Juice Cleanse and Supplements UK: What to Take, When, and Why

If you've done a juice cleanse, you know the feeling on day two. Clear head. Less bloat. The noise that surrounds eating three meals a day suddenly gone. It's real and the reason it works is that a well-designed cleanse gives your digestive system a genuine rest while flooding your body with micronutrients it's probably been short on.

We built Presscription Juices do for exactly this reason. We made sure everything is cold-pressed on the day of delivery, 80/20 veg to fruit so the sugar stays low. It's built around the same philosophy we built Guudies around no shortcuts, ingredients chosen for what they actually do.

But here's the question we get asked a lot: should you take supplements during a juice cleanse? And what should you be taking the other 361 days of the year when you're not cleansing?

Do Supplements Interfere With a Juice Cleanse?

The short answer is no and for most people, continuing your supplement routine during a cleanse is worth doing. The long answer depends on what you're taking.

Fat-soluble vitamins (A, D, E, K) absorb better when taken with food containing some fat. Cold-pressed juices are almost entirely fat-free, which means if fat-soluble vitamins are your primary concern, timing matters take them with the one meal or nut milk in your cleanse programme rather than with a straight green juice.

Water-soluble vitamins and minerals B vitamins, Vitamin C, zinc, iodine are unaffected by the presence or absence of fat and absorb fine alongside juice. If anything, taking your B12 and Vitamin D during a cleanse is more important, not less, because your food-derived nutrient intake is temporarily reduced.

Functional supplements like adaptogens, mushroom extracts, and ACV work well alongside cleansing. Reishi and Lion's Mane don't interfere with digestion and the cortisol-lowering effect of adaptogens can actually support the cleanse experience for people who feel anxious or headachey in the first 24 hours.

What Nutritional Gaps Does a Juice Cleanse Leave?

Even a brilliantly formulated juice cleanse and Presscription's are will be low in a few things by design:

Protein. Juice cleanses are not a protein source. This is fine short-term but worth knowing if you're training during a cleanse.

Fat-soluble vitamins at full absorption. As above D, E, K absorb less efficiently without dietary fat. Take them with the nut milk component if your cleanse includes one.

B12. Cold-pressed juice contains no B12. For vegans especially, maintaining B12 supplementation during a cleanse is non-negotiable.

Iodine. Unless your cleanse includes significant amounts of sea vegetables, iodine is likely low. UK adults are already chronically low in iodine as dairy consumption falls a cleanse temporarily removes one of the main dietary sources.

What to Take Alongside a Juice Cleanse

Keep it simple. You don't need to add complexity to what's meant to be a reset.

A well-formulated daily multivitamin covering B12, D3 with K2, iodine, and zinc keeps the nutritional foundations covered without adding anything that interferes with the cleanse process. Our DailyGreens does exactly this full multivitamin profile, 200mg greens blend of 14 superfoods, two vegan gummies. Easy to take alongside your morning juice.

If gut support is one of your cleanse goals reducing bloating, resetting digestion our ACV gummy pairs well. Apple cider vinegar with the mother supports stomach acidity and protein breakdown. It's one of the mechanisms Presscription's own ACV-containing juices use, in gummy form for the other days of the year.

What to Do After the Cleanse Ends

This is where most people lose the benefit. The cleanse resets your system. What you do in the 72 hours after determines whether that reset holds or reverts.

The standard advice reintroduce food slowly, start with vegetables and soups before reintroducing grains and protein is correct. What's less commonly said is that the cleanse period is an ideal time to establish a supplement habit, because the routine is already disrupted and you're already paying attention to what you're putting in your body.

Attach your daily supplements to your morning juice. Whether that's a Presscription delivery day or an ordinary Tuesday with a homemade green juice, the anchor is the same. The habit that forms during and immediately after a cleanse tends to stick because the motivation is at its highest point.

The Bigger Picture: Cleanses and Supplements as Complementary, Not Competing

The supplement industry and the juice industry rarely talk to each other. They compete for the same health-conscious consumer rather than acknowledging that they're solving different problems.

A juice cleanse is an acute reset three to five days of concentrated micronutrient intake, digestive rest, and a break from the noise of normal eating. Supplements are a chronic foundation the daily nutritional insurance that covers the gaps that even a good diet leaves over weeks and months. Neither replaces the other. Both do something the other can't.

The people who get the most out of both are the ones who treat a cleanse as a quarterly or biannual reset and daily supplements as the non-negotiable baseline in between. It's a more expensive approach than doing neither. It's also significantly more effective than doing either in isolation.
