absorption versus oral supplements.
Olympia Pharmaceuticals is comprised of a state-of-the-art FDA 503B pharmaceutical outsourcing facility, and a 503A pharmacy. Both facilities provide access to a wide range of proven age management treatments, nutritional medications, IV therapies, vitamin injectables, and more.
Some of the most common symptoms include exhaustion and extreme fatigue, as well as brain fog or issues with memory. Additional indicators of vitamin B12 deficiency may include depression, headaches, gastrointestinal problems, muscle weakness, pale/yellow skin, loss of appetite, etc.
We advise scheduling an initial consultation with our medical team at 11:Eleven Medspa before receiving a vitamin B12 injection treatment. However, if you are experiencing symptoms of deficiency, have a diet that is low in foods containing B12, or have a digestive disorder of any kind, this treatment may be recommended for you.
The procedure is quick and simple, with the patient’s specific vitamin B12 dosage administered to the epidermis through the muscle (usually on the arm). If desired, our professional team can also use local anesthetic to numb the site of the injection for maximum patient comfort. After treatment, we advise that patients sit and wait a short time in our lobby to ensure any potential side effects have passed.
Although every patient reacts differently, some people may experience side effects around the area of the injection site, such as skin irritation, muscle ache, redness, mild swelling, or temporary dizziness.
Since the dose is delivered directly into the bloodstream, vitamin B12 injections start working within the first 24-72 hours following treatment. At 11:Eleven, we’ll customize a plan for you to ensure you receive the optimal amount of vitamin B12 treatments per month—and that they are always administered by a healthcare professional!
