It has been dubbed the "world's healthiest tea" and now the Queensland company that put it on the shelves claims it has recreated its benefits in coffee.
Dr Red launched Spearole tea nine months ago and since then 16 million cups of it have been sold.
The blend of green tea, olive leaf, spearmint oil, grape skins and grape seeds has been tested on rats and results suggested the tea made them thinner, lowered blood pressure and improved their health.
Now, the company's Greg Jardine has developed Olevine coffee infused with those same anti-oxidants.
"It's the world's most consumed beverage and somebody has got to make this into a superstar. We intend to be the first," he says.
Scientists at the University of Queensland studied the effects of Spearole tea on rats.
Two groups were fed the same high fat, high carbohydrate diet while one of the groups was given Spearole tea.
But now the rats have become coffee drinkers and Associate Professor Lindsay Brown found the same results.
"We're measuring all the same parameters the only difference is they're having the coffee plus anti-ox in their diet rather than the tea and anti-ox in their diet," Lindsay says.
The rats given the tea lost abdominal fat, lost stiffness in their hearts, their blood glucose levels normalised and blood pressure was reduced.
"The weight difference between the two is about 50 to 60 grams which is about 10 percent of the body mass. It's showing the same results as with the tea," Lindsay says.
However, despite a following of happy Spearole tea-drinkers, the remarkable results shown in rats have not been documented on humans.
And endocrinologist Dr David Carey, who specialises in obesity, says the good news might be limited to the rat population.
"This is a good story if you're a rat out there," he says. But for humans?
"Yes there are some active ingredients. Yes it may slightly improve weight loss. Is it anything better than current available treatments? No," he says.
Olevine coffee will be available through Terry White pharmacies, and most major health food stores and pharmacies from next week.
