Vitamin B12 is essential for brain, nerve, and blood cell health. While everyone needs this vitamin, pregnant and nursing women require higher amounts. Vitamin B12 occurs naturally in foods like fish, seafood, liver, beef, and dairy, and is added to fortified foods such as cereals. At Baseline Tox Medspa, our B12 injections include a combination of B-vitamins—Thiamine, Riboflavin, Niacinamide, Pyridoxine, and Panthenol—to support skin health, alleviate anxiety and fatigue, boost energy, enhance mood, improve memory, and increase metabolism.

Administration

Vitamin B12 injections are usually administered intramuscularly in the thigh, upper arm, or hip. Dosage and frequency depend on the patient’s condition and needs.

Reasons for Vitamin B12 Injections

B12 injections may be prescribed for patients who are deficient or for those who may benefit from additional support for certain conditions.

Vitamin B12 Deficiencies

Deficiency can occur due to medications, gastrointestinal or autoimmune disorders, alcoholism, bariatric surgery, strict vegetarian diets, prolonged antacid or proton pump inhibitor use, or advanced age. Common causes include:

  • Pernicious anemia
  • Gastrointestinal disorders
  • Alcoholism

Conditions B12 May Prevent or Improve

  • Memory loss, Alzheimer’s disease, or dementia
  • Fatigue or lack of concentration
  • Weakened immune system
  • Heart, kidney, and liver disease
  • Infertility
  • Osteoporosis
  • Allergies or asthma
  • Tinnitus
  • Skin disorders
  • Lyme disease

While oral supplements or nasal gels are alternatives, injections are often necessary for patients with absorption issues.

Symptoms of Vitamin B12 Deficiency

Vitamin B12 deficiency may manifest as:

  • Anemia
  • Intestinal disorders and weight loss
  • Fatigue, weakness, lightheadedness
  • Memory loss or confusion
  • Depression or dementia
  • Rapid heartbeat and respiration
  • Mouth or tongue soreness or bleeding
  • Excessive bruising

Effectiveness

Injections are the most effective method of administering vitamin B12, as they bypass gastrointestinal absorption. While injections improve energy and quality of life for deficient patients, they do not enhance health in individuals with normal B12 levels.
