Hello Todd - I use magnesium threonate by Designs for Health…a product called Neuro-Mag … at bedtime, along with my standard magnesium bisglycinate capsule; and, if I feel exceptionally stimulated at bedtime, I’ll add a chewable tablet of PharmaGaba by Natural Factors. While I typically do not have sleep issues, on occasion, the day’s events can linger in my thoughts and this calming combo works very well for me - without a morning residual ‘drugged effect.’ I have no negatives to report. My heart remains very calm.

If you like, I can share the Neuro-Mag tech data sheet with study references – just send me a PM.

Although I toggle on brands .. and one is the one Jackie recommends.... I had read same. I use for sleep- IDK if it really works or not. The only thing I don't like is it takes three pills for a dose. I wish I could find a powder. I always forget and like to take before bed and it gets stuck in my throat if I do right at bed. I have looked at a variety of brands and all seem to need 3 pills. Jackie I am curious where you get yours.. I will PM you

Also I sleep I personally am working with a therapist that deals with insomnia as related to sleep anxiety and does CBT-I. It is grounded proven therapy. I'm happy to elaborate if you are interested. (It's been a life long struggle for me )

I have used LEF Magnesium Thronate powder for years and it works well. I mix it with other powders and take it twice daily.

You can get it from iHerb or directly from LEF. [www.iherb.com] I buy most of my supplements from LEF during their annual sale but I occasionally get burned when I decide to change a supplement during the year.

I buy as many of my supplements if powder form for several reasons: no mixer or dyes in them, cost, easy to modify doses, etc. Other good sources are Pure Bulk Bulk Supplements.
