Active Ingredients

Eight ingredients across the line.

Pentrexylin syrups stack five immune-support actives. Pentrexylin Xtra Forte capsules combine three hepatic-support botanicals. Each ingredient is paired with a clear purpose, and badges show which products contain what.

Adult Kids
Vitamin C (Ascorbic Acid)
Antioxidant · Immune Support/ Antioxidante
Water-soluble vitamin essential for normal immune function and a key antioxidant. Each 5 mL serving in both syrups delivers 50 mg — over half the daily value.
Adult Kids
Zinc Gluconate
Mineral · Immune Function/ Mineral Esencial
Trace mineral that contributes to normal immune-system function and cell division. 5 mg per serving in gluconate form, well-absorbed and gentle on the stomach.
Adult Kids
Echinacea purpurea
Botanical · Root Extract/ Extracto de Raíz
Traditional immune-support botanical. The dry root extract concentrates phenolic compounds and is one of the most-studied herbal ingredients in the wellness category. 100 mg per serving.
Adult Kids
Black Elderberry
Sambucus nigra · Fruit Extract/ Extracto de Saúco
Dark berry rich in anthocyanins and traditionally associated with cold-and-flu season wellness. 175 mg of dry fruit extract per serving — a hero ingredient on the Kids box.
Adult Kids
Propolis
Resinous Bee Compound/ Própolis
A natural resinous mixture produced by honey bees, used for centuries in traditional wellness. 25 mg per serving complements the syrups' immune-support stack.
Capsules
Milk Thistle
Botanical · Hepatic Support/ Cardo Mariano
Silybum marianum — the seed extract is the source of silymarin, a complex of flavonolignans associated with traditional liver and hepatic support.
Capsules
Reishi Mushroom
Adaptogenic Mushroom/ Hongo Reishi
Ganoderma lucidum — used in traditional Asian wellness for centuries. The fruiting-body extract is rich in polysaccharides and triterpenes.
Capsules
Silimarin
Standardized Flavonolignan/ Silimarina
Standardized active compound from milk thistle. Pairs synergistically with the whole-extract milk thistle and reishi for the capsule's hepatic-support stack.
What They Support

Pick by need.

Pentrexylin syrups are designed for daily immune support across the family. Pentrexylin Xtra Forte capsules are designed for adult hepatic and liver support. They work side by side, not interchangeably.

Directions

How to take it.

Always read the Supplement Facts panel and directions on each carton before use. Adult, Kids, and Capsule formulas are calibrated separately — match the product to the person.

1
Pick the right product
Daily immune support → Pentrexylin syrup (Adult or Kids 7+). Hepatic support for adults → Pentrexylin Xtra Forte capsules. Don't substitute — formulas and dosing differ.
2
Use the included measuring cup (syrups)
Both syrups include a dosing cup. Don't substitute a kitchen spoon — they vary in size. For capsules: take with water as directed on the carton.
3
Follow the label dose
Refer to "Directions for Use" on each carton for daily serving size and frequency by age. Do not exceed the suggested daily amount.
4
Store properly
Keep tightly closed in a cool, dry place. Use within 30 days after opening (syrups). Refrigerate after opening for best quality.
