Load Boost Review: Semen Volume, Ingredients & Safety

Posted on October 9, 2026 by Mark Alexander

Editorial Verdict: 56/100

Load Boost is one of the more transparent semen-volume supplements we have reviewed, but its finished-product evidence does not match the confidence of its marketing. The current VB Health formula uses sunflower lecithin, pygeum, L-citrulline, bromelain, zinc, and copper, with a 4-capsule daily serving. Current label databases list 1,200 mg lecithin, 400 mg L-citrulline, 300 mg bromelain, 250 mg pygeum, 30 mg zinc, and 4 mg copper. That gives us far more to evaluate than a proprietary blend, but we found no peer-reviewed randomized trial of Load Boost itself showing a reliable increase in ejaculate volume, orgasm intensity, or semen taste.

Best for: someone specifically comparing semen-volume supplements and prioritizing a fully disclosed six-ingredient formula.
Skip if: you already take substantial zinc, use interacting medications, want product-level clinical proof, or expect a guaranteed increase in semen volume.
Verdict: transparent formula, reasonable guarantee, and some biologically plausible ingredients — but weak direct evidence for the product’s headline claims.

How We Scored Load Boost

Criterion	Score	Why it scored there
Formula Transparency	85/100	Current ingredient amounts are available from contemporary label databases, and the formula is not hidden behind a proprietary blend.
Finished-Product Evidence	35/100	We found ingredient research, but no peer-reviewed randomized trial of Load Boost itself.
Claim Realism	35/100	The official site makes direct claims about significantly increasing semen volume, intensifying orgasms, and improving taste without product-level clinical proof.
Safety Confidence	65/100	Most doses are within established safety limits, but 30 mg zinc is substantial and 4 mg copper is well above the RDA even though it remains below the adult UL.
Comparative Value	60/100	The 100-day guarantee and transparent formula are positives, but the price is premium relative to the limited direct evidence.

Overall score: 56/100. This is the arithmetic average of five equally weighted editorial criteria. It evaluates the formula, evidence, claims, safety, and value — not a hands-on product test.

What Is Load Boost?

Load Boost is a daily supplement from VB Health marketed for greater semen volume, stronger ejaculatory contractions, more intense orgasms, sperm and prostate support, and improved semen taste. The current official product page recommends four capsules once daily and says optimal results are typically achieved after about two weeks of consistent use.

The main editorial issue is that these are specific outcome claims. A plausible ingredient does not automatically validate a finished supplement, and we did not identify a peer-reviewed randomized controlled trial showing that Load Boost itself reliably increases ejaculate volume or orgasm intensity.

Current Formula and Doses

Ingredient	Current reported amount	Editorial assessment
Sunflower lecithin	1,200 mg	The largest ingredient in the formula. Lecithin is a phospholipid source, but strong clinical evidence that oral lecithin increases ejaculate volume in healthy men is lacking.
L-Citrulline	400 mg	Supports nitric-oxide biology, but the dose is below the 1,500 mg/day used in a human study that improved erection hardness in men with mild ED.
Bromelain	300 mg	A proteolytic enzyme with anti-inflammatory and digestive research; direct evidence for improving semen taste is lacking.
Pygeum	250 mg	Has human evidence related to prostate and urinary symptoms, but direct evidence for increasing semen volume is limited.
Zinc	30 mg	Relevant to male reproductive biology and semen quality, but already supplies 75% of the adult UL before food or other supplements are counted.
Copper	4 mg	Helps offset the copper-depleting effect of higher zinc intake, but 4 mg is still a high supplemental amount relative to daily requirements.

The current VB Health page specifically lists L-citrulline. Some older label records for Load Boost list L-arginine instead, which indicates the product has changed over time. For this review, we give more weight to the current official page and current supplement databases that list L-citrulline.

Does Load Boost Increase Semen Volume?

The strongest ingredient-level case is zinc. A systematic review and meta-analysis found lower seminal zinc in infertile men and reported improvements in semen volume, sperm motility, and normal morphology with zinc supplementation. That finding is relevant, but it does not establish that zinc increases semen volume in every healthy man or that Load Boost as a finished formula produces the same result.

Lecithin and pygeum are frequently used in the semen-volume supplement category, but we did not find high-quality human trials demonstrating that either one, at the Load Boost dose, reliably increases ejaculate volume in healthy men.

That means the product’s core claim remains biologically plausible but clinically unproven at the finished-product level.

What About Orgasm Intensity and Blood Flow?

L-citrulline is a nitric-oxide precursor and has legitimate human research for erectile function. In a small human study, 1.5 grams per day improved erection hardness in men with mild erectile dysfunction. Load Boost’s current reported dose is 400 mg — less than one-third of that amount.

That does not mean 400 mg is useless, but it makes it difficult to borrow the stronger results from higher-dose studies. We also found no clinical trial showing that 400 mg of L-citrulline increases ejaculatory force or orgasm intensity.

Does Bromelain Improve Semen Taste?

VB Health says bromelain helps balance bodily-fluid alkalinity and improve semen taste. We could not identify convincing peer-reviewed human trials demonstrating that bromelain supplementation measurably improves semen flavor. That claim should therefore be treated as marketing rather than established clinical evidence.

Safety and Dose Considerations

The biggest safety consideration is zinc. Load Boost provides 30 mg per serving. The NIH adult tolerable upper intake level is 40 mg per day from all sources. Thirty milligrams is below the UL, but it leaves relatively little room for zinc from food, multivitamins, or other supplements. Long-term excessive zinc intake can contribute to copper deficiency and other adverse effects.

Load Boost also includes 4 mg of copper. The NIH adult copper UL is 10 mg per day. Four milligrams is below that limit, but it is still a substantial supplemental amount.

L-citrulline can influence blood pressure, and bromelain may interact with certain medications or increase bleeding tendency in some circumstances. Anyone taking prescription medication or managing cardiovascular disease should review the formula with a clinician or pharmacist before use.

Price, Guarantee, and Value

When checked in October 2026, the official VB Health catalog listed Load Boost starting at $54.95. The product contains 120 capsules, with four capsules taken daily for a 30-day supply.

VB Health advertises a 100-day money-back guarantee on the first order of a supplement, with no need to return the product. That is a meaningful advantage over many competitors because it gives the user enough time to evaluate whether any change is actually noticeable.

The value question ultimately comes down to evidence. The formula is unusually transparent for this category, but the price is still high for a product without a finished-product clinical trial.

Pros and Cons

Pros

Transparent six-ingredient formula with disclosed current doses.
100-day first-order money-back guarantee.
Zinc has legitimate male-reproductive research.
Current formula uses L-citrulline rather than relying solely on herbal ingredients.
120 capsules provide a 30-day supply at the recommended serving.

Cons

No peer-reviewed randomized trial of the finished Load Boost formula identified.
Direct claims about significantly increasing semen volume and orgasm intensity exceed the product-level evidence.
400 mg L-citrulline is below doses used in positive erectile-function research.
30 mg zinc is substantial and can push total daily intake close to or above the adult UL when combined with other sources.
Evidence for bromelain improving semen taste is weak.
Premium monthly price relative to the level of direct evidence.

Final Verdict

Load Boost earns 56/100. It scores better than many semen-volume supplements because the current formula is transparent, the company offers a strong guarantee, and zinc has legitimate reproductive-health evidence. But the product’s specific claims — more semen, stronger orgasmic contractions, and improved taste — have not been validated in a peer-reviewed randomized trial of Load Boost itself. We view it as a plausible but unproven sexual-wellness supplement rather than a clinically established way to increase ejaculate volume.

Our Review Methodology

We use five equally weighted criteria: formula transparency, finished-product evidence, claim realism, safety confidence, and comparative value. Ingredient research does not count as proof that the finished branded formula works. We reviewed the current official VB Health product page, contemporary label databases, NIH safety guidance, and peer-reviewed research. We did not test Load Boost ourselves.
