Benefits of B12 Shots
Vitamin B12 is essential for numerous bodily functions. Here's what adequate B12 levels support.
Energy Production
B12 is crucial for converting food into cellular energy. Low levels often cause fatigue and weakness.
Brain Function
Supports cognitive function, memory, and mental clarity. B12 deficiency can cause brain fog and mood changes.
Metabolism Support
Plays a key role in metabolizing fats and carbohydrates for energy production.
Red Blood Cell Formation
Essential for producing healthy red blood cells that carry oxygen throughout your body.
DNA Synthesis
Required for proper DNA replication and cell division—fundamental to all cellular health.
Nerve Health
Protects and maintains the myelin sheath that surrounds and insulates nerve fibers.
Who Benefits Most from B12 Shots?
While anyone can benefit from optimal B12 levels, certain groups are at higher risk for deficiency:
- Adults over 50 (reduced stomach acid affects absorption)
- Vegetarians and vegans (B12 is primarily in animal products)
- People with digestive conditions (Crohn's, celiac, gastritis)
- Those who've had gastric bypass surgery
- People taking metformin or acid-reducing medications
- Anyone experiencing unexplained fatigue or brain fog
- Athletes and active individuals needing enhanced recovery
- Those with symptoms of B12 deficiency

Frequently Asked Questions
Common questions about B12 shots at Highland Longevity.
B12 shots are beneficial for boosting energy levels, supporting metabolism, improving mental clarity and focus, enhancing mood, supporting red blood cell production, and addressing B12 deficiency. They're especially helpful for people with absorption issues, vegetarians/vegans, and those over 50.
Most patients benefit from weekly B12 shots initially, then transition to bi-weekly or monthly maintenance based on their response and lab values. Those with severe deficiency may need more frequent injections at first.
B12 injections bypass the digestive system entirely, delivering 100% of the vitamin directly to your bloodstream. Oral supplements require intrinsic factor for absorption, and many people (especially those over 50) have reduced absorption capacity. Injections ensure you receive the full dose.
Many patients notice increased energy within 24-48 hours of their first B12 shot. However, if you have a significant deficiency, it may take several weeks of regular injections to fully restore your levels and experience maximum benefits.
B12 supports energy production and metabolism, which can indirectly support weight loss efforts. While B12 alone isn't a weight loss treatment, adequate levels help ensure your body can efficiently convert food to energy. We also offer lipotropic shots that combine B12 with fat-burning compounds.
B12 shots are very safe with minimal side effects. Some patients experience mild soreness at the injection site. Because B12 is water-soluble, excess amounts are naturally excreted by the body, making toxicity extremely rare.
