A puff piece for Thrive Ultimate, because I like it

I like this stuff. Is there actually a good reason why?

Nathan Voisey··17 min read

I’m just going to disclose my bias immediately.

I like Thrive Ultimate Greens.

I’m not sponsored by Thrive. This isn’t an advertisement. I have no particular reason to convince you to buy it.

I tried AG1 first. It was fine. I understood why people liked it.

Then I tried Thrive. And for whatever reason, Thrive simply seemed to work better for me.

I felt calmer. I felt more energized. I had this difficult-to-quantify feeling that I’d checked off a piece of my daily nutritional requirements—that something useful had gone into me that morning and I could get on with the rest of my day.

I didn’t get quite the same feeling from AG1.

Thrive also tastes better to me. It costs considerably less. It’s Canadian. And I can buy it in Canada without importing my morning green drink from the United States.

So this article has an extremely sophisticated scientific hypothesis:

I like this stuff. Is there actually a good reason why?

Time to ruin a perfectly good subjective opinion with research.

First, what am I actually drinking?

Thrive Ultimate Greens is made in Ontario and currently sells for $69.99 CAD.

The ingredient list is unusually broad.

It includes greens and grasses such as barley grass, alfalfa, parsley, kale, spinach, and watercress; algae and sea vegetables including spirulina, chlorella, dulse, kelp, wakame, and nori; fruits and vegetables including pineapple, papaya, pumpkin, beetroot, carrots, blueberries, broccoli, cauliflower, and Brussels sprouts; and then another layer of botanicals and plant compounds including milk thistle, ginkgo, hawthorn, dandelion, nettle, Siberian ginseng, green tea, grape-seed extract, quercetin, lutein, resveratrol, and lycopene.

There’s also inulin, an essential-fatty-acid complex, and lecithin.

So this isn’t simply: powdered spinach.

It’s more accurately a broad plant-food and botanical mixture.

That matters because one of my complaints with the concept of greens powders generally is that ingredient count can become marketing theatre. Putting 73 ingredients on a label means nothing if 60 of them exist as ceremonial dust.

The real questions are:

  • How much material is actually in the serving?
  • Are useful ingredients included in meaningful amounts?
  • Is the formulation mostly food, or mostly fillers and flavouring?
  • Is anyone checking what’s actually in the tub?

And: Does any of it have human evidence behind it?

The obvious comparison: Thrive vs. AG1

AG1 is the elephant in the green-drink room.

It has spectacular branding. Excellent marketing. Podcast hosts have spent years telling us about it.

And, to give AG1 credit, underneath the marketing is a genuinely sophisticated formulation.

The current AG1 Next Gen formula uses a 13-gram serving and includes substantial vitamin fortification: 500 mg vitamin C, 20 mg vitamin E, 400 mcg B12, 680 mcg DFE folate, 20 mg zinc, 250 mg potassium, vitamin K2, and several other quantified nutrients.

It also contains probiotics and compounds such as CoQ10, alpha-lipoic acid, and inositol.

So if I came into this article intending to prove that AG1 was mostly expensive green-coloured marketing powder, the research did not cooperate.

AG1 is actually a pretty serious product.

And scientifically, AG1 has an important advantage over Thrive. Someone has actually studied the finished product.

AG1 wins the clinical-research round

In 2024, researchers published a randomized, double-blind, placebo-controlled study involving 30 healthy adults consuming AG1 or placebo for four weeks.

AG1 produced some changes in particular bacterial taxa, although it did not dramatically transform overall microbiome diversity. Researchers found no adverse effect on digestive quality of life, bowel frequency, or stool consistency, and reported a possible improvement in digestive quality-of-life scores that narrowly missed conventional statistical significance.

It’s a small study. But it’s an actual randomized trial of AG1 itself, rather than a collection of studies on its individual ingredients.

Another randomized crossover trial published in 2026 studied 20 resistance-trained adults. After two weeks, AG1 supplementation increased the number of micronutrient Estimated Average Requirements participants were meeting and selectively increased several bacterial taxa.

Again:

  • small study;
  • short duration;
  • healthy people;
  • not proof of extraordinary health transformation.

But real evidence.

A separate 2026 randomized crossover study tested nutrient absorption after a single 13-gram AG1 serving. Blood concentrations increased for most of the micronutrients researchers measured.

So yes: the nutrients actually got into the bloodstream.

There is an important caveat. Several authors on these studies were AG1 employees, and AG1 funded all three studies, the first in part.

That doesn’t invalidate a randomized trial. It does mean I would like to see independent researchers replicate the results.

Still, if we’re scoring these products honestly:

Product-specific clinical research

AG1 wins. Comfortably.

I couldn’t find comparable published clinical trials testing Thrive Ultimate Greens as a finished product. That’s a real weakness.

So why do I prefer Thrive?

This is where objective comparison becomes interesting.

Because the thing that has the most published clinical evidence isn’t automatically the thing I prefer using.

The first reason is extremely mundane.

Thrive tastes better.

That’s subjective.

There’s no randomized controlled trial capable of proving to me that I enjoy one drink more than another.

I drank AG1. I drank Thrive. I prefer Thrive. That’s the entire study.

Thrive itself conducted a blind taste comparison and reported Ultimate Greens scoring 9/10 versus 4/10 for AG1.

However, before we get too excited about that result, we should point out something fairly important: Thrive conducted the comparison.

The company that makes Thrive concluded that Thrive tastes best. Stop the presses.

To the company’s credit, it publishes its methodology and accompanying data, but I wouldn’t cite that score as independent evidence.

My own taste comparison is equally biased. But I’m the one drinking it every morning.

So for my purposes: Thrive wins.

Price is much less subjective

Here’s where Thrive starts becoming difficult for me to ignore.

Thrive currently lists Ultimate Greens at: $69.99 CAD for 60 servings.

That works out to roughly $1.17 CAD per serving.

For comparison:

Green drink Current listed pricing Approximate serving economics
Thrive Ultimate Greens $69.99 CAD / 60 servings ~$1.17 CAD
SUBI Super Juice ~$39.99 CAD / 40 servings ~$1.00 CAD
Genuine Health greens+ mixed berry $74.99 CAD / 50 servings ~$1.50 CAD
Nested Naturals Super Greens ~$35.95 CAD / 30 servings on Amazon.ca ~$1.20 CAD
AG1 US site: $79 subscription / 30 servings; $99 one-time $2.63–$3.30 USD before Canadian currency conversion

Prices as of October 2026.

Current prices can obviously change.

AG1 does ship to Canada, but its Canadian purchasing economics still have to contend with U.S.-dollar pricing and cross-border purchasing.

Thrive is made in Ontario and operated from Collingwood.

For someone living in Canada, that’s not merely patriotic window dressing.

It affects:

  • price;
  • shipping;
  • currency;
  • availability;
  • and general purchasing friction.

Price and Canadian convenience

Thrive wins.

What about what’s actually in the scoop?

Thrive conducted its own detailed competitor analysis in 2026.

We obviously have to treat this cautiously. The author is a co-founder of Thrive.

However, what’s interesting is that the company didn’t simply write:

Thrive = amazing. Everyone else = garbage.

Their own analysis actually gave AG1 the strongest score on several formulation-quality measures.

Using their methodology, Thrive counted 43 active ingredients above 10 mg in Ultimate Greens versus 44 in AG1.

AG1 also scored strongly on active ingredient mass and extract content.

That’s useful. It suggests these are both substantial formulations rather than one serious product and one tub of flavoured grass.

Thrive’s argument is basically:

AG1 may be somewhat denser and more sophisticated, but not enough to justify the enormous difference in price.

That’s a much more defensible argument than pretending AG1 is bad. And I largely agree with it.

AG1 is more like a greens powder crossed with a multivitamin

This may explain one of the biggest differences between the products.

AG1 explicitly fortifies the product with substantial amounts of isolated vitamins and minerals.

For example, one serving provides:

  • 500 mg vitamin C;
  • 400 mcg B12;
  • 20 mg zinc;
  • 680 mcg DFE folate;
  • 90 mcg K2;
  • plus meaningful amounts of vitamins A, E, B1, B2, B6, and others.

That gives AG1 a very strong nutrition label.

It also means AG1 isn’t merely powdered plants. It’s effectively a hybrid: greens powder + multivitamin/mineral supplement + probiotics + functional ingredients.

That’s not inherently bad. In fact, if you’re trying to reliably fill defined micronutrient gaps, it’s arguably an advantage.

Thrive takes a different approach. Its formulation leans more heavily toward dried plant foods, grasses, algae, sea vegetables, botanical extracts, prebiotic fiber, and plant compounds.

That distinction matters.

Because when I said Thrive felt like it was giving me something AG1 missed, the objective research didn’t produce a neat explanation saying:

“Aha! Nathan was deficient in Compound X and Thrive contains exactly 37 mg more.”

Actually, AG1 has considerably stronger quantified micronutrient fortification.

So my subjective experience doesn’t neatly match what you’d predict by simply reading a vitamin label.

And that’s okay. Personal experience isn’t required to produce a biochemical confession.

Why might I feel calmer?

This is the part where it would be extremely tempting to work backwards from my experience and manufacture an explanation.

I felt calmer.

Thrive contains Siberian ginseng, green tea, ginkgo, essential fatty acids, inulin, and a variety of plant compounds.

Thrive itself markets some of the formulation around stress support.

Therefore: Siberian ginseng did it!

Maybe. Or maybe not. We don’t know the answer.

Without a controlled trial, adequate dosing information, blood work, and a way to isolate variables, my experience could reflect:

  • an ingredient;
  • several ingredients;
  • better digestion;
  • correction of some minor nutritional insufficiency;
  • my overall routine;
  • expectation;
  • placebo;
  • random variation;
  • or something we haven’t thought of.

My experience is still real. Our explanation for the experience is what’s uncertain. That’s an important distinction.

The same goes for energy

I noticed better energy.

That doesn’t automatically mean Thrive contains an energy-producing wonder compound.

Its ingredient list contains several plausible candidates—Siberian ginseng, green tea, beetroot, spirulina, nutrient-containing plant foods—but the finished product hasn’t been clinically demonstrated to produce my particular experience.

This is where supplement marketing often commits a logical trick.

Research says:

Compound X has demonstrated Effect Y at Dose Z.

Product contains Compound X.

Therefore:

Product produces Effect Y.

Not necessarily.

  • Does the product contain Dose Z?
  • Does the combination alter absorption?
  • Is the population comparable?
  • Does chronic use behave the same way?
  • Has the finished formulation been tested?

Those questions matter.

So I’m not going to tell you Thrive is clinically proven to make you calmer and more energetic. It isn’t.

I can tell you: that’s what I noticed when I took it.

Third-party testing matters more than fancy ingredients

Greens powders introduce another problem that deserves more attention.

They’re concentrated agricultural products. Leaves. Roots. Algae. Seaweed. Herbs. Plant extracts.

Those materials can bring unwanted companions:

  • heavy metals;
  • microbial contamination;
  • pesticide residues;
  • or ingredients that simply aren’t what the supplier claims they are.

This is where both Thrive and AG1 do something I like.

Thrive publicly posts lot-specific third-party Certificates of Analysis for Ultimate Greens and its other products.

That is excellent practice.

AG1 takes testing seriously too.

AG1 is NSF Certified for Sport and says every batch is tested for contaminants including heavy metals, microbes, allergens, and banned substances. It also tests things such as caffeine and oxalates.

So I wouldn’t claim Thrive crushes AG1 here.

Quality-control infrastructure

AG1: excellent.

Thrive: excellent, with particularly nice public access to batch COAs.

Call it a draw.

Genuine Health deserves more respect than it usually gets

While researching this article, Genuine Health greens+ kept popping up.

And it deserves mention because it has been around forever by supplement-industry standards.

Its current formulation contains grasses, sea vegetables, fiber sources, probiotics, botanical extracts, and other superfoods.

The mixed-berry version currently lists at $74.99 CAD for 50 servings.

More interestingly, greens+ actually underwent a randomized, double-blind, placebo-controlled trial back in 2004.

Researchers enrolled 105 women for 12 weeks.

The primary vitality outcome narrowly missed conventional statistical significance at p=0.055, while a secondary energy measure significantly favoured greens+.

The researchers’ conclusion was appropriately restrained: positive but not conclusive.

That’s approximately how supplement science should be discussed.

Not: MIRACLE SUPERFOOD PROVEN TO SUPERCHARGE ENERGY.

More like: Interesting result. Keep studying it.

For Canadians wanting an established domestic greens product, Genuine Health remains a credible competitor.

SUBI is the interesting minimalist

SUBI takes another approach. Its Super Juice blend is essentially dehydrated plants.

The ingredient list includes matcha, kale, spirulina, barley grass, wheatgrass, chlorella, peppermint, açai, goji, maca, and a fruit-and-vegetable mixture.

A Canadian retailer currently lists a 40-serving bag around $39.99 CAD. That’s approximately a dollar per serving. That’s compelling.

If what you want is:

“Give me powdered plants without trying to recreate an entire supplement aisle in one scoop”

SUBI makes a strong argument.

I would happily put it in the Canadian shortlist.

What about Nested Naturals?

Nested Naturals is another credible alternative.

Its Super Greens product combines organic greens with fiber, probiotics, and digestive enzymes, and the company describes a four-stage batch-testing process covering botanical identity, microbial contamination, heavy metals, and potency.

The formulation is less expansive than Thrive or AG1, but it has a straightforward strength: organic greens + gut-support ingredients + substantial testing.

It’s a perfectly sensible product. It simply doesn’t give me a compelling reason to switch from something I already like.

My completely biased scorecard

After researching this far more than any reasonable person needs to research green powder, here’s how I’d summarize it.

Category Winner Why
Product-specific clinical research AG1 Multiple recent randomized studies
Quantified vitamin/mineral coverage AG1 Extensive fortification with disclosed amounts
Canadian price/value Thrive / SUBI Both dramatically cheaper than premium competitors
Ingredient diversity AG1 / Thrive Both unusually broad formulations
Whole-food/botanical emphasis Thrive Broad plant, algae, seaweed, and botanical mixture
Simplicity SUBI Essentially concentrated/dehydrated foods
Long Canadian track record Genuine Health greens+ has decades of history
Public lot-specific test reports Thrive Current COAs easily accessible by lot
Sport certification/testing pedigree AG1 NSF Certified for Sport
Taste Thrive According to the deeply rigorous scientific instrument known as my mouth
Canadian convenience Thrive Made and sold domestically
What I personally want to drink tomorrow morning Thrive Which is ultimately the point

That is not a landslide.

AG1 beats Thrive in some meaningful ways.

If someone told me:

“I want the product with the strongest current product-specific clinical evidence and explicit vitamin/mineral dosing, and I don’t care very much about price,”

I’d probably tell them to look seriously at AG1.

If someone said:

“I want a Canadian greens product with a broad ingredient base, transparent batch testing, good taste, and dramatically better economics,”

Thrive becomes extremely compelling.

Things I would change about Thrive

A proper puff piece should contain complaints. Otherwise we’re just writing marketing copy.

So here are mine.

Give the scoop a longer handle.

This is an extremely unscientific complaint.

The scoop handle is too short. When the bag is full, no problem. When you’re getting toward the bottom, you’re reaching your hand farther and farther down into a bag of green powder trying to retrieve the scoop.

It’s annoying.

This is exactly the kind of tiny usability problem that probably never shows up in a formulation meeting because it has absolutely nothing to do with nutrition.

But when you’re using a product every day, these little things matter.

Give me a longer scoop. Problem solved.

Publish the formulation more clearly.

I’d like a beautifully boring technical page showing exactly what is in a serving, in what amounts, with the botanical forms and extracts clearly identified.

If you’ve built a good formulation: show your work.

Do a randomized clinical trial.

This is the big one.

AG1 has started building genuine product-specific evidence. Thrive should too.

Take 100–200 people. Randomize them. Use placebo control. Run it long enough to matter. Measure actual nutrient biomarkers, subjective energy, gastrointestinal outcomes, microbiome changes, and whatever other claims the product wants to make. Pre-register the study. Publish the results even if they’re boring.

If Thrive wants to position itself as a science-oriented Canadian alternative to AG1, this would be the next obvious move.

And no, this doesn’t replace vegetables

A scoop of green powder is not a salad.

It doesn’t reproduce the physical food structure, fiber volume, calories, chewing, water content, or complete nutritional matrix of eating a varied diet.

That’s not what I use it for. I think of it as insurance against imperfect behaviour.

I am going to have days where my vegetables are magnificent. I am also going to have days where nutritional excellence consists of realizing at 8 p.m. that potatoes don’t count as a colourful vegetable strategy.

The green drink creates a floor. Not a ceiling.

That concept matters to me much more than the magical-superfood interpretation.

The weirdly important question: will you actually drink it?

After all of this research, one variable keeps returning. Adherence.

The scientifically exquisite powder you hate drinking has a major flaw. You won’t drink it.

The slightly less sophisticated powder sitting on your countertop that you genuinely enjoy making every morning might have considerably more practical value.

Taste matters. Price matters. Availability matters. Convenience matters.

Because health habits only compound when they survive contact with ordinary life.

That’s one of the reasons Thrive works for me. I don’t have to convince myself to drink it. I like it.

So did the research prove my puff piece?

Sort of.

What surprised me most is that Thrive actually gives AG1 a pretty good run for its money. Considering the enormous difference in price, the two products ended up much closer than I expected once I compared their formulations, testing, and ingredient breadth.

They aren’t identical products—AG1 leans more heavily into explicit vitamin and mineral fortification, probiotics, and certain functional compounds, while Thrive leans more toward a broad plant, algae, sea-vegetable, and botanical formulation—but they occupy much more comparable territory than their price tags would suggest.

It didn’t prove that Thrive is objectively the world’s greatest greens powder.

In fact, AG1 handed it a fairly decisive defeat in one category I care about: finished-product clinical research.

AG1 is also stronger if you want clearly quantified vitamin and mineral fortification.

Genuine Health has legitimate evidence and decades of history. SUBI offers remarkably good Canadian value. Nested Naturals offers a credible organic option with good testing infrastructure.

So the research didn’t produce:

THRIVE DESTROYS ALL COMPETITORS WITH FACTS AND LOGIC.

Good. That would have made this article suspicious.

Instead, what I found was something more useful.

Thrive is inexpensive for what it contains. Its formulation is broad. It emphasizes actual plant ingredients rather than merely padding the nutrition label. It publishes batch-specific testing. It is manufactured in Ontario. It tastes substantially better to me than AG1.

And, for whatever combination of physiology, nutrition, routine, and personal response is involved, I feel better when I take it.

That last statement isn’t clinical evidence. It’s a personal observation.

But personal observations are allowed to matter when you’re deciding what to put into your own body every morning.

So after all this reading, comparison, skepticism, ingredient checking, and study hunting, I have arrived at the highly technical conclusion I started with:

I like Thrive Ultimate Greens.

And regardless of the science and research I did on this, after using it, I like it and will keep using it.
