Magnesium L-threonate
Time-released Micropills
L-threonate is the only form of magnesium clinically shown to support memory, focus, and cognitive performance. Developed at MIT and backed by five clinical trials.
Day Stack™ delivers it in pharmaceutical-grade, timed-release micropills. Take Day Stack at 9am and the L-threonate releases from 1pm to 6pm, keeping you calm, clear, and present through the afternoon.
L-threonate is one of 20 vitamins and minerals in Day Stack, all releasing in two phases over 9 hours. Nutrients that work together are paired. Nutrients that compete are separated. One capsule handles your entire day.
Four Week Supply: 28 Day Stacks
Each Day Stack™ contains around 2,000 micropills that release in two phases over 9 hours. Nutrients that work better together, like Iron and Vitamin C, are paired. Nutrients that block each other, like Calcium and Magnesium, are separated.
Traditional multivitamins dump everything into your stomach at once. Day Stack uses precision timing, so your body actually absorbs what you take.
Every ingredient in Day Stack™ meets 99%+ pharmaceutical-grade purity standards, far exceeding the roughly 80% purity typical of food-grade supplements. Higher purity means higher absorption and fewer unknowns.
Our facilities are certified to Japanese and Swedish standards, two of the strictest in the world. What's on the label is what's in the capsule.
Every component of Day Stack™ is 100% recyclable. To safeguard against environmental impact, for every gram of medical-grade plastic we produce, we fund the reclamation of two grams of plastic that would otherwise enter our planet’s oceans.
Born at MIT. Built for Your Brain.
MIT researchers solved the problem that makes most magnesium supplements ineffective for cognitive performance.
The Problem
Magnesium is essential for learning, memory, and synaptic function. But standard magnesium supplements have a fundamental limitation: they support your muscles and body, but very little reaches the brain where cognitive performance actually happens.
The Search
Dr. Guosong Liu and his team at MIT screened thousands of magnesium compounds looking for one that could effectively support cognitive function. A single compound delivered: Magnesium L-threonate.
The Breakthrough
Their findings were published in Neuron1, one of the most prestigious neuroscience journals in the world, with Nobel laureate Susumu Tonegawa on the author list. The paper demonstrated that L-threonate enhanced learning, working memory, and both short-term and long-term memory.
Why Most Magnesium Falls Short
Standard magnesium supplements support your muscles and body, but they were never designed for cognitive performance. L-threonate was.
What Makes L-threonate Different
L-threonic acid is a natural metabolite of vitamin C already recognized by your body. It acts as a carrier, delivering magnesium to where it can support cognitive function, using transport pathways that other forms of magnesium simply cannot access.
The result: enhanced signaling between neurons, increased synaptic density, and elevated BDNF, a protein critical for the growth of new neural connections. This is why L-threonate improves memory and focus in clinical trials while other magnesium forms do not.

How Magnesium L-threonate Works
From delivery to results, here is what happens after you take it.
Reaches Where It Matters
L-threonic acid is a natural vitamin C metabolite your body already recognizes. It carries magnesium to where it can support cognitive function, something other forms of magnesium cannot do.
Sharpens Neural Signaling
Magnesium regulates the NMDA receptor, a critical gatekeeper for learning and memory. L-threonate ensures these receptors are properly tuned, supporting clearer thinking and faster processing.
Builds Stronger Connections
L-threonate increases synaptic density and upregulates BDNF, a growth factor for new neural connections. More connections means more capacity for learning and recall.
Makes Learning Stick
Long-term potentiation is how your brain turns experiences into lasting memories. L-threonate enhances this process, making it easier to encode and retain new information.
The net effect: sharper recall, faster processing, and stronger learning capacity. L-threonate does not just provide magnesium. It provides it in the form that actually improves cognitive performance.
What You Can Expect
L-threonate does not just provide magnesium. It provides the form that actually supports cognitive performance, backed by clinical trials.
Memory and Learning
Clinically shown to enhance working memory, short-term memory, and long-term memory. Participants in trials showed measurable improvements in recall within weeks.
Focus and Mental Clarity
Supports sustained mental clarity by increasing BDNF, a growth factor for new neural connections. Trial participants showed faster reaction times and sharper processing.
Sleep Quality
Clinical trials show improved mood upon waking, reduced morning grogginess, and better mental alertness, even at lower doses.
Anxiety and Stress Response
Supports a healthier stress response by helping your body process and release tension more effectively, without the sedation of traditional calming supplements.
Neural Connectivity
Increases the number and quality of synaptic connections, strengthening the infrastructure that supports learning, creativity, and cognitive flexibility.
Neuroprotection
Supports long-term cognitive health. Research shows L-threonate helps maintain synaptic connections and promotes the growth of new neurons as you age.
