Pb Sin 18, the once-daily capsule with chromium, zinc and guarana

Pb Sin 18 is a once-daily capsule: 40 mcg chromium, 15 mg zinc and a fixed-dose botanical and amino-acid matrix of guarana, apple cider vinegar, Jerusalem artichoke inulin, L-leucine and L-glutamine, 400 mg per capsule. Pb Sin 18 goes with lunch or dinner and two large glasses of water, formulated for UK adults who anchor their routine to one set meal. One capsule, one meal, done. Chromium and zinc form the authorised foundation, listed word for word in the GB NHC Register: 100% and 150% NRV in every capsule. We sell only through this official shop: sealed packs from our own stock, batch number on the box, 60-Day Money-Back Guarantee.

Full declaration

What's inside each capsule, milligram by milligram

Every Pb Sin 18 capsule contains seven ingredients, each with its milligram figure on the label. Chromium (as chromium picolinate) and zinc (as zinc citrate) come from the permitted list under Regulation (EC) No 1170/2009 and carry the authorised claims. The other five are fixed doses, from 100 mg guarana extract down to 50 mg L-glutamine. No proprietary blend, no lump sum: every amount listed on its own. The HPMC shell feels smooth and opens with a gentle twist; the powder inside is light brown and smells faintly of apple cider vinegar.

Pb Sin 18 carton flat lay with guarana seeds, apples, apple cider vinegar and Jerusalem artichoke tubers — The natural raw materials behind Pb Sin 18, alongside chromium and zinc in every daily capsule.

Chromium (40 mcg, 100% NRV): as chromium picolinate; carries two authorised claims.
Zinc (15 mg, 150% NRV): as zinc citrate; carries the third claim.
Guarana extract (100 mg): seeds of the Amazon vine Paullinia cupana, grown by the Sateré-Mawé of Maués; the formula's natural caffeine source.
Apple cider vinegar extract (100 mg): two fermentations (yeast, then acetic acid bacteria) in a capsule that needs no measuring.
Inulin from Jerusalem artichoke (100 mg): a fructan from the tuber of the North American sunflower Helianthus tuberosus, as a powder.
L-Leucine (50 mg): one of the nine amino acids the body cannot make itself; branched-chain, purely declared.
L-Glutamine (50 mg): the most abundant free amino acid in the body; rounds off the 400 mg matrix.

Apple cider vinegar capsules compared: capsule, liquid, gummy

Apple cider vinegar comes as a bottle, a gummy or a capsule. The difference is in the handling: measuring, taste, portability, swallowing. The capsule keeps the extract at 100 mg.

How to take Pb Sin 18 with lunch or dinner

Take one Pb Sin 18 capsule a day, whole and unchewed, with two large glasses of water, 15–30 minutes before or with lunch or dinner. If you're sensitive to caffeine, make it lunch: every capsule contains natural caffeine from 100 mg of guarana extract. No measuring spoon, no sharp vinegar taste: one capsule with your meal. If swallowing is difficult, open the HPMC capsule, stir the powder into water and drink it straight away. The powder disperses after about ten seconds and leaves a fine sediment. Time needed per day: under a minute.

Authorised wording · GB NHC Register

What chromium and zinc contribute

Pb Sin 18 is a food supplement; its authorised health claims come from two minerals, quoted word for word from the GB NHC Register (the retained list under Regulation (EU) No 432/2012). Each capsule provides 40 mcg chromium (100% NRV) and 15 mg zinc (150% NRV): high in zinc and chromium. For these two minerals, the following health claims are authorised:

Chromium contributes to the maintenance of normal blood glucose levels
Chromium contributes to normal macronutrient metabolism
Zinc contributes to normal carbohydrate metabolism

Guarana, apple cider vinegar, inulin, L-leucine and L-glutamine complete the formula as a fixed-dose botanical and amino-acid matrix: 400 mg per capsule, every milligram on the label. In Great Britain and the EU, health claims are reserved for vitamins and minerals. So the claims block names chromium and zinc in the authorised wording, and the other five are in the declaration with origin and amount: transparency to the highest European declaration standard. Origin, alkaloids and safety data for each ingredient: the research behind each ingredient.

Good to know before you start

Every capsule brings natural caffeine from 100 mg of guarana extract: count it with your tea and coffee, and choose lunch if you're sensitive. Formulated for adults; not recommended for children or during pregnancy and breastfeeding. Prescription medicines for your metabolism, levothyroxine (morning, empty stomach; the capsule at lunch or dinner), tetracycline or quinolone antibiotics: ask your GP or pharmacist about the gap. 15 mg zinc per capsule stays below the UK safe upper level of 25 mg a day, multivitamin zinc included. Per the label, the formula affects neither the contraceptive pill nor high blood pressure. Rarely (around 1 in 1,000), a mild dry mouth can occur. Existing conditions: ask your doctor first.

Straight answers before you order

Can I buy Pb Sin 18 at Boots, Holland & Barrett or a pharmacy?

No. We sell Pb Sin 18 only through this official UK shop, not on the high street, in pharmacies or on marketplaces. That way every pack comes sealed from our own stock, with the batch number and best-before date on the box (check them with the batch checker above the price table), at official prices from £1.22 per day, with free delivery from two packs and a 60-Day Money-Back Guarantee on every order placed here.

Pb Sin 18 reviews: what is everyday use actually like?

Straightforward, because the routine hangs on one set meal: one capsule, two large glasses of water, lunch or dinner. The HPMC capsule is smooth and tasteless going down; if you'd rather drink it, open it and stir the powder into water. For days out, a pill box with a week's capsules is enough. The routine log above covers the first 30 days. If you'd rather try the routine first, you can, without risk: 60-Day Money-Back Guarantee.

Does Pb Sin 18 have any side effects?

Rarely (around 1 in 1,000), the label notes a mild dry mouth; the two glasses of water are part of the routine. Per the label, the formula affects neither the contraceptive pill nor high blood pressure. The natural caffeine from 100 mg of guarana extract counts with your tea and coffee; if sensitive, take the capsule at lunch. On prescription medicines for your metabolism, ask your GP or pharmacist first. 15 mg zinc per capsule sits below the UK safe upper level of 25 mg a day.

Does Pb Sin 18 contain chromium picolinate?

Yes. Pb Sin 18 contains chromium as chromium picolinate, 40 mcg per capsule and therefore 100% of the Nutrient Reference Value, plus zinc as zinc citrate, 15 mg and therefore 150% NRV; both compounds are on the permitted list under Regulation (EC) No 1170/2009. For chromium and zinc, the authorised claims in the claims block apply. Guarana, apple cider vinegar, inulin, L-leucine and L-glutamine come in the same capsule, so there is no need to buy a chromium picolinate tablet and an apple cider vinegar capsule separately.

When is the best time to take Pb Sin 18 capsules?

One capsule a day, whole and unchewed, with two large glasses of water, 15–30 minutes before or with your lunch or dinner. If you're sensitive to caffeine, choose lunch. If swallowing is difficult, open the HPMC capsule, stir the powder into water and drink it straight away. The intake planner above combines meal, intake method and supply into your personal plan.

What is the Pb Sin 18 price in the UK?

£55.00 for the 30-day supply (plus £4.95 delivery, £2.00 per day including delivery), £82.95 for 60 days (free delivery, £1.38 per day) and £109.95 for 90 days (free delivery, only £1.22 per day, Best Seller). Pay with Klarna, Google Pay, Apple Pay, Visa, Mastercard, PayPal or American Express. Every order comes with a 60-Day Money-Back Guarantee plus your 14-day statutory right to cancel.
