What are the benefits of vitamin B3 to health?

维生素B3对健康有什么好处?

1. Vitamin B3 helps to lower LDL cholesterol

维生素B3有助于降低低密度脂蛋白胆固醇

Vitamin B3 has been used since the 1950s to treat high cholesterol. In fact, it can lower LDL bad cholesterol levels by 5% - 20%.

维生素B3自20世纪50年代以来就被用来治疗高胆固醇。事实上，它可以降低5% - 20%的低密度脂蛋白胆固醇水平。

However, vitamin B3 is not the main treatment for people with high cholesterol due to possible side effects.

然而，由于可能的副作用，维生素B3并不是治疗高胆固醇患者的主要药物。

Instead, it is primarily used as a cholesterol-lowering treatment for people who cannot tolerate statins.

相反，它主要用于不能耐受他汀类药物的人的降胆固醇治疗。

2. Vitamin B3 has the effect of increasing HDL cholesterol

维生素B3有提高HDL胆固醇的作用

In addition to lowering bad LDL cholesterol, vitamin B3 increases the amount of good HDL cholesterol.

除了降低有害的低密度脂蛋白胆固醇，维生素B3还能增加有益的高密度脂蛋白胆固醇的含量。

Studies show that vitamin B3 increases HDL levels by 15 - 35%.

研究表明，维生素B3能提高高密度脂蛋白15 - 35%的水平。

3. Vitamin B3 has the effect of reducing triglycerides

维生素B3具有降低甘油三酯的作用

Vitamin B3 can also lower triglycerides by 20% - 50%. Vitamin B3 blocks the action of an enzyme involved in triglyceride synthesis. Therefore, this reduces the production of both very low density LDL and lipoprotein.

维生素B3还可以降低20% - 50%的甘油三酯。维生素B3阻断了一种参与甘油三酯合成的酶的作用。因此，这会减少极低密度LDL和脂蛋白的产生。

To achieve these effects on cholesterol and triglyceride levels, you need to use the vitamin B3 dosage prescribed by your doctor.

为了达到对胆固醇和甘油三酯水平的这些效果，你需要使用医生开出的维生素B3剂量。

4. Vitamin B3 works to help prevent heart disease

维生素B3有助于预防心脏病

The effect of vitamin B3 on cholesterol may help prevent heart disease - but newer research suggests an additional mechanism that benefits your heart. It can help reduce oxidative stress and inflammation, both associated with atherosclerosis, or arteriosclerosis.

维生素B3对胆固醇的作用可能有助于预防心脏病，但最新的研究提出了一种对心脏有益的额外机制。它可以帮助减少氧化应激和炎症，两者都与动脉粥样硬化有关。

Several studies indicate that vitamin therapy - alone or in combination with statins - can help reduce the risk of health problems related to heart disease.

一些研究表明，维生素治疗——单独或与他汀类药物联合使用——可以帮助降低与心脏病相关的健康问题的风险。

A recent review concluded that niacin therapy did not significantly reduce the risk of heart attack, stroke or death from heart disease in people with heart disease or those at high risk.

最近的一项研究表明，烟酸疗法并不能显著降低心脏病患者或高危人群心脏病发作、中风或死于心脏病的风险。

5. Vitamin B3 may help treat type 1 diabetes

维生素B3可以帮助治疗1型糖尿病

Type 1 diabetes is an autoimmune disease in which your body attacks and destroys insulin-producing cells in the pancreas.

1型糖尿病是一种自身免疫性疾病，在这种疾病中，你的身体会攻击并破坏胰腺中产生胰岛素的细胞。

There is research showing that vitamin B3 can help protect those cells and may even reduce the risk of type 1 diabetes in children at risk.

有研究表明，维生素B3可以帮助保护这些细胞，甚至可能降低风险儿童患1型糖尿病的风险。

However, for people with type 2 diabetes, the role of vitamin B3 is more complicated. On the one hand, it can help lower the high cholesterol levels often seen in people with type 2 diabetes. On the other hand, it has the ability to raise blood sugar.

然而，对于2型糖尿病患者，维生素B3的作用更为复杂。一方面，它可以帮助降低经常出现在2型糖尿病患者身上的高胆固醇水平。另一方面，它也会提高血糖。

Therefore, people with diabetes who use vitamin B3 to treat high cholesterol also need to carefully monitor blood sugar.

因此，糖尿病患者在使用维生素B3治疗高胆固醇时，也需要仔细监测血糖。

6. Vitamin B3 works to enhance brain function

维生素B3能增强大脑功能

Your brain needs vitamin B3 - part of the coenzyme NAD and NADP - to get energy and function properly.

你的大脑需要维生素B3——辅酶NAD和NADP的一部分——来获得能量和正常运作。

In fact, some brain diseases and even mental symptoms are associated with vitamin B3 deficiency.

事实上，一些脑部疾病甚至精神症状都与维生素B3缺乏有关。

Certain types of schizophrenia can be treated with vitamin B3, as it helps offset damage to brain cells that occur due to deficiency.

某些类型的精神分裂症可以用维生素B3来治疗，因为它有助于抵消由于缺乏维生素B3而对脑细胞造成的损害。

Preliminary research suggests it may also help keep the brain healthy in cases of Alzheimer's disease. However, this result still needs more research.

初步研究表明，它还可以帮助阿尔茨海默症患者保持大脑健康。然而，这一结果还需要更多的研究。
