Why 90 days? Guts change slowly. Stools often shift first, and skin and coat take longer, so we ask you to wait until day 90 to judge it.

Why fermented, in 20 seconds

The carrot test

1

Whole vegetables

Give a dog a chunk of raw carrot and you’ll find it in the yard the next day, barely changed. Dogs can’t break open plant cell walls on their own.

2

Two weeks of fermentation

Fermentation opens those walls first, and creates probiotics and postbiotics along the way.

3

Ready to absorb

That’s the whole idea behind Boost™: 18 whole foods, fermented together for two weeks and concentrated from 7½ lbs of ingredients in every bag.

Organic fermented superfood powder for dogs, shown in a scoop on a bed of the same textured, greenish-brown supplement.

What 90 days of fermented food does

Fermentation is the way.

Every day of the Reset, a teaspoon of fermented whole foods goes into the bowl. Fermentation has already done the hard work: it breaks down the plant cell walls dogs can't open on their own, and it creates probiotics and postbiotics along the way, with the fiber good bacteria feed on still in the food.

That's why it takes a season, not a weekend. Each day adds to the garden: the microbes get fed, the lining gets its building blocks, and more of every meal gets absorbed. By day 90 the change is in the dog, not just the bowl.

How fermentation works →

Why 90 days

Cell turnover takes time. So does a microbiome. Three things happen, in order, when you feed it every day.

  1. Days 1–30 · Detox

    Supports the body's natural detox pathways as the gut adjusts to fermented whole foods. Start low and go slow in week one, then feed the full dose every day.

  2. Days 30–60 · Inflammation

    Supports a healthy inflammatory response as the good microbes settle in. This is when many owners first notice the lawn, the coat or the energy.

  3. Days 60–90 · Integrity

    Supports the integrity of the gut lining as its tight junctions tighten. Judge the results here, not before. If you're not willing to give it 90 days, this product may not be right for you.

Owners who gave it 90 days

Every review comes from a verified buyer, in the owner's own words. Some reviewers received a reward for reviewing, and those reviews are marked. Boost used to be called Daily, so you'll see that name in older reviews.

Questions

90-day questions

Short answers, written by the people who make it. Still stuck? Ask us on the contact page.

How long does a bag last?

7.5 oz is 97 teaspoons; 3 oz is 39. At 1 teaspoon per 20 lb a day, a 7.5 oz bag lasts 97 days for a dog up to 20 lb, 48 days for 21–40 lb, 32 days for 41–60 lb, 24 days for 61–80 lb. The 90-Day Reset sizes the bags for you.

How much do I feed?

1 teaspoon per 20 lb of body weight, once a day, for every powder. Sustain™ is ½ teaspoon per 20 lb; Fiber & Fortifier™ is 1 teaspoon to 1 tablespoon per 20 lb, depending on how much fiber your dog needs. Mix it into food with a splash of water, never dry, and never cook it.

Why 90 days?

Cell turnover takes time. The microbiome shifts gradually, and nutrients need time to be absorbed before you can see the difference. Most dietary changes, for people too, need about 90 days to show. Feed it every day, without a break, then judge. If you're not willing to give it 90 days, this product may not be right for you.

Can I skip, swap or cancel my subscription?

Yes, anytime, from your account. Change the delivery date, swap products, change how often it comes, or cancel. There's no contract.

What is the 30-Day Taste Guarantee?

Returns are welcome for a 100% refund, including shipping, within 30 days of your first order, limited to one pack with at least 50% unused. That's the whole policy. If your first order has several packs, one is eligible, so we suggest starting with one. Fewer than 1% of dogs have ever needed it.

What happens after 90 days?

Move to Sustain™ for everyday maintenance, keep Youthful Grasses & Sprouts™ or Fiber & Fortifier™ alongside if you've added them, and bring Boost™ back once a year or whenever your dog needs a reset.
