Does Booster XT Have a Proprietary Blend? Checking the 570 mg Formula Claim

Some searches pair the name with a figure of 570 mg. Others ask about a proprietary blend. Both questions come down to one thing: what number, if any, is printed on the label. This page checks each against what the label and the paperwork say.
No. The label names six actives and prints no amount for any of them. It also prints no blend total, so there is no proprietary blend figure to quote, and a 570 mg daily formula cannot be confirmed from the label. Treat any such number as unverified until a readable panel shows it.
Key facts
- Actives named: L-citrulline, L-carnitine, pine bark extract, velvet bean seed extract, maca root extract and grape skin extract.
- Amounts: not published for any of the six.
- Blend total: not published either, which is rarer than a blend and gives no ceiling to work from.
- Also unpublished: standardisation ratios for the two plant extracts, the levodopa content of the velvet bean material, the carnitine salt and the capsule shell material.
- Serving: one capsule a day is implied by the kit ladder, with no separate serving size printed in the material we hold.
- Form: 30 capsules per bottle, a dietary supplement and not a drug.
What is a proprietary blend, and why does it matter?
A proprietary blend is a list of ingredient names with one total weight beside them. You learn that the whole mix weighs a certain amount, but not how much of each ingredient is inside. The maker keeps the split private.
That is not ideal, yet it still gives you something. The total is a ceiling. No single ingredient can weigh more than the blend does, so some of the biggest claims can be ruled out with simple sums.
Does Booster XT print a blend total?
No. The panel names six actives, and it prints neither a figure for each nor a total for all of them together. That is rarer than a blend, and in one way it is worse, because without a total there is no ceiling to work from.
In one way it is slightly better. The six names are printed one by one, and not tucked under a trademarked blend name. So you can look each ingredient up for yourself, which is what the ingredients page does.
Whatever the label does or does not print, every study cited on this site is about an ingredient on its own. None of it measures this capsule.
Where does a 570 mg figure come from?
We cannot say. Nothing in the label text or the paperwork this site holds gives a total of 570 mg, or any other total, for a daily serving. A number like that may come from an advert, a reseller or a guess, and it cannot be checked from here.
A useful rule applies to any figure you meet online. A real amount sits on a Supplement Facts panel that you can read on the bottle or in a clear photograph of it. If a page quotes a number and shows no panel, ask the seller for a picture of the panel before you trust it.
The phrase daily formula adds a second puzzle. The kit ladder of 30, 90 and 180 days points to one capsule a day, but no separate serving size is printed in the material we hold. So even the words daily formula lean on an inference, not a printed line.
What does the Booster XT supplement facts list show?
Here is the full named list, with the gaps printed beside it. This site writes not published wherever a figure is missing, and it does not estimate.
| Item | Amount | What else is not published |
|---|---|---|
| L-citrulline | Not published | Nothing beyond the amount |
| L-carnitine | Not published | Which carnitine salt is used |
| Pine bark extract | Not published | The standardisation ratio |
| Velvet bean seed extract | Not published | The levodopa content of the material |
| Maca root extract | Not published | The standardisation ratio |
| Grape skin extract | Not published | Nothing beyond the amount |
| Capsule shell | Not published | What the shell is made of |
Notice that the missing velvet bean figure is a safety gap as well as a value gap. Velvet bean is a natural source of levodopa, so a clinician would want the amount to judge an interaction.
Can you work the amounts out from the capsule itself?
Only loosely. One capsule has a fixed physical size, and that caps everything inside it. Six active ingredients, plus the shell and any flow agent, have to share that space.
Set that beside the research. Trials of L-citrulline used 3 to 8 grams a day, and trials of L-carnitine used 2 to 3 grams a day. A capsule cannot carry grams of both, plus four plant extracts. So whatever is in a Booster XT capsule, it is very unlikely to match those trial amounts.
This is a reason to read the studies as background on each ingredient. It is not a reason to claim a particular number, and this site does not.
What should you ask the seller for?
Five documents would settle most of the open questions. This site has asked for them and will publish any of them the week it arrives.
- A readable photograph of the Supplement Facts panel.
- A milligram figure for each of the six actives.
- Standardisation ratios for the pine bark and grape skin extracts.
- The levodopa content of the velvet bean material.
- A third-party certificate of analysis for lot BXT-26/BD-8812.
Until any of those arrives, the honest position is to print not published and move on.
How do you decide when no numbers are printed?
You can still choose sensibly. You just cannot choose on the basis of dose.
- Cap your downside. The refund window is 60 days from purchase, and opened bottles are covered.
- Buy the smallest pack that fits that window.
- Check the interactions yourself, because the label does not list them.
- Set a date to judge it, and write down what would count as a result before you start.

Frequently asked questions
Does Booster XT have a proprietary blend?
Not in the usual sense. The label names six actives and prints no amount for any of them, and it prints no blend total either. So there is no blend figure to quote.
Is Booster XT a 570 mg formula?
That cannot be confirmed. No total of 570 mg appears in the label text or the paperwork this site holds. If you see the number elsewhere, ask the seller for a clear picture of the Supplement Facts panel.
Why does the label not print amounts?
We do not know the reason and will not invent one. The effect is the same either way: no claim that depends on the amounts can be checked.
Can I work out how much of each ingredient a capsule holds?
Only roughly. A capsule has a fixed size, so six ingredients share a small space. That makes full trial amounts very unlikely, but it gives no exact figure for any one ingredient.
What is the serving size?
No separate serving size is printed in the material we hold. The 30, 90 and 180-day kits imply one capsule a day, so follow the panel on the bottle you receive.
Has anyone asked the manufacturer for the amounts?
Yes. This site has asked for a readable panel, milligram figures, standardisation ratios, the levodopa content and a laboratory certificate. Any that arrive will be published.
Our view
Booster XT has no proprietary blend figure and no 570 mg figure that we can confirm. It has six names and no numbers. That is the single biggest limit on anything anyone can say about it.
If you can accept that, use the refund window as your safety net and judge it on your own notes. If you cannot, a single ingredient with a printed amount is the better fit.
