最沒有效的前 10 種營養補充劑

The least effective nutritional supplements can be subjective and depend on a variety of factors, such as personal health needs, supplement quality and scientific evidence. However, the following ten nutritional supplements may not always provide significant benefits or have limited scientific support:

Weight Loss Supplements:

Many weight loss supplements claim to boost fat burning or suppress appetite, but often lack strong scientific evidence to support their effectiveness. Some may even pose health risks due to ingredients such as stimulants or herbal extracts.

Hair Growth Supplements:

Supplements for hair growth may contain vitamins, minerals or herbal extracts, but the evidence supporting their efficacy is often weak. Hair health is affected by many factors, and supplements alone may not address the underlying cause of hair loss or promote significant growth.

Detox supplements:

Detox or cleanse supplements claim to remove toxins from the body and promote overall health, but there is limited evidence to support their efficacy. The body has its own detoxification system, mainly the liver and kidneys, which can effectively eliminate toxins.

Memory and Brain Health Supplements:

While some supplements claim to improve memory, concentration, or cognitive function, scientific evidence to support their effectiveness is often lacking. Common ingredients such as ginkgo biloba or herbal blends may not provide significant cognitive benefits to healthy individuals.

Collagen Supplements:

Collagen supplements are marketed to promote skin health, joint health, and anti-aging benefits. While collagen is essential for connective tissue health, the evidence supporting the benefits of collagen supplements is mixed, and absorption rates may vary.

Energy supplements:

Supplements used to boost energy and vitality often contain stimulants such as caffeine or herbal extracts. While these ingredients may provide a temporary energy boost, relying on energy supplements may mask underlying fatigue or sleep issues.

Testosterone Boosters:

Testosterone-boosting supplements claim to enhance muscle growth, libido, and energy, especially in older men. However, evidence to support its efficacy is limited, and some ingredients may pose risks or have little effect on testosterone levels.

Joint Health Supplements:

Supplements containing glucosamine, chondroitin, or MSM are often used to promote joint health and reduce arthritis symptoms. While some studies suggest potential benefits for some individuals, the overall evidence is mixed and results may vary.

Immune-boosting supplements:

Supplements containing vitamins, minerals, or herbal extracts claim to strengthen the immune system and prevent disease. While adequate nutrition is critical for immune function, there is limited evidence that supplements alone can significantly enhance immune responses or prevent infection.

Colon Cleansing Supplements:

Colon cleansing or colon detox supplements claim to remove accumulated toxins and waste products from the colon. However, there is little scientific evidence to support their efficacy, and they may cause side effects such as dehydration or electrolyte imbalance.

It is important to note that individual responses to supplements may vary and it is recommended to consult a healthcare professional before starting any new supplement regimen, especially for those with underlying health conditions or who are taking medications. Additionally, choosing supplements from reputable brands and manufacturers that adhere to quality standards can help ensure safety and effectiveness.

前言:點解中餐炒肉咁滑? 好多香港人炒肉嘅時候都會發現,餐廳啲雞絲牛柳炒出嚟特別滑溜、唔鞋口。呢個秘密,唔喺高級食材,而係一個平凡但強大嘅材料——粟粉(Cornstarch)。 呢種技巧叫做**「走油前醃」或「滑油醃肉法」(Velveting)**,係中餐獨有技術之一,主要靠粟粉、蛋白、調味料...
咩係三價鐵(Fe³⁺)同二價鐵(Fe²⁺)?

咩係三價鐵(Fe³⁺)同二價鐵(Fe²⁺)?

當我哋講「鐵質」時,唔止係話有冇攝取足夠,而係講緊鐵喺人體內唔同形態(尤其係三價鐵 Fe³⁺ 同二價鐵 Fe²⁺)點樣被吸收、轉化、運輸同儲存,呢啲都深深影響生物可利用率

全面解構低鐵原因、病理機制及影響

全面解構低鐵原因、病理機制及影響

低鐵唔止係營養問題,仲可能係身體慢性警號

鐵質(iron)係人體不可或缺嘅微量元素,主要負責攜帶氧氣嘅血紅素(hemoglobin)製造、能量代謝、免疫調節等。當鐵質長期攝取不足、吸收差、或失去過多,就會導致「低鐵」(iron deficiency)甚至發展成「缺鐵性貧血」(iron deficiency anemia)。本文將從臨床醫學與分子生理角度,深入探討低鐵嘅成因、病理機制、生物轉化過程,以及其對人體造成嘅連鎖影響。

夢遺係唔係一定關性事?

夢遺,即係在無意識之下於睡眠中射精,係一種常見於青春期男生甚至成年男性身上的自然生理現象。夢遺唔等於一定發生性夢,也唔等於有性慾過強。它與睡眠週期中快速動眼期(REM sleep)嘅勃起模式有關,亦可能反映正常的荷爾蒙波動及精液排出節律。 咩係夢遺? 夢遺(nocturnal emission...

唔凍都會打冷震?

打冷震(shivering)唔一定因為天氣凍,喺情緒波動、發燒初期、焦慮、緊張等情況下都可以出現。打冷震係一種由大腦下視丘控制嘅「非意識性肌肉收縮」,目的係維持或調節核心體溫或應對突發壓力。了解打冷震背後嘅神經與體溫調節原理,可以幫我哋區分「正常生理反應」同「潛在疾病警號」。 打冷震係乜回事...
一緊張就流手汗?

一緊張就流手汗?

手掌汗腺主要受交感神經系統控制。當人面對壓力、驚訝、社交場合等刺激時,大腦會啟動「戰鬥或逃跑反應」,促使手掌、腳底等部位產生明顯出汗。這種情況屬於精神性出汗,與溫度無直接關係,係身體對外在壓力的自然反應。

起身「眼前一黑」係咩事?

當你由坐或瞓姿突然企起,血液未能即時供應足夠氧氣到腦部,形成姿勢性低血壓(orthostatic hypotension),導致短暫性視野模糊、頭暈甚至站立不穩。青少年、長者、飲水不足或患有自律神經功能障礙人士較常出現。

瞓覺點解會流口水?

唾液分泌受副交感神經控制,當身體進入深層睡眠並肌肉放鬆時,容易出現流口水現象,尤其側睡或口微開者更明顯。
