THE IMMUNE GAP

Six windows where the gap opens. Check which one you're in.

Immunity isn't a fixed dial. It drops sometimes for just a few weeks, sometimes for months and in those windows, infections catch, weight stalls, and recovery slows. These are the six moments where that gap is widest

THE PET WHO'S ALWAYS A BIT OFF Runny nose. Watery eyes. Low energy. The pattern that keeps circling back week after week. Your pet is never "sick" they're just never quite right.
THE POST-WANING GAP (WEEKS 8–14) Mum's antibodies are fading. Your pet's own system isn't fully online yet. That 4–6 week window is where kennel cough, parvo and GI infections grab hold and where a daily immune habit makes the most difference.
FIRST 8–12 WEEKS AT HOME A new kitten or puppy is running on borrowed immunity. The first months are the most exposed, and one bad week can set them back weeks.
FRAIL, UNDERWEIGHT, OR STUCK Rescues that never gained the weight they should. Fussy eaters. Small breeds that are still "filling out" at two years. A body that's underweight is a body fighting with one hand tied.
BOUNCING BACK FROM ILLNESS After a GI bug, a respiratory flare, or a course of antibiotics, the immune system is depleted. Those two to three weeks are when you want to give their body every single advantage.
AFTER SURGERY Spay, neuter, dental extraction. The first 2–3 weeks ask a lot of a small body and a body that's healing can't afford an immune dip on top of it.
NOT ALL LACTOFERRIN IS THE SAME

We buy the 99% grade. Most of the shelf buys 70%.

Purity is the whole argument with lactoferrin. The higher the grade, the more intact active protein survives to do its job, and the less filler you are paying for by weight. We publish ours, and we have it verified by an independent lab.

WHAT IS IN EVERY CAPSULE

One capsule. Seven working ingredients.

No starch bulking, no flavour dust. Every gram in the bottle is there to do something.

Active Lactoferrin, 99% purity

The rare milk protein at the heart of the formula. It takes roughly 14,000g of raw milk to yield a single gram, which is why we refuse the cheaper 70% grade.

Bovine Colostrum IgG

The same class of immunoglobulins a newborn gets in that first golden feed, at 3,000mg per kg guaranteed.

Bacillus probiotic

Ten to the eleventh CFU per kg. Most of the immune system lives in the gut, so we feed it directly.

Taurine + L-lysine

Taurine, which cats cannot make enough of, supports heart and vision. L-theanine helps take the edge off stressful days.

Vitamins A, D3 & B3

The quiet workhorses behind skin, coat, bone and normal immune function.

Actually eaten

Chicken liver, fish meal and brewer's yeast make it palatable without a single artificial attractant.

HOW TO USE IT

Dosing by your pet's weight

Once a day. With dinner. That's the whole routine. Hand-feed it, or twist the capsule open over their food. No powder on the counter. No capsule in the sink.

Your pet's weightCapsules per day
Kittens & puppies (< 8 mo)2
Cats & small dogs — under 5 kg (11 lb)2
Medium dogs — 5–15 kg (11–33 lb)3
Large dogs — 15–30 kg (33–66 lb)3–4
Giant breeds — 30 kg+ (66 lb+)4

Every bottle holds 60 capsules, so a cat or small dog on two a day gets a full 30 days from one bottle. Kittens and puppies under 8 months: 2 capsules daily. During recovery your vet may suggest the higher end of the range. Most pet parents start with a 90-day supply. That's 3 bottles — which is why the 3rd one is free.

HOW TO READ A LACTOFERRIN LABEL

    Rocco is a beagle so he has always been food-obsessed but a bit lazy. I twist a capsule into his breakfast and by about week three he was dragging me around the park again. No fuss taking it, which with him is a small miracle.

    Started Sunny on it after a rough shedding season and a couple of ear infections. A month in, his coat looks glossy again and he is back to his goofy self on the couch every evening. Easy to add to his food.

    Winnie is nine and getting fussy, so I was skeptical. I open the capsule over her wet food and she eats it clean. She is more playful in the mornings than she has been in a while. It took a few weeks, but I am sticking with it.

    Baxter is eleven and watching him slow down was breaking my heart. I will not claim miracles, but since we started this he is steadier getting up and keen for his afternoon walk again. At his age, that is everything to me.

    We adopted Juno underweight and always a bit run-down. Our vet was happy for us to add immune support. She has filled out, her eyes are bright and she finally has the zoomies. I only wish I had found it sooner.

    Cheeto had the classic watery-eyes thing every few weeks. It did not vanish overnight, but the flare-ups are shorter and less frequent now, and he is more his chatty self. Only wish the bottle lasted a little longer.

30 Day promise

If your pet is not better off, we are not doing our job

Give Amicare a full 30 days. If you are not happy with how your cat or dog is doing, email us and we will make it right, refund or replacement, your call. Keep the bottle. Posting supplements back helps nobody.

BEFORE YOU ORDER

The questions we get most

Is it safe for both cats and dogs?

Yes. One formula, all life stages, both species. Dose by weight using the chart above. If your pet is pregnant, nursing, on medication or under veterinary care, check with your vet first.

How long before I see anything?

Nutritional support works on a slow clock. Most pet parents tell us the first noticeable change lands somewhere in weeks two to four, which is exactly why the 3-bottle offer is our most popular option. It carries the routine well past that mark without a gap.

How many capsules are in a bottle?

60 capsules, 250mg each. A cat or small dog on two a day gets a full 30 days from one bottle. Medium and large dogs take three to four a day and will work through a bottle faster, which is why most of them start on the Buy 2 Get 1 Free offer.

My cat spits out every pill. Now what?

Twist the capsule open and stir the powder through wet food or a spoon of broth. There are no artificial palatants in it, but the chicken liver and fish meal base means most pets take it without a fight.

What is lactoferrin, in plain English?

A protein found naturally in milk, most concentrated in that first feed a newborn gets. It is genuinely rare to extract: roughly 14,000g of raw milk yields a single gram. We use the 99% purity grade rather than the 70% grade common in the category.

Can this replace my vet?

No, and we would never suggest it. Amicare is a nutritional supplement that sits alongside veterinary care, not instead of it. If your pet is unwell, call your vet.

How fast does it ship?

Orders are picked and dispatched within 1–2 business days. US delivery usually lands 5–9 business days after that, and your tracking link is emailed the moment the parcel moves. Delivery outside the US varies by destination.

What if it does not suit my pet?

Email us inside 30 days and we will refund or replace it. Keep the bottle.
