Astaxanthin capsules
Astaxanthin is a natural carotenoid derived from the micro-alga Haematococcus pluvialis. The alga produces Astaxanthin to shield itself from harsh conditions such as intense UV light or drought. In the wild, this pigment is what tints salmon, shellfish and flamingos a vivid red. We work exclusively with natural Astaxanthin that retains the full carotenoid spectrum and contains zero synthetic additives. Production is sustainable and tightly controlled, ensuring purity and quality exactly as nature intended. EFFECTS Eyes Astaxanthin supports eye health on several fronts.

Omega-3 Algae Oil DHA 750 mg + EPA 250 mg
Contents and Use of Omega-3 Algae Oil Recommended intake:Take 21 drops daily with a meal. Can be taken directly or mixed with food. Contents:50 ml Ingredients:Algae oil (Schizochytrium), sunflower oil, natural tocopherol blend (vitamin E), rosemary extract, lemon oil Ingredients / 21 drops % NRV* Total omega-3 fatty acids 1000 mg *** DHA (docosahexaenoic acid) 750 mg *** EPA (eicosapentaenoic acid) 250 mg *** * nutrient reference value *** no reference available Omega-3 Algae Oil – Plant-Based Alternative to Fish Oil Our highly concentrated omega-3 oil from microalgae provides an especially pure and sustainable source of essential fatty acids, completely without fish. The microalgae used are cultivated under controlled conditions and deliver a high concentration of valuable marine omega-3 fatty acids. This creates a modern alternative to traditional fish oil that is both more environmentally friendly and exceptionally pure. Each serving provides 1000 mg of omega-3 fatty acids, including 750 mg DHA and 250 mg EPA. These fatty acids are among the most important nutrients for numerous bodily functions and are a key part of a balanced diet. By sourcing directly from algae, omega-3 fatty acids are obtained exactly where they naturally originate, in marine microorganisms. Fish only acquire these fatty acids through their diet. Algae oil therefore offers a particularly direct and sustainable source of these valuable nutrients. Benefits of Omega-3 Fatty Acids Omega-3 fatty acids are essential fats that must be obtained through the diet. In particular, the fatty acids DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) play an important role in numerous processes in the human body. Support for Brain and Nervous System DHA is a key component of cell membranes in the brain and contributes to normal brain function. Adequate intake of omega-3 fatty acids may therefore play an important role in concentration, mental performance, and cognitive processes. Cardiovascular Health EPA and DHA contribute to normal heart function. Omega-3 fatty acids are known to support fat metabolism and can contribute to a healthy cardiovascular system. Cell Protection and Inflammatory Balance Omega-3 fatty acids are components of many cell membranes in the body and help maintain cell stability and function. They also play an important role in the regulation of inflammatory processes and may contribute to immune system balance. Support for Eyes and Vision DHA is a natural component of the retina and contributes to the maintenance of normal vision. Adequate intake of high-quality omega-3 fatty acids is therefore an important part of a modern diet and can support brain, heart, and cellular health over the long term. Buy Omega-3 Algae Oil at Heilnatura Our omega-3 algae oil combines purity, sustainability, and high potency in a modern dietary supplement. Your benefits at a glance: 100% plant-based omega-3 source from microalgae 1000 mg omega-3 fatty acids per serving 750 mg DHA and 250 mg EPA Sustainable alternative to fish oil Free from fishy taste and marine contaminants Ideal for vegetarians and vegans Gently produced under controlled conditions Thanks to the high concentration of omega-3 fatty acids, even a small daily amount is sufficient to supply the body with these valuable nutrients. This makes our algae oil a modern and sustainable way to integrate omega-3 fatty acids into your daily diet, without any animal sources. Omega-3 – An Important Part of Modern Nutrition Many modern diets contain relatively low levels of omega-3 fatty acids, even though these essential fats play a central role in numerous bodily functions. Targeted supplementation can help improve daily intake and contribute to a more balanced nutrient supply over time. With our omega-3 algae oil, you choose a particularly pure, sustainable, and plant-based source of these important fatty acids. Why Omega-3 from Algae Instead of Fish Oil? Many traditional omega-3 products are derived from fish oil. However, the valuable omega-3 fatty acids do not originally come from fish themselves, but from the microalgae they consume in the ocean. Algae oil therefore provides a direct and particularly sustainable source of these fatty acids, without the need to go through fish. Extraction from cultivated microalgae enables controlled production with exceptionally high purity. At the same time, it avoids exposure to typical marine contaminants such as heavy metals or microplastics, which may be found in some fish oils. Another advantage: algae oil is completely plant-based, making it ideal for a vegan or vegetarian diet. Omega-3 from microalgae thus combines sustainability, purity, and a modern way of supplying essential fatty acids. Why DHA and EPA Are So Important The two omega-3 fatty acids DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) are among the most biologically active forms of omega-3s. While many plant-based sources only provide alpha-linolenic acid (ALA), algae oil delivers the directly usable forms DHA and EPA. These fatty acids are components of numerous cell membranes and play a role in various bodily functions. DHA contributes to normal brain function and helps maintain normal vision. EPA and DHA together contribute to normal heart function. The targeted combination of these fatty acids provides high-quality omega-3 nutrition that can support the body in multiple areas. Omega-3 in Modern Diets Many modern diets contain significantly more omega-6 fatty acids than omega-3s. This imbalance can affect various metabolic processes over time. Omega-3 fatty acids are therefore considered an important part of a balanced diet and are often supplemented to optimize daily intake. People who consume little fish or follow a vegetarian or vegan diet in particular often rely on plant-based omega-3 sources such as algae oil. Thanks to its high concentration, our algae oil allows for targeted omega-3 intake even in small amounts. This makes it easy and convenient to integrate omega-3 into everyday life as part of a conscious and modern nutritional approach.
