Product Reviews

Based on my research and proffesional use I find this supplement to be the best on the market. As someone who fasts regularly these tablets help me to get through the day feeling focused and energised, mental clarity and performance is second to none. Taking these with the electrolyte formula is the only way to start my day. Definitely feel the benefits however the price is slightly up there for the supply, it can become quite costly.

I have been taking C8 MCT Oil for going on two years now, adding it to my Bulletproof coffee in the morning. I've noticed an increase in my sharpness as I start the day & feel an energy burst also. My concentration levels have also improved. Because it's tasteless the coffee is pleasant to drink. Highly recommended.

Love this product. Switched from Cymbiotika and feel the results are equal plus in a super easy capsule form!

Simple to mix, versatile and taste good when combined with greens, coffee etc

I was nicely surprised after I took akkermansia, my GI symptoms disappeared. If I don’t take it, the symptoms return again within 48 hours. It definitely works!!

So far so good

I’ve been struggling with waking up in the middle of the night and tossing and turning for hours. Since starting to take the magnesium capsules only a few days ago, I have been able to reduce my wake up time in the night. I’m really pleased

these supplements have helped me so much on top of a balanced diet. They really are magic and highly recommend.

Useful dose/capsule means you can take one, two or three capsules daily depending on what you’re trying to achieve. Excellent option for vegans. No downsides to this product as far as I’ve been able to tell. Going to test my Omega-3 levels in the next few weeks, and that’ll be the final test to make sure it’s working!

Impressed on how quick delivery was, easy to order, competitive pricing, will definitely order again.

So far after only a week taking these tablets x3 twice daily has helped me sleep better. Next time may choose the powdered version. Thank you a happy satisfied customer Helen 😊

Trusted site with high quality products and lots of information.

Since adding Perfect Amino to my nutrition regime I have effortlessly gained muscle and bone mass! I couldn’t be happier.

Fast delivery, Well packaged, Awesome products as expected. The glasses don’t let any blue light in.. 15mins after wearing them and I get sleepy.. sleeping much better. The C8 is superb as always and as expected!!

The Mentalist Bulletproof coffee is my favourite coffee along with French Kick. It comes perfectly ground for an Aeropress and always tastes divine. Highly recommended.

Been using Bullet Proof Coffee for years but this was my first try of the Mentalist. Love it! 💯💪❤️

I’ve used it for 7 years and find it excellent for my coffee. Together they curb my appetite so I extend my overnight fast by a few hours.

Very happy with this Essentials Kit, giving me the tools to begin my own Bulletproof journey. Delivery was prompt with follow-ups by OptimOz. Looking forward to results across a few levels. Thx

Improved muscle recovery time and much better sleep.

My PERFECT AMINO supplement always arrives on time and have been packaged well. It would be more convenient if the tablet strength could be increased so you don’t have to take 5 in one dose.The Amino capsules are a great supplement to take and convenient for travelling due to their size, unlike bulky powdered shakes. Thank you OptimOZ for your support and service….

I have only used P3-OM for a week. I can clearly feel much less bloated after my dinners.

Seems to work pretty well.

Love this stuff - shared with a friend who has had major gut isues and she noticed a difference very quickly. Gentle but effective is what I like! Now we both purchase it. Bloody brilliant!!

My first time using this product and I heeded the suggestion to have a small dosage initially. I definitely feel the difference in my clarity of thought and energy levels.

Great product! Noticed a difference immediately. Sleep is great and now I take it daily.
