Supplements? Legit or money-sucking?

unless your doctor advises taking a supplement (my husband takes potassium), it's totally a waste of money.

Long post sorry.
This is my personal experience with certain supplements and appetite suppressants. I have used a few different ones from a few different companies. I really love a lot of stuff made by Katalyst Nutraceuticals. Their products are sold at Nutri Shops. I love their Joint supplements, their woman vitamin mix called "For Her". I love their Glutamine recovery mix called Glutacor. I also really loved their appetite suppressant Adicor. I really did not care for their supplement called Hypercor which I think was an appetite suppressant/thermogenic.
The joint supplement is really balanced with glucosamine/chondroitin, and vitamins and minerals, and also contains tumeric to help with inflammation. It has helped my fiance with his lower back, and he can feel a big difference when he takes them every day for a while, and when he stops. They are expensive but really are worth the money.
The glutacor helps for when you get into doing hard, body stressing workouts. It has a little bit of a salty taste, is vanilla flavored and you can mix it into shakes, or take it as a quick shot in an ounce of milk.
I noticed a huge difference in my skin when I was taking the "For Her" supplements. You really have to take them for a few months before your skin really shows. I was looking at pictures of myself, and the pics I have from when I was taking the supplements religiously vs after I stopped for several months are crazy. So I am getting back into it. Also my nails are getting flimsy again.
The appetite suppressants I used here and there. The adicor I only started with one a day in the mornings. They really did help suppress my appetite. I think they were useful in learning how to portion control what I was eating. They helped me from bingeing also in the evenings. They curbed my appetite just enough so that I could eat, but not over eat. I think they may have been discontinued though. I can't seem to find them anywhere, otherwise I would buy them again. I think the main thing in them that worked was the caffeine.
The hypercor I feel no difference at all on. But maybe that is just me.
I also love Nature's way supplements. I notice a difference in energy taking them. It is probably all the b vitamins in them. I also take a daily hyaluronic acid liquid formula. It helps with skin too.

nutraceuticals!! have heard it all now.
$$$$$$$$ schluuuurppppppppppp.

Supplements and all these weight loss shakes are just Marketing 101. That's it.

Coming from someone who used to take every supplement under the sun, I can tell you first hand, they made NO difference at all. I'm talking about test boosters, fat burners, pre-workouts, etc.

I currently just take the basics- vitamins, creatine and aminos. My wallet thanks me at the end of the day.
