Formula and transparency
KeySlim Drops lists no complete ingredient list in our captured data. Vittaburn lists no complete ingredient list in our captured data. The two formulas do not share any named ingredients in our data. One side publishes no ingredient list at all, so the formula comparison is limited to the documented side; the missing list is a transparency gap, not a neutral tie. KeySlim Drops has 1 documented red flag: exaggerated-claims. Vittaburn has no documented red flags in our data. Ingredient order and blend totals are not the same as per-serving doses; without a Supplement Facts panel, part of the formula remains unknown. A longer ingredient list is not automatically a better formula; disclosure, dose and evidence quality matter more than the count.
