This depends on the type of fast and your goal. Most people actually practice time-restricted eating rather than true fasting. Any food restriction under 24 hours is time-restricted eating. The benefits of fasting beyond 24 to 72 hours come from autophagy, and the products will break this process. Beyond 72 hours this effect is reduced and it is advisable to take the products to support the detoxification process. Under 24 hours you can take the products as normal.

Jeff’s Ultimate 4 and Boost have been game changers for my husband and I. We’ve been on them both for a month and our energy levels have gone through the roof! I’ve been dancing through the day like a little kid. No need for caffeine anymore 🙏😊
Only been using Ultimate 4 for 10 days now and I do feel like I have more energy. The test strips started off almost white but happy to say they are now registering slightly pink which means it’s working Woo Hoo 🙌
I knew Jeff designed good products because years ago I relied on 30 plus for women, so when I saw he had nitric oxide, I had to try it. I’ve been using it for two weeks and I certainly have more energy and sleep better, the arthritis in my knee has changed. I will keep using it
I am amazed at how quickly my energy increased. I have been having B12 shots every 3mths for years with no real benefit.
Ultimate 4 helped after only a few days and it tastes great.
Taste great , levels increased within a week & could definitely feel the increase in energy , almost too much energy after 2 weeks on it, so I reduced my dose to every 3rd day
Have been on the products now for about 5 months have lost about 8 Kilos and feeling so much better, i still have a journey but my confidence is returning!!
The boost 3 is so much better than the multivitamins i used to take and much better quality.
Boost 2 is also effective .
Can’t rate Jeff enough when Australia Post stuffed up my order. That’s how customer service should be.
My name is Sheryl Ogston I am 75 years old, my daughter Rochelle gave me the ultimate 4 and boost 3 for my birthday, I have been talking it for a month now. I am feeling great, more energy, brain fog better, just feeling better all round and my nitric oxide levels are up to 110mg/L. I have been telling everyone I know to get onto it. Thanks Jeff for such great products.
So far one tub and energy more consistent. Took overseas whilst conquering the streets of Japan! Definitely needed! Purchased my second tub and will test more with this one to check NO levels
I noticed a difference in my energy levels & the flow on effect was my mood, within days of starting this. I can’t wait to see the long term effects it has.
2nd tub just started and enjoying the taste and easy of mixing the drink of a morning.
Starting to feel my energy increasing. Sleeping better and not needing to hit the snooze button on my alarm 😄
Following Jeff's recommendations with diet and exercise and looking forward to feeling fantastic again
Whilst it is too early to show an increase in my nitric oxide readings as I’ve only been taking this product for a few weeks, I definitely have more energy and improved brain function.
My journey started in February this year, 2026.
I felt unwell all over. The worst of it was a headache at the back of my head that just would not shift. I was tired, feeling dreadful, training hard and somehow getting fatter and sicker at the same time. My blood tests were all heading in the wrong direction — cholesterol up, non-alcoholic fatty liver not going anywhere. All the classic signs of metabolic disease.
The frustrating part is that I was doing the right things. I've dabbled in alternative health for years, I've tried plenty of different supplements and vitamins over that time with varied results, and I've got a great GP who's right into the alternative side. But I still felt like I was going backwards.
I started on the lot — Boost, Prostate Plus, Mens Plus and Ultimate 4. For the first two months I actually felt worse, with a weird sore throat that hung around. I mentioned it to my GP and told him what I was taking, and he said it sounded like detox. I emailed Jeff and he came back with the same thing. So I stayed with the program.
Sure enough, the sore throat went. Then the headaches went with it.
I'm now at least six months in and I feel so much better. Better all over. I've also been following Jeff's advice alongside the products, and to date I've lost a good 12 kilos of stubborn fat.
Having looked into this stuff for years, I recognised the ingredients in Jeff's formulas straight away. They're the best of the best of what I already knew about, all in the one place. Considering the quality, I reckon they're good value.
I've still got a journey ahead of me, but I feel far more positive about my overall health than I did in February. As a 57 year old bloke, I can't recommend Butterworth Health enough.
I was taking the women’s bundle for a month. Felt the benefits almost immediately. Unfortunately due to postage, my recent order got lost. I didn’t have anything for 3 weeks. Extremely disappointed, but I just had to be patient. My order finally arrived a few days ago and hands down, the best feeling! I actually think in hindsight the few weeks without these amazing products actually proved to me how good they really are. I Feel AMAZING! Thank you Jeff…. Long may this last🙏🏻
Loving this supplement. Can truly say this has had a noticeable effect with energy levels and overall feelings of wellness. So happy with this purchase. Thank you
I have only been taking it for two weeks but have seen a slight improvement in the testing stick level - in relation to energy I am yet to feel any difference but understand it may take a bit longer than two weeks to feel an increase
I have been taking these products for 4weeks now, and they taste delicious, however, I have not as yet, physically noticed any differences/benefits - but my levels are getting better each week when I test.
