I also look for a product that tells me the serving size and how many capsules or scoops I need to take each day.
Why I Choose This Combination

Price vs. Value
I do not always buy the cheapest option. Instead, I compare price with ingredient quality, dosage, and number of servings. A supplement may cost more but still be a better value if it provides a higher-quality formula and lasts longer.
Reading Reviews Carefully
I find customer reviews helpful, but I read them with care. I look for repeated comments about taste, effectiveness, and side effects. If many people mention the same issue, I take that seriously before buying.
