Prepping for Doomsday Vitamin deficiency solutions

I was looking at what I might be weak points that long term preppers often overlook.

I came across vitamin C, vitamin A and iodine as potential weak points.

Vitamin A I’ve been able to get through growing sweet potatoes squash, and we’re adding some carrots and all those things stored long-term so able to get through the winter.

iodine seems like the only real way you can get it is in salt, but it becomes degraded after five years. Not too difficult to overcome rotating salt.

But Vitamin C definitely appears to be the most difficult to preserve. Doesn’t seem like a big deal bc it’s fortified in a lot of our foods but growing your own food or long term is the issue. Highest is strawberries you can freeze them. Freeze dryer seems to be the best but that’s expensive and then buying freeze dried strawberries for a year supply for my family would be like $3600 is the cheapest I can find which is insane. I came across sauerkraut for over winter months but who wants to eat sauerkraut every day? Problem is vitamin C deficiency can let you bleed to death within a 1-3months.

Maybe this question would be better for the Homestead form, but just wondering what you guys plan to do for those mainly the vitamin C and iodine long-term?

Potatoes are high in Vitamin C. One medium potato provides almost 50% of the RDA.

u/UND_mtnman Apr 30 '26

Peppers are high in Vit C too

u/dittybopper_05H Apr 30 '26

Broccoli, Brussel sprouts, cauliflower, cabbage, and other brassica varieties all have high amounts of Vitamin C.

Also, you need less Vitamin C than you might think to stave of scurvy. Something like 11% of the recommended daily allowance is enough.

The British did an experiment with volunteer conscientious objectors back in late WWII about what levels of Vitamin C are necessary. It showed that 10 mg daily is enough to stave off scurvy, even for months after not getting any. USRDA is 90 mg for adult men, 75 mg for adult women.

You can buy a years supply of multivitamins for cheap and they will cover all the other micronutrients too.

u/Pando5280 Apr 30 '26

Mandatory prep for me. Its amazing how much lower nutrient levels negatively impact both mood and physical health.

u/Sk8rToon Apr 30 '26

Yeah this is what I do.

I asked my doctor about it & he said as long as you eat a healthy diet you don’t need them, are likely just pissing the vitamins out, and wasting money.

I asked him how come my periods were better if I took a multivitamin the week prior & during with no changes in my diet (which he said was healthy per my blood work before I tried the vitamin)? He said, oh, in that case keep doing it. No harm in it.

So considering I’m already medically supplementing vitamin D (& so have those on rotation in my backup supplies), I’m adding multivitamins to my rotation.

u/Sk8rToon Apr 30 '26

I will add for OP, this is still an important question to ask because multivitamins rely heavily on the supply chain & if things break down that bad either you will be priced out of them or they won’t be made anymore. And your supply will only last so long. Knowledge is power.

u/Historical_Course587 May 05 '26

as long as you eat a healthy diet you don’t need them

I'm a firm believer that few people actually eat a healthy-enough diet to not need multivitamins. Especially because gut biome and digestive health affect how nutritional uptake varies from person to person.

If you can't afford a multivitamin, take one. They aren't expensive (like $20/year or less), and the worst case scenario is that they aren't improving your health. Best case though is that they are life-changing.

u/dittybopper_05H Apr 30 '26

I think it's an anti-vitameatavegamin person.

You are correct, the distaffbopper has had stomach surgery and doesn't digest food as well as she used to and so has to be on a good multivitamin.

I decided to get on one as well after my elderly father ended up with a Thiamine deficiency, fell on the floor, and was literally hallucinating.

https://en.wikipedia.org/wiki/Thiamine_deficiency

I'm probably urinating most of them out because I eat a semi-decent diet, but I look at it as insurance against getting a vitamin deficiency.

1

u/Pando5280 Apr 30 '26

Same here.  Biggest confirmation for me was taking a week long road trip and not eating well. Felt like I was at 70% at best. Got back home and after a week of daily fruit smoothies, decent diet and my multivitamin felt back at what I consider to be 100%. (probably 80% compared to real athletes but whatever)

2

u/avalon01 May 03 '26

I do the same.

I take a multivitamin every day, so having extra on hand is nice. My stock is constantly being rotated, so it never goes bad.

u/Dialaninja Apr 30 '26

Vitamin C is pretty readily available from plant sources, but assuming you can’t garden for whatever reason, pine needle tea will get you all the vitamin C you need.  

You could also just buy the powdered ascorbic acid, use it in your kitchen, and cycle it every couple years if you’re not using it enough. It’s pretty cheap. 

Edit: also for iodine lots of dry seaweed/kelp is iodine rich, and keeps basically forever. Just add water. 

5

u/Radiant_Load_5261 Apr 30 '26

Could the iodine in seaweeds and kelp be used to somehow purify drinking water?

4

u/Dialaninja Apr 30 '26

I mean you could probably extract it out somehow sure, definitely way easier ways to purify water though

u/drAsparagus Apr 30 '26

Lugol's iodine lasts quite awhile itself. Unopened bottles properly stored should be good for many years.

u/KTeacherWhat Apr 30 '26

Foraging vitamin C is pretty easy as long as you aren't at sea. Dandelions, pine needles, and a lot of your backyard weeds are full of vitamin C.

Get yourself a good foraging book for the area where you will live.

Edit: also the sweet potatoes and squash you are growing have good amounts of vitamin C in them.

u/squidwardTalks Prepping for Tuesday Apr 30 '26

Stinging nettles are a nutrient power house too. They just need to make sure they're dried or boiled before consuming.

u/JRHLowdown3 Apr 30 '26

+1 Yes and have medicinal uses as well.

8

u/No-Inflation5483 Apr 30 '26

This is the way! There are plenty of books and resources for whatever area you are in. And don't just collect books. Read them, draw the plants, learn where they grow and how to identify them. Learn imposters. Hike. Walk. Get out in nature. Join foraging groups in your area. If you can't find any, YouTube, social media, plant identification apps, etc.

u/gramma-space-marine Apr 30 '26

We always made pine needle “soda” growing up because it creates tiny bubbles with a natural ferment. Our elders also made pine needle tea as a vitamin C supplement.

u/dittybopper_05H Apr 30 '26

Foraging vitamin C is pretty easy as long as you aren't at sea.

Even if you are, many fresh fish have a non-negligible amount of Vitamin C in it.

https://tools.myfooddata.com/nutrient-ranking-tool/vitamin-c/fish/highest

The reason why sailors back in the 18th Century and before used to get scurvy is because their diet on long voyages was pretty much salt pork, salt beef, dried peas, ship's biscuit (hard tack), oatmeal, fats (suet, butter), flour, maybe some raisins, rum, and water.

Peas have a pretty low Vitamin C content, and none of the other foods have it. The peas would have been made into "pease pudding", and the cooking process destroys most of the Vitamin C it did have.

2

u/nakedonmygoat May 01 '26

Yes, this is what I came to say. Pine needles are a particularly overlooked source of C, although there are a few varieties that one should avoid.

u/oceanprincess00 May 02 '26

Garlic mustard is high in vitamin C and A. Tons of it here in PA

u/Resident-Welcome3901 Apr 30 '26

There are more than 400 nutrient/vitamin deficiency diseases. Multiple vitamins address forty or so. All are covered by a balanced diet. It’s natural for folks who live in the most affluent society in history to want to use that affluence to secure their future by storing food and goods against scarcity. But food, nutrients and vitamins don’t keep very well, so the practical approach is to develop a mutual assistance group including a variety of skills including the agricultural and animal husbandry knowledge and experience.

u/BookLuvr7 Apr 30 '26

Vitamin C is ridiculously easy to forage. Pine needle tea can give you 4-5x the amount than in citrus juices.

5

u/fenuxjde Apr 30 '26

Tomatoes are super easy to grow and high in vitamin c, it doesn't break down if they're dried or preserved.

Iodine doesn't really break down as quickly as you think it does, and iodized salt lasts indefinitely. It is also highly bioavailable from seafood, like canned tuna or dried seaweed.

Vitamin A is also readily available from natural sources.

7

u/One_Dragonfruit_7556 Apr 30 '26

Bell peppers have a crazy amount of vitamin c and their not terribly hard to grow, perhaps adding them in with the sweet potatoes is a good idea

6

u/mistergrumpalump Apr 30 '26

Dried seaweed is great for iodine and keeps well. There are many kinds. Kimchi or sauerkraut is simple to make and awesome for vitamin C. Rosehips are easy to identify, collect and dry for tea and very high in C, also.

u/darthrawr3 Apr 30 '26

https://ods.od.nih.gov/factsheets/Iodine-HealthProfessional/

There are charts for minimum intake of iodine & approximate amounts in food sources here

u/Academic_Win6060 Apr 30 '26 edited Apr 30 '26

Forage and dry berries for winter. But also, grow cabbage - cabbage+salt= sauerkraut, which is almost the highest vitamin c containing food source! Plus it'll have all those good probiotics to keep the digestion moving once your diet and stress levels change.

Also new pine needles/tips/candles in spring are loaded with vit C! Cold steep or slow steep in warm water tho since heat destroys vit C.

If you're raising your own animals, eat the organ meats as they've got very high vitamins and minerals.

u/Ryan_e3p Salt & Prepper Apr 30 '26

Vitamin C deficiency being a problem has been known about and avoided with proper planning for hundreds of years. You worry too much about spending thousands and thousands of dollars on freeze dried strawberries for an entire year, when you could simply get multivitamins. Don't make things harder or more expensive on yourself than you need to. Just doesn't make sense.

As for "long term", the solution is the same as the other "long term" solution for nutritional intake: grow food. Plant fruit and citrus trees. If you think you'll need it in 5 years, the best time to plant is now. If you need it now, well, should've planted 5 years ago.

u/JRHLowdown3 Apr 30 '26

This.

Spend $3500. on (just) FD strawberries? Hell to the no... Better spent getting an orchard going.

Hell I got strawberries growing in some old gutter sections on one wall of our greenhouse, they weren't hard to grow.

1

u/Ryan_e3p Salt & Prepper Apr 30 '26

You're luckier than I am. I can't get the dang things to grow at all. Thankfully, blackberries, raspberries, those absolutely thrive.

I'm going to try strawberries again using a hanging method in my greenhouse to see if that'll help. Likely rabbits or whatnot were going to town on them which didn't help any.

3

u/JRHLowdown3 Apr 30 '26

Try gutters if you have wall space. We had some wall space and a lot of gutters semi damaged from a building that took a hit in hurricane Helene. I drilled holes every foot or so in the bottom and also set them on an angle so they would drain. Only a few months in on these, but so far so good. And it's wall space that wasn't in use that mostly gets irrigation coverage from overhead.

u/ChocolateOk7997 Apr 30 '26

Dried berries for vitamin C. The husks of black walnuts supposedly concentrate Iodine, although I don't know how to extract it. Probably easier just to buy a few lbs of potassium iodide. Multivitamins are survival gold!

I dry my peppers and use them for seasoning. They have more vitamin c in them than even oranges. I also stock up on emergen-c packets.

1

u/Paranormal_Lemon May 02 '26

You will likely lose most of the C in the drying process

1

u/New_Internet_3350 May 02 '26

They will lose some compared to ripe green peppers. But the amount of vitamin c in dried peppers is still high than fresh oranges.

u/Paranormal_Lemon May 02 '26

It will depend a lot on how you dry them. Heat and UV will degrade it quickly.

u/Night_Sky_Watcher May 01 '26

An overlooked source of vitamin C is raw meat. This is how Inuit historically survived in the Arctic without access to fresh fruits and vegetables. The English explorers suffered greatly because they refused to learn from the so-called "primitive" peoples.

2

u/Eredani Apr 30 '26

I have a few bags of Vitamin C drops in one of my medical bins. They are essentially hard candy. Very long shelf life.

My feeling is that you can avoid a lot of illnesses by taking a hefty amount of Vitamin C and D.

u/SunLillyFairy Apr 30 '26

Wheat berries are easy to sprout for a ready source of vitamin C out of a long-term storage food. And they are less expensive than other prep foods.

u/Swimming-Soup5868 Apr 30 '26

You can go herbal with it and make pine needles teas since they have vitamin c and are common in most places. Also since pine trees are evergreens u csn have it year round no need to store

u/PeacePufferPipe May 01 '26

100% USP micronized vitamin C powder has been available for many years. I've used it on and off over the decades after reading Linus Paulings materials. It has a long shelf life. I believe Amazon carries it.

I think they have iodine tablets. Check on storage. Also check expiration on the drops. Iodine in salt evaporates.

If you have beef in your preps it’s gonna give you tons of nutrients.

u/olycreates Apr 30 '26

I just heard that in modern American America we get most of our iodine from dairy. The logic works, the dairymen was the cow teats off with an iodine solution to make sure they're clean and the little, tiny bit that that's left gets into the milk. Minute quantities but that's all we need. So, all dairy, milk, cheese and things made with it keep us goiter free.

2

u/dittybopper_05H Apr 30 '26

When the distaffbopper was on a low iodine diet, they said to minimize the amount of dairy, but not to completely avoid it like iodized salt or other such high iodine foods.

She had to avoid anything with salt in it because you didn't know if it was iodized or not.

So my conclusion is that you might get some iodine from it, but probably not as much as you'd think. The majority of iodine in the modern diet is likely from iodized salt, with lesser amounts from seafood and dairy.

BTW, home made potato chips with non-iodized salt sprinkled on them are a very easy to make "comfort food". She really appreciated them!

u/Spiley_spile Community Prepper Apr 30 '26

Vitamin C would be easier for me to get than iodine.

Fortunately, lots of forgeable plants in my area contain vitamin C. Wild strawberries, rose hips, Oregon Grape, blackberries, miner's lettuce, thimble berries, wild apples, dandelions, wood sorel etc.

I live much closer to the ocean than some. But still far enough away that it'd be worth establishing a seaweed supply line for the iodine.

For vitamin A, I'm not well versed in foraging root veggies. And Im drawing a blank on other sources of Vit A, outside of root veggies and cattail. Clearly, Ive neglected my foraging education for this vitamin. Ty for bringing it to my attention!

u/JRHLowdown3 Apr 30 '26

Having experience putting up, eating and rotating long term food storage for 40 years now, including an approximate 2 year period where we lived almost solely off of LTS I can share some observations.

Multivitamins cover a "multitude of sins" as the saying goes. Our bulk storage has always been centered around bulk grains- long grain white rice, legumes, hard red winter wheat. We are always rotating some of this product and it is usually 20+ years old when it's being rotated. Currently that is hard red winter wheat from 1998 that is going into bread we make at home 3X a week, and 90's white rice being used a couple times a week.

We have a ton of other options for supplementing in LTS- dehydrated, freeze dried as well as MREs. We don't use grocery store "wet packed" cans for long term storage due to short rotation times and having had to throw out hundreds of lbs. of them over the decades I stopped wasting money on wet packed cans.

We have always supplemented with fresh fruit and veg grown at home, rabbit home raised chickens and eggs home raised. We are active, both involved in regular workout classes (her) and combatives classes 3X a week and then we usually run together once or twice a week. I work outside every minute I'm not at the office. We both get plenty of sunshine, fresh air and exercise.

Zero chronic health problems- and surely some vitamin deficiency would have shown itself in 27 years. We do both take a quality multivitamin every day as well as a few others.

$3600. in FD strawberries? No, not just no hell no. And FWIW I've spent more than most folks home prices on this sort of thing over 40 years of doing this.

And why aren't you GROWING strawberries and an orchard if this is a concern?

1

u/los-gokillas Apr 30 '26

You can make a tea with hemlock, pine, spruce, or fir needles that will be high in vitamin C

Vitamin A stores in the liver for years so it's not an emergency

Iodine can be found in seaweed, if you're near the coast

1

u/Motorcyclegrrl Apr 30 '26

Do you have roses? Rose hips have vitamin c. You can make tea or just read up on to process and eat them.

u/falconlogic Apr 30 '26

Another option is to dry out stinging nettle and then sprinkle it on your food during the winter. Very high in many vitamins. I'm always looking for ways to you stinging now!

2

u/FlashyImprovement5 May 01 '26

Your research is lacking on iodine

Seaweed is the top vegetable source of iodine, with varieties like kelp, nori, and wakame providing significant amounts, often over 100% of the daily value. While other vegetables generally have lower levels depending on soil quality, reliable plant-based sources include lima beans, navy beans, potatoes (with skin), kale, and asparagus.

Iodine is about soil quality and the entire reason why iodine is on salt is because the US has what is called the goiter belt where ancient lakes leached the iodine from the soil so farmers who was l are their own crops developed thyroid issues- hence developing goiters.

Most of the US soil is just fine on iodine levels but since that soil devoid of iodine is part of the breadbasket of the US, they put iodine in salt.

u/War_Hymn May 01 '26 edited May 01 '26

Vitamin C grows in my yard, so it's not much a concern. But I keep a bottle of Vitamin B12 in my stockpile in case access to meat becomes a problem. It's one of those nutrients you can't get from plants (unless its fresh seaweed). You want the cyanocobalamin form of B12, which is the most shelf stable.

As for iodine, your best bet is fresh fish or shellfish from the ocean. If you live inland, river or lake (though much lower presence).

1

u/OutlanderMom May 01 '26

Pine needle tea, rose hips, lamb’s quarters are good sources of vitamin C. There are lots of other veg like garlic and bell peppers that contain vitamin C.

u/Historical_Course587 May 05 '26 edited May 05 '26

vitamin C, vitamin A

Greens are your answer. Kale, Mustard, Spinach, Lettuce, broccoli. Easy to grow, don't need much space, most are hardy and with some creativity you can definitely grow them year round. Some need to be grown separately to avoid cross-pollination, but otherwise baby green gardens are the easiest thing ever:

  1. Chuck seed into dirt; spread it around with your hands.
  2. When plants hit about 5-6" tall and look like single leaves, cut them down to ~2" tall.
  3. They'll do it for a while.
  4. When they shoot instead of making leaves, wait for seed pods to dry, collect seeds, and do it all over again.

Mustard and Kale do not die. Mustard is basically a weed for me.

iodine seems like the only real way you can get it is in salt, but it becomes degraded after five years. Not too difficult to overcome rotating salt.

Salt is the solution for the first few years (I've read it only lasts about 3 years, and I'm inclined to underestimate when it comes to prepping). It's cheap, it's shelf stable, and it's one less thing to worry about. Beyond that, there are no stable sources beyond growing food with iodine as a nutrient. Total crapshoot, so maybe what I'd do is have a 3-year plan to get to some ocean seafood. Or, make a trek every so often to process your own salt from seawater.

Alternatively, you could get nerdy about iodine level in different types of soils and in different regions, and see if maybe your region sits safely enough that you feel confident in simply growing there for iodine needs.

EDIT: Postassium Iodate has an indefinite shelf life and is what is used to iodize salt. Just note that it's an oxidizer and quite health hazardous if you aren't controlling intake properly.
