The only difference is post workout I take combat power instead of 100 whey. No, this isn't a weight gainer. It is a time released protein meaning it has fast-slow digesting proteins to keep you more anabolic throughout the day. It has 2.5 grams of fat and 4 or so grams of carbs. Combat Powder is a decent protein and it is fine to take post-workout. Since it is a blend though, you could use it pretty much anytime of the day, including before bed. 100% whey is a isolate/concentrate protein so it's probably more ideal post-workout.
The main purpose of iron is to help in the transportation and storage of oxygen to all parts of the body. In addition, iron assists in energy production and cell respiration, while also helping the immune and central nervous systems. Men should generally take 8 to 10 milligrams of iron per day for optimal health.
The amount of iron prescribed by your doctor will be in milligrams (mg) of elemental iron. Most people with iron deficiency need 150-200 mg per day of elemental iron (2 to 5 mg of iron per kilogram of body weight per day). Ask your doctor how many milligrams of iron you should be taking per day. If you take vitamins, bring them to your doctor's visit to be sure. There is no evidence that any one type of iron salt, liquid, or pill is better than the others, and the amount of elemental iron varies with different preparations.
