It is normal for your Defend capsules to have slight color variations. Defend contains turmeric root extract, a nutrient that helps cleanse biofilm. Turmeric is a root, which means it grows underground, so this ingredient can have natural, seasonal variability which contributes to the color variation. Uqora products are made with safe, effective, high-quality ingredients, and the variation of capsule colors will not change your results with the products.
