More than a dog supplement. A daily health foundation. 16 functional ingredients designed to support gut, joints, skin, immunity, brain and teeth.
You’ve tried the powders they won’t touch. The chews packed with fillers. The short-term fixes that don’t make a lasting difference.
MD1™ was designed as a simple, daily foundation – supporting your dog’s nutritional needs without adding complexity to your routine.
Supports a balanced microbiome and healthy digestion with clinically studied prebiotics, probiotics, and functional fibres. Designed to promote optimal stool quality, nutrient absorption, and long-term gut resilience.
Naturally sourced minerals and plant compounds to support healthy teeth, strong gums, and fresher breath. Helps keep plaque and tartar in check, supporting a cleaner mouth from the inside out.
A comprehensive blend of collagen, glucosamine, chondroitin, and omega-3s to help maintain cartilage integrity and joint flexibility. Formulated to support comfortable movement at every life stage.
Targeted nutrients that support mitochondrial function and efficient energy production. Helps maintain vitality, lean muscle function, and daily metabolic balance.
Rich in natural antioxidants and phytonutrients to help protect cells from oxidative stress. Supports immune resilience and overall systemic health.
Nourishing omega-3s, antioxidants, and phytonutrients to support a healthy skin barrier and vibrant coat. Helps reduce shedding, calm sensitivity, and promote a glossy coat from the inside out.
Nutrient-dense ingredients that provide broad, foundational support across digestion, mobility, and energy systems. Built as a daily base layer for long-term wellbeing.
One of the biggest challenges in pet health is consistency. Owners often end up juggling multiple supplements for joints, digestion, skin or dental care, which can quickly become difficult to maintain. What stands out about MD1 is how thoughtfully it simplifies that process into one easy daily routine without compromising on quality.

Many supplements fail because dogs won’t eat them consistently.
MD1™ was designed to be flexible by format – sprinkled as a topper when you’re in a hurry, or mixed with warm water to create a simple collagen broth. A daily moment your dog looks forward to, without changing how you feed them.
One daily serving is designed to cover key areas of your dog’s health – without needing multiple separate supplements

MD1™ (Marlo Daily) is a daily powder supplement for dogs containing 16 science-backed functional ingredients. It's designed to be the one daily essential your dog needs, covering gut health, joint support, immune function, dental health and longevity in a single scoop. Think of it as the daily foundation for your dog's health, not a targeted fix for one thing.
Soft chews contain up to 70% inactive ingredients: binders, fillers and palatability agents that leave very little room for what actually does something. Powder lets us hit functional doses across 16 ingredients without compromise. You get more of what works, none of what doesn't.
Where the clinical evidence supports it, yes. We formulate to the doses used in the studies that established each ingredient's efficacy, not the trace amounts that look good on a label but don't do much in practice. A small number of ingredients are included at levels supported by years of anecdotal use in veterinary nutrition rather than formal clinical trials. We're transparent about which is which on our ingredients page.
MD1™ is formulated for adult dogs. The feeding guide scales by weight up to a maximum of 4 scoops daily. If your dog has a specific health condition, is pregnant or is on medication, check with your vet first, as you would with any supplement.
In the UK, in partnership with one of the world's leading veterinary supplement manufacturers. Every formula goes through review by a team of veterinary nutritionists and formulation scientists before it gets made. For us that meant our ingredient choices, dosing rationale and quality standards being stress-tested by people who spend their careers in this field. EFSA-approved ingredients, UK-manufactured, no corners cut.
Mix one level scoop (4.5g) per 10kg of body weight into their food daily. It works as a dry topper or mix with a little warm water to make a gravy. Most dogs prefer the gravy method.
We recommend starting at half the recommended amount for the first week. This gives their gut time to settle, which is particularly relevant for dogs with sensitive stomachs. From day 8, move to the full serving.
It depends on your dog's weight. Our subscription pricing is structured to give you a monthly supply for your dog's size, so you're always getting the right amount at the right price.
Once opened, store in a cool, dry place or refrigerate to preserve freshness. Best used within 90 days of opening. We include a branded forever tin with first orders, made for exactly this purpose.
Yes. No minimum term, no cancellation fee. We'd rather earn your loyalty through results. Every first order also comes with a 90-day money back guarantee, so if you're not happy, neither are we.
The first 100 customers to pre-order become Founding Members and receive 25% off for their first three months. It's our way of recognising the people who backed us before the shelves were stocked.
We're in production now with first shipments expected on 1st June 2026. You won't be charged for the second month of your subscription until 1st July 2026.
Founding Member pricing is 25% off your first three months and it disappears once all 100 spots are taken. It won't come back at launch. Beyond the discount, this is a small founder-led brand built by dog owners for dog owners. The first 100 customers aren't just early buyers, they're the people who shape what Marlo becomes. That means direct access to us, genuine influence over where the brand goes, and being part of something from the very beginning rather than just another subscriber down the line.
MD1™ was created by Aaron Magnus-Moore, after failing to find a properly dosed daily supplement for his working line Golden Retriever, Marlo. The brand is named after him. The frustration was real and the product is the answer to it. The formula was developed in consultation with leading veterinary nutritionists and formulation scientists, so while the motivation was personal, the science behind it isn't.
Most pet supplements do one thing: joints, or gut, or coat. MD1™ is a daily comprehensive, the equivalent of replacing a shelf of single-benefit products with one scoop. The closest human equivalent is AG1. That category doesn't yet exist for dogs. We're building it.
Every ingredient is EFSA-approved, the product is manufactured in the UK and we publish the full ingredient list with exact dosages. No proprietary blends, no hidden quantities. If you want to cross-check the researcg behind any ingredient, we'll share the studies. Transparency isn't a marketing word for us; it's how we built the formula.
