Why B12?

What role does vitamin B12 play?

Without vitamin B12 the body has difficulty creating the red blood cells which carry oxygen and allow the brain and the nervous system to function properly. A deficiency in vitamin B12 can result in symptoms of chronic fatigue and lethargy. Evidence abounds of people combating the adverse of effects of such deficiencies with vitamin B12 supplementation. (Vitamin B12’s application in respect of chronic fatigue)



What medical conditions are treated with B12?

In addition to auto immune disorders there is strong evidence that vitamin B12 has been highly effective in the treatment of the symptoms of: anemia, ataxia, muscle weakness, rigid muscles, incontinence, low blood pressure, vision problems, dimentia, pyschosis and mood disturbances.

Other conditions such as alzheimers disease, angioplasty, breast cancer, canker sores, cardiovascular disease, cervical cancer, claudication, depression, diabetic neuropathy, prevention of fractures, high cholesterol, and joint (elbow pain) have been shown to have benefited from vitamin B12 supplementation under certain research conditions.

Why do vegetarians and vegans need B12 supplements?

B12 supplementation can be quite helpful for people who do not eat meat or animal products which are normally humans best sources of B12. This is especially true for vegans.

Why do athletes take vitamin B12?

Vitamin B12 is very popular amongst athletes who place heavy demands on their body for high performance. Even a small B-vitamin deficiency can result in reduced performance and recovery. Individual B-vitamin requirements vary and may depend upon the type and intensity of exercise, the amount of nutrients lost through sweat, and urine, and individual differences in diet. Those most at risk for the B-vitamin deficiencies include athletes who are limiting calories or have specialized, consistent or restricted eating plans.

Researchers at Oregon State University, published in the International Journal of Sport Nutrition and Exercise Metabolism, found that athletes who lack B-vitamins have reduced high-intensity exercise performance and are less able to repair damaged muscles or build muscle mass than their peers who eat a diet rich with B-vitamins.

Additionally, the heightened sense of well being that can result from supplementation has been reported anecdotally to contribute to increased motivation and drive which leads to better performance. Athletes that feel good perform better.

Quality & Safety

Is your vitamin B12 high quality?

Yes. B12 Direct works only with government licensed laboratories. Our primary supplier has been manufacturing vitamins since 1969 and certified Good Manufacturing Practice (GMP, World Health Organisation) by Thai Food and Drug Administration.

Further we have have independently tested our vitamin B12 for quality and safety at Mérieux NutriSciences (Silliker, Vancouver CA). Our testing covers potency and common contaminants.

How do I inject safely?

Any treatment with injectable vitamin B12 should be done under a doctor’s supervision. The initiation, administration and discontinuation of use of vitamin supplements should be under the guidance of a treating physician. Proper injection requires guidance and experience. Injections should be performed under the supervision of a doctor or medical professional.

While we don’t advise that people self inject these vitamin supplements themselves we offer a safe injection protocol for intramuscular injection as follows:

  1. Swab the top of the vial with isopropyl alcohol
  2. Insert the needle of a 21-24 gauge syringe into the vial and pull out the desired measure of injectable vitamin as per your Dr.’s prescription (generally .5CC-1.0CC
  3. Insert the needle into one of the areas of the body without arteries and few large veins IE. the buttocks (glutimus maximus), the shoulder muscle (deltoids) or the front of the quadriceps large (rectus femoris) muscle of the leg.
  4. *Before you inject the contents of the syringe into the location you’ve selected make absolutely sure you have not inserted the needle into a vein by pulling the plunger back. If you draw any blood whatsoever into the syringe then withdraw the needle immediately and pick another location.
  5. Once you’ve determined that your injection site is safe and that the contents of the syringe will be injected into a muscle only, then slowly depress the plunger of the syringe until all of the syringes contents are safely inside the muscle tissue.
  6. Slowly withdraw the syringe.
  7. Swab the injections site with alcohol.
  8. Put the cap back on the used syringe and dispose of it in a safe manner.

How do I handle and use ampules?

Ampules are small single use vials. They are designed to be broken at the narrow point in the neck. Most have been weakened to make this easier and mark the weak point with a printed line.

Opening an ampule:

  1. To help keep the ampule and medicine as sterile as possible, use some sanitizer gel on your hands, or wash your hands thoroughly.
  2. Hold the ampule upright and tap the top to remove solution from the head space.
  3. Swab the neck of the ampule with an alcohol pad.
  4. Wrap the neck with an alcohol pad or gauze, and grasp the top with the thumb and index finger of one hand. With the other hand, grasp the bottom of the ampule.
  5. Quickly snap the ampule moving your hands away and out from you. If the ampule does not snap easily, rotate it slightly and try again. A light pressure should cleanly
    snap the ampule open, while using too much force can cause it to shatter.
  6. Inspect the opened ampule for any particles of glass that might have fallen inside.

If the glass shatters when you open your ampule, wrap all the pieces in a tissue and discard. Don’t use the medicine if your ampule shatters.

Transferring the solution from the opened ampule:

  1. Hold the ampule at about a 20-degree down angle.
  2. Insert a needle/straw into the ampule taking care not to touch the ampule neck where it is broken.
  3. Position the needle in the shoulder area of the ampule beveled edge down. This will avoid pulling glass particles into the syringe.
  4. Withdraw solution but keep needle submerged to avoid withdrawing air into the syringe.
  5. Withdraw needle from ampule and remove all air bubbles from the syringe.
  6. Transfer the solution to the final container using a filter needle or membrane filter.

How do I contact US Postal Service by phone?

If the online tracking does not provide the answers you need you may be able to learn more by phoning USPS. Be prepared for a long wait on hold.

We find the best option to choose in the main voice menu is the 4th option, “carrier”. From this option you can provide your tracking number and speak to an agent.

Some tips:

  • the first menu item “package” only provides access to tracking information and not access to a live postal agent
  • answering “agent” (repeatedly) when asked for a piece of information, even when this is not what the voice system wants, can sometimes get you through to a postal agent
