The verdict
Micro Ingredients costs 84% less per 100 mg elemental than Nature Made: $0.06 vs $0.37. At one serving a day that is $21.90 a year instead of $135.05, $113.15 less.
Nature Made is listed by USP Verified. We didn't find Micro Ingredients in a testing program's database. If that listing matters to you, it is part of what the difference pays for.
The labels use different servings (Nature Made: 200 mg elemental, Micro Ingredients: 400 mg elemental), so both are priced on the same 100 mg elemental.
We compare price on the same dose. Taste, mixing, other ingredients and how a product suits you are yours to judge, so read both labels before you switch.
