How to Choose
When selecting a krill oil supplement, start by checking the EPA and DHA amounts per serving. Higher levels provide more robust cardiovascular and inflammatory support, but you may not need a very high dose if you already consume fish or other omega‑3 sources. Look for products that list astaxanthin content, as this antioxidant protects the oil from oxidation and adds eye‑health benefits.
Purity testing is another critical factor. Reputable brands publish third‑party certificates of analysis (COA) that confirm low levels of mercury, PCBs, and other contaminants. Finally, consider capsule size, coating, and any dietary restrictions such as gelatin or soy. A product that matches your budget while meeting these quality standards will give you the best value for your health goals.
