Omega-3 dosing calculator.
Enter your pet's weight and goal. We turn the EPA and DHA figures into a daily amount of OmegaMax™, supply length and cost per day.
Maintenance follows the label serving bands by weight.
For a 10 kg pet on everyday maintenance.
Maintenance follows the OmegaMax™ label serving guide. Introduce slowly and build up over a few days.
Shop OmegaMax™Please note: this calculator works for NutriFlex® OmegaMax™ only. Do not use it to dose another brand. Every fish oil carries a different amount of EPA and DHA per pump or softgel, so the same number of pumps from another bottle will not give your pet the same amount of omega-3.

Where these numbers come from.
This calculator does not use a flat millilitres-per-kilogram rule. Targeted daily amounts are scaled to metabolic body weight, which is why a 5 kg dog needs proportionally more per kilogram than a 45 kg dog does. Most dosing charts skip this step, which is how small dogs end up underdosed and large dogs overdosed.
The coefficient depends on what you are supporting.
| Goal in the calculator | Coefficient (mg EPA + DHA per kg0.75 per day) |
|---|---|
| Skin and coat support | 125 |
| Joint and mobility support | 310 |
| Kidney support | 140 |
| Heart support | 115 |
| Safe upper limit, applied as a ceiling to every result | 370 |
Canine reference ranges from Bauer JE, “Therapeutic use of fish oils in companion animals,” Journal of the American Veterinary Medical Association, 2011;239(11):1441–1451, Table 1. The safe upper limit of 370 is given in the same table, drawn from the National Research Council’s Nutrient Requirements of Dogs and Cats (2006), which also sets a recommended allowance of 30 mg per kg0.75 per day for everyday intake.
Every result is capped. If a goal and weight combination would push the daily total past 370 mg per kg0.75, the calculator returns the capped figure rather than the uncapped one. Joint and kidney support are the two goals that reach the ceiling first, and Bauer footnotes both as amounts that may be increased towards that limit depending on severity.
Everyday maintenance works differently. It follows the OmegaMax™ label serving bands by weight rather than a coefficient, because maintenance is about steady daily intake rather than a targeted amount. For the reasoning behind both approaches, read how much omega-3 your dog needs.
A note on cats. The coefficients above are canine references. Feline data is scarcer, and there is no established safe upper limit for cats in the way there is for dogs. Targeted amounts for cats should be approached conservatively and built up slowly.
