Marine Algae Oil

Introducing our latest creation, our most sustainable superblend to date. It's a vegan blend of Omega 3’s offering a planet-friendly alternative to traditional fish oils. We’ve used sustainably sourced marine microalgae with natural, non-GMO plant based oils to create a formula that has lighter environmental footprint without compromising on effectiveness.

All the brain, skin, coat, and vitality support of marine omega-3s, without the fish. Blanca's Marine Algae Oil draws DHA directly from algae, the original source those nutrients come from in the ocean before they move through the marine food chain.

That makes it a clean, reliable option for pets with fish sensitivities, picky households, or pet parents who want a different way to deliver high-quality daily omega support. Instead of relying on fish oil, this formula goes straight to the source, offering a simple marine-based oil with a lighter footprint and a clear purpose.

DHA plays an important role in brain health, skin and coat condition, and everyday cellular function. For pets who need foundational daily support, algae oil offers a focused way to provide those nutrients without adding unnecessary complexity to the routine.

Active Ingredients:
Algae Oil, Hempseed Oil, and Astaxanthin

Inactive Ingredients:
None


We focus on using meaningful ingredients in purposeful amounts and presenting them clearly on the label. No unnecessary extras. No decorative claims. Just thoughtfully built formulas designed to do what they are intended to do.

16 oz / 96 tsp per bottle

Provide one teaspoon per every 25 pounds of body weight. Repeat up to twice daily.

Can be given during mealtime. For dogs not used to consuming oils, start slow and give half the recommended amount for the first 1-2 weeks.

The stability of the oil matters.

We start with small, wild-caught fish and handle the oil carefully to protect the fragile fatty acids that support skin, joints, and cellular health. By sourcing responsibly and bottling in controlled batches, we reduce variability and help maintain the intended composition over time. Quality is determined by how the oil is sourced, protected, and preserved from oxidation, not simply by the amount of omega-3 listed on the label.

Austin and Kat was built differently from the very beginning. We are employee owned, female founded, and still led by the same hands that shaped the company from day one. Every formula is made by our own team in our own facility, not handed off to outside manufacturers. The people who craft these products are the same people who bring them home to their own pets, which keeps our standards personal, consistent, and accountable in a way that cannot be outsourced.

Who Needs This Formula?

Especially good for environmentally conscious families and pets with fish sensitivities, formulated to help support skin, coat, and heart health through sustainable omega-3 nutrition. This plant-based formula benefits pets with fish allergies, families prioritizing environmental sustainability, and animals who need omega support without marine harvesting concerns. Ideal for pets who don't tolerate fish oils well, households with eco-conscious values, and animals requiring clean, stable omega supplementation. Perfect for supporting pets whose families want effective omega nutrition while maintaining environmental responsibility and avoiding potential fish-based allergens or sensitivities.

Science Behind The Scenes

This sustainable omega formulation represents cutting-edge nutritional science through direct marine microalgae sourcing that bypasses traditional fish oil limitations. Marine algae naturally produces EPA and DHA fatty acids that fish accumulate through the food chain, providing the same beneficial compounds with enhanced purity and stability. Astaxanthin from algae sources delivers powerful antioxidant protection that exceeds synthetic alternatives, while hempseed oil contributes complementary plant-based omega fatty acids. This 1,317mg per teaspoon formulation demonstrates that plant-based sources can provide equivalent omega-3 benefits to traditional fish oils while offering superior environmental sustainability and reduced contamination risk. The approach recognizes evolving nutritional science that prioritizes source purity and ecological responsibility without compromising therapeutic effectiveness.

FAQs About This Formula

There are 1,317 mg of Omega-3 fatty acids per teaspoon.

Just like fish oil, algae oil provides direct sources of DHA and EPA —Omega 3s that are crucial for comprehensive health benefits. Algae, as the base of the marine food chain, directly synthesizes these fatty acids, which are then accumulated by fish. By sourcing our Omega 3s directly from algae, we bypass the need for fish harvesting, significantly reducing our ecological footprint.

Algae oil is much like a plant-based oil in that it's more stable than fish oil and does not require refrigeration.

For optimal freshness, it's best to use the oil within 90 days of opening. While refrigeration is not required, storing your algae oil in a cool, dark place can help maintain its quality over time.

All of our formulas are made with love, 100% by us. We do everything in small batches at our own Seattle MAKERY, and unlike most companies, we source all our own ingredients from start to finish.

You bet! We spare no expense when it comes to quality assurance and our commitment to small batch manufacturing truly separates us from the pack.

We follow a strict set of criteria to ensure that every ingredient is top quality with consistent purity and potency, testing for impurities and contaminants at multiple points along the way. It takes extra time and effort as our process starts well before the day of manufacturing, but every step is well worth it and gives us the confidence that we are delivering our best.
