Your questions answered
Still have questions?
MESSAGE USIs B12 injection more effective than oral tablets?
Injections offer superior bioavailability compared to oral supplements, as they bypass the digestive system and deliver B12 directly into the bloodstream to fuel your body. While oral supplements may be effective for some, the body’s ability to absorb them often decreases with age.
What are the side effects?
Vitamin B12 injections are generally safe, but some people may experience side effects, such as pain, redness, or swelling at the injection site, mild headaches, dizziness, nausea, or itching. Fatigue is also reported by some individuals after the injection. In rare cases, allergic reactions like difficulty breathing, swelling of the face or throat, or a fast heartbeat may occur. It’s important to consult with a healthcare provider before starting B12 injections, particularly if you have any underlying health conditions.
How often is B12 injected?
Treatment is typically started at 1ml/cc per injection once weekly. If you feel that you’re not getting the desired results, speak with your healthcare provider.
How do B12 injections help with longevity?
B12 shots are not only a fantastic way to boost energy, but they also enhance cognitive function, support vision health, and reduce the risk of age-related conditions like osteoporosis, macular degeneration, and cardiovascular disease. Additionally, B12 shots promote better sleep, and healthier skin, and nails, helping you look as good as you feel.
What are B12 injections used for?
Vitamin B12 is vital for several important bodily functions. It helps convert food into glucose, providing energy, and supports brain health by aiding in neurotransmitter production. B12 also plays a crucial role in maintaining the protective layer around nerves, promoting nerve health, and preventing anemia by supporting red blood cell production. Additionally, B12 works closely with folate (vitamin B9) in DNA and RNA synthesis, essential for the growth and function of all cells in the body.
How long does it take to see results from B12 injections?
Depending on the dosage, some individuals experience immediate and noticeable effects as soon as the B12 starts to infuse, feeling a sense of clarity and energy. For others, it may take a few weeks for the results to become evident.
Is B12 injection covered by insurance?
No, this product is not covered by insurance.
What are the storage requirements?
Store B12 injections in the refrigerator.
What is the cancellation and refund policy?
You can cancel the service at any time by sending an email to [email protected]. While we are unable to accept returns, we are committed to addressing any of your concerns.
Why should I use methylcobalamin over cyanocobalamin?
Cyanocobalamin contains a cyanide molecule instead of a methyl group, making it inactive and potentially harmful. While a small portion can be converted into active B12, it may replace the body’s natural stores with inactive B12. As a result, blood tests may show normal B12 levels, even though the body is not receiving the active form it needs.

Important safety information and common side effects
Vitamin B12 supplements are generally safe when taken at appropriate doses. The recommended daily intake for adults is 2.4 micrograms, but higher doses are also considered safe, as your body absorbs only what it needs, and any excess is passed through urine.
The most common side effect of B12 injections is discomfort at the injection site. If this occurs, try changing the injection location or reducing the frequency. B12 injections should be avoided during pregnancy, breastfeeding, or if you plan to become pregnant or breastfeed soon. High doses of B12, often used to treat deficiencies, may cause side effects such as headaches, nausea, diarrhea, fatigue or weakness, and tingling in the hands and feet.
