iHerb vs. Vitacost: Who Actually Has Cheaper Supplements?
We priced out a basket of 12 popular supplements on both sites, including shipping, to find the real winner for regular wellness shoppers.

We built an identical 12-item basket — vitamin D3, magnesium, omega-3, a multivitamin, and eight other common supplements — and checked out on both sites from a European and a US address.
US-based checkout
Vitacost's own-brand products undercut iHerb's equivalent name-brand items by roughly 12% on average within the US, with comparable shipping times.
European checkout
iHerb pulled ahead here — its EU distribution centers keep shipping costs and delivery times far more competitive than Vitacost, which ships internationally from the US with higher fees and customs delays.
Selection depth
iHerb carries a noticeably wider range of imported and specialty brands, which matters if you're shopping for a specific formulation rather than a generic equivalent.
Our verdict
US shoppers loyal to a specific ingredient list: check Vitacost's own brand first. European shoppers, or anyone wanting brand variety: iHerb wins on both price and delivery.
What we liked
- + iHerb ships internationally to more countries
- + Vitacost's own-brand line is notably cheaper than name brands
- + Both run frequent first-order discount codes
Where it falls short
- − iHerb's shipping cost rises sharply outside the US for smaller orders
- − Vitacost's selection of niche/imported brands is narrower
