Why Zena

A Certification You Can Trust

USDA Organic means something. Every ingredient is traced from farm to finished product, delivering carefully sourced, plant-based nutrition from nature.

  • Federally regulated: earned, not claimed
  • Farms go 3+ years free of prohibited pesticides or synthetic fertilizers
  • All ingredients traced to certified organic sources
  • Farms, facility, and Zena are all certified
  • Independent certifier audits Zena every year

Premium ingredients. Not premium prices.

Most greens powders charge luxury prices for the same organic ingredients. We don't. Certified-organic, third-party-tested nutrition at a price that means you don't have to choose between health and wealth.

  • I have been taking this everyday for the last 2 months. People have asked me what skin care I am using because my skin looks great and the only thing different was adding super greens into my daily routine. LOVE IT!

Frequently asked questions

What are organic supergreens?

Organic supergreens is a daily powder made from 70+ USDA-certified organic greens, fruits and vegetables, plus prebiotic fiber and probiotics. Mix one scoop or stick pack with cold water to help fill nutrient gaps and support gut health and energy.*

Is Zena third-party tested?

Yes. Every batch is tested by an independent third-party laboratory for safety, quality and purity, including heavy metals and microbial contaminants. Nothing ships until it clears.

How does Subscribe & Save work?

Choose a 1-month plan (20% off, ships every month) or a 3-month plan (40% off, ships every 90 days) on any product page. Your first subscription order ships free, and you can skip, swap or cancel anytime from your account.

What is the free gift with the 3-month plan?

Start a 3-month plan and we add a free tub of Creatine Gummies to your first order. Start a 3-month Liquid Collagen plan and the free gift is Supergreens Gummies instead. The gift is added automatically in your cart.

Can I find Zena in stores?

Yes. Zena Organic Supergreens is on shelves at Costco warehouses nationwide. Use our store locator to find the warehouse nearest you, or order online for delivery to your door.

What if Zena isn't right for me?

Every order is covered by our 30-day money-back guarantee. If you're not happy for any reason, contact us within 30 days of delivery and we'll make it right.
