Absolutely! We have tons of customers who are not on hormonal birth control that have had amazing results using Top Up Tonic. It’s a really great supplement to support your thyroid and overall health. Hypothyroid contributes to weight gain by slowing down metabolism. Top Up Tonic’s formulation is fantastic for supporting your thyroid. It contains iodine, zinc, and selenium—which are all really important for supporting an under-active thyroid. And the probiotics in Top Up Tonic are beneficial for gut health—having an optimally functioning digestive tract is important for the absorption of key nutrients, too.
