Yes.

Generally, astaxanthin has side effects. The specific analysis is as follows:

Astaxanthin is a ketone carotenoid and a natural antioxidant. Astaxanthin has the effects of enhancing body metabolism, enhancing immunity, antioxidant, removing freckles and beautifying the skin. Astaxanthin is a very sensitive drug. Some people may develop allergies after using astaxanthin. This is its side effect. At the same time, using astaxanthin with carotene, lycopene, and antioxidants will reduce the absorption of nutrients.

In addition, when astaxanthin is used together with asthma drugs and antihistamine drugs, it will cause liver enzyme disorders, causing the drug ingredients to remain in the blood vessels, affecting the efficacy of the drug. Using astaxanthin together with antihypertensive drugs can cause blood pressure to drop too quickly, thus affecting the patient's health.

Astaxanthin has many side effects, so don’t overdose when taking it. I hope my answer will be helpful to you.
