Antioxidants: Resveratrol vs Astaxanthin


Antioxidants are fundamental for the health of the organism. They slow ageing down and improve general health, by countering the negative effects of free radicals so, which one to choose?

Free radicals are chemical elements which have lost one electron and are, as a result, very unstable. In order to stabilize, they steal that electron from other molecules around them, destabilizing the latter and creating more free radicals. This causes a chain reaction that affects our health negatively through our lives.

The origin of free radicals can be endogen, as a result of the normal activity of cells, or exogen. The latter takes place when the increase in the production of free radicals is caused by external factors like environmental or food pollution (pesticides, colourants, etc.), tobacco, alcohol, ultraviolet radiation or drugs.

The organism already has its own antioxidant defence like certain proteins or enzymes, but when it doesn’t have enough antioxidants to neutralize the excess of free radicals, then that’s the starting point of many chronic degenerative illnesses like certain types of cancer, dementia, cataract, diabetes, cardiovascular diseases, etc.

Among the substances with antioxidant power, two of the stand out: astaxanthin and resveratrol. But... Which one to choose? What is the difference?

ASTAXANTHIN

WHAT IS IT?

It is a natural red pigment known as a carotenoid. Its molecular structure is unique and grants astaxanthin exclusive properties. The structure allows the molecules to be inserted into the cell membrane and act simultaneously on free radical from the interior of cells and in the cell membrane itself. In addition, it is efficient in eliminating one of the most dangerous free radical for cells: singlet oxygen. 

BENEFITS

EYE HELATH Astaxanthin can pass through the retinal barrier, becoming an excellent eye protector against macular degeneration. Furthermore, it helps preventing some problems related to eyesight loss linked to ageing, cataract or glaucoma. It also contributes to reduce the eye fatigue caused by screens. 

SKINCARE Astaxanthin acts as a kind of natural sun screen, helping to reduce the damages caused by sun exposure. Also contributes to avoid sunspots in the skin, which are produced by oxidation processes. It promotes the production of collagen, which helps in keeping a firmer skin with improved elasticity and less wrinkles, as well as preventing their apparition.

COOL DOWN PHASE Astaxanthin has anti-inflammatory properties which help reduce muscle inflammation after an intense working out or after suffering an injury. If you some sport, you can take astaxanthin after working out to help the muscle recuperation process. In addition, it contributes to improve resistance and decrease fatigue. 

WHERE CAN IT BE FOUND?

  • Haematococcus pluvialis (green microalga from fresh water)
  • Salmon and trout
  • Shrimps

DID YOU KNOW...?

The antioxidant power of astaxanthin is 65 times higher than that of vitamin C and 14 times more powerful that vitamin E. 

RESVERATROL 

WHAT IS IT?

It is a polyphenolic compound produced by some plants as a defensive response against external attacks like ultraviolet radiation, fungi or some insects.

BENEFITS

CARDIOVASCULAR HEALTH It is a good ally to the heart, since it helps reducing inflammation of blood vessels and improves circulation. Also, it is demonstrated that it reduces bad cholesterol (LDL) and increases good cholesterol (HDL). 

ANTI-AGEIN Resveratrol is anti-ageing. Thanks to its ability to protect cells against oxidative damages, it is a good ally to slow cell ageing down. It is also linked to an improved cognitive function and to the protection of the brain against neurodegenerative diseases. 

ANTI-INFLAMMATORY Tanks to the anti-inflammatory properties, it helps prevent the apparition and symptoms of chronic illnesses arthritis or some autoimmune diseases.  

WHERE CAN IT BE FOUND?

  • Red grapes and red wine
  • Cranberries and blackberries
  • Peanuts

DID YOU KNOW...?

The interest on resveratrol took off while trying to explain the “French paradox”, which is about the low incidence of cardiovascular diseases in the French population despite following a high-fat diet (butter, meat...) and with a high consumption of wine.
