Nicotinamide riboside (NR) is converted in the body to nicotinamide adenine dinucleotide (NAD+), which is critical for cell metabolism. A disruption in NAD+ may result in diseases, such as metabolic diseases, aging, and other degenerative disorders. Taking NR supplements may raise and disrupt NAD+ levels. Researchers have found that high levels of NR may increase the risk of triple-negative breast cancer, and also cause the cancer to metastasize to the brain.
烟醯胺核糖(NR)会在体内被转化为对细胞代谢至关重要的烟醯胺腺嘌呤二核苷酸(NAD+)。若干扰了NAD+在体内的水平会导致疾病，例如：代谢性疾病、老化和其他退化性疾病。服用NR补充剂可能会提高和干扰NAD+的水平。研究人员发现，高量的NR会增加三阴性乳癌的风险，还会导致癌症转移至大脑。

Certain Supplements Linked to Serious Health Issues
Some supplements sold in the U.S. for weight loss, muscle building, energy, and colon cleansing, have been found to lead to health issues—with about 40% categorized as severe problems, including death—for nearly 1,000 people aged 25 years and below, according to U.S. FDA records. Supplements claiming to help with weight loss, muscle building, or energy were almost 3 times more likely to cause harm, while those marketed for colon cleansing were about twice as likely to cause harm. Many of these products have been found to be tainted with prescription drugs, heavy metals, and pesticides. Choose supplements wisely.
有些补充剂与严重的健康问题有关
美国FDA的记录显示，在美国销售的某些用以减肥、生成肌肉、提供能量和清洁肠道的补充剂，被发现导致大约一千名25岁及以下人士的健康出现问题——大约40％属于严重的问题，其中包括死亡。宣称有助于减肥、生成肌肉或是提供能量的补充剂，有大约三倍的可能性会对身体造成伤害；而那些标榜能够清洁肠道的补充剂，有大约两倍的可能性会造成伤害。这类产品许多都被发现含有处方药，或是受到重金属和农药的污染。消费者需谨慎明智地选择补充剂。

Many people take vitamins, but they do so without full knowledge of the consequences. Vitamins aren’t necessarily good for you, and it’s far too easy to overdose on them. Too much vitamin C and D may cause: kidney stones, difficulty in controlling blood sugar levels, heart issues, blood clots, red blood cell destruction, dangerous abnormal heart rhythms, poor appetite, nausea, vomiting, and constipation.
许多人服用维生素补充剂，但他们没有完全了解后果。维生素补充剂对您不一定是好的，而且太容易就会服用过量。过量的维生素C和D可能会导致：肾结石、难以控制的血糖值、心脏问题、血栓、红细胞被破坏、危险的心律异常、食欲不振、噁心、呕吐和便秘。

It is important to remember that a multivitamin cannot in any way replace a healthful well-balanced diet. The main purpose of a multivitamin is to fill in nutritional gaps, and provides only a hint of the vast array of healthful nutrients and chemicals naturally found in food. It cannot offer fiber or the flavor and enjoyment of foods so key to an optimal diet.
