人类会有意识地从吃的食物中获取他们所需要的维生素和矿物质。然而，糟糕的饮食和食品加工技术，可能会导致维生素的损耗，从而影响你的健康。一些维生素补充剂已被发现含有大量有助优化健康和确保你得到需要的所有营养物质。由于对维生素D在心血管健康和血糖调节方面的重要性进行了较多研究，所以其在心血管健康方面的重要性日益受到重视。一些证据表明，低水平的维生素D参与了许多疾病，包括肥胖、癌症和老年痴呆症。如果你想优化你的健康，确保获得足够的维生素D是一个明智的决定。维生素B12对于人体细胞中的血管和神经的正常功能至关重要。许多因素可能会导致饮食中的维生素B12量不足或者吸收不良。缺乏维生素B12会导致贫血，严重疲劳，呼吸困难，食欲较差及认知功能丧失。如果你是一个素食主义者，你可能就得不到足够的维生素B12，个人的消化条件可能无法正常吸收营养。不是很多人都熟悉抗氧化的叶黄素，是对眼睛健康的一个重要营养素。这是一类胡萝卜素化合物,，与维生素a和β-胡萝卜素有关。已经有研究表明，叶黄素有助于降低白内障和黄斑变性的风险－－与衰老相关的眼部疾病。一些研究人员也将它与降低患心脏病和中风的风险联系起来。叶黄素一般由绿叶菜、绿色蔬菜、鸡蛋、豌豆和布鲁塞尔豆芽等提供。叶黄素经常包含在对眼睛健康的维生素补充剂中。健康专家们已经知道钙对强壮骨骼和牙齿的重要性，有人声称它对防止骨质变薄的骨质疏松症的发生起着关键性的保护作用。钙也有不足之处，可能与心血管疾病、肥胖、高血压等有联系。一些研究人员声称，许多成年人并不将可能提供足够钙的牛奶或酸奶作为他们的日常饮食，在这些情况下，一个包含钙的补充剂有助于预防疾病。

服用维生素补充剂，以上4种将确保你为维持良好的健康和预防许多疾病而需要得到的足够营养。

4 Vitamin Supplements That Will Boost Your Health

Humans are designed to get the vitamins and minerals they need from the foods they eat. However, poor diets and food processing techniques can lead to vitamin depletion that can impact your health. Several vitamin supplements have been found by many to be helpful in optimizing health and ensuring that you are getting all the nutrients you need:

Vitamin D

Vitamin D is getting new scrutiny as its importance in cardiovascular health and blood glucose regulation has undergone more research. Some evidence indicates low levels of vitamin D are involved in a number of diseases, including obesity, cancer and dementia. If you want to optimize your health, making sure to get plenty of Vitamin D is a wise decision.

Vitamin B-12

Vitamin B-12 is critical for normal function of blood and nerve cells in the body. A number of factors may cause insufficient amounts of vitamin B-12 in the diet or poor absorption of vitamin B-12. A deficiency of vitamin B-12 can cause anemia, severe fatigue, breathing problems, loss of appetite and poor cognitive function. If you eat a vegan diet, you may not be getting enough vitamin B-12. Individuals who have digestive conditions may not be able to absorb the nutrient properly.

Lutein

Not many people are familiar with the antioxidant lutein, an important nutrient for eye health. It is a carotenoid compound, related to vitamin A and beta-carotene. There have been studies done that indicate lutein is helpful in reducing the risk for cataracts and macular degeneration – eye diseases that are associated with aging. It has also been linked by some researchers to lower risk for heart disease and stroke. Lutein is provided by consumption of leafy, green vegetables, eggs, garden peas and Brussels sprouts. Lutein is often included in vitamin supplements for eye health.

Calcium

Health experts have known calcium is important for strong bones and teeth for many years, some claim that it is also critical in preventing the bone thinning that occurs with osteoporosis. Deficiencies of this important mineral have also been linked by some to cardiovascular disease, obesity, high blood pressure. Some researchers have claimed that many adults don’t consume the milk or yogurt that could provide sufficient calcium for their daily diets. In these cases, a supplement that contains calcium may be helpful in preventing many of these disease conditions.

Taking a vitamin supplement that contains these 4 items will ensure that you are getting an adequate amount of the nutrients you need to sustain good health and prevent many diseases.
