Hold the dose under your tongue for a few moments, then swallow, or take it in a little water, juice or hot tea. The regular adult dose is two droppers full (1.5 ml) three times a day. Step down to twice a day for maintenance, or for regulating and fortifying the organ system the formula is built for. One full compression of the dropper bulb is a dropper full, about 0.75 ml. Each formula’s page lists its exact dose.

Zoi formulas work for immediate needs as well as long-term support. The regular adult dose is three times a day, stepping down to twice a day for maintenance. For acute needs, the general pattern is 3–4 doses a day, and each formula’s “How to use” section gives its own acute pattern. Allergy Relief · Atsáli, for example, can be taken every 20–25 minutes, up to 3 times in a row, for a more pronounced set of seasonal allergy symptoms.

Zoi formulas are fast-acting: many people feel a change within 15 minutes of a dose, and most notice a difference within days. The building formulas, the Organ Meridians, Longevity and Resilience, show their best results after four to six weeks of steady use. Consistency matters more than the size of the dose.

Yes. Most people pair a Zoi Modern for what has come up with the Organ Meridian underneath it, and our duos and trios are built that way. Take them at the same time or spaced through the day. Stay within the standard dose of each.

Most Zoi formulas give a child dose for children 30 to 100 lb: one dropper full, three times a day, stepping down to twice a day for maintenance. For children under 30 lb, it is good to ask a practitioner, and take caution if your child has shown allergies to common foods.

A 2 fl oz (60 ml) bottle holds 40 standard doses. At two droppers full three times a day it lasts about 13 days; at the twice-daily maintenance dose, about 20 days. Store it at room temperature, out of direct sunlight, and keep each dropper with its own bottle. It needs no refrigeration. Because of the alcohol, a Zoi formula doesn’t really expire, even once it’s open. Each bottle carries a 3-year expiration date so there’s one to go by. Keep it out of reach of children.

Zoi formulas contain 18.25% alcohol. A standard dose is 1.5 ml, so stirred into a cup of water it comes to less than 0.5% alcohol, about the same as a cup of kombucha or less. If alcohol is a concern, add the dose to hot tea. Most of the alcohol evaporates, and you drink it once it cools.

Herbal supplements can interact with prescribed medication. Zoi formulas are gentle, but blood thinners, blood-sugar medication, thyroid medication and immune-suppressing drugs are the ones to check.

A tincture is an herbal extract made with alcohol. The alcohol draws out plant compounds that don’t dissolve in water, such as essential oils, alkaloids and resins, and keeps the formula shelf-stable without refrigeration. Every Zoi formula is a tincture of organic, USP-certified alcohol and vegetable glycerin, taken in small doses by the dropper.

A capsule holds dried, powdered herb or a dried extract. Your stomach has to break the shell and the powder down before anything is absorbed, the dose comes in whole-capsule steps, and the compounds that only alcohol draws out, such as essential oils, alkaloids and resins, are often lost in drying. A tincture is already liquid. It is absorbed quickly, partly under the tongue, which is part of why Zoi formulas are fast-acting, and you can adjust the dose by the dropper.
