The Importance of Supplements: Why Quality and Potency Make All the Difference
We live in an age when more people than ever are taking nutritional supplements. Yet despite the shelves of products on offer — from budget supermarket multivitamins to premium health shop capsules — many people report that they feel no real benefit. Their energy remains low, their immunity weak, their health stagnant. Why?
The answer, more often than not, comes down to one thing: quality.
At Planet Wellness, we have spent over 50 years guiding clients across the UK towards better health through natural means. Time and again, we have seen that the right supplements, taken at therapeutic potency, can be truly transformative. And equally, we have seen how poor-quality supplements — however aggressively marketed — deliver little more than expensive urine.
This blog explains why supplements matter, why quality is everything, and why, after decades of experience, we confidently recommend USANA Health Sciences as the gold standard in nutritional supplementation.
Watch: Which Supplements Should You Take Daily?
Why We Need Supplements in the First Place
The idea that a balanced diet provides everything the body needs is, unfortunately, increasingly out of step with reality. There are several reasons why most of us — regardless of how carefully we eat — are likely to be nutritionally deficient.
Soil depletion — Intensive modern farming has dramatically reduced the mineral content of our soil. Studies show that fruit and vegetables grown today contain significantly less calcium, magnesium, iron, zinc, and other essential nutrients than the same foods did 50 years ago. You would need to eat far more produce to obtain the same nutritional value as your grandparents did.
Food processing — The majority of food consumed in the UK is processed to some degree. Processing strips out vitamins, minerals, and beneficial compounds. Even cooking reduces nutrient content. The modern diet, for all its variety, is often nutritionally hollow.
Increased physiological demand — Chronic stress, environmental toxins, pollution, alcohol, medications, and sedentary lifestyles all increase the body’s demand for micronutrients whilst simultaneously impairing absorption. Our bodies are working harder than ever with fewer raw materials to draw on.
Poor absorption — Many people have compromised digestive systems — leaky gut, low stomach acid, poor enzyme production — which further reduces their ability to extract nutrients from even the best food.
The result is widespread, low-grade nutritional insufficiency that manifests as fatigue, brain fog, poor immunity, hormonal disruption, skin problems, and a general inability to feel well. This is precisely where targeted, high-quality supplementation can make a profound difference.

The Problem with Most Supplements
Walk into any health shop or supermarket and you will find hundreds of supplement products. But here is the uncomfortable truth: the majority of them do not work. Not because supplementation doesn’t work — it does — but because most products fall short in critical areas.
Potency — Many supplements contain nutrients at levels too low to have any meaningful physiological effect. Regulatory minimums are set to prevent deficiency, not to support genuine therapeutic benefit.
Bioavailability — Nutrients come in different forms, and the form determines whether the body can actually absorb and use them. Cheap supplements often use inferior, poorly absorbed forms of vitamins and minerals that pass through the body largely unused.
Fillers and binders — Budget supplements frequently contain unnecessary additives, artificial colours, and binders that can reduce absorption or cause reactions in sensitive individuals.
No independent verification — Without third-party testing, there is no guarantee that what is printed on the label is actually in the bottle. Some products have been found to contain significantly less — or more — of their claimed ingredients.
This is why independent, scientific evaluation of supplement quality is so important — and why the NutriSearch Comparative Guide to Nutritional Supplements has become one of the most trusted references in the natural health world.
The NutriSearch Comparative Guide: The Independent Gold Standard
Authored by nutritional researcher Lyle MacWilliam, the NutriSearch Comparative Guide to Nutritional Supplements evaluates over 1,500 nutritional products from hundreds of manufacturers using 18 critical health support criteria. These include nutrient completeness, bioavailability, antioxidant support, immune support, bone health, cardiovascular support, and manufacturing quality. It is the most comprehensive independent review of its kind.
Products are scored objectively and awarded a star rating from one to five. Only a tiny number of products achieve the coveted 5-Star Platinum Plus rating — the highest possible distinction. This rating is not bought or sponsored. It is earned solely on the evidence.
USANA Health Sciences has consistently achieved this Platinum Plus rating, making it one of the most trusted and highly regarded supplement brands in the world. USANA has also received the NutriSearch Gold Medal of Achievement — the ultimate recognition — for multiple consecutive editions.

Why We Recommend USANA at Planet Wellness
After over 50 years of clinical experience working with clients using iridology, nutrition, and kinesiology, we have tried and tested many supplement brands. USANA stands apart for a number of compelling reasons.
Pharmaceutical-grade manufacturing — USANA’s supplements are manufactured to pharmaceutical Good Manufacturing Practice (GMP) standards. This means the same rigorous quality controls that apply to medicines are applied to every USANA product. What is on the label is in the bottle — guaranteed.
Potency guarantee — Every USANA product carries a potency guarantee. You can be confident that you are receiving the stated dose of each nutrient at a level that supports real, measurable health benefit.
Superior bioavailability — USANA uses high-quality, well-absorbed forms of nutrients throughout its range. Nutrients are not only present — they are delivered in forms the body can actually use.
Cellular nutrition philosophy — USANA’s approach is grounded in the science of cellular health. By nourishing the body at a cellular level — providing the full spectrum of vitamins, minerals, antioxidants, and phytonutrients that cells require — USANA supports the body’s own capacity to maintain and repair itself.
Independent validation — The Platinum Plus rating and Gold Medal of Achievement from the NutriSearch Comparative Guide are not marketing claims. They are the outcome of rigorous, independent scientific analysis.
We personally use USANA supplements ourselves, and we recommend them with complete confidence to every client whose iris analysis and health assessment indicates a need for nutritional support — which, in our experience, is the vast majority of people seeking to improve their health.

- Noticeably improved energy levels and reduced fatigue
