Only if you compare it to ultra-processed food. And that comparison is exactly the problem.

One GreenSky sachet is your greens for the day. Literal greens.

Leafy vegetables are among the most potent, most studied and most consistently recommended whole foods in human nutrition. They are also the most expensive, the most perishable, the most time-consuming to prepare, and the most likely to wilt in your fridge before you get to them.

We have spent generations being conditioned to expect food to be cheap. Ultra-processed food is cheap because the real costs: the farmer, the soil, the labour. The integrity of the ingredient have been removed from the equation and replaced with synthetic substitutes manufactured at scale.

Real food has real costs. A farmer grew this. A season produced it. A process that costs ten times more than conventional dehydration preserved it.

$7 a day is the cost of real food. Real vegetables. Real integrity. Real nutrition.

AG1 contains 75 ingredients across three proprietary blends. The individual amounts of those ingredients are not disclosed. You are paying for a formulation you cannot fully interrogate because the weights are hidden inside a proprietary blend. It also contains synthetic vitamins and minerals, is formulated in New Zealand, and is classified as a supplement, not a food.

Every other greens powder in the Australian market operates on the same principle. A long list of ingredients, some whole food sourced, some synthetic, blended into a powder and marketed as health.

GreenSky is not that.

Our entire ingredient list is vegetables. Australian-grown. Freeze-dried. Nothing added. No synthetic vitamins. No proprietary blends. No hidden weights. No imported formulations. No adaptogens. No fillers.

You can read everything in our sachet in under thirty seconds, because everything in our sachet is a vegetable.

Honest answer, the clinical proof is coming.

Optimal Greens is a new product. The University of Queensland research partnership, one of only two simulated human digestive system trials in the world, will determine with scientific rigour exactly what the body absorbs from each sachet. That research is funded, approved and waiting for the first production run.

We could make claims right now. The industry does it constantly. Health claims that sound impressive and cannot be verified. We chose not to.

What we can tell you is this.

Freeze-drying preserves up to 97% of the nutritional content of a whole vegetable, significantly more than conventional dehydration, cooking or cold-press juicing. The cellular structure of the plant remains intact. What goes into the sachet is as close to the whole vegetable as technology currently allows.

We can tell you that nearly thirty whole Australian-grown plants across three blends are in every sachet. We can tell you that the nutritional density is extraordinary. We can tell you that the feedback from our beta testers has been remarkable.

But we won't tell you it works until we can prove it.

Probably the most common thing we hear. And it deserves a straight answer.

Eating well and eating diversely are two different things.

Most people who eat well eat consistently... the same salad, the same vegetables, the same rotation of meals they know and trust. That consistency feels like health. And in many ways it is. But the emerging science of the gut microbiome tells us something important: your gut doesn't just need quality. It needs variety.

The research target is thirty different plants per week. Not thirty serves of vegetables. Thirty distinct plants, including vegetables, fruits, herbs and spices. Each one feeds a different strain of gut bacteria. Each one contributes something the others cannot replicate.

If you're eating well but eating the same things repeatedly, your gut diversity is likely narrower than you think.

One COMBO Greens box contains 21 whole Australian-grown plants across three blends: vegetables, fruits, herbs and spices. Freeze-dried. Nothing added. Used daily alongside the food you're already eating, it fills the diversity gap that even a genuinely healthy diet rarely closes.

It is not a replacement for eating well. It is what eating well looks like when you take diversity seriously.

Everything. And nothing else.

Here is the complete ingredient list for each blend.

NURTURE cucumber · green apple · bok choy · fennel · lemon · coriander · ginger · mint · linseeds

GROW cucumber · red apple · spinach · kale · lemon · parsley · ginger · mint · turmeric · linseeds

THRIVE orange · zucchini · broccoli · celery · spinach · lemon · dates · ginger · mint · basil · chia seeds · sea salt

That is the whole list.

No proprietary blends. No undisclosed weights. No synthetic vitamins. No preservatives. No sweeteners. No fillers. No numbers. No ingredients you cannot pronounce. No ingredients that require a biochemistry degree to evaluate.

21 whole Australian-grown plants: vegetables, fruits, herbs and spices. Freeze-dried at low temperature to preserve the cellular structure, nutrition and flavour of each one. Sealed in a single-serve sachet.

What is on the label is what is in the sachet.

In an industry where proprietary blends routinely hide the amounts of every ingredient behind a single combined weight, where a product can legally list spinach first and contain almost none, this level of transparency is not standard.

It should be. It isn't.

At GreenSky it always has been and it always will be.

Like plants. Real ones.

Not sweet. Not chalky. Not artificially flavoured to mask what's inside. Each blend tastes like the whole foods it's made from, because that's all it is.

NURTURE Light, refreshing and soothing. Cucumber and green apple lead. Fennel and mint finish cleanly. The lowest oxalate blend, gentle on digestion and easy to drink.

GROW Crisp and clean. Red apple and cucumber carry it. Kale and spinach are present but not overpowering. A grounded, green taste that feels like it's doing something.

THRIVE Naturally sweet and invigorating. Whole orange and dates give it warmth. Broccoli and celery anchor it. Basil and mint lift it. The most approachable blend for people new to drinking their greens.

All three work in a glass of cold water. All three work in a smoothie. All three work with a squeeze of extra lemon if you want brightness. None of them need to be masked, sweetened or disguised.

If you have been drinking commercial greens powders the first sachet will taste different. Because it is different. There are no natural flavours added to make it taste like something it isn't. It tastes like 21 whole Australian-grown plants, because that is exactly what it is.

Most people love it immediately. Some take a few days. Either way your gut doesn't need you to enjoy it. It just needs you to drink it.

Though most people do enjoy it. Genuinely.

No.

You can purchase a single box: 30 sachets, 30 days, with no subscription, no commitment and no obligation to continue.

Start there. See how you feel after 30 days of 21 whole Australian-grown plants daily. Then decide.

The subscription exists because most people don't want to stop. Not because we need them to continue. There is a meaningful difference between those two things and we think you deserve to know it.

If you choose to subscribe, here is what that looks like:

5% off every box. Free shipping. Cancel any time. No penalties. No lock-in periods. No fine print designed to make cancellation difficult.

If you choose to purchase once and never return, that is completely fine. We would rather you try it honestly than subscribe reluctantly.

What we have found across eight years and 1,200 loyal customers is this: people who experience genuine whole-food plant diversity consistently, who feel the difference that 21 real plants makes to their energy, their digestion and their sense of daily nourishment, tend to make it a non-negotiable.

And that's not us telling them to. It's their body telling them to.

But try it first. One box. Thirty days. See what real food does.

It's a fair question. The wellness industry has earned that scepticism.

Adaptogens. Superfoods. Activated charcoal. Collagen water. Nootropic mushroom coffee. The list of things that were going to change your health forever, and quietly disappeared from shelves eighteen months later, is long enough to make anyone cautious.

GreenSky is not a trend. And the difference is structural, not cosmetic.

Trends are built on marketing. GreenSky is built on a vegetable.

Vegetables have existed for as long as humans have. The gut microbiome research that underpins everything GreenSky does is not emerging science. It is decades of accumulated evidence pointing to one consistent conclusion: dietary diversity, specifically the variety of whole plants consumed regularly, is one of the most significant markers of long-term human health.

That is not a trend. That is biology.

What GreenSky does: applying pharmaceutical-grade freeze-drying to whole Australian-grown plants at consumer scale. This is not a new idea dressed up as innovation. It is an old idea executed with modern precision. Real food, preserved without compromise, made convenient enough for the life people are actually living.

The University of Queensland doesn't partner with trends. The Australian Taxation Office doesn't classify trends as GST-free food. Competitive government grants totalling $300,000 are not awarded to trends.

And a founder who spent eight years without a salary, rebuilt her business during cancer treatment, and funded independent scientific research when a marketing claim would have been faster and cheaper, is not chasing a trend.

She is finishing something she started.

This is the most honest objection on the list. Because we have all bought something with the best intentions and watched it gather dust on a shelf.

So let's talk about why Optimal Greens is different... and what you can do to make sure it isn't.

First, the format helps.

There is no blender. No measuring. No prep. No cleaning. No refrigeration. No remembering to defrost something the night before. One sachet. Tear. Pour into a glass of cold water. Done. Thirty seconds from closed box to finished drink.

The barrier to consistency is almost zero. That was deliberate. A product that requires effort gets skipped on hard days. Hard days are exactly when your body needs real food most.

Second, the placement matters.

Put the box somewhere you already look every morning. On the kitchen bench next to the kettle. Beside the coffee machine. Next to your vitamins if you take them. Habit science is clear. New behaviours attach most easily to existing ones. Optimal Greens attaches to whatever you already do every morning without thinking.

Third, the sachet travels.

Put three in your bag. Keep a box at work. Pack them for travel. Unlike every other whole-food option that requires a kitchen, a fridge or a blender, Optimal Greens goes wherever you go. Two year shelf life. No cold chain. No excuses.

The people who forget to use it are the people who put it in a cupboard.

Don't put it in a cupboard.

You shouldn't trust it because we say so. That's not how trust works.

Here is what you can verify independently.

The ingredients are on the label. All of them.

No proprietary blends. No hidden weights. No synthetic vitamins disguised behind a long list of impressive-sounding compounds. 21 whole Australian-grown plants: vegetables, fruits, herbs and spices. Freeze-dried. Nothing added. Read the label. Everything is there.

The research is independent.

GreenSky holds active co-investment research approval from the Food and Beverage Accelerator, hosted by the University of Queensland and supported by the Australian Government. Total project value $187,489. We are not required to fund this research. We chose to because in an industry that makes health claims nobody can verify, we wanted nature to be the judge. Not marketing.

The University of Queensland does not attach its name to products it hasn't interrogated. That endorsement was earned, not purchased.

The classification is government-issued.

A private ruling application has been lodged with the Australian Taxation Office classifying Optimal Greens as GST-free food — not a supplement. The Australian Government classifies food differently from supplements for a reason. We applied for that classification because we believe we qualify. The prior ruling for our previous product was successful.

The recognition is competitive.

$300,000 in competitive grants awarded by state and federal government. Runner Up, Organic Product of the Year, May 2026. Startupbootcamp. Female Founder Accelerator Program. Food and Beverage Accelerator Industry Growth Program. Queensland Social Enterprise Council registered social enterprise.

None of these are self-declared. Every one was assessed, applied for and awarded by an independent body.

The founder is accountable.

Sky Hunt. Founder and CEO. sky@greenskyoptimal.com.au. She reads every email. She built this alone, without a salary, without a team, through cancer treatment, because she believed in it too much to stop.

She is not hiding behind a brand. She is the brand.

And the reviews are real.

120 of them. 99% five stars. From real people with real names who consumed real food and felt real things.

You don't have to trust GreenSky. You have to decide whether the evidence is sufficient.

We believe it is. We built everything around making sure it would be.
