Life Extension Neuro-Mag L-Threonate (Tropical Punch) Powder with Ultra-Absorbable Magnesium, Memory, Focus & Overall Cognitive Performance Boost - Non-GMO, Gluten-Free - 3.293 oz (30 Servings)

As you can see from the pictures, taken just after unpacking, the pot arrived very nearly empty. Although the pot came with a seal round the edge, we didn't dare use it as we thought it must not be a genuine product to be so empty. Intensely frustrating as we've used other life extension products in the past and found them not bad but we've never had a product arrive with half the product missing.

Not buying again, it has Maltodextrin in it. Ialso the tub was only a quarter full

The tub is on the larger side but does contain the right amount of magnesium. I found the flavour pleasant having had liquid magnesium before that had a metallic taste. I mix this in a water bottle and drink over an hour or two. Happy with the product and will check any improvements over the coming days and weeks.

Ich verstehe nicht wie mein "Vorredner" nur einen Stern geben kann und sich darüber aufregt, dass es sich um Pulver handelt... Das hat der Anbieter doch deutlich angegeben. Natürlich ist es Pulver und genau darum geht es auch. Es ist deutlich günstiger als in verkapselter Form.Mein "Vorredner" fragt außerdem, ob man es durch die Nase ziehen soll und dass er nicht weiß, wie es zu dosieren ist.Zum ersten: Wenn man Spaß dran hat, kann man das schon durch die Nase ziehen. Ist halt trotzdem Schwachsinn.Zum zweiten: Die Dosis ist gut verständlich auf der Packung erklärt und kann mit Hilfe des beigelegten Löffels auch gut dosiert werden. (Für eine genauere Dosierung kann man eine Feinwaage verwenden. Gibts schon für 20 € auf Amazon.)Die Wirkung ist sehr gut und geschmacklich finde ich es auch ansprechend. Alles in allem kann ich das Produkt sehr empfehlen, da man hier viel Magnesium L-Threonat für einen vernünftigen Preis bekommt.Nach ein paar Tagen der Anwendung (ca 5-7 Tage) spüre ich eine deutliche Konzentrationssteigerung, Verbesserung der Merkfähigkeit, Kopfrechnen, Denkprozesse etc. laufen schneller. Meine Gedächtnisleistung ist allgemein verbessert. Allerdings muss man es einige Tage hintereinander nehmen, um diesen Effekt zu erzielen.Was man außerdem wissen sollte: Magnesium L-Threonat ist die einzige Form von Magnesium, die den Magnesiumspiegel im Hirn effizient erhöhen kann und eine sehr gute Bioverfügbarkeit hat. Es wurde patentiert (Magtein™) und ist daher leider so teuer.Es kann auch das Kurzzeitgedächtnis verbessern, was das Ergebnis dieser Studie war (https://www.ncbi.nlm.nih.gov/m/pubmed/24077207/).Hier noch einige interessante Studien über die Vorteile von Magnesium L-Threonat:ConclusionsOur results suggest that elevation of brain magnesium exerts substantial synaptoprotective effects in a mouse model of Alzheimer’s disease, and hence it might have therapeutic potential for treating Alzheimer’s disease. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4172865)ConclusionWhile the standard of care for people suffering from clinical depression has not changed significantly since the introduction of SSRIs and SNRIs decades ago, current research has explored novel paradigms with the potential to develop new treatments to address the unmet need in depression patients. [...] While ongoing developmental research aims to develop optimal antagonists and allosteric inhibitors of the glutamatergic pathway, other work is exploring magnesium homeostasis in the brain: magnesium levels modulate glutamatergic activity, and low brain magnesium levels correspond to animal models of depression, while high levels increase synaptogenesis and synaptic plasticity. The synthesis of research exploring how modifying these systems changes the structure and function of neurons and pathways with development of treatments targeting these pathways offers hope for improving the speed of response, remission, and quality of life for patients suffering from depression. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3936783/)SummaryLearning and memory are fundamental brain functions affected by dietary and environmental factors. Here, we show that increasing brain magnesium using a newly developed magnesium compound (magnesium-L-threonate, MgT) leads to the enhancement of learning abilities, working memory, and short- and long-term memory in rats. The pattern completion ability was also improved in aged rats. MgT-treated rats had higher density of synaptophysin-/synaptobrevin-positive puncta in DG and CA1 subregions of hippocampus that were correlated with memory improvement. Functionally, magnesium increased the number of functional presynaptic release sites, while it reduced their release probability. The resultant synaptic reconfiguration enabled selective enhancement of synaptic transmission for burst inputs. Coupled with concurrent upregulation of NR2B-containing NMDA receptors and its downstream signaling, synaptic plasticity induced by correlated inputs was enhanced. Our findings suggest that an increase in brain magnesium enhances both short-term synaptic facilitation and long-term potentiation and improves learning and memory functions.(https://www.cell.com/neuron/fulltext/S0896-6273(09)01044-7?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0896627309010447%3Fshowall%3Dtrue)

I have had to stop buying it though because of the wasteful, unnecessary use of plastic. Please change packaging so I can start purchasing it again.
