Compared with Nature Made Vitamin C 500 mg Tablets.

What a 90-count bottle actually buys

Ninety Ester-C tablets represent forty-five complete servings because the label groups two 500 mg tablets together. Nature Made reports one 500 mg tablet as a serving, so its 100-count bottle has 100 servings. These totals describe different amounts per serving. Compare the two products first by cost per 500 mg of vitamin C, then by how many tablets you would need for the amount you and your clinician have settled on.

The 90-count Ester-C pack lists two 500 mg tablets for 1,000 mg per labeled serving. Nature Made sells a separately labeled 500 mg tablet.

What the smaller tablet can and cannot solve

Some customers on the Ester-C 500 mg listing found the tablets easier to swallow than a 1,000 mg tablet. That describes their experience with that particular brand. It does not give the dimensions of Nature Made’s tablet, and it does not change the two-piece serving on the Ester-C panel. Read the bottle before assuming less swallowing effort overall.

What customers reported

Our recommendation

Choose Ester-C if you prefer its specified two-tablet format and buffered formulation. Consider Nature Made when its distinct 500 mg tablet and ingredient list better match the supplement you intended to replace.
