Product Information

Vitamin B12, in the forms of cyanocobalamin and hydroxycobalamin, can be administered parenterally as a prescription medication, usually by intramuscular injection [ 2]. Parenteral administration is typically used to treat vitamin B12 deficiency caused by pernicious anemia as well as other conditions (e.g., tropical sprue, pancreatic insufficiency) that result in vitamin B12 malabsorption and severe vitamin B12 deficiency [ 5].

However, a few observational studies have found no such association [ 88, 89]. In addition, according to a systematic review of 35 prospective cohort studies in 14,325 participants age 47 to 101 years followed for an average of 5.4 years, the evidence does not support a role for low vitamin B12 in the development of cognitive impairment or dementia [ 90]. So you might be wondering: how much vitamin B12 should I take daily? Health experts’ recommended daily allowances (RDAs) for B12 intake recommendations vary by age, but the recommendations are the same regardless of your sex [1]:Vitamin B12 is an essential nutrient that plays a critical role in several of your body’s processes. There are cases that people have severe vitamin B12 deficiency or can’t absorb vitamin B12 from oral supplements or food. Then, vitamin B12 injections may be the best solution. Vitamin B12 injections bypass potential barriers to the absorption of vitamin B12. [ 4] Pin Vitamin C ( ascorbic acid) can decrease the amount of vitamin B12 you absorb. Avoid taking large doses of vitamin C within one hour before or after taking this product. The following factors may put you at a higher risk of not getting enough vitamin B12 from diet alone ( 3, 6):

Your doctor may want to increase or decrease your dose of cyanocobalamin tablets depending on the level of vitamin B12 in your blood. What if I forget to take it? Though with limited evidence for satisfactory haematological and neurological responses in patients with vitamin B12 deficiency, both the studies have shown equal efficacy of oral and IM injections. The same is true if your blood work only shows signs of mild abnormalities: high levels of reticulocytes (immature red blood cells), homocysteine (an amino acid broken down by vitamin B12), or methylmalonic acid (MMA, a byproduct of amino acid breakdown) should subside after just a few vitamin B12 injection treatments. What to do if you suspect a B12 deficiency

But how long to recover from vitamin B12 deficiency after each treatment? The amount of time it takes for either treatment to take effect depends upon the severity of your B12 deficiency, and on the resulting health impacts of being deficient [4]. An elevated homocysteine level has been associated with an increased risk of CVD [ 72, 73]. Vitamin B12 and other B vitamins are involved in homocysteine metabolism, and researchers have hypothesized that supplementation with these micronutrients can reduce CVD risk by lowering homocysteine levels [ 72, 73]. If you have severe anemia, this medication may rarely cause low potassium levels in the blood ( hypokalemia) as your body makes new red blood cells. Tell your doctor right away if any of these serious side effects occur: muscle cramps, weakness, irregular heartbeat.
