Vitamin D3 2000 IU Softgels
Nature Made is the most accessible USP-verified Vitamin D on the market. While it uses basic ingredients, the USP seal guarantees that what is on the label is exactly what is in the bottle, which is rare for budget brands.
Quality & Materials
Uses standard Cholecalciferol (D3) sourced from lanolin. Contains soybean oil and corn starch, which are acceptable but less 'premium' than MCT oil.
Evidence & Testing
USP (United States Pharmacopeia) verification is the highest standard for verifying potency and manufacturing purity in the US retail market.
Brand Transparency
Transparency is moderate; they don't provide individual batch COAs to consumers, but the USP audit process is a robust surrogate for transparency.
Value Assessment
Unbeatable value. You can often find a 250-count bottle for under $15, making it the best choice for budget-conscious consumers who still want verified quality.
Why Not Alternatives?
It beats generic store brands (Walgreens, CVS) and 'Amazon Choice' brands because it carries the USP Verified mark, ensuring it's not contaminated and actually dissolves properly.
