THE SLOW CHANGE
No single moment you could point to. Just a day that asks a little more of you than it used to.
Eight hours of sleep, and you wake up as if it were five.
The second coffee stopped being a treat. It’s the plan now.
The afternoon wall arrives on schedule. You’ve started planning around it.
An invitation for tonight. You say no before you’ve checked how you feel.
Yesterday is still in your legs. Recovery that took a night now takes two.
They don’t feel connected. They have more in common than they seem.
Each one draws on the same resource: how much energy your cells can produce, hour after hour. That production depends on a molecule your body makes less of every year from your late thirties.
It isn’t a lack of effort. It’s a shortfall in supply.
THE MOLECULE BEHIND ITAlpha-ketoglutarate is a molecule your body makes on its own, a central node in the reaction that turns food into cellular energy. In youth it is plentiful and the systems that depend on it run without a shortfall.
Production falls with age. By the time the decline is felt, it has been underway for years. These dots stand for the AKG your body produces. Watch what changes from 35 to 60+.
AKG occurs in food in trace amounts. There is no diet that closes this gap.
Alpha-ketoglutarate sits at the centre of the Krebs cycle, where food becomes the energy your cells run on. Replacing it is not a matter of simply swallowing it. It has a plasma half-life measured in minutes, so most of a standard dose is gone before it reaches the tissue that needs it.
PureAKG is built around that single problem. Calcium-bound for stability and released across hours rather than minutes, it reaches your cells as a steady supply at a concentration they can actually use.
One molecule
Aging isn't one problem. It's several systems slowing together, and all of them run on the same molecule. Some changes you notice within weeks. Others build quietly for years.
Felt in weeks
No afternoon wall and no stimulant. AKG feeds the cycle your cells make energy from.
The day after a long walk or a hard session stops costing you two.
The cells lining your gut burn AKG as their preferred fuel.
Built over months
Grip strength and lean muscle hold longer when the supply of AKG is maintained.
Your skeleton rebuilds itself every day and AKG is one of its building blocks. Bone density decides whether a fall is a bruise or a break.
Not just a longer life. More of it spent strong, sharp and independent, doing what you want without asking for help.
Two clocks, one body
One clock counts your birthdays. The other is written into your cells, and it can be measured. Set your age and see what seven months could do.
Your biological age at month 7
Month 7 · The milestone. Think back to who you were at 42. That's the age your cells read now, while your passport still says 50.

Without it, both clocks climb together.
Based on published research on calcium alpha-ketoglutarate measuring an average 8 year reduction after 7 months of use. Individual results vary.
We work with gerontologists, clinicians and longevity researchers who hold this field to a standard most supplements are not built to meet. Their scrutiny shaped the formula. Here is how they think about it.
“We tested many promising compounds for healthy aging. The result was clear. Calcium alpha-ketoglutarate, delivered properly and paired with the right cofactors, was the most effective at increasing healthspan and lowering biological age.
Co-Director, Centre for Healthy Longevity, NUHS, National University of Singapore
“The interesting question with alpha-ketoglutarate was never whether the molecule matters. The biochemistry settled that decades ago. It was whether you could get a meaningful amount of it to the tissue. That is a formulation problem and it is the one worth paying attention to.
DC, MS, BCHH, Founder, Human Longevity Institute
“Patients arrive at fifty having done everything they were told to do and still feeling the change. What I want for them is something with a clear mechanism and an honest evidence base rather than a promise. Alpha-ketoglutarate has a defined role in cellular metabolism and that is a reasonable place to start a conversation.
MD, FACP, FACPM, DABIHM, CTH, Clinical Instructor of Medicine, Adelaide Hospital
“Most of what reaches consumers in this category is a molecule in a capsule with no thought given to delivery. Purity verification and controlled release are not marketing features. They are the difference between a supplement that does something and one that does not.
CEO, OptiHealth Inc., Affiliate Professor of Oral Health Sciences, University of Washington
Alpha-ketoglutarate doesn't announce itself. It works at the level of the cell and the effects surface in order. The quick ones first. The structural ones in months.
Quiet work begins
The first dose is already feeding your cells’ energy cycle. Nothing to feel yet, and no jolt to come down from.
Krebs cycle
What you notice first
Three o’clock comes and goes. Energy feels even rather than boosted.
ATP supplyConcentration lasts through the last meeting of the day.
Neuronal energy
Your body catches up
The heavy, sluggish feeling after lunch becomes the exception.
Enterocyte fuelA long walk or a hard session no longer lingers into the next day.
Muscle regeneration
The studied duration
The instructions your cells read stay clearer. This is the shift the published research measured.
DNA methylation · TET enzymesSteady supply has had months to reach muscle and bone, where change is slow but lasting.
Collagen synthesis
The compound effect
Frailty is built from a thousand small declines. Steady supply is a daily decision against them.
HealthspanThe invitations, the trips, the long weekends. You stop checking whether you’re up to it.
Hallmarks of agingThe first changes take weeks. The deepest take months. Choose a course long enough to reach them.
Choose your durationTwo tablets, once a day. Engineered to release across twelve hours so cellular supply stays constant.
BEFORE YOU CHOOSE
Same molecule. The dose, the form and the release decide what reaches your cells.

Read the refund policy →I went in expecting to disprove it and tracked everything for six months.
I do not have a dramatic story. I have a set of numbers that moved in the right direction and stayed there, and at my age that is worth considerably more than a dramatic story.
It creeps up on you, which I suspect is the point.
Nothing happened in week one. By week eight I realised I had stopped thinking about my energy at all, and not thinking about it turns out to be the whole thing I was trying to buy.
I read the literature before I read the label, which is my habit and usually the end of it.
The mechanism held up. Six weeks in, my concentration through the back half of the day is measurably better and there is no crash attached to it, because there was never a stimulant to crash from.
I stopped needing the second coffee.
That was the first thing. Not a surge of energy, just the absence of the wall I had been hitting at three o’clock every afternoon. Ten days in and I only noticed because it had already stopped happening.
I train five days a week and I am forty-five, and the maths on that had started to catch up with me.
The change was not in the sessions. It was the day after. I stopped needing it. I am holding a schedule now that I was quietly planning to scale back.
Twelve years of trying things.
What is different here is that I can point at what changed. I sleep through, and I wake up without the twenty minutes it used to take to become a person. It is not dramatic. It is just consistent, which is more than I can say for anything else I have taken.
I run three-hour board meetings.
By the last hour I used to be managing my own attention as hard as I was managing the room. That is gone. It is the single most valuable thing this has done for me and it is difficult to overstate.
At three months my sister asked what I had changed.
That was the moment. Not the mirror, my sister. My skin looks better than it did two years ago and I have the energy to match it, which is the part I had not expected.
Three children and a business.
My problem was never getting started, it was still being useful at six in the evening. I get to the end of the day now with something left, and that has changed what my evenings look like.
I am fifty-three and I ride with a club where I am the oldest by a decade.
Six months ago I sat at the back of that group. On Sunday I was pulling on the climb. I do not have a better explanation than the obvious one.

PureAKG is our patented form of calcium alpha-ketoglutarate, over 99% pure and delivered via controlled-release for maximum small-intestine absorption. It is the active ingredient behind the biological age reductions documented in published human clinical studies.
AKG works at the level of the cell, so the first changes are subtle. Most people report steadier energy and clearer focus within the first two to four weeks. The measurable reduction in biological age documented in published research appeared after an average of seven months of continuous daily use.
Write to us within 60 days and we will refund the order in full. Cellular change is not felt in a week, and we would rather you took the full two months than sent it back after ten days.
Calcium alpha-ketoglutarate has no known negative interactions with common supplements. If you take prescription medication or manage a health condition, speak to your physician before starting. That applies to any new supplement rather than to this one in particular.
Three decisions. The calcium-bound form survives the stomach and arrives intact. The controlled-release matrix meters it across hours rather than minutes, which matters because alpha-ketoglutarate has a plasma half-life measured in minutes. And it is formulated with the cofactors those enzyme pathways depend on. The molecule is the easy part. These three decisions are what determine whether it reaches the cell.
Orders are processed within 24 hours, at which point your tracking number is sent to you by email. Delivery takes up to seven days from that point. You will be able to follow the parcel for the whole of that time.
Write to us at Info@pureakg.org or call +44 7460 042062, Monday to Friday, 9:00 to 17:00 UK time. We typically respond within 24 hours.
Two tablets once daily, with or without food. The controlled-release matrix meters the dose across the day, so consistency matters more than timing. Whichever time you are most likely to remember is the right one.
Yes. Alpha-ketoglutarate is consumed continuously and your own production keeps declining with age. Stopping returns you to your baseline supply over a matter of weeks. This is replacement rather than a course of treatment.
Calcium alpha-ketoglutarate (1000 mg per serving, 2 capsules daily), plus small amounts of microcrystalline cellulose and maltodextrin to form the capsule. One active ingredient at a meaningful dose, rather than a long label. No stimulants, no proprietary blends, no artificial colours.
Every batch is assayed by an independent laboratory for identity, potency and contamination before release. The certificate of analysis for the batch number printed on your bottle is available on request.
Calcium alpha-ketoglutarate has been established as safe at higher intakes across multiple published studies. There is no evidence that exceeding the recommended dose improves the outcome, and the research this product is built on used a single daily dose. Consistency across months is what the data supports.
