Vitamin B12 – Your Questions Answered

Vitamin B12 is a crucial nutrient that plays a vital role in maintaining energy levels, supporting nerve cell health, and promoting overall wellness. It’s a key regulator in the body, ensuring essential processes like cell metabolism and red blood cell production function optimally.

Signs of B12 deficiency symptoms can include:

• Fatigue
• Pins and needles or numbness in the hands and feet
• Dizziness or faintness
• Heart palpitations
• Depression

These symptoms could also point to other health conditions, so a blood test may be recommended. REVIV offers consultations and blood tests to ensure the most appropriate treatment. 

Certain groups are more likely to experience B12 deficiency, including:

• Vegetarians and Vegans: Since B12 is primarily found in animal products, plant-based diets may not provide adequate amounts.
•  
• Individuals with Gastrointestinal Conditions: Conditions like Crohn’s Disease can impair B12 absorption.
•  
• People with Pernicious Anemia: This autoimmune condition prevents proper absorption of B12.
•  
• Those on Certain Medications: Proton pump inhibitors (PPIs) and other medications can interfere with B12 absorption.

Vitamin B12 is found mainly in meat, shellfish, fish, crustaceans, cheese, milk eggs and some fortified breakfast cereals. It can also be found in beetroot, potatoes, spinach, mushrooms and alfalfa.

Ideally everyone would get vitamin B12 from their food. It is an essential vitamin, and it is vital for the body and as it supports hundreds of vital reactions that occur. Many of us do maintain vitamin B12 levels through diet alone.

Dr Michael Barnish, Head of Life Science at REVIV Global, says: “Vitamin B12 deficiency is relatively common around the world because not everyone can get enough from their food. Those that need to increase their vitamin B12 level may not want to increase their red meat consumption due to other risks that are associated with this. Vegans and vegetarians consume low amounts and may need to consider supplementation, whether this be a daily oral version or an injection every month. 

Some people get enough Vitamin B12 from eating a balanced diet 

Dr Barnish adds: “For vitamin B12 to get into the blood stream, the stomach acid pH must be perfect, to activate an enzyme, called intrinsic factor, to take B12 into the blood stream. Therefore, those that drink alcohol regularly, smoke, have stomach protector medications or have poor diet, may have limited ability to get B12 into the bloodstream. Therefore, B12 from the food or from oral supplements may not reach the bloodstream successfully.”

Injectable vitamin B12 bypasses the gut and could help to bring the levels up to an acceptable range. At REVIV we explore nutritional needs with our customers and can check a person’s B12 levels we look at both the active and total circulatory levels to make a clear assessment.

REVIV offers two types of B12 vitamin booster shots:

1. Hydroxycobalamin: Naturally produced during digestion, this form converts to methylcobalamin in the body.
2. Methylcobalamin: The activated form of B12, ready for immediate use.

Most REVIV treatments, including intramuscular B12 therapy, do not require prior blood testing. Vitamin B12 is water-soluble, meaning any excess is safely flushed out by the body. However, we always conduct a detailed consultation to review your health history and ensure the therapy is safe and effective for you.

The effects of a Vitamin B12 Injection can vary depending on your body’s needs and unique genetic makeup. If you are significantly deficient, you may notice an immediate boost in energy and wellness. For others, the effects may take longer to manifest but can still provide long-term health benefits.

How does a B12 injection differ from oral supplements?

While oral supplements can be effective, a B12 injection bypasses the digestive system, ensuring maximum absorption directly into the bloodstream.

Is a B12 injection safe?

Yes. At REVIV, all B12 injections are administered by fully trained and registered medical professionals in a safe, regulated environment. We adhere to CQC (Care Quality Commission) standards for the highest level of safety and care.

Do I need a blood test before getting a B12 injection?

A blood test is not required before receiving a B12 injection. Since Vitamin B12 is water-soluble, any excess is naturally eliminated by the body. However, our team conducts a thorough consultation to ensure the treatment is right for you.

How quickly will I feel the effects of a B12 injection?

Results vary depending on individual needs, everyone is different. Some people notice an immediate boost in energy, while others experience gradual improvements in overall wellness over time.

How often should I get a B12 injection?

The frequency of B12 injections depends on your individual health and lifestyle. Many people opt for a monthly injection, while others may require them more or less frequently. Our experts will guide you based on your healthcare needs.

Can I get enough B12 from my diet alone?

Many people get sufficient B12 from animal-based foods like meat, fish, dairy, and eggs. However, factors such as age, digestive health, and lifestyle choices (such as a vegan diet) can affect B12 absorption, making B12 vitamin injections necessary for some individuals.
