Most people know that omega-3s are important for heart, brain, and eye health. But here’s something you might not know: most fish don’t actually produce omega-3s — they get them from algae.

What are algae, exactly?

Algae are a diverse group of aquatic organisms capable of photosynthesis — using sunlight to create energy, much like plants. But unlike traditional plants, algae don’t have roots, stems, or leaves.¹

There are more than 40,000 known species of algae. Some are large and visible, like seaweed and kelp (called macroalgae). Others are too small for the naked eye and require a microscope to be seen — these are microalgae, and they’re where omega-3s begin.^1,2

Meet microalgae: nature’s omega-3 producer

Microalgae, also known as phytoplankton, are single-celled organisms that thrive in both freshwater and seawater.³ They’re incredibly nutrient-rich and are essential to marine life. They produce oxygen, serve as a food source for aquatic organisms, and play a foundational role in the ocean’s food chain.^1,2

Their standout role? Producing omega-3 fatty acids.

Microalgae are the primary producers of EPA and DHA — the same omega-3s found in fish.⁴ Fish obtain these fatty acids by consuming algae (directly or through smaller fish), which means when we eat fish, we’re actually getting omega-3s that originated from algae.

So why not go straight to the source?

Nature’s Way offer both high-quality fish oil and plant-based omega-3 options. The NutraVege formula is made from microalgae, the original source of the omega-3 fatty acids EPA and DHA. So if you’re looking for a clean, sustainable, and vegetarian-friendly alternative, you’re in the right place.

The algae used in this omega-3 is grown in a closed, controlled fermentation process — not harvested from the ocean — which means:

• High purity with fewer contaminants
• Freshness due to a faster manufacturing cycle compared to fish
• No impact on marine ecosystems⁶

It’s ideal for vegetarians, flexitarians, and those who prefer a fish-free option that still delivers on quality and efficacy.

More EPA — because it matters

The NutraVege formula has been recently enhanced to deliver twice as much EPA as before, now with the same ratio of EPA to DHA as most fish oils. EPA, along with DHA, helps support the maintenance of good health, cardiovascular health, and cognitive and brain function. NutraVege is available in both liquid and softgel formats, so you can get even more of what matters — in the way that works best for you.

Same beneficial nutrients. Just a different source.

Whether you prefer fish oil or plant-based omega-3s, the important thing is making sure your body gets plenty of EPA and DHA to support your health. Nature’s Way is proud to offer both — so you can choose the option that works best for you.
