PB SIN 18 ingredients: the full list per capsule
Every pb-sin 18 capsule carries the same seven active ingredients, and the official table gives an exact amount for each one. This is the daily dose, because you only ever take one capsule a day:
- Guarana extract (Paullinia cupana) – 100 mg
- Apple cider vinegar extract – 100 mg
- Inulin powder from Jerusalem artichoke – 100 mg
- L-Leucine – 50 mg
- L-Glutamine – 50 mg
- Zinc (as zinc citrate) – 15 mg, 150% NRV
- Chromium (as chromium picolinate) – 40 µg, 100% NRV
The full ingredient line on the box also names the capsule shell, hydroxypropylmethylcellulose (HPMC), and one anticaking agent, E470 b. That is the complete recipe – no long list of fillers, which is why the official site describes the formula as natural and free from additives. Each pack holds 30 capsules, so one pack is exactly one month of the PB SIN 18 dosage.

Guarana, apple cider vinegar and inulin explained
Guarana extract – 100 mg
Guarana is a climbing plant from the Amazon, and its seeds are the source of this extract. Guarana naturally contains caffeine, which is why many people prefer to take their capsule with lunch rather than late in the evening.
Apple cider vinegar extract – 100 mg
Apple cider vinegar is made by fermenting apple juice. In PB SIN 18 it comes as a dry extract inside the capsule, so you get it without the sharp taste of drinking vinegar from a spoon.
Inulin from Jerusalem artichoke – 100 mg
Inulin is a natural dietary fibre. In pb-sin 18 it is taken from the root of the Jerusalem artichoke, a knobbly tuber related to the sunflower. It is a plant fibre, nothing more exotic than that, and it makes up a full 100 mg of every capsule.

L-Leucine – 50 mg
L-Leucine is an amino acid, one of the building blocks of protein, and it is found in everyday foods such as meat, dairy and pulses.
L-Glutamine – 50 mg
L-Glutamine is also an amino acid and is one of the most common ones in the body.
Zinc – 15 mg (150% NRV)
Zinc is an essential mineral. It carries an authorised claim: zinc contributes to normal macronutrient metabolism and to normal acid-base metabolism. One capsule gives 150% of the nutrient reference value.
Chromium – 40 µg (100% NRV)
Chromium is a trace mineral, used here in the picolinate form. Its authorised claims: chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels. One capsule covers 100% of the NRV.

PB SIN 18 dosage: how to take pb sin 18 each day
The official PB SIN 18 dosage is one capsule, once a day. That is all – no doubling up, no complicated schedule. The official usage page sets it out like this:
- Take one (1) capsule once daily.
- Swallow it whole and unchewed.
- Drink two large glasses of water with it.
- Take it roughly 15 to 30 minutes before, or directly with, a meal – lunch or dinner.
Because one pack contains 30 capsules, a single pack lasts a month, two packs last 60 days and the 3-pack covers a full 90 days. That is why the 90-day supply is the natural fit for anyone who wants to take PB SIN 18 properly and steadily rather than stopping after a few weeks.

Lunch or dinner?
Either works – the usage page simply says before or with lunch or dinner. Since guarana naturally contains caffeine, lunchtime may suit you better if you are sensitive to caffeine. Pick one meal and keep to it so the capsule becomes a habit.
Why two large glasses of water?
The inulin in each capsule is a fibre, and the official instruction pairs every capsule with two large glasses of water. Do not skip them.
Can't swallow capsules?
No problem. The usage page says a capsule can be opened and the contents mixed with water and drunk. The capsule shell is HPMC, so it opens easily.
Forgot a day?
Simply carry on with one capsule at your next lunch or dinner. The dose is one capsule daily – never two to catch up.
Pregnancy, medication and under-18s: ask your doctor
PB SIN 18 is a food supplement in capsule form, not a medicine, and the official usage page is clear about the few things to know:
- It has no effect on the contraceptive pill.
- It has no effect on high blood pressure.
