Strong Cell Liquid NADH supplement
A single liquid supplement with NADH, CoQ10 and marine collagen, sold with a 90-day first-order guarantee and a monthly price near $170, held back by a thin evidence base for the finished product and limited label detail on the pages we could read.

A heavily marketed supplement with a real first-order guarantee, but little proof for the product itself and a price to weigh carefully
Strong Cell sells one product, a daily liquid made with NADH, CoQ10 and marine collagen, through its own store and a subscription. It publishes a refund policy, a cancellation policy, a phone line and a list of references, but we could not find a full ingredient dosage or any study of the finished product.
On policy, the main strength is a 90-day money-back guarantee on a first order with no return required, plus several ways to cancel a subscription. On evidence, the picture is thinner: the brand's reference list covers individual ingredients and includes general web articles, and the NADH trials we found were small studies in chronic fatigue syndrome with mixed results. Ratings are hard to read, since Trustpilot shows only two reviews and the larger rating we found is an aggregate with templated company replies. This is not medical advice; talk to a doctor or pharmacist before taking any supplement. We have not used the product.
Right for
- Shoppers who have read the label and want to try it once under the 90-day first-order guarantee
- People who will track the renewal date and know how to cancel
- Buyers who have already checked with a health professional
Wrong for
- Anyone expecting proof that this specific product works
- People who want a full ingredient dosage before buying and cannot find it
- Buyers who might not notice recurring charges, which the 90-day guarantee does not cover
+What it gets right
- First-order guarantee. A full refund within 90 days of delivery on a first order, with no return required, according to the refund policy.
- Several ways to cancel. Subscriptions can be changed online with a one-time code, by phone or by email, and a reminder email is sent 3 days before each order processes.
- Prepaid label for later returns. For 30-day returns of unopened product, Strong Cell provides a prepaid return label.
- Published contact details. A phone line (1-888-596-0155, weekdays 9am to 5pm CST), an email address and a company address in the terms are listed.
- Disclaimers are shown. The pages carry the FDA statement that the claims have not been evaluated and that results vary.
−Where it slips
- No studies of the finished product. The 10 references on the brand's page concern NADH, collagen or an NADH and CoQ10 combination, and several are general web articles.
- Dosage not found on the pages we read. We could not read a Supplement Facts panel with the amount of each ingredient, so we cannot compare doses with the trials.
- Inconsistent claims. The home page says “Over 2 Million Sold” while another page says “Over 1 Million Sold”, and we could not verify either.
- Guarantee has limits. Recurring subscription charges, free-trial conversions and duplicate accounts are excluded from the 90-day guarantee, and later orders get 30 days for unopened product only.
- Thin independent ratings. Trustpilot shows two reviews and says the company has not replied to negatives; the 4.5 aggregate we found has templated replies and a small visible sample.
- Fine print on disputes. The terms require binding arbitration in Collin County, Texas, and bar class actions, and the shipping policy page did not display in our check.
Weighted for evidence, guarantee terms, subscription clarity, transparency and reputation
Evidence for the product's claims and the clarity of the terms carry the most weight. This is a desk-research score: we have not used the product, and nothing here is medical advice.
The long version
What Strong Cell is, what it costs, what the evidence shows, how the guarantee and subscription work and what customers report.
What Strong Cell is
Strong Cell sells a single product, Strong Cell Liquid, offered as a 30 Day Box. The brand describes it as daily cellular nutrition built around NADH, marine collagen and CoQ10, with B vitamins, selenium and vitamin K as supporting ingredients, and it says the product is stimulant-free. It lists GMP certification, third-party testing and US manufacture as badges, which are the brand's own statements and which we could not verify. The home page also shows a “Clinicians' Choice” badge that says 728 clinicians share the product on FrontrowMD without compensation; we did not check this.
The terms of service name the operator as Strong Cell and list an address in Plano, Texas, and returns are sent to an address in Bartonville, Texas. Social handles on the site include “wellurastrongcell”, and some retail listings call it Wellura Strong Cell, but the pages we read do not explain the relationship, so we do not name a parent company.

Price and what you get
The product page shows Strong Cell Liquid, 30 Day Box, from $169.99 a month with a 15% Subscribe & Save banner and a price of $5.67 per serving, which matches $169.99 divided by 30. The page does not say whether $169.99 already includes the 15% discount, so check the final price at checkout. A retail listing describes the box as 30 individual 2 fl oz bottles taken once daily; we could not confirm the serving size on the brand's own pages.
The more important gap is the label. The pages we could read name the ingredients but give no amounts, and the FAQ answers did not display in our check. A press release quoted per-bottle amounts of 40 mg of NADH, 420 mg of CoQ10 and 1,560 mg of collagen, but we could not match that to a Supplement Facts panel, so read the label on the product page or the bottle before you rely on any figure.
The evidence
Strong Cell's claims go further than most. The home page says “Studies show up to 4x better fatigue improvement”, that its microencapsulation delivers near clinical grade NADH absorption, and that there are 10 human trials supporting the core ingredients. We looked for the support. The references page lists 10 references: nine on NADH and one on collagen. None of them tests the Strong Cell product, several are general web articles (including WebMD, VeryWell Health and ProHealth), two PDFs are hosted on a site that appears to belong to an NADH manufacturer, and one study title appears twice.

Outside the brand's page, the oral NADH research we found is small and mixed, and it concerns chronic fatigue syndrome, not general tiredness. A 1999 pilot trial of 26 patients using 10 mg of a stabilized NADH form found 8 of 26 responded favorably versus 2 of 26 on placebo, and its authors, some of whom are linked to the NADH maker, called for larger trials. A larger 2010 trial of 86 enrolled and 77 completing patients using 20 mg found no significant differences in most measures, with lower anxiety and maximum heart rate after a stress test as exceptions. RxList rates NADH for chronic fatigue syndrome as having insufficient evidence to rate and says there is not enough information to set a dose range. None of this tests Strong Cell's formula or delivery method.
Guarantee and returns
The refund policy has two tracks. On a first order, you can contact Strong Cell within 90 days of delivery for a full refund, and no return is required. On later orders, you must contact the company within 30 days of delivery and ship the return within the same 30 days; the product must be unopened, unused and in its original packaging, the return must be authorized in advance, and Strong Cell provides a prepaid label. Refunds go to the original payment method, but no processing time is stated.

Read the exclusions: initial purchases from a free trial that convert to a paid subscription are excluded from the 90-day guarantee except where the law requires a refund, recurring subscription charges are not eligible, a second account with a different email, address or phone does not count as a new customer, and Tru Med orders are non-refundable. Damaged or defective products are replaced.
Subscription and cancelling
Orders ship automatically every 30, 60 or 90 days, at the frequency chosen at checkout. The cancellation page says a reminder email is sent 3 days before each order processes, and you can manage or cancel online with a one-time code, by phone at 1-888-596-0155 or by email at [email protected]. If you cancel before processing you are not charged for that cycle. If an order has processed but not shipped, you should contact the company immediately; once it has been processed and fulfilled the page says it cannot be stopped, although unopened items can be returned within 30 days.

The page does not state the auto-ship price or any pause or skip option. The terms of service add that the company may charge your payment method on a recurring basis without asking each time, that disputes go to binding arbitration in Collin County, Texas under American Arbitration Association rules, and that class actions are barred.
What customers report
Trustpilot showed a claimed profile (since January 2023) with 3.6 out of 5 from 2 reviews on 30 Oct 2026: one four-star review from a customer whose problem was resolved and one one-star review whose text we could not read. Trustpilot says the company has not replied to negative reviews. Two reviews are too few to say anything about typical experience.
A Birdeye page for Wellura Strong Cell shows 4.5 stars from 382 reviews (355 Google, 26 Facebook and 1 Birdeye), but only 8 Facebook reviews were visible to us. They describe more energy, focus and better-looking skin after six weeks to three months, and one reviewer said the price is a strain. Nearly every company reply uses the same phrasing and some reviews read like advertising, so treat this as personal testimony, not verified results. The brand also claims “4.8 from 10,000+ customers” on its home page, which we could not trace to a source.
Buying advice
Talk to a doctor or pharmacist before taking any supplement, particularly if you take medication, are pregnant or breastfeeding, or have a health condition. RxList notes that not enough is known about NADH in pregnancy and breastfeeding, and the FDA does not review dietary supplements for safety before they are sold. Read the Supplement Facts panel for the amount of each ingredient, compare it with the doses in the studies you rely on, and treat testimonials and badges as marketing.
If you decide to try it, use the first-order guarantee knowing it covers only the first order, screenshot the checkout page and price, set a reminder before the second shipment and know the cancellation route in advance. For a checklist, read our guide on how to evaluate a supplement before you buy, and for another supplement brand see our Clean Nutra review.

The guarantee is simplest for a single first order. If you plan to subscribe, assume later shipments fall under the stricter 30-day terms and read the supplement buying checklist before you pay.

A strong marketing story with limited proof, and a guarantee that is best used once
Strong Cell has clear first-order guarantee terms and several ways to cancel, which makes a single trial purchase lower risk than many subscription offers.
Weigh the thin evidence for this specific product, the missing dosage details on the pages we read, the exclusions that apply to renewals and the roughly $170 monthly price. Talk to a health professional before taking it.

How this review was put together
This is a desk-research review. We have not used Strong Cell, and nothing here is medical advice. Product, price and policy details come from strongcell.com (checked 30 Oct 2026), evidence from the brand's references page, two PubMed abstracts and RxList, and reputation from Trustpilot and Birdeye. We could not read the shipping policy, the FAQ answers or a Supplement Facts panel on the pages we fetched, and we say so where it matters. We wrote our own text. The images are our own screenshots of public Strong Cell pages, taken on 30 Oct 2026 and shown for review and commentary; the content and branding belong to Strong Cell, and we will remove them if asked. We did not download or reuse image files or logos, and we did not review the brand's affiliate programme terms.
