How We Rank (Editorial Policy)

What Zynava Does

Zynava provides three core tools to help you make informed supplement decisions:

1. Personalized Supplement Plan Builder

Our AI-powered quiz asks you about your wellness goals, lifestyle, dietary preferences, and budget. Based on your responses, we compile and present product information to help you explore options that may align with your specific needs. This tool helps you discover products you might not have considered otherwise, all based on objective ingredient analysis rather than marketing claims.

2. Cross-Retailer Price Comparison Tool

Our price comparison system aggregates real-time pricing from multiple trusted retailers, allowing you to see the best available price for any supplement across different vendors. But we go beyond simple price comparison — we help you make apples-to-apples comparisons by accounting for:

  • Strength and Dosage: We normalize prices based on the actual amount of active ingredients per serving, so you can compare a 500mg capsule to a 1000mg tablet fairly.
  • Supplement Form: Whether a product comes in capsules, tablets, softgels, powders, or liquids, we account for bioavailability and absorption differences when presenting value comparisons.
  • Cost Per Serving: We calculate the true cost per effective serving, not just the bottle price, so you can see which product offers the best value for your specific needs.
  • Package Size: We factor in bulk discounts and subscription pricing to show you the most economical way to purchase, whether you need a single bottle or a multi-month supply.

This comprehensive approach ensures you're comparing products fairly and finding the best value, not just the lowest sticker price. All prices are pulled directly from retailer websites and updated regularly to reflect current availability and promotions.

3. Supplement Label Checker

Simply take a photo of any supplement label, and our AI-powered system reads and analyzes the label to flag positives (like third-party testing certifications, quality indicators), potential concerns (such as proprietary blends with undisclosed amounts, artificial additives), and other important details you should know about. This tool helps you understand what's in the supplements you're already taking, with no purchase necessary.

How We Organize Product Information

Our listings are driven by a system that organizes product information across multiple objective criteria. We compile and present information on thousands of supplements to help you explore options that align with your wellness goals, preferences, and budget. Our methodology focuses on:

  1. Ingredient Quality: We assess purity, third-party testing certifications, ingredient sourcing, and the forms of ingredients used (e.g., bioavailable forms vs. cheaper alternatives).
  2. Safety & Compatibility: We filter products based on your specific demographic profile (age, gender, activity level) to help identify potential contraindications and ensure options align with your individual needs.
  3. Value Analysis: We calculate cost-per-serving to help you understand the true value of each product, not just the sticker price. This helps you compare products fairly across different brands and retailers.
  4. Goal Alignment: We match products to your stated wellness goals, dietary preferences, and lifestyle factors to surface options that may be relevant to what you're looking for.

Our evaluation system is designed to be objective and independent. We organize product information based on actual ingredients, quality indicators, and value — not marketing claims or brand popularity. This means you may see lesser-known brands ranked alongside or above well-known brands if they offer better formulations or value.

Editorial Independence: Brands cannot pay to alter their rankings or listings. We maintain a strict firewall between our evaluation methodology and any affiliate partnerships. Our listings are based solely on product analysis, not advertising relationships.
