We added a higher quality Vitamin B12 and it comes as methylcobalamin or adenosylcobalamin which are the forms of B12 naturally occurring in your body.
Methylcobalamin is your better choice if you are deficient in B12, or have the MTHFR genetic defect which reduces your ability to methylate this vitamin.
Vitamin B12 (Cobalamin) is one of 8 water-soluble B-vitamins that are absolutely vital to the highly optimized brain. And is essential to every cell in your body including your brain.
Vitamin B12 is known to enhance alertness, cognition, energy, vision, elevate mood, lower anxiety, and pain, and relieve insomniVitamin B12 as a nootropic can improve alertness, energy levels, boost attention span, concentration, intelligence, and memory. B12supplementation can help relieve stress, depression, insomnia and help balance your mood
Vitamin B12 has the coolest and most complex chemical structure of any nootropic. Vitamin B12 is called “Cobalamin” because it contains the rare earth element cobalt.
Vitamin B12 is absorbed in your intestines from food or a supplement using a process called intrinsic factor. The vitamin is then transferred to transcobalamin II (TC-II/B12 )which acts as a transporter.
Through a very complex process which I’m not going to try to explain here, B12 is converted into the active forms coenzyme 5′-deoxyadenosyl and methylcobalamin (MeB12).
Foods rich in Vitamin B12 include fish, shellfish, meat (especially liver), poultry, eggs, milk and milk products. The two best sources by far of B12 are clams and liver.
You cannot get adequate amounts of Vitamin B12 from plants. Vegetarians and vegans are especially in danger of B12 deficiency. Regardless of what food and supplement manufacturers say.
Plant foods contain analogs of B12 which are similar to, but not the same as, Vitamin B12. They bind to B12 r eceptors and block your intake of true B12.
Trying to get your Vitamin B12 from yeast products like Red Star Nutritional Yeast or Marmite is also problematic. These products do not naturally contain B12 but are fortified with it.
And Vitamin B12 is light sensitive. If stored in open bins or clear plastic bags or jars, B12 vaporizes and disappears.
Meat and animal products are your best source of natural Vitamin B12. But once again, relying solely on food for adequate B12 is difficult because it is destroyed during cooking.
You are much safer using a good Vitamin B12 supplement for your nootropic stack.
