How to make your own fresh green vegetable powder at home that’s low in oxalates and other gut-damaging antinutrients. Saves money and is so much healthier!

Green vegetable powders are a very popular type of dietary supplement. They’re a convenient way to add extra vegetables to the diet without having to cook or otherwise prepare them.
Parents especially love them because vegetable powder is easily hidden in smoothies or soups for picky eaters.
The problem is that commercial brands of green vegetable powder have a sinister side that most consumers are only vaguely aware of (if at all).
First, they are very prone to rancidity.
Once you powder green veggies, they will get stale very quickly if not refrigerated. Given that the shelf-life product you buy is at least weeks old, it seems wise to avoid them.
Second, most brands of powdered veggies I’ve reviewed over the years use veggies high in anti-nutrients like oxalates.
These vegetables need to be carefully prepared at home (discarding the cooking water) or avoided altogether for those with digestive sensitivities or those on a low-oxalate diet.
Finally, brands containing water green are at risk of contamination from cytotoxins and heavy metals.
See the linked article for more details on the risks of commercial green vegetable powders with study citations.
Or of course, the solution to these problems is to create your own fresh and safe version!
You will be pleased to know that the process is very simple.
Bonus! You can make your powdered veggies oxalarm by simply choosing the right veggies!

Thoroughly dry the vegetables in a dehydrator set at 35–40 °C (preferred method). If you don’t have a dehydrator, you can use an oven set to “warm” and no higher than 140F (check the veggies every hour to avoid over-drying).

Pulse dried greens in a food processor to desired powder consistency.
