Not OP but I've had luck with zinc and magnesium aspartate supplements commonly available on Amazon. I take two caps that each are a net about 500mg an hour before bed, along with 1mg of melatonin. Been doing this for a lot of years now.

You need to be a bit careful with zinc. A doctor friend of mine compiled a load of data showing most zinc supplements are contaminated with cadmium, which is cumulative. I'm not sure if he's published yet. Edit, here's a paper by some other researchers: https://www.tandfonline.com/doi/abs/10.1080/09637480120057602 https://www.tandfonline.com/doi/abs/10.1080/0963748012005760...

  Thank you for this information. I'll either switch to a better brand or go straight magnesium.

  Thanks! It is also critical to balance zinc with copper, and supplementing a lot of zinc without copper can effectively cause copper deficiency, which is very serious.

  Fyi in the consumerlabs review for zinc, all products passed testing for cadmium levels with the highest (Nature's Bounty) having 0.5mcg/g. You basically need to be careful with any supplement since it's unregulated, and need to do a lot of careful diligence. It's a good sign if they are honest about their supplier and you trace back their supply chain. E.g. for many chelated supplements (zinc included), if you see a TRAACS trademark then the source is Balchem (Albion) which to my understanding is fairly well regarded. ConsumerLabs tested one such TRAACS product and found it to be 0.1 mcg/g cadmium, so likely most products using TRAACS zinc bisglycinate formulation should be similar. I also found some EU food safety application [1] which confirms that across 3 different manufacturers of zinc bisglycinate (one of which is Albion), all samples were < 0.1mcg/g [1] https://efsa.onlinelibrary.wiley.com/doi/pdf/10.2903/j.efsa.2008.718 https://efsa.onlinelibrary.wiley.com/doi/pdf/10.2903/j.efsa....
