Coral Black Walnut

Coral Black Walnut is a dietary supplement manufactured in the USA for Coral Club. The bottle holds 90 vegetable capsules, and the directed amount is two capsules twice a day with a meal.

How the label counts

The ingredient panel is stated per 2-capsule serving, not per capsule: 600 mg of black walnut leaf extract and 100 mg of oregano leaf extract. Per single capsule that works out to 300 mg and 50 mg.

At the directed four capsules a day the daily totals are 1200 mg of black walnut leaf extract and 200 mg of oregano leaf extract, and a bottle of 90 capsules covers 22 days.

What the manufacturer states

According to Coral Club, the plant-based ingredients are traditionally used to support digestive health and help promote internal balance, and the active components support the body's natural detoxification and elimination processes, contributing to a clean digestive environment, gut comfort and an overall sense of vitality.*

• Black walnut leaves — from Juglans nigra, a tree native to North America. The card names juglone, a naphthoquinone, as a key active compound, known for its enzyme-inhibiting properties and its role in supporting internal balance.*
• Oregano leaves — contain rosmarinic acid, which helps manage oxidative stress by neutralizing free radicals and supports immune system function; carvacrol and thymol are named as two phytochemicals that support the body's detoxification processes.*

If you have a tree nut allergy, read this first

The extract is made from the leaves of the black walnut, not from the nut, and the card carries no tree nut allergen statement. Even so, walnut is one of the nine major food allergens recognized in the United States, and anyone with a diagnosed walnut or pecan allergy should confirm the sourcing and manufacturing arrangements with Coral Club before taking the product.

One of the other ingredients is coconut powder, which the FDA also classifies as a tree nut for labeling purposes.

On the length of a course

The US card sets no maximum course length. Worth noting that a bottle lasts about three weeks at the directed amount, and that the Romanian label for the same product caps a course at one month, citing the juglone content. Whatever the reason for the difference between markets, taking the product for months on end is not something the label supports, and a practitioner is the right person to ask about repeating courses.
