DHA Supplements: Vegan and Vegetarian Sources

Are you a vegetarian or vegan who doesn’t like to eat fish-based foods? DHA (docosahexaenoic acid) is an essential nutrient for growing babies, children, and adults. However, vegetarian or vegan diets lack DHA sources

Some vegetarian diet advocates claim that vegans can consume enough DHA by eating plant-based omega-3 fatty acids, like flaxseeds and walnuts.

DHA is an omega-3 lipid that you normally consume through your diet, supplements, or both if your body doesn’t create enough of it. It may help prevent or treat chronic illnesses such as heart disease, tumors, Alzheimer’s disease, depression, and inflammatory disorders like rheumatoid arthritis.

DHA is crucial for a healthy and successful pregnancy and can lower the risk of premature birth. It also supports good brain and eye development in newborn babies and may help with ADHD symptoms in children. You should aim for 200–500 mg of DHA and EPA per day for optimal health.

DHA Supplements: Vegan and Vegetarian Ingredients

Even though DHA is widely available in fish-based foods such as eggs and fatty fish, people who follow a purely plant-based diet can obtain DHA through vegan-safe supplements.

Seaweed and Algae

Seaweed, nori, spirulina, and chlorella are all types of algae that many people consume for their health advantages. Seaweed and algae are essential sources of omega-3 fatty acids for vegetarians and vegans since they are one of the few plants that contain DHA.

The DHA level varies depending on the kind of algae and the product. There are several ways to include these items into one’s diet. For example:

  • Nori is a type seaweed that most people use to wrap sushi
  • Seaweed can be eaten as a crispy snack
  • Chlorella and spirulina are nutritious additions to smoothies and cereal

Algal Oil

Algal oil is a kind of oil derived from sea algae. Algal oil, like fish oil, is utilized as a source of omega-3 fatty acids. DHA is the most significant omega-3 fatty acid found in algal oil.

Algae oil is utilized in both food and medicine. Algal oil is most typically used in combination with other fatty acids to strengthen baby formula. It is also used to improve mental abilities in children and the elderly, decrease cholesterol, improve eyesight in persons with retinitis pigmentosa, and treat other conditions.

All vegan DHA supplements are produced from algae rather than fish or krill. While research on algae oil supplementation is limited, studies have shown that its bioavailability and consequent health effects are equivalent to those of fish-based DHA sources. It’s also a perfectly natural and original source of DHA. 

There are environmental benefits to using algal oil. Algal oil does not contribute to overfishing that disrupts oceanic food systems, causes global food insecurity, and damages coral reefs, all of which are associated with climate change.

Algae-based DHA supplements are a significantly more environmentally-friendly option than fish-based supplements.

Health Benefits of Vegan DHA Supplements

Your body makes a minimal amount of DHA from other fatty acids. That’s why you have to obtain it from food or supplementation. DHA and EPA can reduce inflammation and the risk of chronic diseases.  DHA promotes brain and eye health along with other health benefits.

Promotes Eye Health

DHA is an essential constituent of your eyes’ retinas. It may aid in the prevention of vision problems and other eye diseases that can lead to visual impairment and blindness. 

Reduces Heart Disease Risk Factors

DHA has been shown to minimize the risk factors for heart disease. Although it can’t completely eliminate the risk of having a heart attack or stroke, it can lessen the risk of chronic diseases and help you live a healthy life.

Treatment of Immune Disorders

DHA can help in the treatment of disorders such as diabetes, arthritis, ulcerative colitis, and psoriasis. Consuming enough DHA can help lower the risk of a variety of autoimmune disorders, including prediabetes, autoimmune diabetes, and sclerosis.

Improves Mental Health

People suffering from mental illnesses can benefit from DHA. It can help those with schizophrenia and bipolar disorder. DHA supplements reduce the frequency of mood swings and relapses.

Strengthens Bone Health

DHA can boost bone strength and joint health, possibly lowering your risk of osteoporosis and arthritis. Osteoporosis and arthritis are skeletal system disorders. DHA can increase bone strength by increasing the calcium content of your bones, which should lead to a lower possibility of osteoporosis.

Best Vegan DHA Supplements

Each capsule of a standard vegan supplement contains around 200 mg of DHA. If you’re going to supplement, it’s a good idea to take at least that much. Some of the most recent vegan products on the market include up to 500 mg of omega-3 fatty acids in each capsule.

While taking DHA supplements may provide some health advantages, it is still too early to recommend DHA as a therapy for any condition. DHA supplements should not be taken in place of standard chronic disease management medication. Avoiding or postponing treatment for a chronic condition in favor of self-treatment with DHA might have adverse health effects.
