The supplement stack tracker that catches overlaps and interactions.
A checklist tells you that you took your pills. It cannot tell you that three of them quietly tripled your zinc, or that one of them clashes with your medication. Mallet unbundles every product to the ingredient level, flags the overlaps and upper limits, and checks interactions, so your stack actually works for you.
You are not stacking products. You are stacking ingredients.
Branded supplements hide what they share. A multivitamin, a greens powder, and a standalone B-complex can each carry the same B6, zinc, or vitamin A, and no label adds it up across the three. You think you are taking one of each. Your body is taking a much bigger combined dose, and some of those totals can climb past a safe upper limit without you ever seeing it.
A list app cannot catch this, because it only sees the products, not the chemistry inside them. You need a tracker that unbundles every bottle to its ingredients, sums the same nutrient across the whole stack, and then checks those ingredients against your medications. That is the difference between logging supplements and actually managing them.
Ingredient-level unbundling
Every branded product breaks down to its real ingredients and doses, so a multivitamin becomes the twenty-odd nutrients actually inside it, not one tidy line.
Overlap and upper-limit warnings
Mallet sums each nutrient across your whole stack and flags the ones that double up or push past a tolerable upper intake level. These are the totals no label ever adds up for you.
Interaction checks with medications
Log your medications next to your supplements and Mallet surfaces known interactions, so a hidden conflict becomes a question for your doctor instead of a surprise.
Connected to your bloodwork
Map your stack against your actual lab markers to see what is working. Drop the doses that are not moving anything, and prove the ones that are.

Guides on building a stack that helps instead of piling up:
What is a supplement stack tracker?
A supplement stack tracker is an app that logs every product you take and breaks each one down to its individual ingredients. Instead of seeing a row that says multivitamin, you see the actual vitamins, minerals, and compounds inside it, with the dose of each. That ingredient-level view is what lets a tracker spot overlaps, flag upper limits, and check interactions, which a simple checklist app cannot do.
How does it catch overlapping micronutrients?
When you stack branded products, the same nutrient often shows up in several of them. A multivitamin, a greens powder, and a separate B-complex can each contain B6 or zinc, and the labels never add it up for you. Mallet unbundles every product to the ingredient level and sums the same nutrient across your whole stack, so you can see your real daily total rather than a guess.
Does it warn about exceeding safe upper limits?
Yes. Many nutrients have a tolerable upper intake level, the amount above which the risk of side effects rises. Because Mallet sums each ingredient across your entire stack, it can compare your combined daily total against that ceiling and flag the ones you are pushing past, which is easy to miss when the dose is split across three different bottles.
Does it check interactions with my medications?
Yes. You log the medications you take alongside your supplements, and Mallet checks for known interactions between them, then surfaces anything worth a conversation with your doctor. It is education, not a prescription. The point is to make a hidden conflict visible so you can ask the right question, rather than find out the hard way.
Can it connect to my bloodwork?
Yes. Upload a lab panel and Mallet maps your supplements against your actual markers, so you can see what is moving. If your vitamin D is already optimal, you can stop paying for the dose that is not doing anything. If a marker has not budged, that is a signal too. Tracking what you take is only half the picture, bloodwork tells you whether it is working.
