The Function of Omega-3 Fatty Acids

Omega-3 fatty acids are essential nutrients involved in numerous functions and benefits to human health. More than 25,000 published articles indicate the health benefits of omega-3 from head to toe, including:

  • Cognitive development: Supports brain structure and neurotransmitter function across all life stages.
  • Vision enhancement: DHA is a primary structural component of the retina.
  • Cardiovascular protection: Helps regulate triglycerides, blood pressure, and arterial health.
  • Immune enhancement: Modulates inflammatory pathways and supports immune cell signaling.
  • Arthritis relief: EPA-derived mediators help resolve chronic inflammation in joints.

With the rise of veganism and vegetarianism, the global trend of over-fishing, and severe marine pollution, there is an emerging demand for fish oil omega-3 alternatives. Canchem Chemical provides a sustainable source of closed-system cultivated omega-3 from algae.

Is Fish Oil a Good Source of Omega-3?

For decades, fish oil has been advertised as beneficial to our health. However, due to the severity of marine pollution, we ought to reconsider whether the fish oil we consume is truly safe and free from contaminants.

The ocean has become a repository for industrial waste, plastic debris, and chemical run-off. These pollutants accumulate in marine organisms—and ultimately in the fish oil supplements consumers trust.

Four Major Sources of Marine Pollution

Factory discharge icon

Many factories discharge untreated wastewater containing heavy metals and polychlorinated biphenyls (PCBs) directly into the ocean.

Oil spills icon

Oil Spills

Pipeline breaks, sinking oil tankers, and faulty drilling operations cause severe, often irreversible damage to the marine ecosystem.

Marine debris icon

Marine Debris

Tons of plastic end up in the ocean each year, causing marine species to ingest and accumulate toxic pollutants into the food chain.

Wastewater discharge icon

Wastewater Discharge

Wastewater from households may contain hazardous substances and often ends up in the ocean untreated.

Bio-magnification: The Hidden Danger

In the food chain, toxic substances such as heavy metals, plasticizers, and PCBs are gradually accumulated within predators through water and food exposure. Because many toxic substances are easily ingested but difficult to excrete, they accumulate in the tissue of animals. The higher the trophic level in the food chain, the higher the concentration of toxic substances in their body. This process is known as bio-magnification.

Besides heavy metals, marine debris (plastic particles), oil spills, and inadequately treated discharge have worsened with industrialization. Due to this severe marine pollution, we ought to reconsider whether consuming fish oil long-term may impact our health—or the health of the next generation.

Toxin concentration increases at each trophic level of the marine food chain.

The DHA and EPA found in fish are not produced by fish themselves. They are bio-accumulated from primary producers—algae. Consuming algae directly bypasses the entire contaminated food chain.

Key Insight

Algae: The Original Source of DHA & EPA

The major source of omega-3 for human consumption has historically been fish, but fishes obtain omega-3 by consuming algae and bio-accumulating it through the food chain. Since bio-magnification of marine pollutants is a well-documented problem, the logical solution is to consume algae-derived omega-3 directly.

Algae oil is not only clean—it is also sustainable, suitable for vegans, and does not contain the major allergens associated with fish.

DHA and EPA originate from algae, not fish
Fish accumulate DHA & EPA by eating algae—algae oil goes straight to the source.

Algae Oil vs Fish Oil at a Glance

“Vegan Fish Oil” Must Come with DHA and EPA!

DHA and EPA are essential omega-3 fatty acids and are equally important in our diet. Nevertheless, most algae oil products on the market can only provide DHA, but not EPA.

EPA delivers several unique benefits that DHA alone cannot, including:

  • Lower heart disease risk: EPA helps reduce triglycerides and supports vascular function.
  • Enhanced immune response: EPA-derived eicosanoids modulate inflammation systemically.
  • Arthritis relief: Clinical studies link EPA to reduced joint pain and morning stiffness.

Without EPA, it cannot be a complete vegan fish oil. Now, Canchem Chemical offers a true vegan fish oil from algae—the first algae oil to deliver both DHA and EPA in a single product.
