CORE Rebuild 9 gives your muscles all nine essential amino acids — the building materials used in muscle protein synthesis, repair and recovery. Essential means your body cannot make them. They have to come from what you eat or what you take.
These are free-form amino acids, already broken down. No whole protein to digest, no volume to get through, no meal to force on a day when eating feels like work.
Five small tablets per serving. No blender, no scoop, no sweetener, no flavour to choke down. 150 tablets is one full month.
100% vegan, gluten-free, soy-free, dairy-free, sugar-free, non-GMO. Produced in an FDA-registered, cGMP-certified facility.
You start. You fade halfway through. You're wrecked for a day or two afterward, so the next session quietly disappears. Then you start again from zero and call yourself inconsistent.
That's the Workout Drain Loop, and it isn't a discipline problem. It's a sequence problem. Energy is what gets you through the session. Recovery is what determines whether you come back for the next one. When recovery stretches, consistency collapses — and consistency is the only thing that actually rebuilds muscle.
Here's the part nobody explains: the workout itself doesn't build anything. It's only the signal. Resistance training tells your body to rebuild. What it rebuilds with is amino acids — and if the materials aren't there, the signal goes out and nothing answers it.
CORE Rebuild 9 supplies all nine essential amino acids in free form, so the materials are there when your body asks for them. More support through the session. Better support after it. And training that finally accumulates instead of resetting every week.
All nine essential amino acids — not three, not a partial blend. BCAAs alone cover three of the nine. Collagen isn't a complete protein for muscle rebuilding. Your body needs the full set.
| L-Leucine, L-Valine, L-Isoleucine | The three BCAAs. Leucine is the primary trigger for muscle protein synthesis — the switch that tells your body to build rather than break down. These are the three most supplements stop at. |
| L-Lysine HCl | Used in collagen formation and tissue repair. Many diets run quietly short on this one, including higher-protein diets. |
| L-Threonine | Involved in collagen and elastin production — the connective tissue that holds posture and joints together while you rebuild strength. |
| L-Methionine | A sulfur-bearing amino acid used in tissue growth and normal metabolic function. Difficult to get enough of without animal protein. |
| L-Histidine | Used in tissue repair and growth, and in the formation of carnosine in muscle. |
| L-Phenylalanine | An essential amino acid used as a building block for protein throughout the body. |
| L-Tryptophan | The ninth essential amino acid. Required to complete the set your body uses for protein synthesis. |
| Nucleic acid building blocks | Uridine, adenosine triphosphate, thymidine, adenine and deoxynucleosides — components most protein sources do not contain at all, used in normal cellular energy production and cell renewal. |

Take 5 tablets daily with water. The tablets are small and smooth. Most women take theirs with breakfast, or about half an hour before activity on the days they train.
No mixing, no measuring, no forcing food down before you're hungry. They travel — handbag, desk drawer, car — which matters on the days when a proper meal isn't going to happen.
CORE works alongside resistance activity and adequate protein, not instead of them. The workout is the signal; these are the materials.
CORE Rebuild 9 is a food-based supplement of essential amino acids. It is not a hormone, not a stimulant, and it is not designed to change how your medication works.
Keep taking your medication exactly as your prescriber directs. Thyroid medication is usually taken on an empty stomach, separated from food and supplements — so most women take their medication first thing and their CORE serving later, with breakfast or before activity.
We are not able to give you medical advice, and we would rather say so than guess. Before starting any new supplement, check with the prescriber or pharmacist who knows your medication, your dose and your history. Bring the label — it's in the product images above, and we're happy to email the full Supplement Facts panel if that's easier.
Yes. Every order is backed by our 120-day money-back guarantee.
You've bought things before that promised a great deal and did nothing, so we'll be plain about this: rebuilding is gradual, and four months is long enough to actually find out. Take it consistently, keep training, and see what changes.
If it isn't for you, contact us within 120 days and we'll refund every penny. No questions asked, and no subscription you have to fight to cancel.
Real Women. Real Rebuilding
What they noticed, in the order they noticed it
"I ordered this expecting nothing." It was the fourth thing I had tried since my diagnosis. Two weeks in, honestly, nothing. Then I got through a full walk without needing to sit down afterward, and I realised that had not happened in about two years.
"The day after used to cost me everything." I would do twenty minutes and lose the whole next day to the couch. It still takes something out of me, but now it costs me an afternoon instead of a weekend. That difference is the whole thing.
"Three weeks in a row." I used to start, crash, quit, then start over a month later and call myself lazy for it. I am not doing anything heroic. I am just actually showing up, which turns out to be the part I could never get to before.
"I carried both bags up the stairs and did not stop halfway." That sounds like nothing. If you have been where I have been, you know it is not nothing. My legs feel like they belong to me again and my posture in photos has changed.
"I was already taking enough pills, so five more was my hesitation." They are small and they go down with my morning water in about ten seconds. Compared with the shake I used to force down at breakfast, this is not even a decision.
"I had tried BCAAs and felt absolutely nothing, so I assumed this was the same thing." It is not. Three amino acids is not nine. Nobody explained that to me in two years of reading about this, and it turned out to be the part that mattered.

Energy first. Then recovery.
Then the strength to show for it.
Rebuilding does not happen all at once, and it does not start with the thing you are actually after. It starts with having a little more in the tank. Here is what women told us they noticed, in the order they noticed it.
More In The Tank
Had more physical energy during activity and faded less halfway through
Less Wreckage
Felt less depleted the day after activity than they did before starting
Back Sooner
Were training more consistently than they had been in the year before
Would Recommend
Would recommend CORE to a friend managing a thyroid condition

When You Stay Consistent
What Rebuilding
Actually Looks Like
When You Stay Consistent
We would rather tell you the truth than sell you a miracle. This is gradual, it starts smaller than you want it to, and the rungs arrive in a particular order.
You will probably not feel anything, and that is normal. Five tablets with water. Free form amino acids do not need whole protein digestion, so the materials are available quickly. Whether your body has anything to do with them depends on what you ask of it.*
The first rung is energy, and it is quieter than you expect. Not a jolt. Most women describe it as fading less halfway through, or finishing a walk without needing to sit down straight after. Small, but it is the rung everything else stands on.*
The day after starts costing less. Activity still takes something out of you. It just stops taking the whole next day with it. This is the rung that decides everything, because the next session is what you have been losing.*
You stop starting over. Two sessions a week, three weeks running. Nothing heroic. But training has finally begun to accumulate instead of resetting, and accumulation is the only thing that has ever rebuilt muscle.*
Strength shows up in ordinary places first. Stairs, groceries, getting up off the floor, how you stand in photographs. Weeks of accumulated training supported by all nine essential amino acids is what makes this rung possible.*
Rebuilding stops feeling like a project. Energy, recovery and training are running on a supported daily foundation, and the woman who could not string two weeks together is not who you are anymore. Most women at this point simply keep going.*
*Timings are typical of what customers report and are not a promise. Individual results vary. CORE supports the muscle nutrition side of rebuilding alongside your medical care, adequate protein and resistance activity. It is not a treatment for any thyroid condition.
