Selenium Supplementation in Patients with Hashimoto Thyroiditis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials
PMID: 38243784 2024 統合分析 n = 2,358
結論：TPO-Ab significantly reduced (SMD -0.96, 95% CI -1.36 to -0.56; 29 cohorts, n=2358). Small TSH reduction in non-LT4 subgroup (SMD -0.21, 95% CI -0.43 to -0.02; n=869). MDA reduced (SMD -1.16, -2.29 to -0.02). NO significant change in fT4, T4, fT3, T3, or thyroid volume. Adverse events comparable (OR 0.89, 0.46-1.75). High heterogeneity I²=90% (TPOAb).

PMID: 40898469 2025 統合分析 n = 1,610
結論：TPO-Ab significantly reduced at 3 mo (SMD -0.46, 95% CI -0.74 to -0.18, p=0.001) and 6 mo (SMD -0.80, -1.38 to -0.21, p=0.008).

The Effects of Selenium Supplementation in the Treatment of Autoimmune Thyroiditis: An Overview of Systematic Reviews
PMID: 37513612 2023 Umbrella Review
結論：TPO-Ab significantly reduced at 3 and 6 months in BOTH LT4-treated and non-LT4-treated subgroups, BUT effect LOST at 12 months in non-LT4 group. Tg-Ab reduced only in non-LT4 at 3-6 mo, also lost at 12 mo. AMSTAR-2: only 1 of 6 SRs rated high quality. GRADE certainty: VERY LOW to LOW across all outcomes. Clinical hypothyroidism progression NOT addressed. Adverse events not significantly different.

結論：At 6 months, selenium superior on: CAS (MD -1.27, 95% CI -1.68 to -0.85, p<0.0001); GO-QOL responder rate (RR 2.54, 1.69-3.81, p<0.00001); Visual functioning (MD +10.84, 4.94-16.73, p=0.003); Psychological functioning (MD +12.76, 8.51-17.00, p<0.00001); Palpebral aperture (MD -1.49, -2.90 to -0.08, p=0.04). NO significant difference in proptosis, soft tissue involvement, ocular motility, adverse events. Effects sustained at 12 months.

Selenium may reduce the risk of certain cancers. Some scientific evidence suggests that consumption of selenium may reduce the risk of certain forms of cancer. However, FDA has determined that this evidence is limited and not conclusive. 來源↗

Selenium contributes to normal thyroid function; contributes to the normal function of the immune system; contributes to the protection of cells from oxidative stress; contributes to normal spermatogenesis; contributes to the maintenance of normal hair; contributes to the maintenance of normal nails. 來源↗

謹慎
75μg a day for men (19 to 64 years); 60μg a day for women (19 to 64 years). You should be able to get all the selenium you need by eating a varied and balanced diet that includes meat, fish or nuts. Taking 350μg or less a day of selenium supplements is unlikely to cause any harm. Too much selenium causes selenosis, a condition that, in its mildest form, can lead to loss of hair and nails. 來源↗

Selenium is a trace element that is naturally present in many foods, added to others, and available as a dietary supplement. Selenium, which is nutritionally essential for humans, is a constituent of more than two dozen selenoproteins that play critical roles in reproduction, thyroid hormone metabolism, DNA synthesis, and protection from oxidative damage and infection. 來源↗

謹慎
A balanced diet and other healthy lifestyle choices may help when you have Hashimoto's, but a specific diet alone is unlikely to reverse the changes caused by the disease. There's no evidence that following one diet in particular is an effective treatment for autoimmune disorders such as Hashimoto's thyroiditis. 來源↗

Your thyroid gland holds the highest concentration of selenium in your body. Selenium is converted into selenoproteins, which help regulate your thyroid hormones. 來源↗

PTT · Dcard · Mobile01 彙整自公開論壇討論，非統計抽樣，僅反映社群風向。

低中高
📍立場總覽

台灣 PTT/Dcard/Mobile01 對「硒專門用於甲狀腺／橋本氏／Graves」的原生討論極少。硒在保健品心得文中多半只是綜合維他命的成分之一，少有針對甲狀腺自體免疫的實測串；橋本氏／甲亢患者的 PTT 心得（GoodPregnan、Health 板）談的是 Eltroxin 等處方藥與 anti-TPO 指數，幾乎不提硒補充。社群層次唯一較有聲量的相關發言是 ChineseMed 板轉貼的「硒、維他命E抗癌沒用」新聞（屬對硒療效的質疑，且談的是防癌而非甲狀腺）。真正把「硒↔甲狀腺、補硒降抗體、一天一顆巴西堅果」串起來的內容幾乎都來自商業／專業媒體與部落格（TVBS、康健、vocus、痞客邦鄭醫師、professorlin、NutriCore），業配與導購密度高，鄉民實證信號稀薄、無共識。

💬社群實感

無共識（針對甲狀腺／橋本氏的硒補充，台灣 PTT/Dcard/Mobile01 缺乏可辨識的多人實測串；零星經驗分散，且論述主要來自商業媒體與部落格而非鄉民實證）

破解迷思 社群最常見的 4 個誤解
✕
迷思「補硒就能治好橋本氏／讓抗體歸零」
✓
事實研究僅顯示部分研究可降 TPOAb，對甲狀腺功能與長期結果無定論，社群被部落格放大成療效保證
✕
迷思「巴西堅果隨便吃多多益善，越多硒越好」
✓
事實巴西堅果硒含量極高，一天約一顆即達建議量，吃多易硒過量中毒（與抗氧化保健的直覺相悖）
✕
迷思「Graves 甲亢／眼病變補硒一定有效」
✓
事實僅輕中度 Graves 眼病變的 6 個月療程有早期改善證據，且不影響長期結果，並非泛用
✕
迷思「硒是天然抗氧化保健、有益無害」
✓
事實硒安全範圍狹窄，PTT ChineseMed 板甚至有『硒抗癌沒用、過量恐增糖尿病風險』的質疑轉貼
🩹 社群通報的副作用
  • 硒過量徵兆：掉髮、指甲脆裂、皮膚病變
  • 疲勞、焦慮
  • 口中金屬味、口臭（社群與媒體提及之硒中毒典型表現）
🏷️ 社群熱議品牌

依論壇被提及頻率，非銷售或品質排序。

  • 巴西堅果（社群中最常被當作『天然補硒』的食物，而非特定保健品品牌）
  • 硒酵母（selenium yeast）類產品（社群泛稱，未見單一品牌形成口碑共識）
  • 綜合維他命中含硒配方（鄉民多透過綜合錠攝取，未針對甲狀腺挑選單方硒）
