Berry boost: blackcurrant supplement linked to big strength gains in Gym-Goers

This study looked at whether a supplement made from New Zealand blackcurrants could help people who do strength training lift more and think sharper. Twenty healthy adults who regularly lifted weights took either a low or high dose of the supplement, a placebo, or nothing for a week. Results showed that both doses increased how much weight they could lift and improved mental focus, with no side effects.
