Animal Essential Pet Enzymes & Probiotics

Bacillus coagulans) - 600 CFU/g⁷ (?)

(I have no idea what this means, are they trying to say there are 600 x 10⁷ )

For cats add 1/4 teaspoon to each cup of food daily.
For dogs add 1/4 teaspoon per 30 lbs. body weight, added to food daily

100 g, $16.29

 300 g $32.29

($0.1629 and $0.1076 per gram)

No gram weight for teaspoon given.

Using the equivalent of 1 T = 10 g, ½ t = 1.67 g.

= $0.27 or $0.18 for dog 60 lb. or more

Comment: As this product illustrates, most enzymes come from microorganisms. Many of those are also considered “probiotic”. Most sources of probiotic microorganisms, especially “fermentation products”, also contain many enzymes. Feeding a quality probiotic also provides these valuable enzymes. In short, they help digest the pet’s food. In short, saying “enzymes” and “probiotics” is redundant. Uses dried fermentation products which have a lower CFU than pure cultures.

Lactobacillus Sporogenes by Thorne Research

No guaranteed analysis

“Ingredients”

Lactobacillus Sporogenes (Bacillus coagulans) approximately 1.5 x 10⁹ CFU's

Cats & Dogs under 25 lbs - 1/3 - 1/2 capsule per day (open capsule and mix contents with food)
Dogs:
25- 50 lbs. - 1 capsule per day

$19.89/60 capsules

($0.3315/capsule)

60 lb. dog – 2 capsule/day = $0.66/day

Comments: Lactobacillus sporogenes’ main claim to fame is that it forms spores that allow it to withstand processing and transit through the stomach. The latter is not necessary because many Lactobacillus sp. Live IN the stomach, and prefer its acidic environment. Lactobacillus sp. Coat the inside of the stomach and provide a barrier to pathogens. Does not indicate whether pure or dried fermentation products used.
