A company called Drink2Shrink (sometimes referred to as “Drink to Shrink”) has become surprisingly popular recently, so we wanted to publish a review of its ingredients to explain why we believe there is no evidence these products will cause weight loss.
In this article we’ll review the recipe of Drink2Shrink, explain why there’s no medical reason it should be effective, and offer some better science-backed alternatives.
Drink2Shrink is an herbal tea product with a blend of botanical ingredients.
The first listed ingredient is persimmon leaf. There is some research suggesting that persimmon extract (which is much more potent than the raw botanical material) may be effective for weight loss, but we haven’t seen any medical studies at all proving that persimmon tea aids with weight loss.
Holy thistle is the second ingredient and it’s a strange way to label what’s much more commonly referred to as milk thistle. We haven’t seen any research even testing this botanical in any form for weight management. It’s typically used to improve liver function.
In fact the only ingredient in this entire formulation with significant medical research backing its inclusion is ginger, which has been studied for weight loss. One medical study found that ginger supplementation decreased body weight. Another medical review found similar results: ginger was somewhat effective in supporting obesity management.
The doses of ginger one would get from Drink2Shrink tea is almost certainly lower than the average doses of ginger used in the medical studies linked above. Ginger is just one ingredient out of 9 in the tea.
We haven’t seen any medical research at all suggesting any of the other ingredients (malva leaf, marshmallow leaf, blessed thistle, papaya, chamomile, myrrh) are effective in supporting weight loss.
No Published Dosage
There is no published dosage of any of the listed ingredients on Drink2Shrink’s site. Since this is a product making specific health claims, this is unacceptable. Consumers can’t determine whether a product is safe and effective without dosage information.
As an example, if the company published the ginger dosage, we could compare it with the dosage of ginger used in the studies mentioned above on ginger and weight loss to determine if it’s an effective dose.
To be honest the whole brand comes across as so amateur that we wouldn’t be surprised if the owner doesn’t even know the dosage of each ingredient. It may just be a random blend of the selected herbs.
No Scientists Involved in Formulation
The Drink2Shrink website lists a woman named Sanya as the founder. She states that after successfully losing weight she wanted to help coach people to do the same.
That’s a nice mission but people with no scientific background at all generally can’t formulate effective products because they haven’t reviewed any of the scientific literature, which is definitely the case here given that nearly all of the ingredients make no sense for a weight loss formulation.
We recommend that consumers avoid health supplements that are made by people with no relevant health credentials. Since the health supplement market is very loosely regulated, taking products with no oversight puts your health in your own hands. We saw the same theme in our Soul Drops review: a founder who probably meant well but was selling products with absolutely zero published research behind them to unfortunate customers.
Better Weight Loss Alternatives
As we discussed in more detail in our review of Umzu supplements, increasing insoluble fiber intake is a medically proven (and cheap!) way to aid weight loss.
Insoluble fiber is found mostly in plant foods like beans, nuts and fruits with seeds.
When you consume higher amounts of insoluble fiber, you reach the feeling of “fullness” easier because the fiber contains no calories but occupies space in your stomach. It’s this effect that explains why it’s so much easier to eat 2,000 calories of McDonald’s in one sitting than 2,000 calories of beans and salad: the first meal has much less fiber.
We actually published a relatively critical review of this FDA-approved weight loss medication. While we still believe it’s a waste of money compared to dietary interventions like increased fiber intake, we believe it would be a better alternative to Drink2Shrink because it’s actually proven to be somewhat effective in medical research.
Plenity uses a patented fiber blend to increase satiation. The company funded a clinical trial proving it was superior to placebo in helping participants lose weight, but there may be some issues with the trial which we mentioned in the linked article.
