Ultra Boost Juice Review 2026Does It Actually Work?

What is in it, per 4.4 g scoop: a 2.6 g blend of vegetables, fruit and mushrooms, a 1.2 g blend of 11 herbs (including ashwagandha and Korean ginseng), a 406 mg fibre and enzyme blend, and 2.5 billion probiotic CFU.

What it claims: the sales page says it makes "Any Penis Increase By 35%", adds "at least 3 inches" in 30 days, and helped people "recover from their type II diabetes".

What the evidence says:

• We found no trial showing an oral supplement makes a penis larger. The European Association of Urology guideline lists none.
• Its "penis carrot", "penis banana", "penis asparagus" and "penis beet" are carrot, banana, asparagus and beet on the label.

The refund lasts 60 days, but every bottle must be posted back at your own cost.

Our Dose Check compares the label with the best human studies.

• Whole herb blend: 1.2 g for 11 herbs, about 109 mg each if split evenly. The real split is not disclosed.
• Korean ginseng: undisclosed vs 2,700 mg a day for 8 weeks. Under 44%, even if the whole blend were ginseng. Cochrane still calls that effect trivial.
• Ashwagandha: undisclosed. No penis-size or erection trial found.
• Green tea: undisclosed.
• Zinc: 8.2 mg, within the NHS 25 mg limit.
• "3 inches in 30 days": no oral-supplement trial found; the European urology guideline lists none.

The label says 1 scoop, once or twice a day, in water. A 30-scoop bottle lasts 15 to 30 days.

Our Transparency Score checks five things a buyer can verify. Ultra Boost Juice scores 1 out of 5.

• Label with doses: no. Three blends are given as totals only; eleven herbs share 1.2 g.
• Identifiable company: no. The label says "Distributed by: Ultra Boost Juice" in Englewood, Colorado. Refunds go to 19655 E 35th Dr #100, Aurora, the same suite address used by other products we have reviewed. No legal entity is named, and the BBB has no profile.
• Refund terms in writing: yes. 60 days from shipment, all bottles returned.
• Independent testing shown: no. The contact page says "FDA accredited"; the FDA does not approve supplements.
• Study on the finished product: no. The references page lists news stories, a survey of women's penis-size preferences and a ginkgo case series.

The page claims "zero side effects", ingredients "BELOW the allergy-triggering levels" and proof by "more than 64,000 people". None is backed by data on the page.

Correction. An earlier version of this review described a "liquid" sexual-performance formula built on maca, tribulus, epimedium, ginseng and L-arginine with no published amounts, said it was made in the United Kingdom, showed no price and no refund terms, and gave a $1.70 a day cost. It is a powder with a greens-and-herbs label, no country of manufacture is stated, and it costs $1.63 to $2.30 a day. We have corrected it.

Prices when we checked in September 2026:

• 1 bottle (30 scoops): $69, shown against a crossed-out $99.
• 3 bottles: $177 ($59 each).
• 6 bottles: $294 ($49 each).

US shipping is free; Canada, the UK, Ireland, Australia and New Zealand pay $15.95. At one scoop a day that is about $2.30 a day for one bottle and $1.63 a day for six, and double that at two scoops (our calculation).

Refunds. The refund page says "You have 60 days after we ship you your order". To get a refund, "you must send the supplement bottles back to us" at an address in Aurora, Colorado, "we do not support the return shipping costs", and the refund is processed "as long as you sent back ALL the supplement bottles".

• Liver: published case reports link ashwagandha products to jaundice and liver injury, which cleared in 1 to 5 months in four of five patients. The amount in this blend is undisclosed.
• Green tea extract: the USP review links hepatotoxicity to EGCG intakes from 140 mg a day and advises against taking it on an empty stomach. The amount here is undisclosed.
• Coconut: the label says it contains tree nuts (coconut).
• Contamination risk: the FDA says sexual-enhancement products "are likely to be contaminated with dangerous hidden ingredients". We found no test of this product.

The label says to consult a physician if you take medication. The page's "zero side effects" claim has no study behind it, and there is no clinical study on Ultra Boost Juice itself.
