泛酸（維生素 B5） Vitamin B5 (Pantothenic acid) × 高膽固醇／血脂異常

結論：證據支持但有警示

降血脂證據全屬「泛硫乙胺 pantethine」（B5 雙硫衍生物），非一般泛酸。

降血脂證據全屬「泛硫乙胺 pantethine」（B5 雙硫衍生物），非一般泛酸。

可用人體資料僅 Evans 2014（n=24 完成，LDL −11%）、Rumberger 2011（n=120）兩個小型雙盲 RCT 加 McRae 2005 舊式回顧（LDL −20%），樣本小、逾半廠商贊助（Daiichi/Kyowa，Pantesin 製造商）、舊試驗品質低，效果幅度溫和且現代 RCT 三酸甘油酯未見顯著改善。

機轉合理但缺乏獨立高品質 MA 與學會 first-line 背書，符合「薄弱證據」C 級；對『泛酸本身』則為 U（無效）。

Pantethine, a derivative of vitamin B5, favorably alters total, LDL and non-HDL cholesterol in low to moderate CV risk subjects eligible for statin therapy
PMID: 24600231 2014 RCT (double-blind) n = 32
結論：Pantethine cut LDL-C 11% from baseline vs +3% placebo (P=0.006 at wk16); TC -6% (P=0.040), non-HDL -8% (P=0.042); triglycerides not significantly changed.

PMID: 21925346 2011 RCT (double-blind) n = 120
結論：By wk16 pantethine gave an additional ~6 mg/dL TC reduction and ~4 mg/dL extra decrease in both LDL-C and apoB vs placebo on a TLC diet; modest but favorable.

On the basis of the data presented, the Panel concludes that a cause and effect relationship has been established between the dietary intake of pantothenic acid and a normal energy-yielding metabolism, normal synthesis and metabolism of steroid hormones, vitamin D and some neurotransmitters, normal mental performance and the reduction of tiredness and fatigue. 來源↗

Pantothenic acid has several functions, such as helping our bodies release energy from food. Pantothenic acid is found in virtually all meat and vegetables... As pantothenic acid is found in a wide range of foods, it's unlikely that you'll not get enough of it. You should be able to get all the pantothenic acid you need by eating a varied and balanced diet. 來源↗

Because some pantothenic acid is present in almost all foods, deficiency is rare except in people with severe malnutrition. [...] The FNB was unable to establish ULs for pantothenic acid because there are no reports of pantothenic acid toxicity in humans at high intakes. [...] Pantothenic acid is not known to have any clinically relevant interactions with medications. 來源↗

Pantothenic acid is part of the vitamin B family. It is used to treat or prevent vitamin B5 deficiency. Pantethine, a derivative of pantothenic acid, has been studied for lowering cholesterol and triglyceride levels, but there is not enough reliable evidence to know whether pantothenic acid itself is effective for high cholesterol. 來源↗

Because pantothenic acid helps to break down fats, it has been studied for a potential role in reducing cholesterol levels in people who have dyslipidemia... It is unclear if pantothenic acid supplements can lower blood fats independently of (or enhance the cholesterol-lowering effects of) eating a heart-healthy diet. 來源↗

台灣社群（PTT FITNESS/Doctor-Info/medstudent、Dcard、Mobile01）幾乎沒有「泛酸（維生素B5）降膽固醇/血脂」的討論；膽固醇相關串多談史他汀、飲食、紅麴與菸鹼酸(B3)，未提及B5。

💬社群實感

無共識（社群缺乏將B5/泛酸用於降膽固醇的實測討論；衍生物泛硫乙胺pantethine僅見於藥品/原料商頁面，非鄉民心得）
