How are such capsules usually taken, and are there any storage requirements? — Black Walnut Hulls 500 mg, 60 capsules - Swanson

For adults, 1 capsule 1–2 times a day is recommended, taken with water (up to 1000 mg, that is 2 capsules a day); do not exceed the recommended dose. The supplement must not be used in place of a varied diet.

The capsule form is convenient because it does not have the pronounced taste and smell of the hull that is typical of powders or infusions, which is especially relevant for those who are sensitive to the bitterness of plant extracts.

As for storage: herbal powders in capsules are sensitive to moisture and heat. The standard recommendations are to keep the bottle tightly closed, in a cool, dry place, away from direct sunlight. Do not store it in the bathroom or next to the stove. The exact storage conditions and shelf life are given on the packaging; it is worth checking them at the time of purchase and following them throughout use.
