Both Purtia Capsule and Purtia Plus Capsule are nutritional supplements, but their ingredient profiles differ: regular Purtia usually contains CoQ10 along with green tea or grape seed extracts, whereas Purtia Plus contains additional nutrients like L-arginine, omega-3 fatty acids, selenium, and zinc. Therefore, you should consult your doctor to determine whether plain Purtia is suitable for your needs rather than just replacing Purtia with Purtia-Plus.
