Individually, each one seems useful. Together, not all of them are needed.
I'm K, a PhD in Food Science. I take the facts on supplement labels apart, line them up and look at them together: how many sources of the same nutrient you have, how much they add up to, and what the label doesn't say at all.

The numbers on a label can rarely be compared as they stand
One bottle of vitamin D says 5000, another says 125
They are the same amount: one is given in IU, the other in micrograms.
A fish oil with “3000” in its name
One softgel is actually 1000 mg of fish oil; 3000 is the amount in three softgels.
“450 mg magnesium glycinate”
Only 50 mg of it is elemental magnesium; that conversion is given on the product's own page.
“Magnesium citrate 815 mg”
How much elemental magnesium? The label doesn't say. Here the conclusion is “unknown”.
These are questions of formulation and labelling rules, not of nutrition. Line up two of your products (in Chinese) →
Where to start
Three ways in, at different depths: look at two products for free, sort out a whole shortlist when you need to, or get a signed confirmation for one real purchase decision. All three are currently provided in Chinese.
Quick check of two products
- For
- You want to see what the labels of two products look like side by side
- You get
- Label facts, differences in units and forms, combined amounts and information gaps, listed by fixed rules. No recommendations, scores or rankings; no sign-up needed
Decision workspace
- For
- You have a few candidate products and want to sort them out before deciding
- You get
- For 90 days: product × ingredient matrix, ranking, 3 time snapshots, Decision Pack export (PDF + CSV)
L3 personal expert review
- For
- You use 3–10 supplements and have a real purchase decision within 30 days
- You get
- 1 person, 1 non-medical purchase goal; a signed confirmation (PDF) + 1 written clarification; no meetings
Most wasted spending may come not from buying too little, but from deciding in the wrong order.
WHAT YOU MAY BE DOING NOW
- 01Something changes
- 02You look for a quick reason
- 03You add a new supplement or functional food
- 04You change several things at once
- 05You can't tell what actually mattered
- 06You keep adding
WHAT LVA™ DOES FIRST
- ADefine the question
- BLog the changes made in the same period
- CSeparate facts, inferences and gaps
- DJudge what can be attributed
- EGive boundaries, not answers
LVA™ (Life Variable Architecture) is Life Variable Lab's method of judgment: it starts from public facts, breaks a choice down into the life variables it involves, and separates facts, inferences and gaps. Rather than rushing to find a “root cause” for a change, it first lowers the risk of attributing it wrongly. See the full method →

WHAT WE DO
Label facts, ingredient forms, how doses are expressed, source checks.
WHAT WE DON'T DO
Diagnosis, treatment, medication or individual supplement advice; where a doctor, pharmacist or dietitian needs to judge, we say so clearly. Boundaries →
Making scientific information easier to understand and consumer decisions better informed.
