I noticed some neuro-inflammatory symptoms last night that I attribute to the calcium (again, I'm sensitive in that sense). Thus, I'm not going to press any further with it. I enjoy the stimulation, but I can't abide the cost. Again, I'd caution people to be careful with combining calcium and threonate, but especially if you have any (inflammatory) neurological or cardiac issues.
A last note on the magnesium threonate. I may have undersold it a bit for anxiety. As I before stated, it only mildly reduces anxiety but, as gamesguru points out, there is both a chronic and an acute effect. The chronic effect for me, with magnesium threonate, is pretty exciting. What I have found is that it does, indeed (see the below study), stop the over-generalization of fear (anxiety). Anxiety becoming progressively overly generalized with time, instead of dissipating, is my experience with it. Over time, anxiety began to invade my sleep and peak during my waking period. I have found that the mag threonate has seemed to reduce this effect to where clinical anxiety is not noticeable on many mornings when it otherwise would be (given my dreams, the general pattern, etc). I also suspect that it is making me a more calm communicator in general (others may not notice a large difference, but I do in how my brain reacts when I listen to others speak, and then in how I am able to consider my response to a greater extent), as part of the chronic effect that may be reducing a subconscious amount of anxiety in how I perceive the world in general. I will attempt to continue to monitor this perceived effect specifically.
I'm going to keep taking the mag threonate consistently, and I'll report back if its effect on generalized anxiety seems to improve further with time. Currently, I take it roughly every other day. This is the schedule that allows me to stay ahead of any cumulative sedating effect that the mag threonate has.

Magnesium supplement enhances spatial-context pattern separation and prevents fear overgeneralization
Enhancement of pattern separation could be helpful in improving the quality of normal daily learning and in treating individuals with cognitive impairment and certain psychiatric disorders. Previously, we have shown that elevating brain magnesium, by a novel magnesium compound (magnesium-L-threonate; MgT), enhances extinction of fear memory without enhancing amygdala-dependent fear memory. Here, we investigated the effects of MgT treatment on contextual-fear memory and subsequent pattern separation. Sprague–Dawley male rats were treated with MgT for 4 weeks and memory was evaluated using a spatial-context fear conditioning task. The pattern separation ability of MgT-treated rats was assessed using a spatial-context-discrimination task. MgT treatment did not enhance the retention of contextual-fear memory. Interestingly, the ability to discriminate between two, more or less distinct, contexts was enhanced in MgT-treated rats. Our results suggest that elevation of brain magnesium might be helpful in enhancing spatial-context discrimination and/or pattern separation besides preventing aversive-event-induced overgeneralization of fear.

Chronic dietary magnesium-L-threonate speeds extinction and reduces spontaneous recovery of a conditioned taste aversion
Elevation of brain magnesium enhances synaptic plasticity and extinction of conditioned fear memories. This experiment examined the generalizability of this phenomenon by studying the effects of a novel magnesium compound, magnesium-L-threonate (MgT), on conditioned taste aversion (CTA) extinction and spontaneous recovery (SR). Adult male Sprague–Dawley rats were maintained on a 23-hour water deprivation cycle and acquired a CTA following the taste of a CS [0.3% saccharin + 16 mg/ml MgT (SAC + MgT)] paired with a US [81 mg/kg (i.p.) lithium chloride (LiCl)]. Following CTA acquisition, rats drank a water + MgT solution for up to 1 hour/day over the next 31 days. For 14 additional days, some animals continued water + MgT treatment, but others drank water only to allow MgT to be eliminated from the body. We then employed 2 different extinction paradigms: (1) CS-Only (CSO), in which SAC was presented, every-other day, or (2) Explicitly Unpaired (EU), in which both SAC and LiCl were presented, but on alternate days. EU extinction procedures have been shown to speed CTA extinction and reduce spontaneous recovery of the aversion. Throughout extinction, half of the rats in each group continued to drink MgT (now in SAC or supplemental water + MgT solution), whereas the other half drank SAC only/water only until SAC drinking reached ≥ 90% of baseline (asymptotic extinction). Rats receiving MgT just before/during extinction drank less SAC on the first day of extinction suggesting that they had retained a stronger CTA. MgT enhanced the rate of extinction. Furthermore, the MgT-treated rats showed a relatively modest SR of the CTA 30 days later — indicating that the extinction procedure was more effective for these animals. Our data suggest that long-term dietary MgT may enhance the consolidation/retention of a CTA, speed extinction, and inhibit SR of this learned aversion
