Core Nutritionals POST

A post-workout recovery formula from Core Nutritionals, a brand built on fully disclosed labels and clinical dosing.

⚠ The anabolic window is far wider than you were told

This is the most useful thing on the page, and it will probably save you money.

The "30-minute anabolic window" is largely a myth. For years the industry sold urgency — that if you did not get protein and carbohydrate in immediately after training, the session was wasted.

The research does not support that. The window for post-training nutrition is measured in hours rather than minutes, and what matters far more is your total daily protein and carbohydrate intake.

There is one genuine exception. If you trained fasted, or your last meal was many hours before, then nutrient timing after training matters considerably more — because you are starting from an empty state rather than topping up.

So who should buy a post-workout product?

Anyone training fasted, where the timing case is real
Anyone training twice a day, where the gap between sessions is short and glycogen replenishment genuinely matters
Endurance athletes with high glycogen turnover
Anyone who simply will not eat for a while after training, where a drink is better than nothing

If you eat a normal meal within a couple of hours of training, a dedicated post-workout product is largely optional. We would rather tell you that than sell you one.

What recovery actually requires

Three things, in order of how much they matter:

Protein. The material for repair. Roughly 1.6 to 2.2g per kg of bodyweight daily, with adequate leucine to trigger muscle protein synthesis
Carbohydrate. Refills muscle glycogen, which is what you actually depleted. More relevant the longer and more frequently you train
Fluid and electrolytes. You lost both in sweat, and rehydration affects how you feel for the rest of the day

What recovery does not require is urgency. Getting the daily totals right beats getting the timing perfect, by a wide margin.

Why Core Nutritionals is worth knowing

Core built its reputation on something specific: fully disclosed labels with no proprietary blends, and doses that match the research rather than the marketing.

That matters more than it sounds. A proprietary blend makes it impossible to check whether any single ingredient is at a meaningful amount — you see a combined total and have to take it on trust. Full disclosure is what makes an informed purchase possible at all.

It is the same reason we rate NutraBio and Centurion Labz — transparency is a genuine differentiator in a category where it is optional.

How to take it

After training, mixed with water.
Alongside a proper meal within a couple of hours — this supplements food rather than replacing it.
Most useful if you trained fasted, or have another session coming.
Stimulant-free, so it suits evening training.
Count it toward your daily protein and carbohydrate totals, which are what actually matter.

Who this is for

Anyone training fasted
People training twice a day
Endurance athletes with high glycogen turnover
Anyone who cannot eat properly for a while after training
People who want a fully disclosed label

Who this is not for

Anyone who eats a normal meal within a couple of hours of training. The window is far wider than the industry implies, and your daily totals matter more.

Anyone whose daily protein intake is not yet adequate. Fix that first — it is cheaper and it matters more than any timing strategy.

Anyone buying it out of urgency about the 30-minute window. That window is not real in the way it was sold.

Not for anyone under 18 without medical advice.

Stack it with: creatine daily, and adequate total protein — which is doing more than any post-workout formula.

Frequently asked questions

Is the anabolic window real?
Far wider than it was sold. Post-training nutrition is measured in hours rather than minutes, and total daily intake matters considerably more.

When does timing actually matter?
If you trained fasted, if your last meal was many hours earlier, or if you have another session within a few hours.

Do I need a post-workout product?
Not if you eat a normal meal within a couple of hours of training. It genuinely helps if you train fasted, train twice a day, or cannot eat for a while afterwards.

What matters most for recovery?
Total daily protein with adequate leucine, then carbohydrate to refill glycogen, then fluid and electrolytes. Urgency is not on the list.

Why does full label disclosure matter?
A proprietary blend makes it impossible to check whether any ingredient is at a meaningful dose — you see a combined total and take it on trust.

Can I take it in the evening?
Yes, it is stimulant-free.

Should it replace a meal?
No. It supplements food rather than replacing it.

How much protein do I need daily?
Roughly 1.6 to 2.2g per kilogram of bodyweight, spread across the day.
