The chocolate that gives vegans and vegetarians the B12 boost they've been missing
Are you tired of feeling tired? If you're plant-based, there's a 90% chance you're B12 deficient and it's stealing your energy, focus, and mood every single day.
Here's what B12 deficiency feels like:
That 3pm crash that makes you want to crawl back into bed
Forgetting words mid-sentence or struggling to concentrate
Feeling exhausted even after a full night's sleep
Your metabolism moving slower than molasse
3pm crash
Forgetting words
Exhausted even after sleep
Slow metabolism

The problem with most B12 supplements?
They're either giant pills that make you gag, chalky powders that taste awful, or they're so poorly absorbed that you're literally flushing money down the toilet.

The Delicious Solution That Actually Works
Imagine getting your daily B12 in two pieces of rich, fair-trade dark chocolate. No pills. No powders. No excuses.
Each bite delivers 250mcg of methylcobalamin – the most bioavailable form of B12 that your body actually uses (unlike the cheap cyanocobalamin in most supplements).
