In many of our products, our Vitamin A is in the form of beta-carotene. Beta-carotene is converted by the body to Vitamin A, which is shown to be an antioxidant, to protect the skin and eyes, and to provide nutritive support for a healthy immune system. Beta carotene is a carotenoid found in plants, responsible for the bright yellow and orange hues in many fruits and vegetables (famously in carrots!). These pigments play an important role in plant health. People who eat foods containing carotenoids get protective health benefits as well.
There are many studies that found beta-carotene to have cancer-preventative effects, providing important antioxidants to ward off disease and lower inflammation. For non-smokers, beta-carotene has been shown to improve respiratory health. And, while study results have been mixed over the years, many have found that an inverse relationship between carotenoid intake, including beta-carotene, and lung cancer risk. For as many studies you find indicating one, though, there are those that indicate the opposite. The different literature also notes that none of these results suggest that beta-carotene supplements cause lung cancer, but they do indicate that they don't help to prevent it where smoking is a risk factor.
As with all health and wellness supplements, we recommend that you speak with your physician or healthcare professional to determine if our vitamin is suitable for you to take, particularly with this concern. Medically and legally we cannot advise you on whether the liquid vitamin is safe for you to take, as there are many variables that go into determining that fact. Your personal physician or healthcare professional knows you best and can advise you what is best for you.
