Thorne FloraMend Prime Probiotic review

Thorne FloraMend Prime stands out for what it was studied for. The page says a study on its three-strain blend, Lactobacillus gasseri KS-13, Bifidobacterium longum MM-2 and Bifidobacterium bifidum G9-1, found a nearly 5 percent average reduction in visceral and subcutaneous body fat, with matching effects on weight, waist circumference and BMI. Each capsule delivers 5 billion live cells through expiration in an acid and moisture resistant capsule, needs no refrigeration and is free from dairy, gluten and soy. The dose is one capsule a day with a meal. A 30-capsule bottle costs $56, or $50.40 on a 10% subscription, and Thorne accepts FSA and HSA funds through Truemed. That is more than double Renew Life's monthly price for a lower cell count and a proprietary blend that hides the amount of each strain, so it makes sense mainly for buyers drawn to the weight management research.
