Report overview
Niacin · 50 mg OverallScore66
A Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyF Value
Liver Guard provides 50 mg of niacin to support metabolic health alongside liver-specific nutrients. It is a targeted formula that utilizes quality ingredients but lacks transparency regarding the niacin form. The cost per serving is on the high side for Vitamin B3 alone.
C+ Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value
Source Naturals Liver Guard provides a small inclusion of choline bitartrate alongside herbal extracts for liver support. While it supports general metabolic health, it is not a potent or cost-effective source of choline on its own. It is a clean formulation but provides very little elemental choline per serving.
Coenzyme Q-10 · 12 mg OverallScore35
F Active Ingredient Quality & BioavailabilityD Dose, Safety & Label TransparencyC Value
This liver-support formula contains only 12 mg of CoQ10 per serving. It is not an appropriate supplement for those specifically looking for the heart health benefits of coenzyme Q-10.
