Algal oil is a type of oil that is derived from algae. It is commonly used as a source of omega-3 fatty acids, particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are important for overall health and cognitive function.
In protein powders, algal oil is often added as a source of plant-based omega-3 fatty acids. It is particularly popular in vegan protein powders, as it is a suitable alternative to fish oil, which is a common source of omega-3s in non-vegan protein powders.
In terms of safety, algal oil is generally considered safe for consumption by the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, individuals with seafood allergies should use caution when consuming it, as algae can contain similar allergens to seafood.
