One shoe does not fit all, therefore, while most may experience many Astaxanthin health benefits, some individuals may experience some negative side effects of Astaxanthin.
As with every product, do your homework and work under the supervision of a doctor.
The phytochemical astaxanthin is known for therapy for Parkinson’s Disease, strokes, Alzheimer’s Disease, high cholesterol, prevention of cancer and age-related macular degeneration. In its topical form, the substance is applied directly to the skin to relieve the pain, skin damage and inflammation of sunburn. Clearly there are many Astaxanthin health benefits. Although the substance is considered safe when consumed in supplement levels or when consumed in its natural form, there is not enough information about higher dosages to be certain about the effects over time and whether there may be astaxanthin side effects.
In its topical form, the studies are not conclusive or not available to determine the levels of concern. The difference between toxicity and lack of knowledge should be noted. As with any substance, knowledge continues to grow and expand. As more information is made available, there may be side effects linked to the substance that are currently unknown. Currently, the only signal that follows the ingestion of this substance is a minor orange tint that occurs when the pigment passes through the digestive system and shows up in the fecal matter.

For example, women who are breast feeding or who are pregnant should avoid taking supplements or using the substance topically. There is no documented danger, but avoiding anything which might be passed to the baby or to the fetus should be avoided. Since this is an antioxidant that passes the blood-brain barrier, it is best avoided.
People who have known allergies or who are hypersensitive to the substance or to carotenoids that are related, obviously should not use the products that include allergens. Other sensitivities could be those who are sensitive to algae, hormones or who have immune disorders.
[stextbox id=”info” color=”000000″ bgcolor=”f8f8a9″]The Code of Federal Regulations (CFR) has classified astaxanthin as Generally Recognized as Safe (GRAS). This designation allows it to be used as an additive to seafood. It is considered to be a useful antioxidant. As such, it can be used in the war against cardiovascular disease and cancer.[/stextbox]
There should be caution exercised when the person has parathyroid disorders. High blood pressure or hypertension is another condition where caution should be exercised. Osteoporosis is a condition that afflicts many women after menopause. Asthma and the substance could be a mixture that is unwise. Again, people are urged to be careful about choosing to take the substance.
Astaxanthin interactions are linked to medications for lowering cholesterol. Medications for parathyroid may not mix well with ingestion of astaxanthin. Women who are taking birth control medications should be cautious about the use of the nutrient at the same time. The same cautions apply to women taking medications to alleviate menopause symptoms. Finally, there may be an interaction of a negative nature when the individual is taking medications for asthma.
When and if there are any side effects of astaxanthin, they might be non-toxic, but they are still side effects. The person might show decreased blood pressure. The pigmentation of the skin may be increased. For some people, side effects might mean additional hair growth. Calcium levels in the blood may be decreased and there may be changes in the hormone balance. Some people have suggested that effects are experienced that are similar to some of the antihistamine medications. Other people report decreased libido.
Generally, side effects of astaxanthin are negligible as far as they are reported. Further study of the reactions may shed new light on the potential toxicity. Caution should always be exercised when pregnant or breastfeeding. When there is sensitivity to certain substances, that should be taken into account. When considering interactions, review the literature and always err on the side of caution. Remember to always speak to your health care professional about Astaxanthin side effects before doing anything.
