Unfortunately, for sake of a good answer, this could be so many different things. I'll try to highlight/mention as many as I can. To start, my best advice would talking with a good MD and ask about blood testing. That being said when the results come back I would recommend asking lots of questions and even consider having multiple MD's look at the results ...

There can be a number of issues at work here, and to really understand what's going on, you'll need to talk to your doctor. It's not normal to always be fatigued in the way you are describing. There are a number of things you need to be asking yourself: Am I sleeping enough? Insufficient sleep causes a multitude of problems including fatigue. NOTE: hours ...

Do you have any reason what so ever to assume you have a vitamin c deficiency (also known as scurvy) ? If not, don't waste your money, even if they're cheap. Supplement companies make loads of money on peoples ignorance and morally speaking, these companies should be starved until they go bankrupt. It's incredibly easy to get all the vitamin c you need, if ...

There are some studies that link low vitamin D levels with various issues, such as "winter depressions", but it should be remembered that this does NOT mean that vitamin D supplements will make you less depressed or give you more energy.

To give a somewhat related example (but not perfect) of bio-...

This question, as worded, is off-topic. But, since I've written such a program in the past, I'll point you to what I used. The USDA maintains a Nurtient Database that can be downloaded. If memory serves me, it's large and is distributed in several parts. There is documentation to help you decipher each part of the download.

This probably ought to go without saying, but prioritize doctor advice over nostrums offered by coaches, friends, random internet people, etc. There's a lot of confusion out there between "needs supplementation because deficient in this specific nutrient" and "MOAR SUPPLEMENTS! AND GREEN TEA!" Most people are getting sufficient nutrients in their diet and, ...

The Truth People tend to go overboard with the POWER of vitamins. You're likely getting what you need from food already, but taking a multi-vitamin won't hurt. Fat Soluble Vitamins A, D, E, K are stored in the liver and the only vitamins you can "overdose" in a healthy adult this is faily rare. Why? They can build up in your system as they don't dissolve ...
