Quietum Plus Review 2026Pros, Cons and Real Feedback

What is in it, per 2 capsules: zinc 26 mg, vitamin B12 54 mcg, vitamin B6 3.8 mg, other B vitamins, L-arginine 100 mg, L-tyrosine 100 mg, BioPerine 500 mcg and an 802 mg blend of 12 herbs with no amounts given, including epimedium, tribulus, maca, ashwagandha, dong quai, muira puama and mucuna.

What the evidence says:

• The American Academy of Otolaryngology, Head and Neck Surgery recommends against dietary supplements, including zinc, for persistent, bothersome tinnitus.
• A Cochrane review found no evidence that zinc helps tinnitus.
• We found no tinnitus trial for any of the 12 herbs.
• Zinc at 26 mg is above the NHS 25 mg limit.

The BBB rates Quietum Plus D, with 37 complaints closed in 3 years. The refund lasts 60 days, but every bottle must be posted back at your cost.

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

• Zinc: 26 mg. Cochrane: "no evidence" for tinnitus. Above the NHS 25 mg a day limit; the label also says not to exceed 4 capsules a day (52 mg).
• Vitamin B12: 54 mcg vs 2,500 mcg weekly injections in a small pilot. No difference from placebo in the larger trial.
• The 12-herb blend: 802 mg in total, about 67 mg per herb if split evenly. The real split is not disclosed, and no herb has a tinnitus trial that we could find.
• Standard care, for contrast: hearing tests, hearing aids if there is hearing loss, and cognitive behavioural therapy.

The label says 2 capsules a day for at least 8 weeks. A 60-capsule bottle lasts a month.

Our Transparency Score checks five things a buyer can verify. Quietum Plus scores 1 out of 5.

• Label with doses: no. The vitamins, zinc, arginine and tyrosine are dosed, but the 12 herbs share an 802 mg blend with no split.
• Identifiable company: no. The label says "Distributed by: Quietum Plus" at 19655 E 35th Dr. #100, Aurora, Colorado, the same suite address used by other products we have reviewed. No legal entity or manufacturer is named.
• Refund terms in writing: yes. 60 days from delivery, with conditions.
• Independent testing shown: no. The page claims an "FDA-approved facility"; the FDA does not approve dietary supplements.
• Study on the finished product: no. The "several dozen studies" are animal, cell and computational work.

The BBB rates Quietum Plus D, not accredited, with 37 complaints closed in the last 3 years and 34 customer reviews. The page cites "11,388 reviews" and says "97% of customers order 6 bottles"; neither can be checked.

Correction. An earlier version of this review listed vitamin B12, zinc, magnesium glycinate, ashwagandha, ginkgo, bacopa, taurine and St. John's wort with no amounts, said it was made in the United States, showed no price and no refund terms, and gave a $1.33 a day cost. The label has B12, zinc and ashwagandha, plus nine other herbs and amino acids, states no country of manufacture, and costs $1.63 to $2.63 a day. We have corrected it.

Prices when we checked in September 2026:

• 2 bottles: $158, plus $9.99 shipping.
• 2+1 bottles: $207, free US shipping.
• 3+3 bottles: $294 ($49 each), free US shipping.

That is about $2.63 a day for 2 bottles, $2.30 for 3 and $1.63 for 6 (our calculation). Canada, the UK, Ireland, Australia and New Zealand pay $15.95 shipping. The page shows "retail" prices of $358, $537 and $1,074 beside these, so every price appears as a discount.

Refunds. The refund page says "you have 60 days from the moment you get your package". You must "Send all the bottles back to us (no matter if they are empty or not)" to 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 bottles and the Packing Slip" (5 to 10 days).

• Zinc: 26 mg a day. The NHS says "Do not take more than 25mg of zinc supplements a day unless advised to by a doctor"; more zinc reduces copper absorption, which can lead to anaemia.
• Mucuna: a lab study of six commercial products found levodopa content from 6% to 141% of label claims, up to 720 mg a day. Quietum Plus does not state its extract's levodopa.
• Dong quai: a case report describes a more than 2-fold rise in INR in a patient on warfarin after 4 weeks.
• Ashwagandha: case reports link it to jaundice and liver injury.

The label says to consult a physician if you have a medical condition, yet the sales page says it was "designed for all ages and medical conditions". There is no clinical study on Quietum Plus itself.
