Astaxanthin is proving to be one of the most powerful antioxidants available. It is several times more powerful than common ones such as vitamin A, beta carotene, and others. However, this has raised the question, “Astaxanthin dosage: How much do I need to get the health benefits?”. The answer is not completely clear because it depends on which health benefits you are looking for.

When it comes to the antioxidant effects of this substance, research indicates that a dosage of four milligrams per day is sufficient to exceed the benefits of several other popular antioxidants. The unique chemical structure of this nutrient creates a number of free electrons that can counteract the oxidizing effects of free radicals in the body.

This nutrient has also been shown to be a natural anti-inflammatory. However, it takes a slightly higher dose to maximize this effect. Eight milligrams per day has been shown to be effective at combating inflammatory conditions such as arthritis, tendonitis, and carpal tunnel syndrome. This is a great step forward in caring for patients suffering from these conditions that do not require a prescription because it is not a drug, but is a naturally occurring nutrient.


Athletes and others have found that taking high doses, twelve milligrams or more, increases their endurance and shortens recovery after intense workouts. They have also found that this nutrient accumulates in the body. For this reason, it is often recommended that athletes start out taking larger doses and decrease over a period of time.

Studies have shown that there are no toxic levels of this nutrient. However, Astaxanthin side effects have been noted with higher doses, including increases in skin pigmentation. This effect is not surprising as Astaxanthin is the substance that gives salmon its bright pink to red color.

This nutrient can be obtained from different sources. It is one component of krill oil, a dietary supplement that has been marketed for several years. However, the amount is extremely small in krill oil. For this reason, it is strongly recommended that one seek out a supplement composed of natural Astaxanthin that is produced from marine algae. This form is more potent than synthetically produced samples.

Some manufacturers recommend a dosage as low as two milligrams. While this amount will definitely benefit the body, studies have shown that optimum effectiveness is normally achieved with a dosage level between four and eight milligrams. For this reason, it would be wise to find a supplement that comes in increments of four milligrams in order to limit the number of capsules that must be consumed.

Another factor that can determine Astaxanthin dosage: how much do I need to get the health benefits is the nature of other supplements taken with it and diet. This is a lipid soluble nutrient, meaning that it dissolves in fats. One can maximize absorption to gain the same effectiveness from smaller doses by taking it with an oily supplement such as krill oil or Omega 3 fish oil. It will be necessary to consume higher quantities if there is no fatty substance available in which it can be dissolved.
