I bought 4KG of protein isolate from this company not long ago and I must say, their customer service was shocking. They gave me a tracking number that turned out to be non-existent. When I tried to get help by emailing their customer service, I got no response at all. The lack of communication and inability to give correct tracking details left me feeling really annoyed and let down. I'd advise anyone thinking of buying from them to do some research first.
Great tasting protein
A major problem I had with other protein products I have tried is their taste. It often feels like torture taking some of them. I bumped into reviews of Optimum Nutrition protein products and got attracted when I read that their products had a great taste. I decided to give them a try with an order of French Vanilla and Milk Chocolate. The product arrived within 1 week after my order. I was also very impressed with the taste of their protein products and have since stuck to them. I was also lucky to get a discount of 15 per cent when I made my order.
About Optimum Nutrition
Every athlete understands the importance of a proper diet in their training. An improper diet not only reduces and sometimes defeats the efforts made in training, but it could also put the athlete at risk of health complications. Therefore, all athletes not only regulate what they eat, but they also take supplements to make up for whatever nutrients they might lack. And when it comes to energy, nothing provides more than a good protein supplement. Optimum Nutrition asserts that they have what athletes need for their protein requirements. However, most athletes are very conscious of what they put into their bodies and may be wary of trying any new product. Therefore, reading honest customer reviews of Optimum Nutrition from individuals who have tried the protein supplements the company offers would be prudent.
