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!

Helps me feel better and they dissolve quickly.I keep these with me at work for whenever I start to feel anxious or tired and they help me to keep going.

Great Vitamin B12 Supplement

Working 16 hours days I need my energy to be able to focus especially in my field with dangerous ppl. Plus driving, use to be so hard because I was so tired. Now I feel balanced everyday day.

Not the best but not the worst. They taste like strawberries and don’t have a chalky flavor.

Their products are high quality and affordable.

Very good. Lack of vitamin b can really effect your health. These are mild flavor, good quality and work well.

To be honest, I don't notice any difference in my energy level when taking this supplement. Perhaps it takes time for my body to adjust to it....
