Astaxanthin Side Effects: Allergies & Biological Functions
Studies show that antioxidants (such as alpha lipoic acid) can be a powerful tool for better health. Astaxanthin is a potent antioxidant derived from algae. Antioxidants aid in reducing the amount of oxidized LDL-cholesterol in the body. This type of cholesterol contributes to the formation of plaque buildup inside arteries. This process potentially leads to heart disease, blood clots, and strokes. Astaxanthin also help with certain gastro-intestinal ailments.

Even in the case of high doses, no known toxic astaxanthin side effects have been observed in humans or animals. Some people may notice a slight orange tint to fecal matter while taking astaxanthin. This is a harmless effect caused by small quantities of the pigment passing through the digestive system.
Although no effects have been encountered that reach a level of toxicity, this article will discuss:

Took Astaxzanthin ordered from Dr. Mercola. Within two days I had the most horrendous dizzy spells/vertigo I have ever experienced. Got off it immediately and recovered. I have some liver issues and I think my body could not handle it but they don’t warn you about that. And they should. BEWARE!
Hello:
I take medication for hypothyroidism, will this supplement interfere with the absorption of the meds? Is it safe to take with eltroxin? Also, I’m vegetarian,I do take krill, Vit D and CoQ10, would this be sufficient along with a very plant-based diet or would the Astaxanthin be enough on it’s own or in conjunction with these other supplements? Thank you
