Hello, friends! I have a few questions (vitamin experts wanted, also)! Forgive the novel.

Hi friends,

How are you all doing today? It is Saturday here... first time I have seen the sun and sky for a while (been overcast for the past few weeks). When I start typing, I can end up writing a novel, so please bear with me (or just hit the hard shut down button on your computer now and grab a cup of Java)! For those of you that are pressed for time or your flight attendant is telling you to stow away your electronic devices, you can go to my bullet point questions down below.

I want to give a little background on me, and I must embarrass myself. Ever since I was a young one, I have had a bad diet, and I mean bad. Very rich in fast food, and lots of it. It troubles me to think about it. I used to go to Sonic and order three burgers. I got on the Atkin's diet, and I was successful (I lost a good bit of weight), and then someone caused me to cave. I was very strong on the diet, but it was my diet partner, and you know - once you try one sweet thing, you are off of it! I blame it on myself entirely. So, I go to my doctor's, and I am 20 years old [by the way], and she tells me you are quite young to have hypertension. I knew I was eating bad, but any time I get stressed in college or anything, I will eat. So, let me not write much more than that except to say 5 days ago I have started, again, using MFP and I am adamant this time. I am not eating fast food, except I have been eating Chick Fil A grilled chicken sandwiches and maybe an occasional cobb salad (I am learning they are high in sodium).

• So, here is where we get to the questioning. I recently bought some Garcinia Cambogia Supreme. I was skeptical, but I must say I am feeling a little bit of results from it (but I have heard skeptic things and that is not 100% safe, so I may throw it away). Anyone have any factual review or anything on it? I think I may have gained a pound using it.
• I am looking for a great vitamin to cover all of my nutrients and help with blood pressure (but one that is safe and FDA approved). I am a large grown man, so it would have to be a men's one (that may go without saying)! I notice when I go on a diet, I get headaches from lack of food (and I assume nutrients), so if there is a vitamin that helps with that, we are talking!
• MyFitnessPal gave me a 2,700 daily calorie intake. What on earth? I am 6'2" - 273 lbs, and I set it to lose 2 lbs a week. I spoke to a nutritionist who told me to lower it to either 2,400 or 2,500 which I have, and she changed my fat, protein, and carb goal. Not sure if that is too high of a goal or what.
• I have high blood pressure, so is there any additional medicine I can take for that, such as a vitamin that is safe? I realize this is not a vitamins forum, but Google has sent me every which way - I think I ended up on a website advocating vitamins, and then it was part of the deep web.

That is all I have for now, and I intend to start exercising soon. My nutritionist is preparing me a workout plan. I want to get down to 195 lbs.

I really appreciate you taking your time to read this. I look forward to beginning this journey with all of you.
