Get to know the active ingredients of the Best B-Complex supplement

Recommended intake: shake before use. Dissolve the dose of 15 ml in 100 ml of water, mix and drink. Take after a large meal. The product contains vitamin B3, which when taken on an empty stomach can cause the so-called niacin flush, i.e. dilation of blood vessels, manifested by redness and burning of the skin. Using the product after a meal reduces the flush effect.

Storage: at room temperature, in a dry place, out of reach of small children. Protect from moisture and light. Once opened, store in the refrigerator. Use within 5 weeks.

Precautions: do not exceed the recommended daily dose. A dietary supplement cannot be used as a substitute for a varied diet. The product is not intended for use by children, pregnant or breastfeeding women. People taking medicinal products should consult a doctor before use.

Where are BestLab dietary supplements manufactured?

BestLab supplements are manufactured in Poland, in modern plants that meet the highest quality standards. The production process is carried out using advanced technologies that guarantee the preservation of the full nutritional value of active ingredients. The raw materials from which our supplements are made come from various regions of the world – we select only those that meet our rigorous requirements for purity, effectiveness, and quality. This gives us the confidence that every product that ends up in your hands is completely safe and effective.

Have BestLab supplements been tested?

Yes, each batch of BestLab supplements undergoes detailed testing at the independent research facility JS Hamilton, a renowned certification center in Poland. These supplements are tested for purity, composition, and active substance content to ensure their highest quality and safety of use. We only use standardized raw materials, which means that each capsule contains the exact amount of active ingredients declared on the label. Additionally, our products are free from artificial fillers, preservatives, and dyes, which makes them even more healthy.

Does Best B-Complex contain gluten? Can it be used by people with celiac disease?

Our supplements are completely gluten-free, which means they can be safely used by people with celiac disease and those who avoid gluten for other health reasons. We make every effort to ensure that our products are as pure and natural as possible, which is why you will not find any unnecessary fillers, preservatives, or artificial colors in their composition. Additionally, each batch is tested for the presence of gluten and lactose to ensure complete safety of use even for people with the most sensitive digestive system.

Can B-Complex be used during pregnancy?

The vast majority of BestLab supplements are safe to use during pregnancy, except for InsuBest and BestBody products. Supplementation during this special time can support the health of the mother and the development of the baby, however, for your safety, we always recommend consulting your doctor before taking any dietary supplement.

Can B-Complex be used while breastfeeding?

As with pregnancy, most BestLab supplements can be safely used by breastfeeding women, except for InsuBest and BestBody products. Breastfeeding is an important time when the need for certain nutrients increases, so supplementation can be helpful. However, for your health and the health of your baby, we always recommend consulting a doctor before using supplements.

After taking B-Complex my skin became red and burning, does this mean I have an allergy?

This is a phenomenon described as flushing and is caused by the high content of niacin (vitamin B3) in the product. It is not a symptom of allergy or a contraindication to use the product.

Very unpalatable and the information, in small print, to store in the fridge after opening. Headache, dizziness after consumption. Maybe because of these artificial colourings.

Good morning, after about 2 weeks my stomach started reacting with excessive acid secretion and it's as if it's nervous. Because my stomach once contracted in my youth, I pay attention to what I eat, meaning mostly cooked dishes and easily digestible meals. Sometimes I eat something that might cause excessive acid secretion, but that's very sporadic and only when I know my stomach is calm.

Very good composition, including folic acid, which I need to increase to lower histamine levels and support the reduction of LDL cholesterol. Whether it will help is difficult to say before the blood test, what I intend to do after using 1.5 bottles.

The B vitamin complex is ideal/excellent!!!! It's a shame it's flavoured. Many people now have histamine problems, and citrus unfortunately exacerbates this (a headache started 30 mins later). Most people are now looking for clean ingredients, though. I hope there will be an identical, but unflavoured, version :)
