On sunny summer days around June 24, St. John's wort blooms profusely along roadsides and field edges, with its characteristic yellow flowers. This plant, botanically known as Hypericum perforatum, has been used in herbal tradition for centuries and is now a familiar ingredient in the supplement cabinet. Vit4ever processes the extract in a concentrated form: 500 mg per capsule, obtained from a 10:1 extraction process. This means that 5000 mg of dried St. John's wort is needed to make one capsule. A bottle contains 240 capsules, enough for eight months at an intake of 1 capsule per day.
It is important to know that St. John's wort is an herb with a pronounced profile. That makes it interesting to understand, but it also requires caution when combined with medication. Further down on this page you will read more about this in the safety advice.
St. John's wort naturally contains a group of substances called hypericins, along with flavonoids and hyperforin. Vit4ever standardizes the extract to 0.3% hypericin, which means that each capsule contains a uniform and measurable amount of this group of substances. The difference between a non-standardized herbal powder and this extract lies in that consistency: with an ordinary dried herb, the composition can differ per harvest, while a standardized extract remains comparable per capsule. Manufacturers use this approach more often with plant extracts, because the concentration of plant substances in nature can naturally fluctuate due to soil, climate, and harvest time. In addition to hypericin, the herb also contains hyperforin, another group of substances that naturally occurs in the flowers and leaves of the plant, and small amounts of flavonoids such as quercetin and rutin, which are also found in many other plants.
The designation 10:1 tells something about the ratio between raw material and final product. With this extract, 10 kilos of fresh or dried St. John's wort have been reduced to 1 kilo of extract, by soaking the herb, filtering it, and evaporating the liquid into a concentrated powder. What remains is a concentrated extract in which the plant substances are closer together than in the unprocessed herb. Many people think that 'extract' automatically means 'stronger', but it is mainly about concentration: less volume needed for the same amount of plant substances. Because of this, a large dose of dried herb fits in a single, manageable capsule instead of a handful of dried flowers that you would have to weigh and dose yourself. That makes intake in practice a lot easier, without having to tinker with tea bags or tinctures yourself.
Hypericum perforatum owes its Dutch name to the blooming period around the name day of John the Baptist, at the end of June. Anyone who holds a leaf up to the light sees small, translucent dots: that is what the species name 'perforatum' refers to, which means 'perforated', even though there is actually no hole in the leaf. Those glands contain the oils and hypericins for which the plant is known. In the wild, St. John's wort grows in dry, sunny places in large parts of Europe, from roadsides to forest edges, and it is now also cultivated for extraction purposes. Vit4ever uses exclusively the extract of the above-ground part of the plant for this product, so the flowers, leaves, and fine stems, processed into a fine powder that is filled into a plant-based capsule.
The capsule wall of this product consists of hydroxypropyl methylcellulose, a plant-based raw material that is often used as an alternative to gelatin. Therefore, this product is suitable for people who eat vegan or vegetarian. In addition to the extract, the capsule wall, and an anti-caking agent, there are no artificial colors, flavors, or unnecessary fillers. Anyone who pays attention to what is in a supplement will see a short and clear list here: the extract itself, the coating, and stearic acid as an anti-caking agent. That makes it easy to check exactly what you are getting in with every capsule, without fine print or unknown additives on the label.
St. John's wort is an herb that has been collected and processed for generations, and that now returns in a modern, standardized form in these capsules. It is precisely because of that pronounced nature that caution during use matters. Therefore, always read the recommended dosage and the safety advice on this page, especially if you use other products, herbs, or medication.

Yes, the capsule shell is made from hydroxypropyl methylcellulose, a plant-based alternative to gelatin, and the extract contains no animal ingredients.
Not without consultation. St. John's Wort is known to affect the efficacy of various medications. Therefore, always consult a doctor or pharmacist first if you are taking medication, and do not combine this product with other herbal preparations without advice.
An extract makes the concentration of plant compounds, such as hypericin, measurable and consistent per capsule. With loose dried herb, that concentration can vary from harvest to harvest and batch to batch, due to the influence of soil, climate, and time of harvest.
A 10:1 extract means that 10 kilos of raw material have been reduced to 1 kilo of concentrated extract. As a result, a single 500 mg extract capsule contains an amount of plant compounds equivalent to 5000 mg of dried herb, without you having to weigh or dose it yourself.
