Nature's Sunshine uses natural source materials that are subject to color variation.

Master gland Provides a blend of herbs, vitamins, minerals and other nutrients that help balance the glandular system, particularly supporting the pituitary, thyroid and adrenal glands. Adaptamax Features a combination of adaptogenic herbs that are known to help the body combat and adapt to stressful situations, and supports energy levels and sexual drive. Adrenal support Contains a blend of vitamins, minerals, enzymes and adaptogenic herbs to support and strengthen the adrenal glands, which in turn helps the body to better adapt to stressful situations.

Supports the body's glandular functions Glandular system support

The glandular system regulates voluntary and involuntary action within the body such as growth, metabolism, digestion, elimination, activity and sleep. Endocrine and exocrine glands secrete fluids and hormones either to a duct or directly into the bloodstream where they stimulate some type of action. The ingredients in this 30-day Glandular System program are formulated to support balance and nourishment to the body's complex glandular system.
