Supplement Tracker

A supplement tracker that reads the label for you

Balnc’s supplement tracker builds your stack from the NIH Dietary Supplement Label Database, scores each product from 0 to 10 on dose, label transparency, safety, ingredient form and brand, and tracks your daily vitamin and mineral intake against the recommended amounts for your age and sex, adjusted for any health profiles you add.

How does the supplement quality score work?

The score is a weighted blend of five label-based factors, shown out of 10. It also raises flags you should know about, such as a dose above the upper limit for a nutrient or one that delivers only a small share of the RDA.

It is a reading of the label, not a lab test: Balnc does not independently test products for purity or contents.

What goes into the quality score
FactorWeightWhat it looks at
Dose30%How each nutrient compares with the NIH recommended daily amount
Safety20%Whether any nutrient exceeds its tolerable upper limit
Transparency20%How completely the label discloses its ingredients and amounts
Form15%How well the form is absorbed; liquids rate highest and gummies lowest, and forms such as methylfolate or magnesium glycinate score higher
Brand15%Whether the brand is verified

Where does the product data come from?

Search and import products from the NIH Dietary Supplement Label Database, which records the labels of supplements sold in the United States. If a product is missing, request it on the web with its barcode and photos of the label. Claude reads the label photos to fill in the details, and the request is reviewed before the product is added.

You can add medications to your list too, marked as prescription or over the counter, with details looked up from the FDA’s openFDA database.

Does Balnc check supplement interactions?

Yes, between supplements. Balnc knows 17 common nutrient pairings, including conflicts such as calcium and iron, pairs that work well together, and timing tips, and it shows NIH Office of Dietary Supplements notes on drug interactions for each nutrient. It does not yet check food against your medications or allergies.

For timing advice with sources, read when to take vitamin D, magnesium, iron, B12 and calcium.

How does RDA tracking work?

Balnc adds up the vitamins and minerals from your supplements and your food, and compares them with the recommended amounts from the NIH fact sheets for your age and sex. If you add health profiles (conditions such as an underactive thyroid or weight-loss surgery, medicines, nutrients a doctor said are low, or lab results), some targets and limits change to follow published guidelines, and each change shows the reason. Balnc doesn’t diagnose or treat; check dose changes with your doctor. Supplements you set to auto-check are logged for you each day, so your totals stay accurate without a manual check-in. A personal match score also rates how well a product fits your goals, overlaps with what you already take, covers gaps and sits with your medications.

The supplement tracker is part of the Pro plan.

Common questions

Is the Balnc quality score a safety rating?

Not on its own. It is a label-based score that weighs dose, safety against upper limits, transparency, ingredient form and brand. Balnc does not lab-test products, so check with a doctor or pharmacist before starting a supplement, especially alongside medication.

Can I track medications in Balnc?

Yes. You can add prescription and over-the-counter medications to your list, and details are looked up in the FDA’s openFDA database. Balnc shows NIH notes on known nutrient and drug interactions for the supplements you take.
