I prioritize supplements with high-quality ingredients. I look for products that are free from unnecessary fillers, artificial colors, and preservatives. The more natural, the better for my body!
3. Formulation Type
DAO supplements come in various forms: capsules, tablets, or powders. Personally, I enjoy capsules for their convenience and ease of swallowing. However, I also consider my lifestyle and choose what fits best for me.
4. Brand Reputation
I always research the brands I’m considering. I look for reputable companies with good reviews and transparency regarding their manufacturing processes. A brand with third-party testing gives me peace of mind that what I’m taking is safe and effective.
