Black spots growing in the capsules
I like the composition of products and packaging and idea behind adapt naturals. I am glad I checked them out. I haven’t yet to see any results, because it is hard to gauge the results of taking supplements on a day to day basis especially when I take 10 other products as well? Guess I feel the same, haven’t noticed any noticeable performance degrade or upgrade, but I guess I am going to keep the course. I mean don’t get me wrong the supplements are very expensive especially also since the serving size for most products in the core bundle are more than a single pill per each day. It all adds up pretty fast so have to figure out how it’s sustainable to keep doing this month over month.
I also like that the supplements come in zip lock bags made from sustainable bags, and one can buy glass bottles for a price but yeah it make it even more expensive to do that
First time in my life that I have purchased supplements and actually felt a difference. I highly recommend adapt naturals. My only complaint is that the vitamin d does not come in glass bottles and that the packaging for the colostrum suck
Hi Paul, We are pleased to know our Core Plus Bundle is working well for you. We apologize about the packaging of the colostrum + and the D3/k2. We will definate take you concern into consider and make improvements where necessary. Thank you for leaving us a review. Best of health!
I've always found Chris Kresser and the Adapt Naturals team to be the kind of people who are on a mission to help us, and can be trusted in the exceptional quality they put out.
Hi Caroline , Thank you for trusting us with your health. We hope you are noticing the great benefits of each of the products in our Core Plus Bundle. Thank you for your support!
Best supplements I’ve ever had! My only 2 complaints are that I wish the calcium was in the multivitamin and it would be nice to just take it once a day not twice unless your that deficient
Hi Deedee, Thank you for reviewing our core plus bundle. We understand your concern, However, It does not contain calcium, iodine, and iron because Chris believes these nutrients should be individually doses (and most forms of calcium supplements are problematic when taken long term. We hope this information helps. All the best on your supplement journey!
