What vitamins/supplements do y'all take?

What supplements do y'all take? Just curious!

I have a whole stack but I'm not the best at taking them daily. I am a little scared of supplements after hearing a few stories online about liver failure/heart failure due to taking supps.

ATM, I am trying to take a probiotics, krill oil and D3 daily. I also have some magnesium I think I'll start taking at night with my Ashwagandha.

Other then that, I also have potassium and Milk Thistle, as well as B12 chilling in my cupboard. I take the ashwagandha for my thyroid, and the milk thistle for my liver (which has a key role with thyroid functions). The B12 is leftover from when I was taking my iron last year, which seem to be fine now. The magnesium and potassium are because I eat low carb/keto. Oh and I also just got Kelp but I am a little scared to take it, I take it a few times per week not to overdo it.

My thyroid has been showing up slow as of recently (before I was eating low carbs, I actually had been eating a ''balanced'' macros diet around 1800cals and training moderately for a few months, but my weight wouldn't budge!).

I started low carb 6 weeks ago, about at the same time that my blood test results came back and lost 6lbs, and lost another 6lbs since starting keto 10 days ago. Might not seem like much but I actually haven't been this weight since after giving birth to my first child 4 years ago (I have 3 kids, the last is about to turn 1).

I know they always say check with your doctor first, but honestly they don't know jack. Apart from prescription medication of course, that they always want to shove down your throat. I was precribed Synthroid, without even seeing me face to face to talk about alternative approaches. I don't think she is educated very much about this issue. I haven't taking it as I don't want to resort to that just yet. I have another blood test scheduled for the end of the month and will see from there. AND ALSO! I had the Mirena IUD prior to this condition developing, and had it removed the same week I found out about it. No doctor will acknowledge a link of course, but I strongly believed it played a role.

Thanks ahead!

PS. I know no one will give medical advice, just looking for others to share their own experience! And interested in seeing what other people take and for what reasons.

TLDR:

Wondering what you guys take and why

My stack:
General health and immune system: Probiotics, Krill Oil
Because I eat low carb/keto: Magnesium, potassium
Because I want to heal my thyroid: Ashwagandha (clinical trials have shown benefits to thyroid function in people with hypo and hyper thyroid), milk thistle (liver supports thyroid functions), Kelp (for Iodine which is necessary for thyroid hormones processes), D3 (same as previous, and also I guess general health?)

Also, the thyroid problems were prior to eating low carb/keto when I was eating a ''balanced diet'' (1800cals+ while lifting 4x per week for about 30 minutes), got my Mirena (IUD) removed the same week I found out and went back to eating low carbs (which I tend to lean towards and have previous experience with from a couple years ago in between pregnancies, and felt amazing and dropped 25lbs which I didn't gain back, only gained weight back when I got pregnant again and was bed ridden, depressed and was overeating out of boredom).
