I have been supplementing my protein intake with your Whey Smooth protein powder for quite some time and it’s absolutely delicious! However, I am concerned about the amount of cholesterol per scoop in the Whey Smooth - 75mg. Can you please help me understand if this is going to make my cholesterol go up or what do you suggest I do? My cholesterol is border line and I eat rather clean. Wondering if this could be culprit. Thoughts? Thank you!

The Weight Loss and Liver Support supplement - does it really matter if it’s 30 minutes before a meal? For example, I usually have a meal replacement shake for breakfast that contains my coffee for the day. I usually take my Weight Loss and Liver Support supplement, then go to the gym - cardio for about 15-20 minutes and then work out on machines/ body weight. It’s usually 45 minutes to 1 hour before I actually eat. Does it make a difference if it’s 30 minutes or is it okay that it’s more than 30 minutes before an actual meal?

I came across a video just the other day, where Arnold Schwarzenegger was explaining the benefits of using Cherry Tart Concentrate to assist in muscle/joint pain, muscle recovery, and improved sleep. The product claims these results are due to the high levels of antioxidants, including anthocyanins and melatonin. I was somewhat skeptical, because you can never be too sure when seeing celebrities promoting different products. I did some research of my own online, and I ended up with mixed reviews. Some articles/reviews swear this product helps, however, others claim it to be just another fad. I was wondering if you could share some professional advice on this product.

Supplements

I see that your product VeganAminoXXXL is labeled vegan, but I am very curious what the source of the amino acids come from. My question for you then is what is the source of the microbes you are fermenting? I know majority of companies are using corn or soy. I'm hoping to get full transparency on this product before I give it a shot.

I’ve been wracking my brain to help my one of my clients lose weight but little to no success... She is 40, 230 lbs, 42%bf, has tried so many different fad diets over the years with some success in the past and always puts it back on, several hiit style boot camps/classes. She has a slow metabolism and a sedentary job. I’m stuck. I’ve researched so many avenues.

Coaching

Would dotFIT ever consider producing a powdered electrolyte supplement? I thought that if you ran with the idea, you could incorporate the superior science and formulation that has earned dotFIT such respect: something like vitamin water meets Gatorade, with purposeful micronutrients added to aid in recovery. Alternatively, could we just add some electrolytes to a version of AminoXXXL for the best of both worlds? Do you think there would be a market for a product like this?
