Cell Protection

Cell protection is the shorthand for a group of nutrients and plant compounds bought for the same broad reason: the body is under constant oxidative pressure, and a handful of vitamins and minerals have an authorised role in protecting cells from it. Vitamin E, selenium, vitamin C, zinc, copper, manganese and riboflavin all contribute to the protection of cells from oxidative stress. That claim is permitted because the evidence behind it was assessed and accepted – it is worth knowing which nutrients carry it and which do not.

Alongside them sit the compounds that get talked about far more than they are regulated: glutathione, quercetin, alpha lipoic acid, resveratrol, astaxanthin, grape seed and pine bark extract, sulforaphane, NAC, NMN and NAD precursors, and Salvestrol. None of these carry an authorised health claim in the UK, so you will not find one made here. They are included because customers ask for them by name and buy them knowingly, not because we can tell you what they will do.

Only a short list of nutrients may legally be described as protecting cells from oxidative stress: vitamin E, vitamin C, selenium, zinc, copper, manganese and riboflavin. If a product is built on one of those, the claim on the box is authorised and means something specific.

Everything else in this category – glutathione, quercetin, resveratrol, NMN, sulforaphane, Salvestrol – sells on reputation rather than an approved claim. That is not a criticism of them, but it does mean the packaging has to stay quiet, and a product making bolder promises is the one to be sceptical about.

Selenium is the one people most often get wrong. It carries an authorised role in cell protection at a modest intake, and UK soils are low in it, so a supplement is reasonable. But the gap between a useful amount and too much is narrower than with most minerals, which is why reputable products sit around 100–200mcg rather than going higher.

Yeast-bound selenium and sodium selenite are the two common forms. If you already take a multivitamin, check what is in it before adding a standalone – the totals add up quickly.

Glutathione is the body's own compound, and swallowing it is not straightforward – standard capsules are broken down before much arrives. This is why liposomal and reduced forms exist and cost more, and Well Actually, Coyne and Balanced all sell them for that reason.

NAC takes the other route: it supplies a building block rather than the finished compound. Both approaches are legitimate and neither is proven superior, so buy on format and price rather than on which sounds more advanced.

NMN and nicotinamide riboside are precursors – raw material the body converts. The research is genuinely active but it is early, most of it is not in humans, and no health claim is authorised in the UK. Anyone telling you otherwise is ahead of the evidence.

Purity and dose are where these products differ. BioTech Life Sciences state a purity figure and sell by the gram; KIKI Health, Phytoceutics and Feel Supreme sell capsules, sometimes paired with resveratrol or astaxanthin. Compare cost per gram rather than cost per bottle, because bottle sizes vary enormously.

Cell protection: common questions

Which nutrients here have an approved claim?

Vitamin E, vitamin C, selenium, zinc, copper, manganese and riboflavin contribute to the protection of cells from oxidative stress. The plant compounds and NMN products do not carry an authorised claim.

Is there any point taking more than one of these?

Usually not. Most people are better served by one well-chosen product than by stacking several. Check your multivitamin first – it may already cover the selenium, zinc and vitamin E.

Why is liposomal glutathione so much dearer?

Plain glutathione is largely broken down during digestion. Liposomal and reduced forms are made to survive that, which costs more to produce. Whether the difference justifies the price is a judgement call.

What is Salvestrol?

Salvestrol is a branded range of concentrated plant compounds sourced from fruit and vegetables. It has a loyal following and we stock the full range, but no health claim is authorised for it and we do not make one.

Can I take these alongside prescribed medication?

Check with your GP or pharmacist first. NAC, quercetin and high-dose antioxidants can interact with some medicines, and anyone on treatment should ask before adding anything.
