Listen in because what you know helps ensure healthy choices you can live with. Today on Healthy Talk, you wanted to know:I'm trying to explain to my friend that some of the research against the use of supplements is biased and not always conducted in a fair method. Can you help me educate her on the consistent flaws on anti-supplement research?Dr. Mike wants you to be sure you're getting the right information when you're looking into supplements (or any health news). It's unfortunate, but not all headlines and news sources are honest and true. When it comes to researching supplements (or any other kind of health study), you need to be sure you're looking at the right information, and doing your own research. You always want to ask yourself who is doing the study? What are the researchers studying? How are they conducting the study?Are nutrient testings reliable?Well, yes and no. The idea of being able to test your body through blood, urine, and hair sounds like a great way to find levels of vitamins and nutrient deficiencies.However, there are limitations. Let's say you have a nutrient test that's looking at magnesium levels. Whether the doctor collects that data through your blood or urine, they are only looking at the sample in a particular moment in time. At that time, your magnesium levels may appear to be low, but does that mean that they are always low?If there's a way doctors can look at your magnesium levels when you're stressed, fatigued, or feeling normal, it would give a better understanding of your levels over time.Nutrient testing is great, but you must understand the tests limitations.How much Benadryl is an overdose that can kill?Benadryl is often used to fight allergies, but lately there are well documented cases of people accidentally overdosing. High levels of Benadryl can cause confusion, sleepiness, sedation, and thickening of bronchial secretions.When taking Benadryl, you must read the label and follow instructions carefully. The amount of Benadryl you can take depends on your weight and age.If you have a health question or concern, Dr. Mike encourages you to write him at askdrmikesmith@radiomd.com so he can provide you with support and helpful advice.
