PB SIN 18 side effects: the official list
When people search “pb sin 18 side effects”, they want the facts the manufacturer itself publishes, not guesswork. The official usage page for pb-sin® 18 has a short section headed “Side Effects”. Here it is, point by point, in plain English:
- Dry mouth – listed as a side effect known in rare cases, which may affect up to 1 in 1,000 users.
- The contraceptive pill – taking the product has no effect on it.
- High blood pressure – taking the product has no effect on it.
- Driving and machinery – during use you can drive and operate machinery as normal.
- Existing conditions – please discuss any pre-existing medical condition with your treating doctor.
That is the complete official list. We have not added to it, shortened it or softened it, and we do not publish user stories about side effects because none come with the product information. If you see claims elsewhere that go beyond these points, they are not the shop's words.
Is PB SIN 18 safe? How to read the official answer
“Is PB SIN 18 safe?” deserves an honest answer, and it has two parts. First, what the product is: PB SIN 18 is a food supplement in capsule form, not a medicine. It is sold as a food supplement, the box says so, and it carries no medicinal claim. Its statements have not been evaluated by the Food Standards Agency.
Second, what the label asks of you. The official disclaimer says the product is not recommended for anyone under 18 and asks you to consult your doctor before taking it, particularly if you are pregnant, breastfeeding, taking medication or suffering from a medical condition. Those are the shop's own conditions of use, and they are the right starting point for anyone weighing up whether PB SIN 18 suits them personally.
No supplement can promise to suit every single person, and this page will not pretend otherwise. What you can do is check the ingredients against your own situation, follow the dose exactly and talk to your GP if any of the points below apply to you. For the wider question of whether the shop itself is genuine, see pb sin 18 legit.

The official wording names the groups below. If you belong to any of them, book a word with your GP or pharmacist before your first capsule:
Under-18s
The product is not recommended for persons under 18 years of age. This is the one group the label rules out rather than referring to a doctor.
Pregnancy and breastfeeding
The disclaimer specifically asks anyone who is pregnant or breastfeeding to consult a doctor before taking it.
Anyone taking medication
If you take any prescribed or over-the-counter medicine, show your doctor the full ingredient list below and ask before you start.
Anyone with a medical condition
The usage page asks you to discuss any pre-existing medical condition with your treating doctor.
Guarana and caffeine: worth knowing
One of the seven ingredients is guarana extract (Paullinia cupana), 100 mg per capsule. Guarana naturally contains caffeine. The official pages do not list caffeine as a side effect, but it is a fact about the ingredient that you should know before you start.
If you are sensitive to caffeine, or you already drink a lot of coffee, tea or energy drinks, mention guarana and its caffeine to your doctor, especially if you have been told to limit caffeine for any reason.
Everything else in the formula is listed openly, with an amount for each ingredient. You will find the full breakdown, ingredient by ingredient, on our page about pb sin 18 ingredients.

Claim 46% off →The full ingredient line, to check against your own needs
If you have an allergy, an intolerance or simply a list of things you avoid, the official ingredient line is what to check. In label order, one capsule contains:
- Guarana extract (Paullinia cupana) – 100 mg
- Apple cider vinegar extract – 100 mg
- Inulin powder from Jerusalem artichoke – 100 mg
- Hydroxypropylmethylcellulose capsule (HPMC) – the capsule shell
- L-Leucine – 50 mg
- L-Glutamine – 50 mg
- Zinc (citrate) – 15 mg, 150% NRV
- Anticaking agent (E470 b)
- Chromium (picolinate) – 40 µg, 100% NRV
Zinc contributes to normal macronutrient metabolism and to normal acid-base metabolism; chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels. Those are the authorised nutrient claims, and the only ones the product carries. If any line on that list is something you have been told to avoid, ask your doctor before ordering.
Taking it exactly as directed
Following the dose is part of using any supplement sensibly, and the official usage page is precise:
- One capsule, once a day – whole and unchewed.
- Two large glasses of water with it, every time.
- 15 to 30 minutes before, or directly with, a meal – lunch or dinner.
- Can't swallow capsules? One can be opened and the contents mixed with water and drunk.
The zinc and chromium amounts are set for that single daily capsule, so there is no reason to double up, and doing so would not follow the instructions. The two glasses of water are part of the official dose, not an optional extra – drink them with the capsule. A 30-capsule pack lasts exactly a month at this dose. If you are wondering what the product can and cannot claim beyond this, our page answering does pb sin 18 work covers it plainly.
Every pack comes with a 60-day money-back guarantee and secure payment.
