Vitamins are important for normal cell function, growth, and development, and are therefore frequently used to combat the onset of disease (particularly age-related diseases) and to extend healthspans (i.e., the healthy portion of a person’s life). Intramuscular injections are one of the most effective vitamin delivery mechanisms, and as is the case with any medication that is injected directly into patients’ blood streams, the quality of the manufacturing process and ingredients are of paramount importance. All of our injectable vitamins are manufactured pursuant to industry-leading standards, helping to ensure their safety and, we believe, efficacy.
