Brain Octane Power!

I run multiple businesses, so I need every advantage I can get. Adding Brain Octane to my Bulletproof coffee each morning gives me the mental clarity, focus, and sustained energy I rely on throughout the day. It also keeps me satisfied, making it easier to stick to OMAD (One Meal A Day) without distractions.

BIOptimizers Stress Guardian
Alison (Sydney, AU)
Stress Guardian

I’ve recently purchased this product and it seems gentle on the stomach and I think I am starting to notice a little more calm in my day. I need to take it for a few months to really see the benefits but so far so good!

Excellent product Magnesium Break through

I am very impressed with the company and the quality of their products
It’s the only magnesium I can find that contains so many of the different types our bodies need

Best Coffee Ever

The original is still the best :-) I love Bulletproof coffee and don’t drink anything else. This is the best one especially if you are making a real Bulletproof coffee with butter & brain octane.

Great product and service

Amazing for my bullet coffees

Troscriptions Just Blue
Stephie (Melbourne, AU)
Fast delivery effective product

Order was processed and delivered in under a week. Really been enjoying the just blue troches.

Great support

No aftertaste, easy to swallow and clean ingredients. Perfect for an omega boost. Will definitely buy again.

Early days using the Cognibiotics product,however, so far have experienced greater clarity.

As with the BIOptimizers range of products (Masszymes, Herbal Power Flush, ParaGuardian,) etc. results are always excellent.

Highly recommended.

Cymbiotika Probiotic

Only thing I found which removes foot fungus. .

I used have previously use the Cymbiotika Product with great success.
I have been attending a public pool facility and need to use it again to stop the foot fungus.

Smooth and steady

TLDR: this coffee has a smooth flavour, doesn’t leave me with the jitters or irritate my bladder.
I’m one of these people whose brain doesn’t really switch on with a coffee but I never got around the bitter taste and always would get the jitters. I actually didn’t notice until switching to bulletproof coffee that other coffees were probably irritating my bladder or something, because those times that I forget to reorder before I run out and use the other coffees in the house I definitely notice now how much they have me needing to relieve myself often. And this coffee doesn’t leave me with the jitters like other coffee does.

Good quality product

Good quality product. It was recommended by my Mums doctor. It seems to work

Best Menopausal Cure

Before taking these I was having bad night sweats, broken sleep, headaches and bad constipation. I was taking a magnesium tablet, however when I saw something online in regards to this one, I was so desperate and thought I would try. Initially I bought once, a little skeptical and noticed, I was feeling better. The bottle finished and when I went to order it was sold out - all my symptoms came back - while I waited for it to restock. I now always order 3 bottles, so I never run out - it has been life changing for me- I tell all my friends that are going through this period- as I have found this product amazing!!! I will tell anyone that will listen. Truly recommend - and I am not the type to normally right reviews - good or bad, however this one really deserves it.

Magnesium Breakthrough

I love this magnesium product. I find I sleep better, my muscles recover quicker, and my bowels work more effectively. Have tried many magnesiums but this one wins over all!

What a difference!

Out of nowhere I started developing severe restless legs and after a friend recommended your product to me, I started taking the Magnesium Breakthrough capsules. After only a few days, I started feeling a difference and my RLS has improved significantly. I still occasionally get it (after having too much caffeine) but it is only mild and does not keep me awake at night. This product is a game changer!

Magnesium Breakthrough

Magnesium Breakthrough is a very good product. I get it because I have sleep problems and I find it helps me considerably with that. Your service is excellent, my order is always delivered promptly. Thank you

Awesome website

My experience has been fantastic with this website. They sell great products and delivery is super speedy.

Sulfuraphane for Bladder Cancer

My Sister has Bladder Cancer and she has been taking Sulfuraphane for a couple of months now, she has not yet had her scheduled checkup, but we are hoping that it will have worked helping to stop her tumors growing. We got to know of this from a friend Dr Alan Bruce who has been taking sulfuraphane for his pancreatic cancer, and as far as I know he is going really well.

Bulletproof™ MCT Oil - 946 ml
Mandy Costello (Melbourne, AU)
Bulletproof Mct Oil - 946 ml

Love this product. I require a high quality, pure MCT Oil for medical reasons, and my research brought me to the Bulletproof MCT oil, which is not only providing me with necessary fats (triglycerides) but has also improved my energy levels, and cognitive function. Not only that, it is very palatable, having no flavour. I highly recommend this product.

MCT C8

This stuff really works my wife has advanced dementia and use this with a keto diet and her basics have iproved amazingly
She now eats unaided and we used to have to hand feed her
She can now also pick up a coffee cup and we used to use a baby sippy cup. She is walking better and has less anxiety and she had eczema her whole life and it has cleared up in just a few months quite amazing. Would give 10 stars if I could
I also did this as it was easier for both of us and I’ve lost 12 kg and my vision seems to be improving so there’s really something in it
Steve.
