Despite the high temperatures of the sun, flamingos find their home in the marshes of tropical and sub-tropical areas around the world. Have you ever wondered how these birds resist such extreme conditions? What is your secret?

Their resistance is linked to their distinctive pink color, which they obtain thanks to a pigment called astaxanthin. This natural carotenoid is abundant in the algae and organisms present in the marshes, forming an essential part of the flamingo diet.

Astaxanthin and its Relationship with Flamingos

What is astaxanthin?

Astaxanthin is a red pigment present in shellfish and also in the feathers of flamingos and quails, among others. Its structure is similar to beta-carotene, but with some chemical differences that can make it safer. Astaxanthin has the unique ability to incorporate into cell membranes, interacting both intracellularly and extracellularly.

What are the benefits of astaxanthin?

1. Reduction of Oxidative Stress: Astaxanthin can reduce markers of oxidative stress, protecting cells from free radicals and contributing to cardiovascular health and anti-aging.

2. Skin Protection against UV Rays: Consuming astaxanthin can help protect the skin from ultraviolet damage, accumulating in the layers of the dermis and epidermis and blocking the penetration of UV rays.

3. Immune System Support: Astaxanthin influences the immune system, activating white blood cells (T cells and NK cells) to strengthen the body's natural defenses.

4. Reduction of Inflammation: In addition to stimulating the immune system, astaxanthin can help reduce inflammation, being beneficial in inflammatory diseases such as rheumatoid arthritis.

5. Supporting Cognitive Health: Carotenoids, including astaxanthin, may have positive effects on brain health, crossing the blood-brain barrier and providing protection for the brain.

6. Healthy Heart Function: Astaxanthin can help improve heart health by reducing LDL, or bad cholesterol, and increasing HDL, or good cholesterol.

Health Risks Related to Astaxanthin:

1. Interaction with Blood Pressure Medications: It can reduce blood pressure, so its consumption together with blood pressure medications should be evaluated by a health professional.

2. Pregnancy and Breastfeeding: The effects of astaxanthin in these stages are unknown, so caution is recommended.

3. Allergic Reactions: People with known allergies to shellfish should avoid astaxanthin from these sources.

4. Quantities and Dosage: There is no established dose, but caution and following health recommendations are suggested. The FDA-approved amount is up to 12 milligrams per day.

Finally, it is fascinating to observe how a diet rich in astaxanthin affects the color of flamingos' feathers, being an indicator of their health and well-being. This phenomenon reveals the close relationship between nature and health, highlighting the importance of astaxanthin in the lives of both these birds and the potential benefits for humans.
