Name: Strong not Strict Nutrition
Price range: $$

Why this matters to me. Due to previous experiences with supplements, I wanted to grow my knowledge and understanding of products, the science and how to help people make better-informed decisions.

Strong Not Strict Nutrition did not start with a logo or a slogan. It started with questions and a growing frustration with how much influencial marketing sits between people and the information they actually need.

This is the story behind the name, what “strong” and “not strict” really mean in practice, and why I take supplement quality so seriously.

Key takeaways

Evidence-led advice should be confident about what is known and transparent about what isn’t.
Flexible nutrition is not the absence of structure; it is structure that can survive real life. We need colour!
Supplements can carry quality, labelling and contamination risks(this is documented, not hypothetical).
Third-party batch testing can lower risk, but it cannot guarantee zero risk.
Food should do most of the work; supplements should have a clear purpose. Not just because I was told.

Why I wanted to learn more

Due to previous experiences with supplements, I wanted to grow my knowledge and understanding.

I began asking better questions. What do consumers assume when they read a supplement label? What controls exist in manufacturing? What steps can reduce risk and where does uncertainty remain?

Learning more helped me recognise that supplement decisions require the same evidence-led thinking as any other area of nutrition. Familiar ingredients, confident marketing and professional-looking packaging do not remove the need to examine quality, purpose, dosage and risk.

That desire to understand more became part of the reason I created Strong Not Strict Nutrition.

The problem is bigger than one product

People often treat a label as a guarantee that the contents perfectly match the front of the tub. The real world can be more complicated.

Inaccurate labelling — the amount or identity of an ingredient differs from what is declared.
Cross-contamination — substances are unintentionally transferred between products or production lines.
Adulteration — undeclared substances are added, sometimes to create a stronger effect.
Batch variation — one batch may not match another, even from the same brand.

These problems are not equal in every category. Risk tends to be greater in products marketed for rapid muscle gain, fat loss, sexual enhancement or extreme performance.

The research is worth knowing:

An international analysis of 634 “non-hormonal” supplements bought in 13 countries found that 94 (14.8%) contained anabolic-androgenic steroids that were not declared on the label (Geyer et al., 2004).
A study of melatonin supplements found content ranging from −83% to +478% of the labelled amount, with lot-to-lot variation of up to 465%. Serotonin was detected in eight of the products tested (Erland & Saxena, 2017).
A review of the US Food and Drug Administration’s tainted-supplements database identified 776 adulterated products between 2007 and 2016. In 97.6% of cases, the unapproved drug ingredients were not declared on the label (Tucker et al., 2018).

None of this means every supplement has a quality problem. It shows why a familiar ingredient name or a slick label does not remove all quality concerns; a point echoed in the International Olympic Committee’s consensus statement on supplements (Maughan et al., 2018) and a more recent review of adulteration in sport (Jagim et al., 2023).

What “Strong” means

Strong advice is not advice delivered with the loudest voice.

For me, Strong means:

Starting with the best available evidence.
Giving more weight to high-quality human research than to anecdotes or mechanisms alone.
Distinguishing a promising idea from an established result.
Explaining uncertainty rather than hiding it.
Changing my position when better evidence appears.
Refusing to sell fear, detoxes or mythical shortcuts.

Science rarely gives us perfect certainty. Evidence-led practice means making the best decision available now, showing the limits and reviewing it when the facts change.

What “Not Strict” means

I like cake. I like pizza, burgers, Haribo and chocolate.

That does not make me less serious about nutrition. It is exactly why I refuse to build plans that only work when life is unnaturally controlled.

Not Strict does not mean “anything goes”. It means:

No moral labels such as “good” and “bad” attached to individual foods.
Portions and frequency matched to the goal.
Space for social events and favourite foods.
Skills for managing trade-offs rather than endless avoidance.
Maintenance periods and diet breaks when they serve a purpose.
A plan that can be adjusted when work, family, sleep or stress changes.

A flexible plan still has structure. The difference is that the structure serves the person, instead of demanding the person serve the diet.

How supplements are governed and what that means for you

In the UK, food supplements are regulated as foods rather than medicines. Businesses are responsible for the safety, composition and labelling of what they sell, and supplements cannot legally claim to prevent, treat or cure disease (UK Government; Food Standards Agency).

Regulation does not mean every product has been independently tested for every possible contaminant before it reaches the shelf. Nor does a compliant label make a supplement necessary or effective.

That is why careful product selection matters. It is also why I start with a simple question: Is there a genuine need? Sometimes there is. For example, the NHS advises that everyone in the UK should consider a daily 10 microgram vitamin D supplement during autumn and winter, when sunlight is not strong enough for the body to make enough (NHS). That is a supplement with a clear purpose, a clear dose and clear guidance.

My supplement-risk checklist

Before I recommend or personally use a supplement, I want clear answers.

Is there a real need? What problem is the supplement solving?
Is there relevant human evidence? Not just a biochemical theory or an influencer testimonial.
Is the useful dose stated? Be wary of proprietary blends that hide individual amounts.
Is the exact batch independently tested? Look for credible third-party certification relevant to the product and your circumstances; for example, Informed Sport batch-tests for substances prohibited in sport.
What else does the manufacturer produce? Shared facilities with high-risk products may deserve extra scrutiny.
Could it interact with medication or a health condition? Ask an appropriate clinician or pharmacist.
Can I keep a record? Photograph the label and batch number, and keep the receipt and certification details.

Third-party testing can lower risk. It cannot guarantee that a product is suitable, effective or completely risk-free.

The Strong Not Strict standard: food first where practical; supplements only for an identified purpose; effective doses disclosed; risks explained; no fear-based selling; and no promise that any product is completely risk-free.
