What supplements to take on a zero carb lifestyle?

I suffer from PCOS, Fructose Malabsorbtion & I'm sensitive to FODMaPS. That being said, there isn't much for me to eat without flaring up one of the other issues. I dont eat grains or dairy as well. So, I have gone zero carb. I only eat meat, fish & fat (ghee, coconut oil, olive oil). I will incorporate organ meats in the near future (when I can get over my gag reflex for them).

My question to you is: What supplements should I be taking? I've read to include Vit C (to prevent scurvy), and VIT D3 is another one I should take. But then I read all over where there are conflicting posts. Take a multi Vitamin, dont take it. Take Magnesium, Iodine, Selenium, Vit A, B, E & K, Cod Liver oil, Glutathion, probiotics. Are all those necessary? Which are the most important to take at this stage?

I am going to try stay zero carb for a few months, and then slowly incorporate veggies & starches and see if I can handle them etc. But for the mean time, I have been zero carb for 10 days, and I feel great! My skin is clearing up, I have energy, I feel satiated after every meal... I just dont want to fall short on the Vitamins & minerals by eating this way?

To me, supplementing with all of those vitamins and minerals mindlessly does not sound like a clever idea at all. That could lead to unpredictable stuff happening inside of you.

I think it wouldn't be such a bad idea to test first, and get someone to interpret your labs.

Anyway, here's what will not hurt:

  • Taking an epsom salt bath, swimming in the ocean, and drinking 100% cocoa powder for magnesium
  • Eating some beef liver every week (100-500g) for vitamin A, B12 and other B vitamins
  • Being outside every day from 10am to 2pm and exposing as much skin as possible to sunlight, gradually increasing time spent tanning, for vitamin D
  • Eating some seafood (fish, shrimp, mollusks, seaweed) for iodine, omega 3's and other important stuff. Squid fillet for example, has about 300 mcg of iodine per 100g, 1 sheet of roasted nori (2.5g) ??? 150 to 300 mcg.
  • Finding some canned cod liver, packed in own juice (oil) ??? it tastes super awesome: also a good source of omega 3's, and pretty high in vitamin A and D.
  • Drinking some quality mineral water with meals ??? at least magnesium is more bioavailable that way

There's some research that suggests you don't need that much vitamin c when carbs are not present, but I might be wrong. Anyway, Vilhjalmur Stefansson did not seem to suffer from scurvy too much on an ???all-meat??? diet.

For K, or B6 I don't have a plan. Plenty of selenium are in animal products you eat, so there's no need to worry.

This isn't the most informative or complete answer, but I hope you will find it helpful in some way.
