First
This is my first time purchasing Life Extension Vitamin B12 (Methylcobalamin). I started taking it because I have anemia and wanted a gentle, high-quality B12 supplement. The lozenge is easy to take and has a mild taste. So far, I haven’t experienced any side effects, and it feels well tolerated. I chose this brand for its reputation and clean ingredients. I’m satisfied with my first purchase and will continue using it.

No more B12 deficiency!
After having B12 deficiency, I searched for a quality B12 supplement. Now, you may or may not know, Methylcobalamin is obviously a better choice than cyanocobalamin as its absorbed better. That is why I chose the Life Extension brand. The quality is superb and fast dissolving option is what I like. I feel like my nails and hair are also in much nicer shape now. Never settle for just cyanocobalamin. Get this B12 from Life Extension if you want to absorb your B12 easily. Such a great value for a premium product!

Good stuff!
I have to take B12 every day due to thyroid issues and this by far is my favorite. My labs have shown better results with the methylated B12 versus traditional naturemade B12 that I have always used and loved.

Boosted My Energy and Focus Naturally!
I started taking this Vitamin B12 because I was feeling sluggish and mentally foggy, and wow—what a difference! Within a week, I noticed more energy throughout the day and better concentration, especially during work and study sessions. No jitters, no crash—just a clean, steady boost. I also love that it’s easy on my stomach and dissolves quickly (if it’s the sublingual kind). The quality feels top-notch, and I’ve had zero side effects. If you’re feeling drained or just want extra support for your nervous system and mood, this B12 is a game-changer!
