Cold plunging has become a popular wellness practice for its ability to activate thermogenesis—the body’s natural heat-producing process that helps boost metabolism and burn fat. Interestingly, several scientific studies have shown that green tea extract can trigger a similar thermogenic response, but from the inside out.
Research published in journals such as the American Journal of Clinical Nutrition has reported that compounds in green tea, especially EGCG (epigallocatechin gallate) combined with naturally occurring caffeine, can modestly increase energy expenditure and fat oxidation through thermogenesis. In simpler terms, both cold exposure and green tea extract encourage the body to use stored fat as fuel—yet one does it through a shiver, and the other through a sip.

Several peer-reviewed studies have explored how key ingredients found in greenteaHAWAII may support overall skin health. Research on green tea extract—particularly its primary antioxidant compound EGCG (epigallocatechin gallate)—suggests it may help protect the skin from oxidative stress caused by UV exposure and environmental factors. In separate studies, noni fruit extract, including varieties identified as Polynesian noni (Morinda citrifolia), has been observed for its potential role in supporting collagen synthesis and maintaining skin elasticity due to its high antioxidant and phytonutrient profile.
While greenteaHAWAII makes no claims regarding these outcomes and has not been involved in the cited studies, we intentionally include these functional ingredients with awareness of their documented potential to support wellness from within.
