The small changes you notice first.

An older dog resting in its bed at home
  • You come home. The hello happens from the bed now.
  • You call their name. Then again, a little louder.
  • They wait at the hinge side of the door.
  • They stop in the kitchen like they forgot why they came in.
  • You notice every small change now, and you worry about each one.

Hearing, eyesight and sore joints can change these moments too. If something changes suddenly, call your vet.

The little games still matter.

LIFE+ adds daily nutrition to their bowl, alongside the walks and games you share.

You hide the treat somewhere new.

IN THE STUDY · 2.8 YEARS: Dogs on the study diet kept learning when the correct choice changed. ↗

Dinner is still the highlight.

Stir LIFE+ into the food they already love. Beef liver and bone broth make it savory. No pill to hide and nothing to chew, so it suits a mouth with fewer teeth.

You’ve heard the seven-day promises.

We don’t make one. No published study tests the finished LIFE+ formula as a whole; the evidence is ingredient-level. So we publish every dose, link every study, and say what each one did not show.

  1. Week 1Watch that they finish the bowl. If they leave it, mix it into something they love.
  2. Week 2Full serving for their size. Watch their stools. If anything changes, slow down and tell us.
  3. Day 90Decide if it stays in the routine. If it doesn’t, we refund you.

Why these doses: vitamin E, vitamin C, L-carnitine and alpha-lipoic acid match, by weight, the daily amounts fed to a 22 lb dog in a 2.8-year aging study diet. One scoop holds the probiotic strain and daily dose from its own dog study.

Flavor base: beef liver and bone broth. No fillers, binders, artificial flavors, synthetic colorants, wheat, corn, or dairy. Made in the USA from US and globally sourced ingredients, in an FDA-registered cGMP facility.

IN THE STUDY · AGING BRAIN

Dogs on the study diet showed less oxidative brain damage.

The diet included antioxidants, mitochondrial cofactors and fruit/vegetable components. Behavioral enrichment was studied separately; neuron protection belonged to enrichment.

IN THE STUDY · 45 DAYS

Healthy dogs receiving the exact probiotic strain and dose showed lower oxidative-stress markers than their starting levels.

DE-CA9 · 1 billion CFU/day · 6 supplemented dogs, 4 placebo. Three blood markers fell from baseline; this did not establish three advantages over placebo. No main treatment effect; TBARS had a treatment-by-time interaction.

Before you decide

Will this fix what I’m seeing?

We can’t promise that, and nobody honestly can. LIFE+ is daily nutrition, not a treatment. Changes in an older dog can come from hearing, eyesight, joints or illness, so keep your vet in the loop.

How soon will I notice anything?

We don’t give a timeline. No study tests the finished formula. Give it a steady place in their daily routine, and use the 90 days to decide if it belongs there.

My dog is picky. Will they eat it?

It has a beef liver and bone broth base. Mix it into wet food or moistened kibble, and start with a little. If they won’t eat it, we refund you.

Their stomach is sensitive. Is that a problem?

Start with a small amount and build to the full serving over several days. If anything doesn’t sit right, stop and tell us.

Can they take it with their medication?

Ask your vet first, especially if your dog takes a blood thinner. Each scoop has 210 mg of vitamin E. Every dose is on the label, so your vet can check it in a minute.

Is it right for every breed?

LIFE+ contains beef liver. If your dog’s breed tends to store too much copper in the liver, such as Bedlington Terriers, Labradors, Dobermans, West Highland White Terriers or Dalmatians, ask your vet first.

Does it replace their senior food or other supplements?

No. LIFE+ goes on top of their usual food. If they already take other supplements, show your vet the labels side by side.

How much does my dog need?

Under 15 lb: ½ scoop. 15–30 lb: 1 scoop. 30–60 lb: 2 scoops. Over 60 lb: 3 scoops. One jar holds 60 scoops.

Can my cat have it too?

No. LIFE+ is made for dogs only.

When does it ship? Am I charged today?

Preorder opens once the manufacturer confirms the ship window. Nothing is charged until then.

The walk takes longer now. You go anyway.

LIFE+ is one small thing to add to the days you share.
