Unverified三萜类是灵芝苦味与核心活性来源，优质提取物三萜含量应≥3%；纯子实体提取物三萜含量普遍高于菌丝体，认准'子实体来源'标注78% similarUnverified灵芝多糖和三萜是两大功效指标：多糖主要调节免疫，三萜主要护肝抗炎；正规孢子粉产品应明确标注这两项含量，只笼统标'灵芝多糖体'而无具体数值的产品可信度较低76% similarUnverified灵芝(Reishi)有效活性为β-葡聚糖和三萜类，优质产品会标注β-glucan百分比(如≥25%)并说明是子实体还是菌丝体提取；菌丝体谷物培养基产品淀粉含量高、活性成分低76% similarUnverified成分表看功效成分排位：真正起效的活性物应排在前1/3至1/2（水、甘油之后），若烟酰胺/视黄醇排在防腐剂之后则浓度极低，属概念性添加75% similarUnverified葛根提取物的活性成分实测常以'葛根总黄酮/葛根总异黄酮'标注，而'葛根素'仅是其中一种成分，两者不等同——比较产品时应统一口径，警惕用总黄酮数值混淆成葛根素含量72% similar
