I remember that FDA said that ADI of saccharin is 15mg/kg bw

1. What the FDA sources in this set actually say about ADIs for sweeteners

The FDA materials in the search results state that the agency “established an acceptable daily intake (ADI) level for each of the five high-intensity sweeteners approved as food additives” and provide ADI tables for sweeteners, but the specific ADI number 15 mg/kg for saccharin is not presented in those FDA pages excerpted here ^{[1] [2]}. The FDA consumer pages and regulatory summaries confirm saccharin is regulated as a food additive and that ADIs exist, but the provided snippets do not show a 15 mg/kg ADI for saccharin ^{[5] [6]}.

2. Other authoritative or scientific sources show lower ADIs for saccharin

Multiple scientific summaries and reference sources in the results list saccharin’s ADI at lower values: a ScienceDirect topic page and related reviews state the FDA lists an ADI of 5 mg/kg for saccharin, and historical JECFA changes lowered prior values to 2.5 mg/kg at one point ^[3]. A downloadable FDA “Safe Levels of Sweeteners” chart is included in the results, implying official ADIs are tabulated there, but the excerpted material does not reproduce a 15 mg/kg value for saccharin ^[2].

3. International regulators have adjusted saccharin’s ADI recently — EFSA example

The European Food Safety Authority (EFSA) is cited as raising saccharin’s ADI from 5 mg/kg to 9 mg/kg in a November 2024 report — that is a clear example of changing international assessments and shows divergence between agencies and eras of review ^[4]. This demonstrates ADIs can be revised as new evidence accumulates and that different authorities may set different ADIs.

4. Where the 15 mg/kg figure likely comes from — possible mix-up with other sweeteners

The number 15 mg/kg appears in the search results as the ADI for other sweeteners (e.g., acesulfame potassium or sucralose in some FDA-education charts), and several secondary sources list 15 mg/kg as an ADI for a sweetener — but those snippets do not attribute 15 mg/kg to saccharin in the FDA primary pages provided here ^{[7] [8] [9]}. That suggests the 15 mg/kg memory may reflect a conflation of ADIs across different sweeteners rather than an FDA saccharin ADI supported by the supplied documents ^{[7] [8]}.

5. Conflicting secondary sources and the need for the primary table

Some consumer-aimed pages and later summaries (e.g., Medical News Today, other health blogs) repeat a 15 mg/kg ADI for saccharin, while others show 5 mg/kg or cite JECFA reductions to 2.5 mg/kg — the provided corpus shows clear inconsistency among secondary outlets ^{[7] [10] [3]}. The authoritative way to resolve this is to consult the FDA’s ADI table PDF or Code of Federal Regulations entries directly; the results include a direct FDA PDF titled “Safe Levels of Sweeteners” and the CFR entry for saccharin but the snippets here don’t reproduce a 15 mg/kg saccharin value ^{[2] [11]}.

6. Practical takeaway and recommendation for verification

Available sources here do not confirm an FDA ADI of 15 mg/kg for saccharin; instead, the cited FDA and scientific-material snippets point to lower ADIs (commonly 5 mg/kg or historical lower values), and recent EFSA action raised theirs to 9 mg/kg ^{[2] [3] [4]}. To settle the discrepancy definitively, consult the FDA “Safe Levels of Sweeteners” chart (downloadable PDF) or the current Code of Federal Regulations entry for saccharin referenced in these search results ^{[2] [11]}.

Limitations: this analysis uses only the provided search results and their snippets; the exact numeric ADI the FDA currently lists for saccharin is not printed word-for-word in the snippets here, so I avoid asserting a single definitive FDA figure without that explicit quote ^{[2] [11]}.
