More About Vitamin B12 and Folic Acid:
Like other water-soluble vitamins, excess intake of Vitamin B12 is excreted and not stored in the body, which is why a continuous supply is needed. Zahler's B12 Energizer also includes folic acid, a B vitamin which supports brain health and is also crucial for healthy fetal development. Zahler B12 Energizer can be used long term or on an as-needed basis.

Ava ★★★★★ Sep 9, 2026

I was getting sluggish every afternoon around 2pm, and three weeks into this supplement that fog has mostly lifted. The dose of B12 and folic acid seems to be doing exactly what it says, and I've noticed I'm not reaching for that second coffee anymore.

The folic acid combined with the B12 makes this a solid pick for my morning routine—I noticed my afternoon slump disappeared within two weeks. The dose feels strong enough that I actually remember to take it daily.

Harper S. ★★★★★ Sep 3, 2026

I was skeptical at first, but after a few weeks of taking one tablet each morning, my afternoon slump is honestly gone. The solid dose of B12 plus folic acid feels like it’s actually doing something for my energy levels.
