Viridian’s Thyroid Complex naturally contributes to a healthy thyroid function. Iodine deficiency is the most common cause of hypothyroidism. This food supplement contains iodine, as well as selenium, zinc and olive leaf extract which all contribute to a healthy thyroid function. This supplement also supports thyroid hormone conversion and also contains Vitamins B1, B2, B3 which can contribute to the reduction of tiredness and fatigue. Because the Thyroid is very sensitive to oxidative damage, so this formula contains anti-oxidants including vitamin A, selenium, zinc and olive leaf, all of which possess flavonoids with both antioxidant and anti-inflammatory properties to support thyroid function.
