what it is, what it is for and where to find it –

Astaxanthin is a reddish-pink carotenoid that is found naturally in fish and seafood, such as krill, seaweed, trout, salmon, shrimp and lobster, and which has potent antioxidant action, helping to fight free radicals and prevent the emergence of diseases such as cancer, atherosclerosis, diabetes and high blood pressure.

In addition, astaxanthin also increases the body’s protection against the sun’s ultraviolet rays, maintaining skin hydration and softness, and preventing the appearance of wrinkles and sagging. See other carotenoids that also help prevent wrinkles and sagging.

Astaxanthin can also be used in synthetic form, as an additive in aquaculture fish and seafood feeds. This dye can also be found at health food stores or pharmacies in the form of capsule supplements.

benefits of astaxanthin

Due to its potent antioxidant and anti-inflammatory action, astaxanthin provides several health benefits and can be used to:

1. Maintain skin health and softness

In addition, this carotenoid also prevents water loss, keeping the skin hydrated and smooth, and helping to prevent and fight wrinkles and sagging.

2. Prevent the emergence of cancer

As a powerful antioxidant, astaxanthin fights excess free radicals, preventing damage to healthy cells in the body and preventing the emergence of some types of cancer, such as breast, prostate and liver.

3. Preserve eye health

Astaxanthin helps to improve blood circulation in the retina, in addition to protecting eye cells from the sun’s UV rays and preserving eye health, helping to prevent conditions such as eye strain and glaucoma, an increase in eye pressure that can cause headache and difficulty seeing.

4. Lower LDL “bad” cholesterol

Astaxanthin is a dye with anti-inflammatory and antioxidant properties, preventing inflammation and oxidation of fat cells, and thus lowering the levels of bad cholesterol, LDL, in the blood. See other antioxidants that also help lower cholesterol.

5. Avoid neurodegenerative diseases

Astaxanthin has antioxidant, anti-inflammatory and anti-apoptotic properties, that is, preventing the death of healthy cells. Therefore, this carotenoid protects the cells of the nervous system, helping to prevent neurodegenerative diseases such as Alzheimer’s, dementia and Parkinson’s disease.

6. Strengthen the immune system

Astaxanthin helps to strengthen the immune system, because it increases the amount of T and B lymphocytes in the body, one of the body’s cells that help fight microorganisms, such as viruses and bacteria.

7. Prevent diabetes

Due to its potent antioxidant action, astaxanthin protects the cells of the pancreas against possible damage caused by free radicals, improving the functions of the hormone insulin and preventing insulin resistance and diabetes.

8. Avoid cardiovascular diseases

Astaxanthin contains antioxidant and anti-inflammatory properties, which help to lower cholesterol and triglyceride levels in the blood, preventing the formation of fatty plaques in the arteries and preventing the onset of diseases such as atherosclerosis, heart attack and stroke.

In addition, astaxanthin also preserves the elasticity of arteries, improving blood circulation and helping to control blood pressure.

Does astaxanthin make you lose weight?

Although astaxanthin helps lower blood cholesterol levels and prevent diabetes, this carotenoid does not have weight-loss properties.

To lose weight, it is recommended to maintain a balanced diet, prioritizing the intake of healthy and natural foods, such as fresh fruits and vegetables, whole grains, legumes and lean proteins, for example. See how to go on a weight loss diet.
