What Is In Booster XT? The Six Ingredients On The Label

The ingredients list is short and easy to copy. The harder part is knowing what the label leaves out. This page gives the list first and the gaps right after it.
Six actives are named on the Booster XT label: grape skin extract, maca root extract, velvet bean seed extract, pine bark extract, L-carnitine and L-citrulline. The label prints no amount for any of them, no blend total and no standardisation. So no one outside the maker can say how much of each a capsule holds.
- Actives named: six, listed below.
- Amounts printed: none for any ingredient, and no proprietary blend total.
- Also not published: standardisation ratios for the botanical extracts, the carnitine salt, the levodopa content of velvet bean and the capsule shell material.
- Form: 30 capsules per bottle, dietary supplement.
- Seals: GMO-free, gluten-free, dairy-free, vegetarian, natural-ingredient and doctor-formulated marks are manufacturer statements.
- Third-party testing: no independent certificate is published.
- Comparison: a single-ingredient product with a stated amount per serving is easier to check.
What are the six ingredients in Booster XT?
The named list is below, in the order we hold it. Each is an active, and each is listed without an amount.
| Ingredient | Typical dose used in trials | Amount in Booster XT | Best evidence we cite |
|---|---|---|---|
| L-Citrulline | 3-8 g daily | Not published | Blood pressure meta-analysis (Mirenayat 2018) |
| L-Carnitine | 2-3 g daily | Not published | Male fertility review (Khaw 2020) |
| Pine Bark extract (Pinus pinaster) | 50-360 mg standardised | Not published | Cochrane review (Robertson 2020), unfavourable |
| Velvet Bean (Mucuna pruriens) seed extract | 15-30 g seed powder | Not published | Parkinson's trial (Katzenschlager 2004) |
| Maca root extract (Lepidium meyenii) | 1.5-3 g daily | Not published | Systematic review (Shin 2010) |
| Grape skin extract (Vitis vinifera) | Stated in every trial | Not published | Men's trial (Barona 2012) |
Read the third column twice. The trial figures in column two come from studies of single ingredients. They are not what is in the capsule. The finished product has never been tested as a product.
What does the Booster XT label leave out?
Quite a lot, and it is worth listing, because a list of gaps is more useful than a list of hopes.
- Every amount. Not a milligram figure for any of the six.
- A blend total. Some labels hide amounts inside a proprietary blend but still print the total. This one prints neither.
- Standardisation. Botanical extracts vary in strength, and the ratios for the two plant extracts are not published.
- The carnitine salt. Which form of carnitine is used is not stated.
- The capsule shell material.
- The levodopa content of the velvet bean material.
Our page on reading a label with no numbers explains how to think about that gap.
What is each ingredient best known for?
In one line each, and only from what our sources say.
L-citrulline is studied for blood pressure. The same research notes it lowers blood pressure slightly, which matters if you take medicine for it. Our page on citrulline and the doses used in trials has more.
L-carnitine is covered by a male fertility review in our sources, and its reported side effects are stomach upset and loose stools.
Pine bark extract has a Cochrane review that our sources describe as unfavourable. See maca, pine bark and the evidence gap.
Velvet bean is a natural source of levodopa, the molecule prescribed for Parkinson's disease. It is the ingredient that carries real medicine interactions. Our page on velvet bean and your medication covers that.
Maca root has a systematic review in our sources. The most cited maca trial checked for a testosterone effect and found none.
Grape skin extract is covered by a men's trial. Grape polyphenols can lower blood pressure slightly.
What do the seals on the bottle actually mean?
The label carries GMO-free, gluten-free, dairy-free, vegetarian and natural-ingredient marks. It also carries a doctor-formulated mark, a made-in-the-USA mark and mentions of FDA-registered and GMP-operated manufacturing.
All of those are manufacturer statements. None is an independent certification. The doctor-formulated mark names no clinician and publishes no credential. And FDA-registered is not FDA-approved. No dietary supplement is FDA-approved.
What is Booster XT claimed to support?
This website carries four structure-and-function lines only: circulation support, everyday energy, physical performance and recovery, and antioxidant support.
Some wording on the manufacturer's own listing artwork goes further, with lines about hormones, inflammation, fat and dopamine. We do not carry those lines, because the label does not back them. We also carry nothing about treating a sexual or medical condition.
These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.
How does a label like this compare with other products?
Many other products print an amount per serving, and some add a third-party mark. This label does neither. That is a real difference, and we say so openly.
If a known dose of a known ingredient is what you want, a single-ingredient product with a stated amount per serving is easier to check. If you would rather take one capsule a day and judge it by how you feel, with 60 days to change your mind, this is the product built for that.
Who should read the ingredient list with a doctor?
Men on levodopa, MAO inhibitors, antipsychotics or dopamine agonists. Velvet bean is the reason, and the missing amount makes it worse.
Men on blood pressure treatment, nitrates or PDE5 drugs, since citrulline and grape polyphenols both nudge pressure down. Mention an anticoagulant or thyroid treatment too. Our guide on blood pressure medicine and Booster XT has the detail.

Frequently asked questions
What is in Booster XT?
Six named actives: grape skin extract, maca root extract, velvet bean seed extract, pine bark extract, L-carnitine and L-citrulline.
How much of each ingredient is in a capsule?
Not published. The label prints no amount for any ingredient and no blend total.
Does Booster XT contain a proprietary blend?
The label prints no blend total and no amounts. We describe the amounts as not published rather than guess.
Is velvet bean in Booster XT a drug?
It is a plant extract, but the seed is a natural source of levodopa, which is prescribed for Parkinson's disease. The amount is not published.
Are the seals on the label independent certifications?
No. The GMO-free, gluten-free, dairy-free, vegetarian, natural-ingredient and doctor-formulated marks are manufacturer statements.
Has Booster XT been tested as a finished product?
No. The research cited concerns the individual ingredients, usually at amounts the label does not print.
Our view
The list is simple, the research on single ingredients is easy to find, and the label gives you almost nothing to connect the two. That is the honest centre of this page.
We would like to see amounts printed and a third-party certificate published. Until then, any claim that a capsule does what a trial dose does is a leap. We have tried not to make it.
If you take medicine, read the list with your doctor. If you do not, the 60-day window gives you a way to test the capsule on yourself.
