Meta description: Discover how IV therapy delivers nutrients for maximum absorption. Learn about the benefits, what to expect and which formulations might be best for you.
IV drip therapy has quickly moved from the hospital ward to wellness clinics and practices the world over. But as with anything that gains cultural momentum quickly, the claims can sometimes outrun the evidence, so here’s a deeper look at the science behind the marketing.
You might well wonder why IV therapy has come to high prevalence in the first place, with so many supplements widely available online and on the high street, you might question whether there’s actually a need for it. For many people, it’s not that oral supplements don’t work but their effectiveness can be constrained by the digestive process, particularly for those who have pre-existing health conditions.
When you take a supplement orally, it has to pass through the digestive system before it reaches your bloodstream. How much of it gets actually gets there (the ‘bioavailability’) depends on the compound, the dose and the health of the individual taking it. Vitamin C is good example to demonstrate this. At low doses, oral bioavailability is relatively high, but because the gut self-limits absorption as the dose increases, the body excretes what it can’t process rather than putting it to use. This is why high-dose Vitamin C supplementation orally has a cap that IV delivery doesn’t share.
Intravenous administration completely bypasses the digestive process, meaning the compound enters the bloodstream directly with 100% bioavailability. For clients with compromised absorption due to coeliac disease, IBS or chronic conditions that affect nutrient uptake this can offer a marked difference.
Contrary to what you might think, IV therapy isn’t a one-off treatment or a quick-fix solution. It’s a category of treatments with formulations that can differ quite considerably depending on what’s being addressed. Getting to know about the main components and what the evidence for them looks like is worth your time before committing to anything further.
Vitamin C
This is probably the most widely used component for its role in immune function, collagen synthesis and antioxidant activity is well established.
B-complex vitamins
B vitamins and particularly B12 are involved in energy metabolism, neurological function and red blood cell production. B12 deficiency can be common in people following plant-based diets, on long term medications like metformin or whose gut absorption is impaired. Deficiency can show up as fatigue, cognitive fog and mood changes, and it can be a long time until these changes are flagged on a standard blood panel from your GP.
Magnesium
Involved in over 300 enzymatic processes in the body, including muscle and nerve function, blood sugar regulation, sleep quality and cardiovascular health, it is also one of the nutrients found to be sub-optimal in otherwise healthy adults. Processed food diets and chronic stress are also contributors to this.
Glutathione
This is the body’s primary antioxidant, produced in the liver and involved in cellular repair and detoxification. Oral glutathione has limited bioavailability as it breaks down in the digestive tract before reaching systemic circulation in the body in large enough quantities. IV delivery is one of the few routes that reliably raises plasma glutathione levels which is why it has attracted clinical interest.
NAD+
Nicotinamide adenine dinucleotide plays a central role in cellular energy production and DNA repair. There is a growing evidence base around NAD+ IV therapy and its application in addressing fatigue, cognitive function and cellular ageing.
This is where a lot of IV therapy content goes wrong. The tendency is often to position it as something that’s universally beneficial, a wellness upgrade to anyone with the inclination and budget. The reality around which is more nuanced.
The strongest evidence base sits around people with confirmed nutritional deficiencies, compromised gut absorption, immune system challenges or those with identifiable contributing factors like post-surgical contexts. In these situations, IV therapy is a targeted clinical treatment with measurable outcomes.
For people without such deficiencies, the rationale shifts to optimisation. That means supporting function at a higher level to reduce things like inflammatory load or addressing the gap between diet and particular lifestyle demands.
What’s important here is whether treatment is preceded by testing. Blood testing is the only way to gather the baseline data to determine what is really needed over what’s generally plausible. Correcting a confirmed deficiency is a different clinical proposition from optimising function in someone whose levels are already adequate, and your treatment provider should be clear with you about this.
This leads us into a wider frustration that has become familiar to many of our clients and that is how the appetite for joined-up, evidence-based healthcare isn’t being met by adequate access to services.
It’s no secret that social media and podcast culture has made people curious about topics that would have seemed out of place a decade ago. People now want to know more about their gut microbiome, hormonal health and nutrient depletion, the issue is where to go to get that assessment.
We know the NHS is under pressure for essential services and that is something that is unlikely to change or resolve quickly. For those who aren’t presenting with acute symptoms, it can be difficult to know where to go next to get assessment for non-urgent blood testing and nutritional screening. The wellness industry is largely unregulated, which means the quality of services on offer can vary drastically and the burden of knowing the difference falls on the client.
It’s one of the fundamental reasons why we built YOR Wellness to specifically address that gap. As a CQC-regulated and clinician-led practice, we’re able to offer that joined-up care that people have researched but can’t access – blood testing, results review, tailored IV formulations, skin health and dental care all under one roof and rooted in the belief that your overall health is interconnected, not a series of separate problems.
Given that the quality of provision varies, it’s worth knowing what you should expect.
That includes knowing what baseline testing will be carried out, who your review and subsequent treatment will be with, and whether the formulations will be personalised.
There should also be monitoring throughout the infusion and a clear protocol for any adverse reactions. If you’re at all unsure, it’s worth asking the following questions:
Any provider working to the right standard will always welcome these questions and tell you everything you need to know.
Our wellness programmes begins with a thorough assessment complete with private blood testing and review. If you’d like to know more about our tailored wellness treatments, book a free consultation.
