Questions about this assessment
Why does 100% Pure Niacinamide Boost have a No known risks rating?
No higher-risk ingredient flags are shown in the assessed entries. Ingredients without a matched rating are marked Not assessed, not No known risks. The product score is a stored assessment, not a clinical safety guarantee.
Does the niacinamide rating cover every ingredient in this product?
No. Niacinamide appears in the recorded formula, but its individual rating applies to that ingredient, not automatically to the whole product. Check the other ingredient ratings, any grey Not assessed entries and the stored product assessment. A niacinamide percentage or a product name is not a substitute for checking the full list.
Has every ingredient in 100% Pure Niacinamide Boost been assessed?
2 of 2 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.
Does this assessment apply to my 100% Pure Niacinamide Boost?
Only if the ingredient list on your packaging matches the recorded formula shown here. Formulas can differ by market and change over time. Compare the full list, not just the product name; report a mismatch if it differs.
Does this pregnancy assessment also establish breastfeeding suitability?
No. This page presents a pregnancy-focused product assessment. Do not infer a breastfeeding conclusion from its score or label; breastfeeding requires a separate assessment of the formula and how it is used.
