I switched to Magnesium Breakthrough…
I switched to Magnesium Breakthrough from another brand that I was using for years. It is excellent! Has helped to significantly reduce my restless legs at night and as a result I’ve been sleeping so much better. I also started using CogniBiotics and prefer them over other probiotics. On top of high product quality, customer service was top notch with a quick resolution to a shipping issue. Really glad I found BiOptimizers!
