Editor's Verdict
👍 Pros
- ✓The two formulation choices that matter are both the better ones: lichen-derived D3 is the only genuinely vegan form of cholecalciferol, and all-trans MK-7 is the long-acting bioactive isomer, with cis-MK-7 being inactive, so naming it signals a serious formulator
- ✓A 60-day money-back guarantee requiring no return at all is among the most generous terms in supplements and makes a first order essentially risk-free on paper
- ✓Genuine independent corroboration at 4.6 from 1,236 Trustpilot reviews, with recent activity and a very low 4% one-star share
- ✓Replying to every negative review within 48 hours is real accountability, and many reviewers describe service as prompt and friendly
- ✓Named founders with a stated six-year development history and a medically qualified co-founder as Chief Medical Officer, rather than an anonymous brand
- ✓The D3 claims use the authorised European wording about normal muscle function, cell division, teeth and immune function, which is correct regulatory practice rather than overreach
- ✓An oral spray is a practical format for anyone who dislikes capsules, and vitamin D absorbs well this way
- ✓Subscriptions can be paused or cancelled at any time, and free shipping is offered across three markets
👎 Cons
- ✕The vitamin K2 amount is never stated anywhere on the page, which is the single most important number on a D3 and K2 product, since MK-7 trials use roughly 90 to 180 micrograms daily and without the figure the formula cannot be assessed
- ✕At 3,000 IU per spray the vitamin D dose is well above the UK recommendation of 400 IU and the usual adult RDA, which is fine for many people but leaves little headroom if you also take a multivitamin or another D supplement, given the 4,000 IU adult upper limit
- ✕The price is inconsistent, shown as £49.99 in the page metadata against From £29.99 on the homepage card, with no prices displayed at all for the three-bottle, six-bottle or subscription options
- ✕No third-party laboratory testing is mentioned anywhere; stringent and rigorous quality standards are claimed without naming a laboratory, certification or testing panel
- ✕The recurring complaint in independent reviews is unanswered email about billing, refunds, subscriptions and account access over long periods, which directly threatens the practical value of an email-only refund guarantee
- ✕There is no phone number published at all, which matters precisely because the guarantee and subscription management both run through email
- ✕Customer numbers contradict each other tenfold, given as 54,000-plus on the product page and 4,600-plus on the homepage
- ✕The Covent Garden address is one of the most commonly used registered office addresses in the UK rather than an operating premises, so it tells you little about the business
- ✕A copy error on the product page describes the peppermint oil ingredient as cinnamon extract, which is a quality control lapse on an ingredient list
- ✕The brand's 185x more bioavailable claim on its curcumin product cites no study or data
- ✕Independent reviewers also report lost or delayed deliveries, one case of difficulty cancelling a subscription, and some unexpected side effects from the liquid formula

Frequently Asked Questions
<p>KURK advertises free shipping, and the company states it serves customers in the UK, Australia and the US, with products made in the UK. No threshold or delivery timeframe is published on the pages reviewed, so check what appears in your cart before applying a coupon, and note that independent reviewers report occasional lost or delayed deliveries. If you are ordering from Australia or the US, allow for international transit and confirm whether any customs charges apply at your end. Pricing is inconsistent across the site, appearing as £49.99 in the product page metadata and From £29.99 on the homepage card, with no figures shown at all for the three-bottle, six-bottle or subscription options, so verify the actual charge at the payment step rather than relying on the listing. There is no phone number, so keep your order confirmation and raise any delivery issue by email to talk@kurk.life with your order number.</p>
<p>KURK offers a 60-day money-back guarantee that requires no return at all: email talk@kurk.life within 60 days of purchase and request a full refund. On paper that is among the most generous terms in supplements, since you keep the product and send nothing back, and subscriptions can be paused or cancelled at any time. The practical caveat is important. The recurring complaint in independent reviews is that emails about billing, refunds, subscription changes and account access went unanswered for extended periods, and with no phone number published, email is the only route to exercise the guarantee. If you need a refund, send it clearly headed with your order number, keep a copy, follow up in writing if you do not hear back within a few days, and note that the company does reply to every negative public review within 48 hours, which can be an effective escalation route. The detailed policy page could not be retrieved during this review, so confirm the refund processing timeframe in writing. Buying one-time rather than on subscription avoids the billing issues reviewers most often describe.</p>
<p>Every Kurklife coupon listed on smartstorereview is checked before publication and carries a date so you can see how recent it is. Enter the code in the discount field at checkout and confirm the order total actually drops before you pay, since that confirmation on the payment page is the only reliable proof a code has worked. Codes generally cannot be stacked, so if you hold more than one, test each separately and keep whichever saves more. Note the store runs its own promotions, including 20% off the Wellness Starter Pack with free gifts, subscription savings and bundles from £59 to £229, and percentage codes commonly exclude subscriptions and already-discounted bundles, so compare final totals rather than headline percentages. Given that site pricing itself is inconsistent, with £49.99 and From £29.99 both appearing for this product, check the charge in your cart carefully rather than assuming the lower figure. If a code requires a subscription, weigh that against the billing and cancellation difficulties some independent reviewers describe.</p>
<p>The store runs a standard hosted checkout and accepts major credit and debit cards including Visa, Mastercard and American Express, along with common digital wallets such as Apple Pay, Google Pay, Shop Pay and PayPal where available in your region. Buy-now-pay-later options such as Klarna may appear on larger bundle orders depending on cart value and location. Subscriptions set up a recurring charge that the brand states can be paused or cancelled at any time, though some independent reviewers report difficulty doing so, so locate that control in your account immediately after ordering rather than waiting for a renewal. Payment is processed over an encrypted connection and card details are handled by the payment provider rather than stored by the store. Because the refund guarantee and subscription management both run through email only, with no phone number published, paying by credit card or PayPal is worth preferring over a debit card, since both give you an independent route to stop or dispute a recurring charge.</p>
<p>Two things are worth understanding before you start. On the vitamin D, 3,000 IU per spray is a meaningful dose, well above the UK recommendation of 400 IU a day and above the typical adult reference intake, though still below the adult upper limit of 4,000 IU. That means it is a reasonable dose for someone genuinely low in vitamin D, which is common in northern latitudes over winter, but it leaves little headroom if you also take a multivitamin, a cod liver oil or another D supplement, so add up your total. The sensible approach is to ask your GP for a 25-hydroxyvitamin D blood test rather than guessing, particularly before taking this amount long-term. Excess vitamin D over months causes hypercalcaemia, with nausea, excessive thirst, kidney stones, kidney damage, confusion and heart rhythm disturbance; it is uncommon but real. Avoid vitamin D supplementation without specialist advice if you have sarcoidosis or another granulomatous condition, hyperparathyroidism, existing high blood calcium, or kidney disease, and discuss it with your doctor if you take a thiazide diuretic or digoxin, both of which interact with calcium levels. Vitamin D is recommended in pregnancy in the UK, but at 400 IU rather than 3,000, so discuss the dose with your midwife. On the vitamin K2, this is the critical point: vitamin K directly opposes the action of warfarin and related vitamin K antagonists such as acenocoumarol and phenindione, so if you take one of those, do not start a K2 supplement without involving your anticoagulant clinic, because it will alter your INR and can raise your risk of a clot. Direct oral anticoagulants such as apixaban and rivaroxaban are not affected in the same way, but still worth mentioning to your pharmacist. Otherwise K2 as MK-7 is well tolerated with no established upper limit, and the all-trans form specified here is the biologically active one. Note that the actual amount of K2 is not published on the page, so email and ask for it, since MK-7 research generally uses 90 to 180 micrograms daily and a lower amount may do little. Finally, the spray contains peppermint oil, which can aggravate reflux or heartburn in susceptible people, and should not be given to infants.</p>

I had been looking for a vegan D3 that was not from lanolin and this is one of very few that uses lichen, which is why I bought it. Specifying all-trans MK-7 rather than just saying K2 told me they knew what they were doing, since my pharmacist confirmed the cis form does nothing. One minty spray a day is far easier than remembering a capsule.
Alasdair R. Verified Buyer
★★★★☆
Good product and the 60-day refund with nothing to send back is as fair as it gets. Four stars because the K2 amount is not printed anywhere, so I had no way to compare it against the 100 microgram products I had been looking at, and the price showed as £49.99 in one place and from £29.99 in another. Support did reply, just not quickly.

The spray itself was fine but sorting out my subscription was not. Three emails about a billing question went unanswered over a fortnight and there is no telephone number anywhere, which is a problem when the only way to claim the guarantee is email. I also noticed the ingredient list describes the peppermint oil as cinnamon extract, which did not fill me with confidence.
