Complement vs Thorne
Thorne is the general premium play; Complement is the vegan-specific play with a tight, intentional lineup.
Complement built its brand around the nutrient gaps specific to plant-based diets: B12 (methylcobalamin), D3 (vegan-sourced), omega-3 (algae, not fish), zinc, K2, and a small vegan multivitamin. The lineup is short by design — five products covering what Complement argues are the critical vegan-diet gaps. Thorne has broader coverage and verification but requires you to assemble the vegan stack yourself from their larger catalog.

Full Thorne hub →When to pick Complement
Pick Thorne if you eat animal products and want a broad general supplement catalog with deep USP/NSF verification. The catalog breadth accommodates any dietary pattern.
When to pick Thorne
Pick Complement if you're vegan, vegetarian, or transitioning — and you want a curated 'these are the ones that matter' approach without having to research which B12 form, which D3 source, and which omega source works on a plant-based diet. Algae omega-3 vs fish oil is the standout differentiator.
Verdict
Thorne A (93, Most Verified) vs Complement B- (81). Thorne's overall score is higher, but Complement's vegan-specific focus adds value for that audience that a general Thorne stack doesn't replicate as cleanly.
