I'm not a supplement person. Never have been. Capsules full of mystery powder, labels with seventeen unpronounceable things — no thank you. So when I started adding vegetable powders to my morning routine a while back, I needed to trust exactly what I was putting in my body. That's how I landed on Dr. Cowan's Garden, and it's where I've stayed.
Let me tell you what they actually are, because the name might throw you off if you haven't heard of them.
Started by a Doctor Who Got Fed Up
Dr. Thomas Cowan is a physician — an integrative cardiologist — who spent decades watching patients struggle with chronic illness and started asking hard questions about the food supply. His conclusion: we are deeply deficient in the kind of nutrition that comes from genuinely diverse, well-grown vegetables. Not factory-farmed, not monoculture, not the same three crops at scale. Real food. The kind your great-grandmother would recognize.
So he started a company to source and sell it. Small-batch vegetable powders made from single ingredients, grown biodynamically on diversified farms. That's the whole premise. Read their full story here — it's worth five minutes of your time if you care about where food comes from.
What They Actually Sell
The core of the product line is powdered vegetables. We're talking things like:
- Winter squash powder — deep orange, naturally sweet, great stirred into soups or oatmeal
- Leek powder — mild allium flavor, I use it in everything
- Threefold blend — their signature mix of ashwagandha, shatavari, and rhodiola, grown at altitude
- Beet powder, tomato powder, kale powder — but not the commodity versions. Specific varieties, specific farms, traceable.
They also carry garden seeds — heirloom, open-pollinated, the kind you can save and replant. If you're growing your own food, or thinking about starting, their seed selection is worth looking at alongside the powders. It ties the whole philosophy together: grow it right, then use every bit of it.
Prices run roughly $15–$55 depending on the product, with the powders landing in that middle range. It's not cheap by grocery store standards. But you're not buying grocery store product.
Why I Keep Coming Back
Here's what I tell people when they ask: it's the single-ingredient sourcing that gets me.
Most vegetable powders on the market are blends — and blends are where corners get cut. You don't know which farm grew which ingredient, you don't know if it was harvested at peak nutrition, and you definitely don't know if the "kale" in that blend was the nutrient-dense lacinato variety or whatever was cheapest that season.
Dr. Cowan's is one ingredient per jar. They tell you the farm or growing region. They use biodynamic practices, which go further than organic — the farm has to function as a self-sustaining ecosystem. That philosophy is either something you care about or you don't, but if you do care, it's hard to find another company doing it at this level.
The other thing: the flavor is real. Vegetable powders can taste like cardboard or like supplements. These taste like the actual vegetable, concentrated. That matters when you're trying to use them in cooking rather than choke them down in a glass of water.
The Bottom Line
I'm not telling you to overhaul your pantry or spend a hundred dollars all at once. Start with one powder — whatever vegetable you already love — and see what you think. The leek powder converted my husband, who was deeply skeptical. The winter squash converted me.
If you want to understand the company before you buy anything, start with the About page. Dr. Cowan writes plainly about why he started this and what he believes about food and health. Whether or not you buy anything, it's a worthwhile read.
Grow what you can. Source the rest carefully. That's the whole game.
