Astaxanthin has been designated by the FDA as Generally Recognized as Safe (GRAS), which means you can be assured that the supplement will not be toxic to your body. Numerous studies have been conducted, with so far no reports of toxicity. Even though astaxanthin side effects are rare and minor, you should be aware of them, since there is still some chance you may experience them.
One of the most serious astaxanthin side effects is that it will lower your blood pressure. This is good if you have high blood pressure and are not treating it with medication or supplement. However, if you have high blood and are taking medication or supplements, then astaxanthin can cause the pressure to drop dangerously low. Also, if you are suffering from low blood pressure, you should be very careful about dosage, or not supplement with astaxanthin at all
Astaxanthin side effects also include hormonal changes. If you are taking hormone-altering medications you must be aware that they can interact negatively with astaxanthin. Astaxanthin can also interact with herbs such as black cohosh, vitex, and saw palmetto, which are commonly used to alter hormone levels in the body.
It can cause breast enlargement in men. Because of possible hormonal changes, pregnant and breastfeeding women should not take astaxanthin since there may be dangerous side effects to both the developing fetus and the mother.
If you are allergic to seafood such as shrimp and lobster, there is a possibility that what you are allergic to is the astaxanthin that they have consumed. If you have a known allergy to carotenoids, then you should not take astaxanthin.
It is best to consult your qualified healthcare practitioner in this case before starting a regimen of astaxanthin supplements. Dangerous allergic reactions include difficulty breathing and hives.
People with osteoporosis need to be very careful with this supplement because one of the unwanted astaxanthin side effects is lowered calcium levels in the blood. You want to consult with your healthcare practitioner before supplementing.
