When it comes to your health, there's such a thing as taking too many supplements. Credit: Olga Shumytskaya / Getty Images
Supplements are the vitamins, minerals, herbs, and other substances meant to support, or supplement, a balanced diet. While they can offer several benefits, there is such a thing as taking too much or too many, which can lead to several serious health problems. In fact, dietary supplement complications may cause 23,000 emergency room visits in the U.S. each year, according to some estimates.
1. Drug Interactions
Taking high doses of certain supplements may alter how your body absorbs prescription medications. Use caution with supplements if you are currently taking any prescription medications for the following health conditions, for example:
Heart disease: Vitamin K reduces the effectiveness of blood thinners, such as Coumadin (warfarin). This can raise your risk of blood clotting, which may lead to a heart attack or stroke.
Cancer: Vitamins C and E may interact with certain cancer treatments. Avoid taking any additional supplements without discussing them with your cancer care team.
Depression: Taking St. John’s wort can affect how your body processes antidepressant medication or other drugs, making them less effective in treating your symptoms. When combined with antidepressants, St. John's wort can also increase your risk of serotonin syndrome, a potentially deadly condition when you have too much serotonin in your body.
2. Vitamin Toxicity
Vitamin toxicity can occur when excessive amounts of a vitamin build up in your body. This can happen when you take large or frequent doses of vitamins or supplements. Signs of vitamin toxicity of common vitamins and minerals may include:
Some supplements may cause uncomfortable digestive symptoms, such as nausea, vomiting, diarrhea, or cramping. Taking high doses of the following supplements may upset your stomach:
Folic acid
Iron
Magnesium
Vitamin C
Zinc
4. Kidney Damage
Some medications and supplements may damage your kidneys. This pair of organs is responsible for filtering and excreting drugs from your body. Taking too many supplements or very high doses of certain supplements, including licorice root and St. John's wort, may cause damage. This is especially true if you already have kidney disease. A 2016 study also found that taking too much vitamin C may increase the risk of kidney stones in some people.
Next Steps
Many adults can take their daily supplements safely and without serious health complications. To ensure that your supplement plan is safe, consider the following steps:
Talk with your healthcare providers: Give your doctor or pharmacist a complete list of your medications, vitamins, and supplements. They can help you understand your risk of any potential interactions. Doing so is especially important before surgery or any medical procedures.
Follow the dosage recommendations: Do not exceed the recommended dosage for any of your medications, vitamins, or supplements.
Monitor for side effects: If you experience any unwanted health changes after starting a new supplement, stop taking it and talk with your doctor.
Use caution during pregnancy: If you're pregnant or breastfeeding, it's important not to take any supplements other than a prenatal vitamin without discussing them with your doctor first.
Selenium is an open source tool that made a sensation when this arrived in the business sector. It’s a free software with all the great features and was therefore able to quickly gain market share where QTP was a figurehead. Selenium provides various functions and is premised on larger-scale java scripting.

Why selenium?
Selenium facilitates testers to write the code to write the script in one operating system and to run the same test scripts on multiple browser platforms. WebDriver is now becoming part of the W3C standard for all browsers, thus designing browsers that will obviously support Selenium.
The important feature of this test automation tool is that it enables testers to test user experience modules, provides a wide variety of test options, results were compared and finally verifies whether or not they are consistent with the expected application behavior. Selenium’s “SENDKEYS” method equates test scripts written in different languages into Selenium in an accurate manner.
Selenium is considered as an important tool because of its attractive benefits such as transparency, platform independence, fosters continuous integration efforts, reduces the turnaround time and can be easily integrated with other automation tools as well.

What is UFT?
It is one of most major trading players on the market. It primarily uses VB Scripting as its scripting language. It’s very simple to use and packed with advanced features. It uses the Object Repository to identify and capture objects. It can be easily integrated with many other automation tools, such as the Quality Center, and can update the results.
Why UFT?
UFT One/QTP is a Micro Focus automated testing testing tool that uses computerized analysis to assess glitches in a test application.UFT One is mainly used only for functional testing, regression and service testing. Using UFT One, you can optimize user behavior on a web-based or client-based software program and test and recognize bugs on the same actions for different users, different data sets, different Windows operating systems and/or different browsers.
UFT One is among the most popular commercial automation testing tools available in the market today. It is recognized for its simplicity of use and assistance by the vendor and a huge automation tester community. Due to this reason, qualified UFT One experts have always been in demand.
Brief History of Selenium
Jason Huggins developed Selenium in 2004 in Chicago. He was working at Thoughtworks as an Engineer on web app testing. Using JavaScript, Jason developed a program for testing. After using it, he realized the faults in manual testing. He named it JavaScriptTestRunner initially, but after that, he renamed it Selenium core and made it open source.
But still, there were some issues with using it. If someone uses JavaScript with a different domain name, it is forbidden to do so. For this, testers must install the Selenium Core and Web Servers, including web app testing that belongs to the same domain. Thus, another Engineer from ThoughtWorks, Paul Hammant, developed a Selenium Remote Control (RC) solution. Later, two other components, Selenium Grid and Selenium IDE, were created by two other professionals in 2006.
Further, in 2008 the core team of Selenium automation testing combined Selenium RC and Web Driver and brought Selenium 2. After many years changes & improvements took place in it, and it paved the way to release Selenium 3.
Later, after a few years, Selenium became an open-source tool and has become a more powerful tool in the market. Many companies use Selenium for web automation testing of various apps. It makes web testing easier and faster.
Career Aspects
Many organizations, especially those which are service-based, use Selenium which is now a popular open-source tool. Many companies use it for web and application testing. It is highly adaptable due to its flexibility to integrate with major programming languages. Further, there is good growth for Selenium in the future, and there are many job opportunities in this field. It is easy to learn and practice for everyone interested in web automation testing.
Brief History of UFT
Mercury Interactive initially developed UFT in 1998, and its first version was Astra QuickTest. But later, in 2006, it was acquired by HP, and it became HP QTP. Later, in 2011, HP combined the two tools, “HP Service Test” and “HP QuickTest Professional,” and released a new device with the name “HP UFT 11.5” (Unified Functional Testing). Then, in 2016 was completely sold to another company Micro Focus which is managing and supporting UFT.
Career Aspects
UFT is a more powerful and useful tool in comparison to Selenium. Due to its huge license cost, many business entities still need to be ready to adopt this tool for automation. Moreover, UFT integrates with many tools, mostly paid tools. They are reducing their demand in the market. For beginners in Automation, UFT is not the right fit to learn as there are only a few job opportunities for freshers. Further, it offers a free trial of 60 days, after which you need to buy the tool for further usage. It is a major drawback here. Also, there needs to be more information available on UFT, which makes it difficult to learn in-depth.

Application Type:
UFT: It supports web, mobile, API, hybrid, RPA, and enterprise apps.
Selenium:Selenium will only be used for web-based applications. It is a big downside of selenium over QTP.
Application Languages:
UFT: UFT could be used to test the functionality, the service layer and the database layer for all three layers of the application.
Selenium:Selenium is only used to test the front end or the interface layer.
Supported Languages and Browsers:
UFT: It supports visual basic script language and chrome, firefox, safari and IE browsers.
Selenium: It supports java, python, ruby, perl PHP, javascript languages, and safari, firefox, chrome,IE, opera , headless browsers, etc.
UFT: Supports microsoft windows and comes with builtin UFT IDE
Selenium: Supports microsoft windows, apple OS X and linux, and comes with eclipse, intellij and other IDe that are supported by Java.
Supported technology:
UFT: Supports almost every significant software application and environment, such as SAP, Oracle, Salesforce, mainframes, embedded frameworks, headless browsers, and more.
Selenium: Selenium is struggling while automating SAP, Salesforce, mainframes applications.
Required coding skills:
UFT:You needed less programming knowledge as it provides keyword-driven testing that streamlines test creation and maintenance. Acquisition flows from the application screens and utilize UFT’s robust recording/replay capture technology.
Selenium:You need to have a good knowledge of programming language. For each Selenium binding, you need to know the programming language.
Test execution performance:
UFT:It needs more system resources. It can operate on Windows VM that uses more resources and needs more maintenance.
Selenium: Selenium requires less system resources and can be used in Windows or Linux VM applications. Linux VM is lightweight compared to Windows VM.
Tools integration:
UFT: Can be integrated with limited tools and mostly that are paid tools only
Selenium: Can be integrated with paid tools very easily.
Test reports:
UFT: Test reports are generated by default.
Selenium: For test reports these are needs to be integrated with other tools
Career Growth:
UFT: UFT offers less jobs, limited scope for expansion
Selenium: Selenium comes with more scope, more jobs in future as well.
Cost
UFT: HP UFT is a license-based testing tool that offers a trial period of 60 days to its new users. But after that, you need to buy the license, which costs much higher.
Selenium: Selenium has a good market share compared to HP UFT, an open-source tool. Many enterprises prefer to use it to manipulate the Selenium architecture as needed. Also, they can expect much better performance while conducting tests.
So we’ve seen so many discrepancies between UFT and Selenium. The main key driver is the automation cost. If you’ve a budget plan and you can manage QTP, it’s best because it has various characteristics. If your project has a lower budget, go to Selenium, but you need to make more effort.
Selenium is limited to the web page. If your test cases need to communicate with your desktop, such as uploading files, download files a file and checking, etc., Selenium may not function reliably in those instances, while UFT can easily streamline those contexts. Integrating Selenium with Test Management Tools is no easier than UFT. Selenium needs to be integrated with various reporting tools and managing.Selenium needs to be incorporated with various tools for reporting and managing data that are accessible in UFT by default. UFT scripts are going to be more stable than Selenium. UFT is rich in performance available to Selenium.
With the help of disitivcitve feature of UFT it can easily reduce the amount resources need in writing the scripts whereas selenium requires more resources to write lines of code.But you’re going to get less help available on UFT’s public online forums, but it has proper support as it’s a paid tool.
