A product I have found beneficial in staying above the wellness line is Inner Defense.
Inner Defense™ reinforces systemic defenses, creates unfriendly terrain for yeast and fungus, promotes healthy respiratory function, and contains potent essential oils such as Oregano, Thyme, and Thieves®, which are rich in thymol, carvacrol, and eugenol for immune support. The liquid soft gels dissolve quickly for maximum results. The soft gel capsules are formulated with fish gelatin to remove the need for carrageenan and beeswax.
Take 1 soft gel daily (a.m.) or take 1 soft gel 3-5 times daily when needed.
For best results use a probiotic 8 hours later, such as MightyPro.
