Not All Antioxidants Are Created Equal – Astaxanthin, The Antioxidant Powerhouse

Life Sciences, Food, Food Ingredients & Innovations,
  • Wednesday, May 03, 2017

Antioxidants first came to the public’s attention in the 1990s, when researchers began to understand how free radical damage contributes to health problems. Fueled by new scientific findings and high consumer awareness, the antioxidant category rapidly developed and has remained strong and vibrant ever since – proof that ‘antioxidant’ is more than just a buzzword.

Antioxidants are not created equal. They come in a range of forms – vitamins C and E, manganese, selenium, astaxanthin, beta-carotene, lycopene, lutein, zeaxanthin, etc. Each with different effects on the body, recommended dosages and formulation considerations. With so many antioxidants available on the market, how do you pick the right one for your nutraceutical formulation?

Astaxanthin (pronounced “asta-ZAN-thin”) stands out as a valuable natural antioxidant for nutraceuticals due to its superb nutritional advantage. 6,000 times more powerful than vitamin C, and with the ability to cross the blood-brain and the blood-retinal barriers, astaxanthin is one of the most powerful antioxidants known. Its numerous health benefits are supported by extensive scientific research, including many clinical trials.

In this webinar, you will:

  • Gain insight into how antioxidants support health and well-being
  • Understand what makes astaxanthin a superior antioxidant
  • Learn how to select the best astaxanthin for your nutraceutical formulation

1. Why are antioxidants so important?

Modern life takes a toll on our body’s antioxidant defense system. Pollution, pesticides, stress, alcohol, unhealthy diet, lack of exercise, etc. — all contribute to the production of free radicals. Left uncontrolled, these unstable molecules can damage our cells and tissues, leading to many health problems. Antioxidants are our first line of defense against these harmful molecules. Acting as natural scavengers, they stabilize free radicals and help to keep their damage to a minimum. Gain insight into how antioxidants support health and well-being:

  • What are free radicals and how do they cause oxidative stress?
  • What are antioxidants and how do they work?
  • Why antioxidant supplementation is important?
  • What makes some antioxidants more effective than others?

2. What makes astaxanthin a superior antioxidant?

Astaxanthin is a naturally-occurring carotenoid produced by the microalgae Haematococcus pluvialis as a defense mechanism against harsh environmental conditions. For humans, astaxanthin is one of the most powerful natural antioxidants known, with applications in brain health, eye health, healthy aging, cardiovascular health, muscle endurance/recovery, and skin health. Gain insight into what makes astaxanthin an antioxidant powerhouse:

  • What is astaxanthin?
  • Why is astaxanthin superior to other antioxidants?
  • What are the health benefits of astaxanthin?
  • Is it difficult to formulate with astaxanthin?

3. How do you select the best astaxanthin for your nutraceutical formulation?

There are many factors to consider when choosing the right astaxanthin for your nutraceutical formulations — such as manufacturing source, contamination control, sustainability and quality certifications. Learn how to recognize a superior astaxanthin product:

  • How does the manufacturing source affect the product?
  • How does astaxanthin production affect the environment?
  • What contaminants should I be focusing on?
  • What are the possible contamination sources?
