Algae vs. Omega-3 vs. Fish Oil: What’s Really the Difference?

When it comes to supporting your dog’s joints, skin, and coat, omega-3s are a big deal. But not all omega-3s are created equal — and not all sources are right for every brand or every dog. You’ve probably seen “fish oil” listed on countless supplement tubs. At Onbord, we take a different route — we use algae oil, a cleaner, more sustainable source of omega-3s.

Here’s why that matters.

First, What Are Omega-3s?

Omega-3s are essential fatty acids — meaning dogs (and humans) can’t make them on their own. They need to come from food or supplements.

There are three main types you’ll see:

• ALA (alpha-linolenic acid) — found in plants like flax and chia.

• EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) — found mainly in marine sources such as fish or algae.

EPA and DHA are the real heroes here. They help manage inflammation, support mobility, and keep skin and coats looking healthy.

Fish Oil: The Traditional Source

Fish oil is the most common way to add EPA and DHA into a diet. It’s effective — but not perfect.

• Purity concerns: Fish can accumulate heavy metals and pollutants from the ocean. Even when purified, not every brand tests or filters to the same standard.

• Oxidation: Fish oil can spoil quickly, losing potency and developing that unmistakable “fishy” smell.

• Sustainability: Large-scale fishing contributes to overfishing and environmental stress.

So while fish oil works, it’s not always the cleanest, most ethical, or most stable option.

Algae Oil: The Smarter Source

Algae oil is where it all starts. Fish only contain omega-3s because they eat algae — so instead of taking it second-hand, we go straight to the source.

Algae oil provides the same essential EPA and DHA, without any of the drawbacks of fish oil:

• Cleaner: It’s grown in controlled environments — no ocean pollutants, no risk of contamination.

• Sustainable: It doesn’t deplete marine life or disrupt ecosystems.

• Plant-based: Perfect for dogs with sensitivities or owners looking for a more ethical choice.

• Fresh and stable: Because it’s not extracted from fish, it resists oxidation better and keeps its potency longer.

Why Onbord Chooses Algae Oil

We’re not interested in shortcuts — only smart choices that genuinely improve your dog’s wellbeing. That’s why every Onbord supplement uses algae-based omega-3s.

It gives your dog the same powerful benefits of fish oil:

• Softer, shinier coat

• Reduced inflammation and stiffness

• Healthier heart and brain function

…but with added benefits:

• No fishy smell

• No environmental compromise

• No unnecessary fillers

By sourcing our omega-3s from algae, we’re protecting the planet and giving your dog a purer, more potent supplement. It’s better for dogs, better for the ocean, and better for the long run.

The Bottom Line

If you’re comparing omega-3 sources, here’s the quick truth:

At Onbord, we choose algae oil because it delivers all the benefits of fish oil — without compromise.

Cleaner for your dog. Kinder to the planet. Just smarter science.
