After the green kiwi was the first fruit to receive a health claim in EU<\/a>, the sungold kiwifruit has recently been associated with a health effect, specifically on the skin.<\/span><\/span> Indeed, by directly measuring vitamin C in human skin, researchers have demonstrated that diet can increase the skin’s vitamin C content and influence its structure, while also revealing the limits of its effects on collagen formation and UV protection.<\/span><\/span><\/span><\/em><\/p>\n

In this new study published in the Journal of Investigative Dermatology, researchers directly examine how different skin compartments react to dietary ascorbate and whether these changes translate into measurable improvements in skin function.<\/span><\/span> The researchers also conducted a pilot dietary intervention based on kiwifruit, providing approximately 250 mg\/day of vitamin C, to test whether increasing plasma ascorbate levels raises the skin’s ascorbate content and alters skin function.<\/span><\/span><\/span><\/p>\n<\/div>\n
