Buying Guide: How to Shop Smart on iHerb (2025)

1) Look for quality markers.

• iTested Verified on iHerb-brand products means an independent third-party lab verified identity/quality—click the badge on the product page to view the report. (You’ll see this on California Gold Nutrition Omega-3.) iHerb
• Ingredient forms matter: chelated minerals such as Albion® TRAACS® for magnesium, or hydrolyzed collagen peptides for easier mixing. iHerb+1
• Certifications help: Informed Choice/NSF Gluten Free on collagen, certified vegan on electrolyte mixes, etc. iHerb+1

2) Prefer transparent labels.

• Choose products with clear ingredient forms, testing/certification callouts, and realistic claims. (Example: molecularly distilled omega-3 with cGMP manufacturing details.) iHerb

3) Packaging and stability.

• For probiotics, blister-packed and enteric-coated capsules can improve stability and delivery—handy when you can’t refrigerate. iHerb

4) Format & flavor fit.

• Powders (collagen, electrolytes) integrate into drinks; tablets/softgels keep routines simple. Match to your daily habits.
