Potency starts at the tree. SimplySours sources fresh leaves from heritage trees, some over 50 years old, selected by alkaloid testing, not picked at random. Mature trees plus a year-long ferment is the combination almost no one else replicates. It's leaf-only extraction, the way the tradition intended.
Purified & precisely dosed
Just as important as potency:
safety. Because this is a leaf-only, purified extract at a controlled dose, you get the benefits of the acetogenins without the annonacin overload linked to whole-fruit and seed preparations, the kind tied to concerns like atypical Parkinsonism. Strong enough to feel. Clean enough to take every day.
