生物素對健康有什麼好處?

What are the health benefits of biotin?

Biotin has many health benefits. Biotin helps convert carbohydrates, fats, and proteins in food into energy that your body needs.
It is responsible for forming the foundation of skin and hair cells, and some research suggests that taking biotin supplements may help improve nail strength and condition.

How much biotin do you need?

As with most essential nutrients, the amount of biotin you need each day depends on whether you are male or female and your stage of life.

age Biotin – Adequate Intake (AI)*
1 to 3 years
4 to 8 years
8 mcg/day
12 mcg/day
boy
9 to 13 years old
14 to 18 years old

20 mcg/day
30 mcg/day
girl
9 to 13 years old
14 to 18 years old

20 mcg/day
25 mcg/day
male
19+

30 mcg/day


Females over 19 years old
- Pregnant
- Lactation


25 mcg/day
30 mcg/day
35 mcg/day

Foods rich in biotin include organ meats, such as liver, but many other foods, including meat, fish, seeds and nuts, and certain vegetables, also contain biotin, but in lower amounts. For example:
food Biotin content
Beef liver (85g, cooked) 30.8 micrograms
1 egg 10 micrograms
Canned salmon (85 grams) 5 micrograms
Pork chop (85g, cooked) 3.8 micrograms
Sunflower seeds (1/4 cup, toasted) 2.6 micrograms
Sweet potatoes (1/2 cup, cooked) 2.4 micrograms
Spinach (1 cup, cooked) 1 microgram

Other sources include beans, whole grains, broccoli, bananas, brewer's yeast and mushrooms.

Biotin is also available in supplement form, often as part of a vitamin B complex supplement , a multivitamin , or a supplement designed to improve and support healthy skin, hair, and nails

Are you getting enough biotin?

Since biotin is found in a variety of foods, deficiencies in this vitamin are quite rare. However, bodybuilders often like to eat too much raw egg whites, which can lead to a deficiency because a protein in egg whites called avidin inhibits the absorption of biotin.

Cooking destroys the biotin-binding ability of avidin, so eating cooked egg whites does not cause the same problem.

Pregnant and breastfeeding women may also find it more challenging to get enough biotin – in fact, research shows that at least one-third of pregnant women suffer from a borderline biotin deficiency, even if they are getting enough of the vitamin from their diet of.

Symptoms of biotin deficiency include brittle nails, hair loss, pale skin, muscle pain, weakness, and fatigue.

小朋友叫唔應?可能唔係無禮貌,而係科學:專注時真係聽唔到你

小朋友一睇YouTube、打機、畫畫,突然叫佢,佢完全聽唔到。係咪扮聾?係咪發展遲緩?抑或專注力問題? 研究顯示,大部分情況完全正常,與腦部的「選擇性注意力(Selective Attention)」同「過度專注(Hyperfocus)」有關,不代表有疾病。 什麼是「選擇性注意力」?(Sele...

為何肺癌早期大多沒有症狀?科學原理、風險因素與早期發現方法全解析

肺癌一直是全球最常見、死亡率最高的癌症之一。令人憂心的是,大部分肺癌患者在早期(第一、二期)都沒有明顯症狀,往往直到腫瘤擴散、壓迫周邊結構或影響呼吸功能後才被發現。本文以科學角度深入講解:為何肺癌早期「靜悄悄」、身體不察覺?身體內部究竟發生了甚麼? 亦會加入實際的自我檢查策略與醫學建議。 一...
