Supplement intelligence, normalized
Bextera Nutrition breaks supplement products into comparable specifications: active form, label dose, serving economics, testing evidence and the clinical research behind the ingredient.
Ingredient index
7 ingredient dossiers covering common supplement categories where formulation and label details materially affect comparison.
The most widely used and studied supplemental form of creatine, with the clearest performance evidence for repeated high-intensity efforts.
Creatine form, grams per serving, servings per container, cost per gram, additional ingredients and independent testing evidence
An essential mineral sold in multiple chemical forms, where elemental magnesium, compound form and serving size matter more than the raw weight of the magnesium compound.
Elemental magnesium per serving, chemical form, serving size, cost per 100 mg elemental magnesium, additional ingredients and testing evidence
A family of fatty acids where total oil, total omega-3 content, EPA, DHA and ALA should be recorded separately rather than treated as interchangeable label numbers.
EPA per serving, DHA per serving, combined EPA+DHA, source oil, serving size, cost per gram EPA+DHA and independent testing evidence
A water-soluble vitamin available in several supplemental forms. Form names are prominent in marketing, but the current evidence does not show different supplemental absorption rates among the major B12 forms.
Vitamin B12 per serving, cobalamin form, percent Daily Value, oral versus sublingual format, serving count, cost per 100 mcg and independent testing evidence
A fat-soluble vitamin commonly supplied as D2 or D3, where form, microgram-to-IU conversion and total daily exposure matter more than the size of the number printed on the front label.
D2 vs D3, micrograms, IU, amount per serving, serving frequency, other active ingredients and cost per normalized dose
A complete milk protein commonly sold as concentrate, isolate or hydrolysate, where protein yield and cost per gram are more useful comparison metrics than scoop size.
Protein per serving, serving weight, protein yield, whey form, cost per 25 g protein, additional ingredients and testing evidence
An essential mineral sold in several supplemental forms. The Supplement Facts panel reports elemental zinc rather than the total weight of the zinc-containing compound.
Elemental zinc per serving, zinc form, percent Daily Value, servings per container, cost per 10 mg elemental zinc, additional ingredients and independent testing evidence

Sunlight, foods and supplements can all contribute to vitamin D status, but they are not interchangeable sources.
Protein grams are only one line on the label. Calories, serving size, fiber, added sugar, saturated fat, sodium and price change the comparison.
Caffeine can improve some exercise outcomes, but dose, timing, tolerance and side effects matter more than chasing the largest milligram number.
Magnesium from spinach, legumes, nuts and whole grains is not evaluated the same way as elemental magnesium on a supplement label.
Serving size, active ingredient amounts, Daily Value and proprietary blends tell you more about a supplement than most front-label marketing.
How to read Bextera
Similar ingredient names can represent different chemical forms, protein fractions or fatty-acid compositions.
Scoop weight, compound weight and the amount of the relevant active ingredient are not always the same measurement.
Testing, certification and performance claims should be separated from claims that can be independently checked.
