The question that freezes everyone
Arms folded. A little smile. Then the question you have probably heard more than once: “Sure, but does that stuff actually get into you, or does it just pass straight through?”
If you have ever gone a bit vague at that moment, you are grand. It is the one thing that stalls a good conversation dead. So let us answer it properly, because do fruit and vegetable supplements work is a completely fair question, and there is real research that lets you give a straight answer.
No hype. No dodging. Just what the science actually found, and one honest line you can have ready.
And honestly? The person asking is no fool. They are right to want to know their money buys something real. So the worst move is to bluff your way through it. The best move is to know the answer cold and say it plainly.
Do fruit and vegetable supplements work? Here is what a blood test showed
In 2017, researchers writing in the journal Nutrients did something simple and clever. They gave healthy adults the capsules made from concentrated juice powder of 36 different fruits, vegetables and berries. Then they took blood samples over the next ten hours to see what actually turned up.
And things turned up. The plant compounds, the polyphenols, appeared in the bloodstream. Some arrived early, within an hour or two. Others showed later, five to ten hours in, as the body worked its way through them.
Picture tracking a delivery landing in stages across the day. First parcel by mid-morning, another by teatime. The point is the parcels arrived. Researchers watched the good stuff from the plants show up in the blood, hour by hour.
There was a neat detail in it too. The early arrivals came straight through the gut in the first hour or two. The later ones showed up because your own gut bacteria kept breaking the plants down for hours afterwards, releasing more as they went. Your body was working the whole day, not just the first sip.
More of the good stuff, in your blood
A second study backs that up. Back in 2003, work published in the Journal of Nutrition found that people taking a fruit and veg concentrate had higher blood levels of antioxidant vitamins and folate. In plain English, more of the good stuff from fruit and veg ended up in their bloodstream.
Two studies, one honest headline you can stand behind. The compounds are absorbed. They show up where you would want them to.
The honest caveat that makes you MORE trustworthy
Here is the part that actually earns you the conversation. Say it out loud, every single time.
The capsules do not replace real food. Whole fruit and veg bring fibre and water that a capsule never will, and that matters. The concentrate is there for the busy days, the days your plate falls short of the veg you meant to eat. And most of our plates fall short. We went through that gap already in getting enough fruit and vegetables, where the honest truth is almost nobody hits their veg on a normal week.
When you tell a customer that plainly, something shifts. You sound like someone worth trusting, because you handed them the honest limit before they even had to ask for it. The person who says “it tops up your veg on a busy day, and it will never do the job of a real dinner” is the person people believe.
How to answer without sounding like an advert
So the next time it comes up, you have a real answer ready, in your own words.
Try something like this: “Yes, it absorbs. There is a study where they took blood samples and the plant compounds turned up in the bloodstream over the hours after. It is a handy way to top up your fruit and veg on the busy days.”
Then add the honest bit, because it earns you trust: whole food still matters most, fibre and all. The concentrate is there for the days the veg falls short. Say that part plainly and watch how people relax.
Keep it light on the promises too. Give them the finding and the honest limit, then let them weigh it up like an adult. That bit of restraint is the thing that makes a yes land further down the line, when it is their own decision and not your pitch.
Most of the time this question lands in a DM or a comment, so keep the reply warm and human the way you would any other chat. If you want the longer version of how to open and hold those conversations, we walked through it in how to start conversations in the DMs. And answering a hard question straight, with the research behind it, is exactly what authentic content looks like. Honest, specific, calm.
Educate first, and the rest follows
The truth is your best tool here. Say it with a bit of confidence and you are already ahead of most.
So save the honest line. Save the two study names, the 2017 Nutrients blood-sample study and the 2003 Journal of Nutrition one. The next time someone asks whether it is worth it, or whether it just passes straight through, you will have a calm, evidence-backed answer ready, and you can let them decide from there.
That is the whole game. Educate first, warmly, no pressure. The offer looks after itself once people trust you.
Send this post to anyone who asks the question, or just lift the one honest line from it. One honest read does more for you than ten pushy messages ever will.
