All three are a single payment. Confirm the current amount at checkout before you pay.

Order through the checkout linked from this page and the 30-day cover is attached to your order automatically. Keep the confirmation email, because it carries your order number, and keep any bottles you have not started in their sealed original packaging. Those two things are all you need if you later decide to send a pack back. Bottles bought from a marketplace reseller are not covered.

No. The three packs are one-off payments with no auto-ship and nothing to cancel later. The store does run a separate optional subscription programme, so simply check the order summary shows the one-off pack you picked before you pay. If you ever did join a subscription, it can be cancelled from your account or through support, at least 48 hours before the next billing date.

You have 30 days from the day your order arrives. Post the unopened bottles back with a courier of your choice, then fill in the return form in the Help Centre with the tracking number and your order number. Returns are inspected within about seven to fourteen working days and the refund goes to your original payment method within five to twenty working days after that. Return postage is yours to arrange, and the cover applies to bottles still sealed in their original packaging.

Orders are processed within one to three working days and delivery usually takes two to fourteen working days, with a tracking link emailed to you when your pack ships. Delivery is free on the two and three-bottle packs and £4.95 on the single bottle. Payment goes through card, Klarna, PayPal or Apple Pay, and the checkout is operated by Haur B.V., a registered Dutch company, with Haruki Limited as seller of record.

No. It is not stocked by Amazon, eBay, Holland & Barrett, Boots or any high-street chemist. Anything listed on a marketplace comes from a third-party reseller, where you cannot verify the batch, storage or expiry date, and the 30-day money-back cover does not apply to it. Ordering through the checkout on this page is what keeps the guarantee on your order, and the three-bottle pack at £36.65 a bottle is the cheapest price there is anyway.

Plan on several weeks rather than days. Buyer feedback describes steadier daytime energy and less snacking between meals building up over the first month, which matches how the research on this kind of botanical blend reads. Take one capsule each morning with water, every day, and judge it at the one-month mark. Anything promised in days is marketing rather than physiology. Individual results vary.

Chromium at 100 micrograms and zinc at 5.5 milligrams, both with authorised EU health claims, plus a botanical blend of about 510 milligrams led by berberine, banaba leaf and alpha-lipoic acid, with green tea, milk thistle, resveratrol, cayenne and Korean ginseng. One capsule a morning, 30 to a bottle. If you take daily medication for blood sugar or cholesterol, or anything processed by the liver, show the ingredient list to your pharmacist first. It is not suitable under 18, or if you are pregnant or breastfeeding.

Each bottle holds 30 capsules, a one-month supply at one capsule each morning with water. Two minerals are printed with their amounts, and eight plant ingredients sit inside a botanical blend stated at about 510 milligrams.¹

Read as a whole, it is a mineral base with an authorised-claim footing, a botanical lead in berberine, and a supporting layer aimed at daily energy and the antioxidant side. Vegan capsule, made in the EU to a stated GMP standard.¹

The strongest footing in this formula belongs to the two minerals, because their claims have been through a regulatory review rather than a marketing department. Chromium at 100 micrograms sits above the 40 microgram threshold at which the EU register grants the claim that it contributes to the maintenance of normal blood glucose levels and to normal macronutrient metabolism.³ Zinc at 5.5 milligrams likewise carries the authorised claim for normal carbohydrate metabolism and normal metabolism of fatty acids.⁴ That is a stronger basis than most blends in this category can point to.

Berberine, the botanical lead

Berberine is the plant compound with the deepest research behind it here. A dose-response meta-analysis of randomised controlled trials, published in Complementary Therapies in Medicine in 2020, found berberine supplementation produced statistically significant improvements in body mass index and waist circumference against placebo.⁵ The trials in that analysis generally used around 1000 to 1500 milligrams a day on its own, which is more than a 510 milligram blend delivers, so the sensible way to read the berberine in Corevalin is as daily botanical support sitting on top of the two authorised-claim minerals, rather than as a standalone clinical dose.

The supporting layer

Banaba leaf supplies corosolic acid, linked in small human trials to a lower rise in glucose after a meal.⁶ Alpha-lipoic acid has meta-analysis support for glycemic markers. Green tea catechins with a little caffeine raise 24-hour energy expenditure by a measurable amount in controlled trials, and Korean ginseng has randomised-trial support for reducing fatigue. Together they back the daily-energy side of the label.

One capsule each morning with a glass of water, 30 to a bottle. Because green tea brings a little caffeine with it, the morning is the right slot rather than the evening.
