The benefits of omega-3 algae oil for kids

Omega-3 fatty acids play a crucial role in children’s development, particularly in growth, brain development, and vision. These special fatty acids are essential, meaning that the body cannot produce them itself and must obtain them through food.

That is why it is often recommended to give children oily fish once or twice a week, as it is rich in omega-3s. But what if your child does not like fish or you prefer a vegetarian or vegan diet?

This is where omega-3 algae oil comes in— a plant-based, sustainable oil from microalgae that provides the same valuable fatty acids as fish oil.

What is omega-3 algae oil?

Omega-3 algae oil is a purely plant-based oil typically obtained from the microalga Schizochytrium sp. and is an excellent source of bioactive omega-3 fatty acids—especially DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). What makes it special is that these two omega-3 fatty acids are the same ones we know from fish and are directly available to the body in bioactive form. DHA and EPA contribute to the normal function of the brain, vision, and heart.

In contrast, most other plant-based foods, such as flaxseeds or walnuts, provide the omega-3 fatty acid ALA (alpha-linolenic acid), a precursor that our bodies can convert into DHA and EPA only in small amounts.^1,2

To be precise, microalgae are the original source of omega-3s in the ocean. Fish accumulate DHA and EPA only when they feed on omega-3-rich algae. With algae oil, you can essentially skip the “detour” through fish and obtain omega-3s directly from their plant-based source. For families who avoid fish for ethical or environmental reasons (or for children who do not like fish), omega-3s from algae oil are therefore an ideal solution.

Algae oil supplements are generally available as liquid oil, drops, or filled into capsules and naturally have a marine taste, similar to fish and fish oils. To help children accept omega-3 products more readily, they are often enhanced with natural, delicious flavors such as orange, lemon, or berries.

Another advantage: algae oil is a sustainable source of omega-3. The algae are cultivated in controlled systems, and the oil is then extracted without placing a burden on marine fish stocks. This makes algae oil suitable not only for vegans but also better for the environment.

In addition, the algae oil is obtained under the purest conditions and is free from the pollutants that can be found in some fish oils (such as heavy metals like mercury or microplastics). In short: algae oil provides the same valuable fatty acids as fish, but on a plant-based and often purer foundation.

What science says about the effects of omega-3s in children

Omega-3 fatty acids – especially DHA and EPA – are known to play an important role in the development of children's brains and cognitive functions. This is also demonstrated by several high-quality studies:

Better learning and thinking

In a 2014 clinical study, 59 Mexican schoolchildren received omega-3 fatty acids daily for three months. The results showed that over 70% of the children improved in areas such as perception, attention, and sensory processing – important factors for school learning and concentration.³

Positive effects on ADHD and conspicuous behavior

Several studies show that omega-3 supplementation can have a supportive effect in children with ADHD – particularly with regard to attention, impulsivity, hyperactivity, and memory performance. Doses ranging from 123 mg to over 3,000 mg daily were investigated.^4,5,6,7

Support for skin health

Omega-3 fatty acids are a natural component of cell membranes and support the maintenance of a healthy skin barrier. They help retain moisture in skin cells and keep the skin supple. A good omega-3 supply can therefore contribute to healthy, smooth skin in children.⁸

It is important to note: Omega-3s are not a miracle cure and do not work overnight. Ensuring an adequate omega-3 supply lays the foundation for many bodily processes on which a child’s health can build.

So how can omega-3 algal oil specifically help with all this? By providing children with exactly what they often lack: high-quality DHA and EPA fatty acids. In the event of an insufficient supply, regular supplementation with omega-3 algal oil can meet the daily requirement and replenish stores. Especially when a child consumes few omega-3-rich foods such as fish, flaxseed, walnuts, or chia seeds, omega-3 algal oil can be a useful source of support.

Omega-3 algal oil vs. fish oil—what are the differences?

The good news first: According to current knowledge, they are absolutely equivalent! Omega-3 fatty acids from algae offer exactly the same health benefits as those from fish oil. After all, they are the same bioactive molecules (DHA and EPA). So, as far as their effects in the body are concerned, it makes no difference whether these fatty acids come from a fish or an alga—a child benefits from improved omega-3 intake in both cases.

Nevertheless, there are some practical differences between the two sources that may be important for you as a parent:

• Sustainability and origin: Fish oil is obtained from fatty fish (e.g., salmon, anchovies, or tuna). This requires enormous quantities of fish to be caught from the sea, which can put pressure on fish stocks, particularly as demand for omega-3s increases. Algal oil, on the other hand, is made from specially cultivated microalgae and is therefore significantly more sustainable.⁹ No fishing, no interference with marine ecosystems—a major advantage for anyone who cares about the environment and sustainability.
• Purity and contaminants: Although high-quality fish oils are purified, they may contain residues of environmental toxins from the sea (heavy metals such as mercury or microplastics), especially when the raw materials come from polluted waters. Algal oil offers a noticeable advantage here: The algae produced for dietary supplements are grown in closed, controlled containers, and the oil obtained is free from marine contaminants.⁹
• Taste and acceptance: Many people are familiar with the typical fishy taste or odor that can occur with omega-3 supplements—regardless of whether they come from fish oil or algae oil. Algae oil also naturally has a slightly marine flavor. To make the products more appealing to children, many manufacturers use flavor enhancement: Both fish oil and algae oil can be infused with natural flavors such as orange, lemon, or berries. This significantly improves acceptance, especially among children, and avoids the “Yuck, it tastes like fish!” reaction. There are now even special solutions for children, such as gummies or jellies.
• Nutrient profile: Both fish oil and algae oil provide DHA and EPA. One advantage of fish oil is its additional fat-soluble vitamins, such as vitamin D or vitamin A (for example, cod liver oil contains a lot of vitamin A), whereas algae oil usually provides only omega-3 fatty acids (sometimes with added vitamin D). In terms of omega-3 content itself, fish oil and algae oil are equally effective. Modern algae oils can often even have a higher concentration than fish oils.
• Availability and cost: Fish oil and fish oil capsules have been around for a long time and are relatively inexpensive to buy in drugstores. However, high-quality fish oils with low oxidation levels also come at a price. Algae oil products are still relatively new on the market and are somewhat more expensive due to their complex production process. However, they are becoming increasingly popular, which is gradually bringing prices down. For many families, the slightly higher price is justified by the advantages mentioned above (plant-based, pure, sustainable).

Conclusion: Is omega-3 algae oil the right choice for your child?

In summary, algae oil is an excellent option for providing children with essential omega-3 fatty acids, especially for families who prefer a plant-based alternative to fish oil. Through algae oil, your child receives the same important DHA and EPA fatty acids, which contribute to the healthy development of the brain, eyes, and vision. At the same time, you avoid potential disadvantages of fish oil, such as exposure to contaminants.

Whether algae oil is the right choice for your child depends primarily on your diet and your child's individual needs. If your child already regularly gets omega-3s through food—for example, by eating one or two portions of fatty fish per week—a supplement may not be necessary at all.

However, many children eat little fish or strictly refuse it, so an omega-3 supplement may be useful to cover the recommended daily amount. As a guide, nutrition experts recommend at least 250 - 500 mg EPA and DHA per day as a desirable intake for children and adolescents.^10,11,12

These amounts of DHA and EPA can be easily provided with omega-3 supplements. When buying, look for products that contain sufficient DHA and EPA per dose and are ideally tested for purity by independent laboratory analyses.

Especially for children, the dosage form is also very important: For younger children, child-friendly chewable gummies are often easier to take than large capsules. To mask the taste, innovative solutions designed specifically for children are now also available—for example, our delicious, sugar-free Omega-3 Gummies for Children with fruity flavor, which have no fishy taste and make taking them enjoyable.

If in doubt, discuss with your pediatrician or naturopath whether and which omega-3 supplement is suitable for your child—especially if other nutrients are already being supplemented.
