Source-backed LabelLens guides for reading supplement labels and comparing declared amounts, forms, and costs.
Magnesium compounds can weigh far more than the magnesium they contribute. Learn which label number LabelLens compares and why compound weight is not a substitute.
Reviewed Jul 18, 2026Read guide →Citrate, glycinate, oxide, chloride, and other forms differ, but the form name alone cannot determine the best product for every person.
Reviewed Jul 18, 2026Read guide →A 1,000 mg fish-oil headline does not necessarily mean 1,000 mg of EPA and DHA. Follow the Supplement Facts panel to compare like with like.
Reviewed Jul 18, 2026Read guide →Fish and algal oils can both supply long-chain omega-3s, but their EPA/DHA profiles and label details vary by formulation.
Reviewed Jul 18, 2026Read guide →Omega-3 chemical form can affect absorption under study conditions, but it should be interpreted alongside dose, meal context, label transparency, and price.
Reviewed Jul 18, 2026Read guide →Bottle price alone is a poor comparison. Here are the exact denominators LabelLens uses for servings, active amounts, and market-specific offers.
Reviewed Jul 18, 2026Read guide →Separate the declared creatine form from the amount, serving basis, price, and evidence—without turning a more elaborate ingredient name into a better-product claim.
Reviewed Jul 19, 2026Read guide →A label serving, a loading phase, a maintenance phase, and a normalized 5 g price are different denominators. Here is how to compare them without prescribing a regimen.
Reviewed Jul 19, 2026Read guide →Use the declared whey ingredient as a classification—not as a shortcut for protein grams, allergens, finished-product composition, testing, or suitability.
Reviewed Jul 19, 2026Read guide →Scoop size, serving size, protein grams, container weight, servings per container, and cost per 25 g answer different questions. Compare them without mixing their bases.
Reviewed Jul 19, 2026Read guide →Total CFU and microorganism identity are separate facts. A larger number—or a longer species list—does not establish a better result without strain- and use-specific evidence.
Reviewed Jul 19, 2026Read guide →A probiotic CFU number needs a serving basis, a shelf-life basis, and the product’s storage directions. Keep those qualifiers visible before comparing potency or price.
