VIOscan
Explore real charts & comparisons · no signup required
Two clear tools: an interactive supplement dashboard and a human-studies newsletter with a full article library.
Compare vitamins, minerals and omega‑3 side by side. See amounts, units and nutrient forms in clear charts — including EPA and DHA across 100+ fish oils.
No mice, no hype: only studies in living humans. Eleven independent digests, each sent every two weeks. Every study gets a plain-language finding and a practical takeaway.
“I was able to compare 8 magnesium supplements in under a minute and found magnesium glycinate for $15 vs my old magnesium oxide for $22.”
“I had no idea my multivitamin used vitamin D2! I switched to vitamin D3 + K2 with VIOscan and my follow‑up levels moved into range.”
“I was overpaying for my omega‑3. “1000 mg fish oil” refers to total oil, not EPA and DHA, so I switched to another product with 600 mg of EPA and DHA per softgel for $35.”
“My expensive multivitamin had zero methylated B vitamins. No wonder I was so exhausted.”

VIOscan captures the exact form of each ingredient in every supplement (e.g., vitamin B12 as cyanocobalamin vs methylcobalamin) and shows it directly in comparisons and charts.
In the VIOscan dashboard, you can see whether an omega‑3 product is IFOS‑certified, compare its quantified EPA and DHA amounts, and view their concentrations as percentages. The dashboard also includes whether it is Ethyl Esters, Natural Triglycerides, Phospholipids, or Re‑esterified Triglycerides or non specified.
You can view chart bars either per serving (as typically shown on supplement labels) or per capsule: an advanced feature unique to VIOscan.
Yes. VIOscan can show each nutrient in a supplement versus the Recommended Dietary Allowance or Adequate Intake, and the safe upper level (RDA, AI, and UL). You will see simple sentences with amounts and units, so you can quickly tell if a dose is below the target or close to the safe limit.
