Consuming a variety of colorful foods goes beyond just creating aesthetically pleasing meals for social media. Bright and vibrant foods contain a plethora of phytonutrients that offer numerous benefits to the body, primarily due to their antioxidant and anti-inflammatory properties. Among the many phytonutrients available, one stands out – astaxanthin.
Astaxanthin is a carotenoid, as explained by Lauren Manaker, MS, RDN, LD, the owner of Nutrition Now Counseling. Carotenoids are responsible for the vibrant colors found in foods like watermelon and tomatoes, ranging from red, orange, to yellow hues. Astaxanthin can be found in specific algae and naturally pink or red seafood such as salmon and shrimp. Interestingly, it is the compound responsible for the pink color of flamingos, derived from the algae, shrimp, and crustaceans they consume.
When it comes to foods rich in astaxanthin, while supplements are readily available, this antioxidant-like compound can also be naturally found in various sources, including salmon, rainbow trout, shrimp, crayfish, quail, microalgae, fungi, algae, yeast, krill, and sea bream.
Research on the benefits of astaxanthin has been ongoing for years, with studies focusing on its potential effects on eye, heart, immune, and gut health. Some key benefits of astaxanthin include its antioxidant properties, which contribute to overall wellness by addressing various health concerns. Additionally, astaxanthin has shown promise in supporting brain health, heart health, and may even enhance athletic performance based on studies conducted on both humans and animals.
Moreover, astaxanthin has been linked to improvements in vision, skin health, and immune function. Studies have demonstrated that astaxanthin supplementation could reduce eye strain, protect retinal cells, enhance skin moisture and elasticity, and reduce the appearance of wrinkles and age spots. While research on humans regarding immune health benefits is limited, studies on animals suggest that astaxanthin may boost immune function by increasing antibody production and natural killer cells.
In terms of side effects, astaxanthin is generally considered safe for consumption, especially when obtained from food sources. However, some individuals may experience red stool when taking it in supplement form. It is essential to be cautious if you have a seafood allergy or dietary restrictions and always check the supplement label for the source.
For those interested in trying astaxanthin supplements, several reputable brands offer high-quality products, including NOW Supplements, Jarrow Formulas, Sports Research, Pure Synergy, and Nutrex BioAstin. When selecting a supplement, consider factors such as production methods, company reputation, and product claims to ensure you are purchasing a reliable product.
In conclusion, astaxanthin is a powerful nutrient that can provide a range of health benefits, from supporting brain and heart health to improving vision, skin, and immune function. Incorporating astaxanthin-rich foods or supplements into your diet may offer a natural way to enhance overall well-being.
