My Mom Has a Sensitive Stomach. This Is the Only Greens She's Comfortable Drinking.

Every greens powder left my mom bloated. So I spent close to 2 years making one she could actually drink. This is how it happened, and what went into the tub.

Chapter 1

My Mom Tried Them All

My mom tried them all: the big-name greens powders everyone talks about. Every one of them left her with digestive discomfort and bloating she didn't need.

Between that, the taste and the gritty texture, she never stayed consistent. And I understood why.

“Nobody keeps drinking something that makes them feel worse.”

So I started working on a greens powder she could actually drink.

Chapter 2

Close to 2 Years. 8 Rounds of Revisions. 10+ Samples.

We never removed an ingredient to make it easier. We adjusted doses until the texture and the balance were right.

The hardest part was taste. Taste is why my mom never stuck with a greens powder, so it had to be right. Making something this good for you actually taste good was a real challenge. But we did it.

What Went Into the Tub

I wanted everything she needed in one scoop, and nothing that upset her routine. It starts with her gut, then adds the greens. Six blends, each with its amount on the label:

  • Enzyme Catalyst Blend325 mgFive digestive enzymes that support the breakdown of proteins, fats, carbs and plant fiber.
  • Fiber & Digestive Support600 mgPrebiotic fiber, including chicory inulin, to feed good bacteria and support regularity.
  • Probiotic Blend12B CFUThree spore-based strains, stable on the counter and built to make it through stomach acid.
  • Theorist Digestive Blend2,065 mgOrganic greens and algae: spirulina, chlorella, spinach, kale, moringa and more.
  • Antioxidant Superfood Blend2,075 mgPomegranate, acai, tart cherry, camu-camu and other fruits.
  • Adaptogen & Mushroom Blend315 mgMaca, ashwagandha, ginger, cordyceps, reishi and fennel seed.

“I was never going to compromise on the probiotics.”

Most probiotics are fragile. Heat, moisture and stomach acid can wear them down before they reach your gut, which is why so many need to live in the fridge. We use spore-based strains that stay dormant inside a natural protective coat, like a seed.

“One of the best-tasting formulas.”

“Rania called me personally.”

“Product is very good! Had a little problem with the shipping price but I was contacted by Rania and she made everything right by refunding me an overcharge mistake. Rania went above and beyond by calling me personally… Best customer service I've had in a long time!”

It Was Finally Done

It tasted amazing, it mixed smoothly, and after a month of taking it every day, I felt the difference myself. Now it's the greens my mom drinks.

If you've given up on greens powders the way she had, I made this for you too.

A Few Questions

What does it taste like?

Mango or Berry, sweetened with stevia leaf extract and monk fruit. Taste was the hardest part to get right and took 10+ samples. It stirs into cold water with no blender. If it isn't for you, you have 30 days for a full refund.

I have a sensitive stomach. Is it right for me?

Everyone's body is different, so we can't promise how it will feel for you. Super Greens was made for Rania's mom, who never felt right on other greens powders. If you have a medical condition, check with your healthcare provider first. And you have 30 days to decide, with a full refund if it isn't right for you.

How do I take it?

Stir one level scoop into 8 to 12 oz of cold water, juice or a smoothie, once a day. No blender needed. No caffeine, so morning or evening both work.

Do the probiotics need the fridge?

No. They are spore-based strains in a natural protective coat, so they are stable on your counter or in a suitcase.

I take medication. Is it okay for me?

Please check with your healthcare provider before starting any new supplement.

How do returns work?

If Super Greens isn't right for you, contact us within 30 days of delivery for a full refund. You don't need to return the tub or explain yourself.
