As a growing number of scientific studies find questionable long-term side effects from common household products, many of us are left wondering what is safe to use and what we should avoid.

Fortunately, there are several health apps available to determine if there are harmful ingredients in a product, and can help you choose to switch to safer alternatives. Let's take a look at how they can help you make a positive change in your life.

1. 1Source

The 1Source app is a must for anyone wanting to take charge of their health and avoid exposure to harmful ingredients.

You can navigate through a plethora of baby, personal care, beauty, pet care, and household products with ease. It allows you to scan barcodes or ingredient labels easily to get a comprehensive profile of products including key ingredients and vital nutritional information, and whether or not they contain substances known to cause health problems.

You can save products in lists and track their expiration dates within the app. It also lets you create a personal health profile in which you can input information about your diet and health. You will then receive alerts for potentially harmful substances that are specific to your health conditions.

2. EWG's Healthy Living

With 120,000 products and counting, this free app from the nonprofit Environmental Working Group (EWG) helps you understand your food, personal care, and other household products better.

You can scan a barcode or search product names to quickly identify and analyze ingredients and see their overall rating, with 1.0 being the best and 10.0 being the worst in terms of risk and toxicity.

The Food Score rating is a powerful nutrition tool that enables you to view the nutritional value of foods and avoid those that are unhealthy. It is based on three elements: nutrition, ingredient concerns, and the degree of processing.

The app rates over 5,000 ingredients and 1,500 brands. Attributes such as calories, servings per container, protein, sugar, and fat are then displayed clearly for each product.

In addition, the app has an easy-to-use interface and provides research-based shopper guides and other useful resources to help you eat healthier and make smarter choices for your family.

3. CodeCheck

CodeCheck makes it easier to visualize vital nutrition information in a simple and intuitive manner. You can scan barcodes or EAN numbers, or enter products manually to get a full reading of the ingredients and determine whether they are vegan, vegetarian, or gluten-free.

Based on the nutritional traffic light system, this app makes it easier to make balanced food choices by highlighting healthier foods compared to others within the same category. It will show you where nutrition experts place products in terms of safety: red (not recommended), yellow (limit consumption), or green (no concern identified), based on scientific evidence.

If you want to make sure that your food choices always correspond with your eating habits, you can personalize the evaluation of ingredients within the profile section. In this way, you can receive a color-coded rating circle tailored to your dietary needs.
