Dietary Supplement Analysis (NIH data)

What Dietary Supplement Analysis (NIH data) does

Dietary Supplement Analysis (NIH data) evaluates a set of supplements using product information from the NIH Dietary Supplement Label Database. It identifies products from names, barcodes, or NIH label IDs, then adds the declared daily amounts of vitamins and minerals across the routine. Results are compared with NIH reference intakes and tolerable upper intake limits for the supplied age, sex, and life stage.

The analysis can also consider medications, health conditions, and dietary intake. It reports relevant medication interactions from NIH fact sheets, safety signals for herbs from NIH and NCCIH material, and FDA recalls or adverse-event reports. Responses include a plain-language assistant summary in English or Spanish, with source-backed values and findings.

How it works

The remote MCP endpoint is available at https://agents.trackmysupplement.com/mcp. The same backend exposes HTTP routes for direct calls, including POST /v1/stack/analyze for routine analysis, POST /v1/products/lookup for barcode-based label lookup, and POST /v1/products/fda for barcode-based FDA checks. Product queries may be ordinary names such as a brand and dosage, while barcode requests use a UPC.

A stack request can include age, sex, life_stage, medications, products, candidates, diet, lang, and detail. Candidate products support what-if questions, such as testing an additional vitamin without treating it as part of the current routine. A typical diet adds food intake based on USDA data and NHANES estimates.

Data comes from the NIH Dietary Supplement Label Database, NIH Office of Dietary Supplements reference material, NCCIH herb fact sheets, NIH RxNorm medication normalization, openFDA, and USDA food data. The service also has a Pocket Network Beta TestNet offering identified as dietary-supplement-analysis.

Setup and configuration

For direct testing, send JSON requests to https://agents.trackmysupplement.com. The documented free trial permits up to 30 requests per minute and 100 calls per day per client; excess requests return HTTP 429 with a RATE_LIMITED code and a Retry-After header. The remote MCP URL can be configured in an MCP-compatible client.

Paid usage through Pocket Network requires an application staked for the dietary-supplement-analysis service on Beta TestNet and uses the documented relay endpoint. Operators can also run a supplier or gateway using the published multi-architecture image, although the supplied material does not specify additional environment variables or a local installation command.

Tools and capabilities

The Dietary Supplement Analysis (NIH data) MCP server supports these grounded workflows:

• Analyze a supplement stack and total daily nutrient intake.
• Compare nutrients with age-, sex-, and life-stage reference values and upper limits.
• Check medication interactions named in NIH sources.
• Report herb safety statements from NIH and NCCIH.
• Look up labels by UPC and search FDA recalls or adverse events by UPC.
• Return candidate-product what-if results and English or Spanish summaries.

Limitations and notes

Dietary Supplement Analysis (NIH data) is not medical advice and does not provide a diagnosis. Its interaction results reflect the statements published in the referenced NIH and NCCIH material; the interaction list is not exhaustive. A missing warning means that nothing was found to report, not that a product combination is safe.

The service reports what product labels declare and compares those declarations with published reference values. Label matching and reported recall or adverse-event results therefore depend on the available public datasets. Pocket Network relay use is paid, while the direct endpoint is described as a rate-limited free trial.
