Four Leaf Rover Protect

Per one-teaspoon serving, the label lists 5 billion CFU of Saccharomyces boulardii plus a 2 billion CFU "Probiotic Blend" of Bacillus subtilis and Bacillus coagulans, for 7 billion CFU total. Beyond the probiotic blend, the formula includes certified organic wild blueberry powder (1.85 g), bentonite clay (1.4 g), chlorella pyrenoidosa (200 mg), certified organic dandelion root powder (150 mg), certified organic burdock root powder (150 mg), and a humic and fulvic acid ingredient branded HumicSure (150 mg). No prebiotic ingredient is listed separately from the probiotic blend itself. The label doesn't state whether the 7 billion CFU figure is guaranteed through expiry or only at manufacture, and the product carries an NASC seal.

One detail worth a second look rather than smoothing over: the label describes this product as shelf-stable, "so you can keep Protect in your pantry," but the same brand's other Saccharomyces boulardii product reportedly prefers refrigeration. Two products with the same core organism from the same company, with different storage guidance, is the kind of thing we'd want double-checked against a physical label rather than assumed either way. Label claims include helping "detoxify from heavy metals & environmental toxins," maintaining gut health, and being "veterinarian formulated." Dosing scales across four weight brackets using fractional teaspoons, from a half teaspoon for dogs 1-30 lbs up to one and a half teaspoons for dogs over 90 lbs.
