Outstanding Customer Service from BRAINEFFECT!

I recently placed an order with BRAINEFFECT, but unfortunately, the delivery driver from GLS lost my package.

Even before the original order was located, the BRAINEFFECT customer support team immediately sent out a replacement so I wouldn't be left without my products. Outstanding responsiveness!

When the lost package was finally found, I ended up with two orders. I reached out to customer service to ask for return instructions, and to my absolute surprise, they told me to keep the extra order as a gift.

This is a rare level of generosity and truly impeccable customer support. A huge thank you to the team for their professionalism. I highly recommend ordering from them!

No Day w/o Brain Effect

We use various Brain Effect products on a daily base e.g. Daily Gut, Mood, Sleep, Vitamin D3 and Focus if needed.

We have been using the products for a couple years now and wouldn't want to miss them. Orders are delivered within a few days.

If you want to try some of the products in advance I can recommend their yearly adventcalender, as it contains samples of the existing and new products.

Unfortunately exactly the opposite- made me sick

Bought the “Daily Gut Pro” and got super sick. Couldn’t drink or eat without running to the bathroom at least 25-30 times a day. Felt super weak, swollen belly, and just sick like you do after food poisoning. Really cannot recommend it! Its not for your gut health. I suppose its some typ of lacative!

Flat belly and no dark circles anymore

So far I've only been experiencing great effects from the products. The probiotics are working just great on my belly that's been swollen for way too long. I use to hold my breath to look better in my jeans. Now it's over, and I'm just feeling well in my body ! I also used the sleep gummies as I sweet tooth person. One day I forgot to take them and had a really tiring and uncomplete night . I realized afterwards that I haven't taken it the night before.

I am using the sleep spray on a regular…

I am using the sleep spray on a regular basis and i like it a lot. Definitely helps me to fall asleep a bit faster. Ordered it already 5 times so far. But i am removing one star, since there are other melatonin sprays out there for less money with more melatonin (so less spray pumps required).

No effect whatsoever

No effect whatsoever. Very unhappy with this product. I even tried increase the dosage but nothing. Also gave me headaches.

Felt horrible after taking it

Warning ! I bought Brain effect focus to try to improve my concentration. I wish i had read all the negative reviews online first. I felt horrible after just 1 day of taking the capsules. Stomach pain, and a vicious headache that went away as soon as I stopped taking them. My brother tried them a week later as well and was also immediately sick like me. Waste of money and possibly dangerous. How is this stuff legal?

Very bad with terrible side effects

My daughter took a single Brain effect capsule in order to help her study for her exams. She followed all the directions but sadly experienced all the same side-effects everybody else has been reporting, after just 20 to 30 minutes of taking the capsule she felt nauseous and couldn’t stop trembling. When we contacted brain effect through their German website for advice we never got a response. The side-effects are well reported and after my daughters experience we would suggest finding an alternative. If I can give it no stars I would and the one star rating feels generous. I hope this helps. Marta Barcelona Spain

Brain Effect Focus is a SCAM! - A complete waste of money

SCAM ! Overpriced, over hyped German rip off . Brain Effect Focus did nothing for me (if anything my concentration seemed to get worse) and when my boyfriend tried them for a week it made him sick with vicious stomach cramps. Contacted the company by email, never had a reply. Tried to call the number to only ever get an answer machine Terrible non existent customer support and here I was thinking the Germans are meant to be efficient. AVOID

Terrible service, paid and received nothing.

I ordered from this company on the 23rd of May. It is now the 10th of June, and I have had no contact from them. I followed up via email with them on 7th June to find out what was happening with my order, and received an automatic email response with a ticket number for my query. Now three days later I still have had no reply from them. Would definitely NOT recommend. Very poor (non existent) customer service. I will have to now contact my bank to get my money back.
