[Music] what's up guys dr. Mike here today I'm going to talk about a subject I'm incredibly passionate about and that's vitamin there's a ton of misinformation out there from people peddling cancer cures heart disease prevention I'm going to focus on two major vitamins today they are causing a stir in this conversation vitamin D and vitamin b12 so what are vitamins what a fun it's not they make you feel better and they vitamins are things that our body needs to drive supplements your body on track sources of energy vitamins are substances that are found in everyday foods that allow your body to function properly and ultimately grow there are two types of vitamins fat soluble vitamins and water soluble vitamins the fat soluble vitamins are vitamin D E K a your water soluble vitamins are vitamin b1 b2 b3 b5 b6 b7 b9 b12 and vitamin C first let's take b12 what's b12 its cobalamin it's a supplement that a lot of doctors are recommending for things like fatigue or increased weight loss so what does the research say currently there is no evidence that supports the claim that b12 supplement improves your fatigue or helps you lose weight there are some patients who do need vitamin b12 supplementation but those patients are few and far between with only 1% of the population having a true vitamin b12 deficiency when you come to your doctor with symptoms of fatigue or weight gain vitamin supplementation should not be the first thing that's talked about your doctor should do a full physical exam of thorough history and order the appropriate lab tests to figure out what's the source of the problem before jumping right away to supplementation [Music] vitamin D is vitamin D important yes very important I don't know why it would be but I'm sure that it is different for your skin of semester so I think helps bone I'm probably happier if they put your ball we do something touted as the miracle vitamin the miracle pill I've seen some crazy headlines of people claiming it cures cancer cures depression prevents heart attack strokes but what evidence is really out there to support all of these claims currently the good quality evidence shows that an average healthy person there is no benefit to supplementing with vitamin D so why is everybody talking about vitamin D as if it's a miracle pill well there have been some smaller studies that have shown promise for vitamin D in prevention of some diseases in decrease in respiratory tract infections improvements in treating depression however dot promise has not yet been replicated in good quality large studies what evidence has shown is that people who get more sick tend to have a lower vitamin D level what's not clear is this the cause of the illness or the result of the illness it's really the story of the chicken and the egg guys if you're worried about having a vitamin D deficiency you have to remember that mild vitamin D deficiency shows no symptoms at all and severe vitamin D deficiency shows very vague symptoms like bone pain and muscle weakness what do you do if you think your vitamin D deficient well since we've seen that there's no clear evidence to supplementing vitamin D you can focus on getting vitamin D naturally through your diet tuna salmon great examples of fish that have high vitamin D content also dairy foods cereals another great way to get vitamin D to spend 30 minutes outside twice a week allowing the Sun to heat your exposed skin if after focusing on the Sun and diet you still feel like you have a vitamin D deficiency or symptoms of a vitamin D deficiency close to your doctor have that conversation and see if a vitamin D test is exactly what they recommend [Music] do you know how much vitamin D you should get in a day no 1000 1000 if you have low vitamin D how would you know how would I know if it went to the doctor and found that out is there such thing as too much vitamin D I think so yeah what happens then I feel vitamins have been touted to promote general health and to prevent chronic illnesses but that's simply untrue however there is some promise important to remember while all these people are talking about the benefits of vitamins we have to remember that there exists vitamin toxicities which means that you're getting too much of a visor especially the fat soluble vitamins that we mentioned earlier Deka can build up in your system because they're dissolved within your own body's fat tissues those who have a nutritional deficiency a vitamin deficiency most certainly should take license but odds are that's not you hope I'll be able to cut into the noise for you when it comes to vitamin I know it's a controversial subject leave your comments leave your questions and if you haven't yet hit subscribe
