The tablets have a new coating, and most of them were all cracked and split open. Not busing these anymore, total crap!

This is a great product and I love ON as a company and I have been using their Gold Standard Protein and this product for over 5 years. The only reason i gave it a 7 is like what several other buyers have said, the products that I receive arent always consistent. With the most recent purchase, the pills were beige instead of the usual yellowish color and the color varies from pill to pill which to me is discoloration of some sort. I am not sure who's fault it is, whether it's the manufacturer's issues or the way Bodybuilding.com handle the shipments. When I contacted customer service, they almost make me feel like it was my problem that the pills look the way it did even when I offered to have the product ship back as part of the exchange. Didnt like that a bit.

Have been using these multi vitamins for over 3 years now consistently. during that time I have had 2 batches once being my most recent purchase, where they basically fall apart outside of the bottle. I use a vitamin carrier and after 3 days, they split open. Not only do they not go down smoothly, they do not taste that good. The product is a great product, however, the consistency of quality is fair at best.

This used to be a great product. I have recently had 2 bottles of the larger quantity come and they stink like something foul. The last bottle I bought smelt bad, and it gave me the s#@ts. I am giving them one last chance and if I get another bottle like this I am going to file a lawsuit on someone’s ***!

It's nice and all that the pills have all these different ingredients in them, however after some research it appears vitamins with a USP certification are the best route to go as it ensures the pills fully dissolve in your stomach for maximum absorption. I contacted ON customer service to inquire about it and I can pretty much assume that these pills have no such certification. Their customer service never answered the question despite a series of back and forth exchanges and the bottles have no such marking. Point is that you can claim high potency or whatever you want but it doesn't mean it is if you're not certified. Without getting into details I do want to say that I've encountered a few situations in the bathroom that make me question their potency. At the end of the day it's your money and it's your choice, but I won't be buying these again despite being a long time user of their protein powders.

This is one of my favorite go to vitamins when I need a more dense nutrition supplement added to my daily meal intake. I definitely recommend you to give this a try. Especially if you want the best fuel going into your system.

I never use this product, I am using some protein powder and multivitamins. I want to know that if is use this product so should i still need to take some protein or this tablet is enough, Is there any side effect i always be careful to take anything because i am Thyroid patient. Please let me know if there any suggestions. Thank you!

Great blend of nutrients. Yes the powdering is a problem but its not due to the vitamin its due to the fact that plastics (like polyethylene pill boxes) are porous. They let in air and moisture and hold particles after they're washed. Put some spaghetti sauce in you pill box for a day and see what happens when you rinse it out. I changed to a small glass jar with a steel lid... problem solved.

A few of the included vitamins / minerals are not in their ideal forms, including K, zinc, and magnesium. Personally this product causes me to sometimes feel the opposite of what it's claiming, I feel fatigued and lathargic, It's also missing some key B vitamins which would have been nice, calcium and zinc also shouldn't be present in the same multi in my opinion and one should get their zinc either from diet or a ZMA at nighttime

I have been using this product for my hardcore bodybuilding regime. i know i will get some serious bodybuilding guys mocking me, but really, if you are having this 3 a day, then you don't want to waste your money on any other bodybuilding supplements. This product is good enough to give you the necessary boost in your hardcore workout regimen. Yup, you need to have a good diet tagged along with its intake. i would say, just stop all other supplementation and you will see what I am talking about. No miraculous strength, but your stamina & strength will enhance each day as you proceed. Good Luck. take Care.

I think that will be better than now if they add fish oil (Omega 3) but actually it maybe hard becouse they produce that in solo product . It makes other brand Better .
