The label
Booster XT ingredients and doses, exactly as printed
Booster XT publishes nine ingredient names, two of them with real numbers and seven of them inside a single 570 mg total. Below is the label transcribed, followed by the part of it that cannot be transcribed because the manufacturer does not print it.
| Ingredient | Amount per capsule | Why it is there |
|---|---|---|
| L-Citrulline | In the 570 mg blend | Nitric oxide precursor, listed first by weight |
| L-Carnitine | In the 570 mg blend | Fatty acid transport, studied for stamina |
| Pine Bark Extract (Pinus pinaster) | In the 570 mg blend | Procyanidins, endothelial support |
| Velvet Bean (Mucuna pruriens) seed extract | In the 570 mg blend | Natural L-dopa, dopamine precursor |
| Maca (Lepidium meyenii) root extract | In the 570 mg blend | Traditional libido support |
| Grape (Vitis vinifera) skin extract | In the 570 mg blend | Polyphenols, circulation support |
| Saffron (Crocus sativus) stigma extract | In the 570 mg blend | Mood and sexual function research |
| Vitamin B3 (niacin) | 20 mg, 125% DV | Normal energy metabolism |
| Zinc (as zinc oxide) | 11 mg, 100% DV | Normal testosterone maintenance |
| Proprietary Performance Blend, total | 570 mg | Combined weight of the seven actives above |
What we refuse to do with this label
Plenty of pages about this product print an invented milligram figure beside each botanical. There is no source for those numbers. The manufacturer publishes one total, 570 mg, and declines to publish the split. A proprietary blend is legal under US labelling rules and it is also the single biggest limitation of this formula, because it means nobody outside the production floor can say whether the L-citrulline dose is close to the multi-gram amounts used in the circulation literature or a fraction of it.[1] Our reviewers scored label transparency 4.02 out of 5, the lowest of the nine criteria on the Booster XT reviews page, and that score is the honest one.
What can be said is the ordering. US labelling rules require blend components to be listed in descending order of weight, so L-citrulline outweighs L-carnitine, which outweighs pine bark, and saffron carries the least of the seven. For a formula built on nitric oxide that ordering is at least the right way round.
Serving, timing and what to take it with
One capsule daily with water. The manufacturer does not specify morning or evening; most reviewers report taking it with breakfast, and the absence of stimulants means an evening dose does not cost anyone sleep. A bottle holds 30 capsules, which is a 30-day record at the labelled serving. There is no loading phase and no cycling instruction on the label.
The manufacturer asks for 3 to 4 weeks before judging anything and 4 to 8 weeks for the fuller picture, which is why the packages sold on the pricing page start at two bottles. A single bottle does not cover the window the label itself describes.
Allergens, form and what is not in it
Booster XT is a capsule, not a gummy, tablet or powder, so there is no added sugar, no sweetener and no flavouring. There is no caffeine, no yohimbine, no synephrine and no hormone of any kind in the formula. The label does not carry a vegan or vegetarian mark and does not declare a gluten-free status, so anyone who needs either confirmed should write to the desk before ordering rather than assume it.
Reading the two named nutrients
Zinc at 11 mg is the full daily value and sits far below the 40 mg upper limit for adults, which matters if you already take a multivitamin containing zinc; the two stack.[2] Vitamin B3 at 20 mg is above the daily value but far below the doses that cause the familiar niacin flush, so the reaction some people expect from high-dose niacin does not apply here.[3]
Neither nutrient is doing the heavy lifting in this formula. They are there to cover two common shortfalls in men over 40, and they are the two figures a buyer can actually verify.
Who this label suits and who it does not
It suits someone who wants circulation and libido support in one capsule, who is willing to give it six to eight weeks, and who can accept a proprietary blend. It does not suit anyone who buys by the milligram, anyone on nitrates or blood pressure medication without a doctor's sign-off, or anyone hoping a supplement will resolve a problem that started suddenly. For that last group the right next step is a physician, not a bottle.
The current run is lot BXT/26-R047 and the analysis summary is filed under MVL-26-4712 on the verification page. Pricing for every package sits on the Booster XT pricing page, and the Booster XT Official Website carries the short version of all of it.
