Learn About C3G Restore
Black rice and blackberry extracts contain anthocyanins
The predominant anthocyanins in black rice are C3G (~91% of total) and peonidin-3-glucoside.

Hiemori et al., 2009
Cyanidin-3-O-glucoside accounts for ~94% of blackberry anthocyanins, dominating the blackberry anthocyanin fraction.

Anthocyanins help maintain muscle cell health
Across 20+ human trials with anthocyanin-rich foods, anthocyanins:
- Improved strength at all time points after exercise (g ≈ 0.45–0.67) .
- Improved power 24–48 h post-exercise
- Lowered creatine kinase (CK) and reduced DOMS at some time points
