Vitamin B12 Injections
At Vixen Aesthetics, we offer Vitamin B12 injections based on clinical presentation, without requiring a blood test. Many individuals experience symptoms of B12 deficiency despite having “normal” blood levels, and supplementation can provide significant benefits for energy levels, metabolism, and overall well-being.
Why Choose B12 Injections?
• Boosts energy and reduces fatigue
• Supports brain function and mental clarity
• Aids in red blood cell production and immune health
• Helps with metabolism and weight management
• Improves hair, skin, and nail health
Who Can Benefit?
Our B12 injections are suitable for those experiencing:
• Low energy or persistent fatigue
• Brain fog or difficulty concentrating
• Frequent colds or weakened immunity
• Tingling or numbness in hands and feet
• Hair thinning or brittle nails
• Vegan or vegetarian diets (which may lack sufficient B12)
Clinical Assessment & Ethical Considerations
Our approach is based on clinical presentation, meaning we assess symptoms and lifestyle factors before recommending B12 injections. However, we strongly advise patients to consult with their GP or request blood tests if they:
• Have ongoing unexplained symptoms
• Suspect an underlying medical condition
• Have a history of anemia or neurological symptoms
• Are pregnant or breastfeeding
What Happens if You Have a B12 Injection Without a Deficiency or Have Too Many?
Vitamin B12 is a water-soluble vitamin, meaning that excess amounts are usually excreted through urine rather than stored in the body. However, while B12 injections are generally safe, overuse or unnecessary supplementation can have some potential effects.
If You Are Not Deficient in B12:
1. No Significant Benefit – If your B12 levels are already sufficient, additional injections may not provide noticeable improvements in energy, mood, or cognitive function.
2. Placebo Effect – Some people may feel an initial boost, but this may be due to psychological expectations rather than an actual physiological need.
3. Masking Underlying Issues – If symptoms like fatigue, brain fog, or weakness persist despite normal B12 levels, there may be another underlying cause (e.g., thyroid issues, iron deficiency, or chronic fatigue syndrome).
If You Have Too Many B12 Injections:
While B12 toxicity is rare, excessive or frequent injections may cause:
• Mild Side Effects – Some individuals experience headaches, dizziness, nausea, or skin reactions at the injection site.
• Imbalance with Other Nutrients – High doses of B12 may interact with folate metabolism, potentially masking signs of other deficiencies such as folate or iron.
• Increased Anxiety or Restlessness – Some people are more sensitive to B12 and may experience jitteriness or difficulty sleeping if receiving too much.
• Interference with Lab Tests – High levels of B12 in the blood can interfere with certain lab tests, including liver function tests and markers of serious conditions like cancer or kidney disease, potentially leading to misdiagnosis.
How Often Should You Have B12 Injections?
The frequency of B12 injections depends on individual needs. Common recommendations include:
• Deficiency or clinical need: Weekly injections for 4–6 weeks, then maintenance every 1–3 months
• General wellness or energy boost: Monthly or as needed, based on professional guidance
• Long-term use: Regular monitoring to ensure appropriate levels and avoid unnecessary supplementation
Blood Test Recommendations
While B12 injections can be administered without prior testing, we recommend that patients undergo a blood test to check:
• Serum B12 levels
• Active B12 (holotranscobalamin)
• Folate and ferritin levels
• Homocysteine and methylmalonic acid (MMA) for a more in-depth analysis
If at any point a deficiency is suspected, we encourage patients to seek further medical evaluation to rule out underlying conditions such as pernicious anemia or malabsorption issues.
Legal & Ethical Disclaimer
At Vixen Aesthetics, we prioritise patient safety. Our services are not a substitute for medical diagnosis, and we recommend that all clients discuss ongoing symptoms with a healthcare provider. While B12 injections are generally safe, individual health factors should always be considered.
