not sure how to recommend since you so choosy...always go for branded one since it will be better quality and better QC for the product...don't go for cap ayam brand if you really concern on the quality... taking supplement is more like try and error...there can be everyone come in this topic and say the brand they eat is good but not guarantee it will adsorb/work well on your body...

best is to consult licensed nutritionist or the licensed pharmacist instead of asking those promoter that stand at the counter...company train them to have knowledge on their own brand and reading the script design by the marketing team..they actually know very little on what they selling~
