Who's suppliments are you using, and are they doing the job right?
Have you considered weather what your ingesting is helping or harming you? Are you getting the nutrition you think you are? Many of the supplements on the market just pass through the body, or worse yet. They crystalize in the digestive tract where they can cause harm.
Food alone does not provide the minerals and vitamins necessary for recovery. Make sure you get the highest quality products to take care of the machine that is your body.
Without being a trained certified nutritionist myself I consider selling or recommending them to anyone else to be outside my scope of practice.
I really don't use supplements nor do I recommend them to my clients. As Ariadne said, it's out of the scope of practice for Trainers. Besides, there are too many horror stories out there about people suffering terrible side effects from using supplements - it's simply not worth it. Most supplements aren't supported by any credible research anyway. I've been relying on good old sensible nutrition & it's been working just fine for my clients and me for years.
But to answer your question, the only supplements I ever used were protein powders (bodybuilding days in the '80's!), & a multi-vitamin - that's really about it. But my question to you is - Why did you answer your own question on this thread?
I don't use supplements either, rather, relying on a balanced diet from natural whole foods. If someone insists on using supplements, I suggest they speak with a registered dietitian.
