Customer Reviews (4.6 / 5 · 5 reviews)

Avery B. ★★★★★

These 500 mcg tablets are tiny and easy to swallow, which is a huge plus for me since I hate big pills. I notice a real difference in my energy levels by mid-afternoon now.

Sophia ★★★★★

I’ve been taking these B-12 tablets for about a month now, and they’re a solid 500 mcg dose that doesn’t upset my stomach. My energy levels feel more consistent throughout the afternoon, which was my main concern.

Ryan ★★★★★

My grandmother swears by getting B-12 from eggs and dairy, but I don't eat enough of either, so these 500 mcg tablets are my easy backup. They're cyanocobalamin, which is exactly what my doctor suggested, and I've noticed my afternoon energy slump isn't as brutal lately.
