Seems to be working well
Seems to be working well. I’m having more better skin days using this supplement. My only negative is the flimsy packaging. The lid cracked almost straight away when I started using them so it wouldn’t screw on tight. I had to use cello tape to put it together so I could screw the lid on tight which isn’t ideal. Other than that a quality product I think

I love their Magnesium
I love their Magnesium, I’ve been taking it at bedtime for the past few days and noticed a difference in the quality of my sleep. The little tablets are so easy to swallow. I love the beautiful packaging too, it’s sustainable and looks great on my bedside table!

RESOLVED - Zero customer service, lost order
Placed my order, money taken, order confirmed and then nothing. Tried messaging twice to find out what was happening, no response. No idea if I’m going to get my order or if I’ll need to raise a case with PayPal. Can’t recommend, avoid.
Update- Since posting the company have been in contact and resolved the issue.

Hi there,
We are unable to identify your order from this review, so we can't verify your order or assist you with it. We are so sorry if you have had a negative experience and would like to be able to try to make it right. Can you contact us with more details?
Thank you,
Simple Science
Poor service
Poor delivery service to Northern Ireland.
Odd number of capsules in a container.
Passive aggressive emails from them telling me to take my business elsewhere, after I left a less than positive review.
Questionable experience with effectiveness of their supplements.
This is after 3 or 4 orders so I've tried them multiple times and based my experience across a number of months.

Dear Carl,
I am so sorry for this experience. I wish that you had got in touch with us about your order so we had the chance to sort this out for you, as we were not aware that there was a delay until now. In order to reach your address in Northern Ireland we had to use Yodel for your order, who are not our usual fulfilment. We will be back to our normal fulfilment now, including relatively fast speeds to NI.
Still we think this slowness is unacceptable. I am going to get in touch with you via email now.
Very best,
Rachel
