Vitamin C sufficiency is very important to humanity, and freshly picked produce very expensive. Vitamin C seems to be largely unique among nutrients in how fragile it is, being destroyed with any significant storage or cooking. Supplementation with ascorbic acid in shelf-stable tablet form seems like a reasonable compromise.

Vitamin C is also one of the most abundant vitamins. there's a ton of vegetables and fruit that are very high in vit C (you can check my nutrient finder: https://kale.world/c ) . Rather than jumping straight to supplements, I prefer eating leafy greens. they're loaded with so much stuff: antioxidants, vitamins, minerals, fiber, etc. and, i've read so many times that often supplements don't provide the same benefits a…

Growing pest-free greens for 365 day availability (daily nutrition) is _incredibly hard_. It requires suburban housing, heated greenhouses, water and pesticide management, succession planting, fertilizer management, daily attention, etc, etc, etc. Not one person in a thousand achieves it. Buying produce at the supermarket for several dollars a day is dramatically easier, even if a high fraction of the vitamin C has decayed. Supplements are something on the order of 1-10 cents a day.

Well, as an experienced gardener I can tell you that growing perfect broccoli and cualiflower is very challenging, growing leafy greens is not.

if you have a desent sized garden and are constantly growing stuff in it, you will almost always have greens one way or another. all those failed broccoli result in a consolation prize: the leafy greens that come with the plant. and when they do go to seed, the plant gets super huge delivering pound after pound of leafy greens. similar things happen to lettuce and many other greens. and if you take the time to identify all the weeds growing, you'll notice that many of them are edible and can be added to the garden salad. the beets whose heads never developed properly, still have lots of green growth on top. and those french sorrel plants, once properly rooted will be hard to get rid of and you'll have pounds of leafy greens. Just keep growing and you'll see.

I've experienced this myself. Most of the year, i have waaayy too many leafy greens (much of it from failed brassicas, various weeds - which by the way are very nutritious) than i know what to do with and harvest at least 1/2 lb per day.

Do you live somewhere without a winter, by chance?
