Methylene Blue Oral Drops
For the dog that's slowing down a step. For the gray muzzle who still shows up every morning, tail going, ready anyway. A single measured blue drop — everyday cellular support, sized to your dog.
Methylene Blue oral drops, formulated for dogs. Pharmaceutical-grade (USP), 99%+ purity, dosed at 2 mg/mL — about 0.1 mg per drop — so you can match the amount to your dog's weight. Third-party tested and made in the USA. For dogs only.
Talk to your vet first. They know things about your pet that we never could — and the conversation matters more than the product. We'd rather you start later, with their blessing, than start sooner without it.

What is Methylene Blue?
Short answer: it's one of the oldest, most-studied compounds in medicine — used in human care for over a hundred years. At the cellular level it acts as an antioxidant and helps the mitochondria (the tiny engines inside your dog's cells) run more efficiently. Which is really just a scientific way of saying: it supports how cells make energy.
The honest version: the reason people are interested in methylene blue for animals comes down to three things — cellular energy, everyday antioxidant support, and the aging brain. Its safety profile in dogs at low doses is clean and well-documented, which is exactly why the amount per capsule is small.
What we're not going to do is tell you it's a miracle. The research is real and ongoing. The compound is real and well-characterized. What it does for your specific pet, on a specific day, is a conversation for you and your vet — not a sales pitch from us.

Inside the guide:
Nothing hidden. Nothing fudged.
You probably know which one is yours.
Not every pet needs the same thing. But most pet parents already have a feeling about where their dog or cat fits.
A small thing your pet does every day.
You give it
5–20 drops, sized to your dog's weight, once daily. Onto a bite of food or straight into the mouth.
It absorbs
Methylene blue is readily absorbed and circulates through the system — no special timing, no fuss.
It supports
At the cellular level, it's been studied for antioxidant activity and mitochondrial energy support. The quiet, background kind of support — not the overnight kind.
Small on purpose.
Sized to your dog.
Methylene blue is dosed by weight, and the amount is deliberately small. Start at the low end, give once daily with food, and don't go past the guide. The dropper is marked so you can be precise.
Your dog’s daily amount
5 Drops
0.5 mg
Start with 5 drops once daily with food. Use the marked dropper for accurate measuring.
Start low
Use the listed amount for your dog’s weight. For the first week, give once daily with food and watch how your dog responds. Do not increase beyond the guide unless directed by your veterinarian.
Before you begin
Shake well before each use and measure carefully with the supplied dropper. Review your dog’s medications and health conditions with your veterinarian before use. For dogs only. Stop use and contact your veterinarian if your dog has an unexpected reaction.

Will my dog actually take it?
Fair question. Some dogs swallow a capsule like a treat, while others need a little more convincing. The good news is there are a few simple ways to make it easier, from hiding it in a favourite snack to mixing it into a small amount of food and keeping the routine calm and consistent. Here’s what tends to work best:
Four easy options
Choose the method that works best for your dog.
On food
Shake well. Drip the drops onto a small bite of wet food, a lick mat, or a spoon of something they love. Mix and serve.
Straight in
Shake, tuck the dropper into the cheek pouch, and give slowly. Offer water after. Keep it calm — same time, same spot.
About the blue
it's real. Methylene blue can tint saliva, stool, or urine a blue-green shade for a little while. That's harmless and expected. One practical note — it stains (fabric, carpet, grout, countertops, hands). Aim carefully and wipe spills fast.
If your vet says no, please say no.
