Five formulas, each focused on one area

Microbiome Care is the daily foundation. Gut Restore, Calming Care, Itch & Immune Care and Metabolic Care each focus on one area of wellbeing. Every one is a powder with no chew binders and no artificial flavors or colors. The only other addition is a trace of what keeps the powder free-flowing.

Why a powder

More of every gram is active

A powder needs no chew binders or artificial flavors or colors. The only addition is a trace of what keeps it free-flowing.

Plentum powder sachet compared with a typical chew
Feature	Plentum powder sachet	A typical chew
Binders and fillers	None. A powder does not need them to hold a shape.	Usually needed to hold the shape and bulk of the chew.
Flavors, colors, flow	No artificial flavors or colors. Only a trace of what keeps the powder free-flowing.	Varies by brand. Check the other-ingredients list.
Actives per serving	More of each gram is active: up to 977 mg of actives in one 2 g sachet.	Actives share the serving with the chew matrix and flavor base.
Doses	Every dose in mg on the label, ingredient by ingredient.	Some labels list a blend total only.
Dosing by weight	One pre-measured 2 g sachet, 1 to 4 a day by weight.	Fixed piece sizes and counts.
How it is given	Mix into any food: dry, wet or a warm-water gravy.	Offered as a treat, or hidden in food.

This is a fair comparison with typical chews in general, not with any brand. A chew can be a good choice. Compare the label.

Stacking

Using more than one

Many dogs take Microbiome Care with a targeted formula. Here are the rules, and a check for repeated actives.

Start with one.Begin with the formula that matches your dog's main need. You can add a second later, once the first is part of the routine.
Count every sachet.Each formula is dosed by weight on its own, 1 to 4 sachets a day. Two formulas means two doses.
Check what repeats.A few actives appear in more than one formula, so doses add up. The check below shows which, and by how much.
No added-effect claims.Each formula stands on its own. We do not claim that using two together does more than the sum of what is on each label.
