Best Uses for B12 Injections

Better nerve and muscle function
Vitamin B12 and folate are essential for producing methionine and S-adenosylmethionine (SAM). These methylation reactions are required to form the fatty myelin sheath around nerve cells that speeds up nerve conduction. They also play an important role in the production of brain messengers known as neurotransmitters.
Clearer cognitive function
High-dose vitamin B12 supplementation can lower high homocysteine levels in older adults both with and without cognitive impairment. After reviewing 21 clinical trials, researchers concluded that vitamin B supplements may delay cognitive impairment associated with aging. However, vitamin B supplements had no effect on information processing speed, episodic memory, or executive function. More research is needed to understand the relationship between homocysteine levels, vitamin B12 and cognitive function.
Lower risk of anemia
Vitamin B12 is required to produce healthy red blood cells. Vitamin B12 deficiency can result in malformed and large red blood cells, known as megaloblastic anemia. These large red blood cells cannot move efficiently from the bone marrow to the bloodstream, resulting in anemia. Anemia can lead to weakness and fatigue.
Improved mood
Vitamin B12 supplements may improve mood and ease depressive symptoms. In one study, approximately one in every three people with depression had elevated homocysteine levels. Supplementing with vitamin B12 lowers homocysteine levels and may improve mood, particularly in response to stress. In a review of studies, researchers found that while vitamin B12 supplementation did not improve depressive symptoms, low vitamin B12 levels were linked to an increased risk of developing depression.
Supports bone health
Vitamin B12 deficiency can increase bone fracture risk. When 1982 people who follow a vegan diet were tracked for 17.6 years and compared to non-vegetarians, they had a 43% increased risk of fractures, including hip fractures.

I have been working with Invigor Medical for several months, and find their service to be excellent. Today I was contacted by Courtney, who was checking in to see how things were going. She was very nice and helped me to save money on my semaglutide injections by switching to a 2 month subscription. Thank you Courtney! You were so kind and helpful.

Invigor's Commitment to Quality Medication

Our partner compounding pharmacies work with a registered and certified third-party lab to run quality control checks for every lot of compounded medications prescribed and delivered to our patients. These labs follow guidelines to ensure compounded medication safety and quality.
This test detects endotoxins (remnants of bacterial cell walls that can cause serious health problems) in pharmaceutical products. It helps ensure that medications are not contaminated by bacteria. Endotoxin limits are set based on how the medication is administered.
pH Test
This test measures the percent hydrogen (pH) or acidity or alkalinity of a product. The pH can affect the medication’s stability, solubility, and potency. To ensure the validity of the endotoxin test, the pH must be kept in a specified range.
Sterility Test
This test confirms that all sterile compounded medications are free from microbial contamination, including bacteria and fungi. Sterility testing reduces the risk of infections from taking medications.
Potency Test
This test measures the strength or the concentration of an active pharmaceutical ingredient (API) over time. It can be used in conjunction with stability testing to ensure that the medication will retain its potency until its beyond-use date.
