Nettle Hist-Tone™ provides targeted support for healthy mast cell function and histamine balance. When seasonal or environmental challenges arise, the body's immune response can become overactive. This formula combines nettle extract with quercetin and other bioflavonoids to promote balanced mast cell activity and a normal inflammatory response. Nettle delivers vitamins, minerals, and naturally occurring flavonoids that support antioxidant status and help maintain normal histamine levels.* Non-drowsy and gentle enough for daily use, Nettle Hist-Tone™ helps maintain normal respiratory function and balanced immune response during periods of environmental stress.*
