Checked against public sources on July 26, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Ingredient amounts are hidden inside a blend A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.
The public sources did not settle the marketing promises on this label.
Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed.
Ingredient research can support context, but it is not a trial of this exact product.
This powerful powder blend thoughtfully combines nutritious greens & fruits and veggies with antioxidant vitamin C

We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 467 mg of prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 g a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
