Zera vs. Other Brands
Zera uses exclusively cold-pressed Ethiopian Nigella sativa — the highest natural source of thymoquinone in the world — so you actually get what's on the label.
Sourced From the Bale Mountains of Ethiopia
The high-altitude conditions of Ethiopia's Bale Mountains produce Nigella sativa with a significantly higher natural thymoquinone (TQ) concentration than seeds sourced from Egypt, India, or the Middle East. Every batch of ZERA is sourced exclusively from this region and cold-pressed below 100°F to preserve every milligram of TQ from harvest to softgel.
