i listen to a podcast, i forgot who was talking. but he talked greatly about B12 methylated vitamin. I checkout the B12 that i was talking and it is not methylated. So I bought this, take one in the morning, and I felt something good. Even my wife who is always skeptical about supplement definately felt the difference. I think it lowered my wife blood pressure. Individual results vary. But it is not expensive so I think it is worth a try!

I had a severe B12 deficiency and the exhaustion was unbelievable. My Dr prescribed oral cyanocobalamin which was utterly useless, many people can't absorb it orally which they should've known since gastric reflux disease affects intrinsic factor that's essential for oral B12 absorption. During COVID Dr's in the UK stopped giving B12 injections to reduce footfall in the surgery and gave patients with deficiencies oral cyanocobalamin. I was so angry, the oral version had no effect on my levels. So I decided to deal with it myself and purchased sublingual methylcobalamin and started to feel better and see my levels start to increase.I decided to try this version due to the inclusion of adenosylcobalamin as well as methylcobalamin and wow, the mind-numbing, ...

Life Extension's B12 Elite has 2 highly bioavailable forms - adenosylcobalamin and methylcobalamin - to assure absorption and utilization. While adenosylcobalamin promotes the breakdown of fatty acids and amino acids while methylcobalamin promotes nervous system functions and red blood cell formation. Unfortunately I had to discontinue using it because the xylitol in it caused gastric upset. It's a top quality product and brand that's backed by significant research.

The brand Life Extension generally delivers when it comes to dietary supplements. This one is an exception, not because of quality (it does contain the most bio-available form of vitamin B12, namely methylcobalamin), but more because of personal preference: I would rather swallow a tasteless tablet than chew or dissolve in my mouth a flavored lozenge. However, the dosage of the active substance works quite well for me, as higher concentrations seem to give me acne breakouts. If only Life Extension could make the same product in tablet or capsule form...
I gave this Vitamin B12 a try because I'm pescatarian and don't get as much iron and B12 through food as meat eaters do. I actually don't like when vitamin supplements have super high dosages, like this small tablet which contains more than 20,000% of our daily requirement, but I gave it a try. I actually chose to swallow only half of it as the dosage was high. Quite frankly, I didn't notice any benefits on my energy levels or my hair so I'm not sure how I feel about this supplement. The ingredients and quality of Life extensions seems fine, but overall I can't say I noticed any benefits.

Good quality vitamin B12 from Life extension brand. Main ingredient is Methylcobalamin, which is natural version of this vitamin, so has good bio-availability. Good potency at 500mcg. Supports nervous system, energy and metabolism. Small size tablets under the tongue. Very good price/quality ratio on this brand, always pure ingredients without fillers. Thanks Iherb.
Vitamin B12 or cobalamin is a key element for many functions of the human body. We usually become aware of how important it is only when we feel the consequences of its lack. Our body cannot only synthesize it, but we have to take it in - through diet or nutritional supplements.Vitamin B12 is primarily found in meat, dairy products and eggs in food, but it is sensitive to high temperatures, which is why it remains in smaller quantities in thermally processed food.Vegetarians and vegans are primarily at risk of lacking this important vitamin, as well as anyone who consumes too little food rich in them or has an increased need for vitamins.
