  • Purchase the Methyl B 12 – There are three different types of B 12 supplements. These are methylcobalamin, cyancobalamin and hydroxycobalamin. The last one, hydroxycobalamin, is rarely cofound on the market. When purchasing a B 12 supplement, you will want to purchase the Methyl B 12 or the methylcobalamin. It has been shown to absorb much better than the other forms of B 12. The cyancobalamin form is synthetic based and can cause a lot of problems when it comes to the absorption of the nutrient. It is important when taking supplements that you make sure they ARE being utilized by the body or they just pass right through doing no good whatsoever.
  • Look for sublingual, spray or liquid Forms – The benefit to finding these forms of the B 12 supplement is that the tablets or caplets don’t have to be digested before it is used by the body. Sprays, liquids and sublingual tablets go under the tongue where they can start being absorbed by the body instantly with no waiting.

With physician approval some people may need injections or shots of B 12 that are higher but this is usually done through the doctor for those who are suffering from unhealthy and extremely low levels of B 12. You don’t need to start off at a high dose. Start with a basic dosage of maybe 500-1000 mcg and see how you feel after a few weeks. This gives you a chance to see the effects. It also leaves you with some leeway to up the dosage since the commercial dosages can range up to 5000 mcg.
