Professor Conner highlighted the association between vitamin C intake and improved mood, vitality, well-being, and lower depression, emphasizing that vitamin C deficiency is linked to higher depression and cognitive impairment. Despite existing research on these connections, there has been limited exploration into how quickly mood improvements occur with the introduction of vitamin C supplements or whole food sources.

Kiwi fruits are exceptionally rich in vitamin C and have three times the same amount of the vitamin of strawberries or oranges. They are a great source of vitamins E, K, folates, carotenoids, potassium, fiber, and other phytochemicals. Regular consumption of kiwifruit can be an effective strategy for health promotion and prevention of numerous diseases.

To address this gap, the researchers conducted an 8-week dietary intervention involving 155 adults with low vitamin C levels. Participants were assigned to daily intake of either a vitamin C supplement, placebo, or two kiwifruits. They reported their vitality, mood, flourishing, sleep quality, sleep quantity, and physical activity through smartphone surveys.

The results revealed that kiwifruit supplementation led to improvements in vitality and mood within four days, reaching a peak around days 14-16, and enhanced flourishing from day 14. In contrast, vitamin C marginally improved mood until day 12.
