What is inside Vigor Boost
If you only read one thing
Every Vigor Boost gummy carries an 82 mg blend of five actives: L-citrulline, tongkat ali root, saw palmetto extract, curcumin and L-theanine. The blend is dosed as a whole rather than ingredient by ingredient, so the panel below shows the total, exactly as it is printed on the bottle. Two of the five have a genuinely large evidence base behind them, two have a long traditional record and modest modern data, and one is there to smooth the edges.

We publish the blend total, 82 mg, because that is what the label states. We do not publish invented per-ingredient milligrams. If a store quotes you exact doses for each of the five, ask where the number came from.
Pillar one: blood flow
The circulation side of Vigor Boost rests on L-citrulline. Citrulline is a non-essential amino acid that the kidneys convert into arginine, and arginine is the substrate the body uses to build nitric oxide. Nitric oxide is the signal that tells the smooth muscle in a vessel wall to relax, which widens the vessel and lets more blood through at lower pressure. This is not a fringe idea. It is the single best studied mechanism in the whole sports and men's supplement category [5].
The reason formulators reach for citrulline rather than arginine itself is absorption. A large share of oral arginine is broken down in the gut and liver before it reaches circulation. Citrulline skips that first pass and raises blood arginine more efficiently, gram for gram [3]. That is why citrulline shows up in pre-workout products, in cardiovascular formulas and in men's vitality blends like this one.
Curcumin sits in the same pillar for a different reason. Curcumin is the yellow pigment fraction of turmeric root, and the modern interest in it has always been about inflammatory signalling rather than about flow directly [1]. Vessels dealing with less background inflammation respond better to the signals they are given. The honest caveat, and the one the NCCIH itself makes, is that curcumin is poorly absorbed on its own and that human results have been mixed [1].
What this pillar is not
Nitric oxide support is not a drug mechanism and Vigor Boost is not a treatment for erectile dysfunction or for high blood pressure. If either of those is what you are dealing with, the right first step is your doctor, not a gummy.
Pillar two: hormonal balance and male tissue
Tongkat ali root, Eurycoma longifolia, is the traditional Southeast Asian botanical that carries most of the hormonal weight in Vigor Boost. It has been used for generations in Malaysia and Indonesia in men's tonics, and the modern literature on it looks at male hormone profiles, stress hormones and perceived vitality [6]. It is a real research subject with real limitations: trials are small, extracts differ enormously between suppliers, and results are far from unanimous.
Saw palmetto extract is the other half of this pillar and one of the most widely taken men's botanicals in the United States. Its long association is with prostate comfort and urinary flow in older men. The NCCIH summary is worth reading in full, because it is candid: some studies show benefit, and the largest, best controlled ones have generally not [2]. We include it because it belongs in a men's daily formula by convention and by customer expectation, and we would rather tell you where the evidence sits than imply more than exists.
Between them, these two are why Vigor Boost is formulated as a men's product rather than a general circulation supplement. Neither of them is a hormone. Neither is a steroid or a prohormone. They are plant extracts taken daily.
Pillar three: the calm side
L-theanine is the fifth active and the one people usually skip past. It is an amino acid found almost exclusively in tea leaves, and it is studied for the specific state it produces: relaxed but alert, without sedation [4]. In a men's vitality blend it does two jobs. It softens the restless edge that stimulating botanicals can leave, and it supports the part of the picture men rarely name out loud, which is that stress and poor sleep flatten drive faster than almost anything else.
Vigor Boost contains no caffeine. That is deliberate. Adding caffeine would produce a felt effect on day one and would make the product easier to sell. It would also make it something you cannot take at 8pm and cannot take alongside your existing coffee habit without doing arithmetic.
Why the doses are shown as a blend
Vigor Boost declares an 82 mg proprietary blend rather than five separate numbers. We would rather be straight about what that means for you. A blend declaration is legal and extremely common in this category, and it protects a formula from being copied line for line. It also means you cannot compare our citrulline milligrams against another product's citrulline milligrams, because ours are not published.
What you can do is compare what is disclosed: the five actives are named, in descending order of weight as the regulations require, and the total is printed. Judge the product on the 60-day window rather than on a spreadsheet. That is exactly what the guarantee is for.
What Vigor Boost does not claim
Vigor Boost is a dietary supplement. It is not a medicine. It does not treat erectile dysfunction, low testosterone, benign prostatic hyperplasia or any other diagnosed condition, and nothing on this site should be read as saying otherwise. The FDA does not approve dietary supplements before they are sold, and it has not evaluated any statement on this page [8].
Small glossary
- Nitric oxide
- A short-lived gas the body makes from arginine that tells blood vessels to relax and widen.
- Proprietary blend
- A group of ingredients declared with one combined weight rather than individual weights.
- Bioavailability
- How much of a swallowed ingredient actually reaches the bloodstream in a usable form.
- cGMP
- Current Good Manufacturing Practice, the FDA framework covering how supplements are made, tested and documented.
- Adaptogen
- An informal label for plants used traditionally to help the body cope with physical or mental load. It is not a regulatory term.
- Daily Value
- The reference intake used on nutrition labels. Many botanical ingredients have none, which is why they show a dagger.
- Standardised extract

Label questions
What are the ingredients in Vigor Boost?
Vigor Boost contains an 82 mg blend of L-citrulline, tongkat ali root, saw palmetto extract, curcumin and L-theanine per gummy, in that order of weight, plus the gummy base and flavouring printed on the bottle.
Is Vigor Boost safe?
For most healthy adult men, yes, at one gummy a day. The actives are food-derived amino acids and long-used botanicals rather than pharmaceutical compounds. Speak to your doctor first if you take blood pressure medication, nitrates, blood thinners, hormone therapy or erectile dysfunction medication, or if you have a prostate condition under treatment.
Does Vigor Boost have side effects?
The complaints we see are mild and uncommon: a little stomach unsettlement when taken on an empty stomach, and occasionally a headache in the first few days. Taking the gummy with food handles most of it. Stop and speak to a clinician if anything persists.
Is Vigor Boost FDA approved?
No, and neither is any other dietary supplement. The FDA does not approve supplements before sale [8]. What we can tell you is that Vigor Boost is produced in a facility registered with the FDA and operating to cGMP standards, and that these statements have not been evaluated by the FDA.
