Natural Stacks Avis 

I did not have any effect from one of their magnesium combo supplements for sleep so I left a review for the product. They deleted it. I’ve tried to leave a review after they delete it but word each review different so it’s not about “authenticity”. They delete each one claiming it’s “authenticity”. If they are doing it to me they are doing it to all bad reviews skewing their ratings. Would not trust this overpriced fake company.

Does not give you any energy as stated. Stayed with it for 3 weeks hoping it just needed time to get in my system. Don’t waste your money

I had purchased the Dopamine Brain Food, and I was super excited to try these and could not wait until they had arrived, but if I can give my honest opinion, it doesn’t do anything it says that it’s supposed to do. I gave it a few tries just to see if I could feel what the people on the add were saying that they felt, but it just wasn’t there. I never want to make anyone or company, feel bad or anything I just like to give my honest opinion. The delivery came in a good timely manner.

Happy Customer, awesome supplement! Long time customer of the Dopamine Brain Food. absolutely lives up to its claims. As a Gen Xer over 50, I’m selective about supplements, and this one stands out Focus is sharper & mental clarity is noticeably better!

I cancelled my subscription and they shipped it and charged me for it anyway. Be careful when buying from the company directly! I should have paid an extra $1.00 and bought it through Amazon again. The company has internal communication issues to the Point of ripping you of your money. I will never buy anything from Natural Stacks again.

UPS is missing information needed to clear the shipment. They initiated contact with the sender. But this company says that customs regulations are outside of our control. Lost my $170.

Their Sleep Magnesium Gummies kept me up all night. I had tried several times to give it a chance but up all night was the effect. Their Dream CBD was a much better product but is discontinued. Also bought Zen Magnesium Gummies and MagTech® Magnesium - Single Bottle - 90ct but am afraid to take any of them. Tried to request for a return authorization but was refused because it was past their 30 days return policy. The stuffs are going in the garbage where they belong and wasted my money. Would never buy any of their products again. False advertisement!!!

To be honest these guys are total legit... their products rocks and their support is spot on... best thing to do is leave a message and they will call you back and they do back their products... as for those who had bad experiences not sure what to say but they fixed the issue really fast!!

These formulas are awesome, I cant get through a proper workday without taking their NeuroFuel and Dopamine together. Love it, I have never taken supplements to help my focus and drive but this is a game changer. Website is easy to navigate and the company is always running promos and deals.

Bought an item that was to be sent to Denmark, Natural Stack made a mistake in the Commercial invoice and I had to pay both customs and tax.

When you write to them, you are just ignored.

Thanks for poor customer service, lost money and a lot of hassle.

Stupid company, absolutely fraud

Item not delivered. Company is not taking responsibility. $200 down the drain.

I'm a full time Nootropics researcher and I've always been impressed with Natural Stacks' rigorous commitment to creating high-quality products
