Summary
This product features organic ingredients like seaweed and rosemary extract, which are beneficial due to their nutrient density and natural preservative qualities. However, the presence of organic sunflower oil, a seed oil high in omega-6 fatty acids, is a concern due to its potential to promote inflammation. Additionally, the product is moderately processed, which limits its score despite the clean ingredient list.
