I try to stick with the basics. The three must have supplements that I always take are a quality multivitamin, omega-3's or fish oils, and a quality protein powder.Everything else such as your pre powders and fat burners can help you towards your goal but they are not essential. Your body needs so many vitamins and minerals to properly function throughout the day and whatever the body does not get thru your diet it will find elsewhere. First place your body looks is your muscle. Your body will eat away at itself if the right nutrients are not provided. That is why a multivitamin is so important. A good multi is your body's insurance policy, ensuring it has everything it needs to work. Omega's 3's do it all. Numerous studies are published everyday on the benefits of omega 3's. Some benefits include healthy brain function, cardiovascular health, hormone production, muscle recovery, fat metabolization (keeps me lean), prevents arthritis, etc. I take 1g with every meal. And last but not least, a quality protein powder. Protein is essential for not only athletes but everyone. Your entire genetic makeup is made up of protiens. Protein powders are a more bioavailable form of protein than most other plant and animal sources. Also, the reason I use it is for overall convenience. It is a lot easier to down a shake than trying to eat a chicken breast every 2-3 hours. Optimal times for a fast digesting protein would be before and immediately after workouts. Whey protein digests much faster (within 30 min) than whole food animal protein. You need to start the recovery process immediately after your workout to reap the benefits of it. Now, these 3 supps are what I use everday and will continue to use. I do however use other supplements such as creatines and preworkouts but not all the time. Again, get your nutrition in check and then fill in the gaps with supplementation.
