What users say

“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.”

James Thompson

“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.”

Emily Carter

“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.”

Daniel Brooks

“My expensive multivitamin had zero methylated B vitamins. No wonder I was so exhausted.”

What is VIOscan?

Professional dashboard to compare supplements by amounts, units and bioavailable forms with omega‑3 analytics.

What do I get?

Comprehensive dashboard (1000+ products), side‑by‑side charts, and fast selection by brand, category or benefit.

How do you cover different nutrient forms?

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.

How do you track Omega‑3 products?

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.

How is the data visualization of charts?

You can view chart bars either per serving (as typically shown on supplement labels) or per capsule: an advanced feature unique to VIOscan.

Can I compare a product with recommended intakes?

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.

Key insights for informed choice

  • Nutrient gaps are common in adults and older populations; patterns often include vitamin D, iron (in women), magnesium and omega‑3 shortfalls1,2.
  • Targeted supplementation can improve status biomarkers (e.g., 25(OH)D for vitamin D; omega‑3 index for EPA+DHA) when diet alone is insufficient3,4.
  • Form matters: chelates (e.g., bisglycinate) and re‑esterified triglyceride omega‑3s may support tolerance and uptake vs inorganic salts or low‑quality oils5,6.
  • Aging & wellbeing: adequate vitamin D and omega‑3 intakes are associated with musculoskeletal and cardiometabolic benefits in adults, within evidence‑based dosing windows3,4,7.
  • Quality supplements: evidence‑based formulations with verified label accuracy may help maintain nutrient sufficiency, support wellbeing and healthy aging when used within safe, clinically studied ranges1–7.
