How we write about supplements

In Great Britain a health claim may only be used if it appears on the official nutrition and health claims register. We stay inside it. That means two claims are used on this site and no others: DHA contributes to the maintenance of normal brain function, at a daily intake of 250mg; and vitamin B12 contributes to normal psychological function and to the reduction of tiredness and fatigue.

Our other ingredients — phosphatidylserine, choline, lion’s mane and astaxanthin — carry no authorised claim. We describe what they are and where they are found, and we say plainly that no claim is permitted for them. That is why our pages read more cautiously than much of the market.

Each guide is written by our editorial team, checked against the authorised claims register and against public NHS, British Dietetic Association and GOV.UK guidance, then dated. The “last checked” line at the top of a page is the date the page was last read through against those sources, not the date it was first written.

References are listed at the foot of each guide and link to the original source so you can read it yourself. If we cannot support a statement with a real source, we remove the statement rather than soften it.

We publish no star rating and no customer quotes on this site yet, because we will only publish reviews we can verify came from real Enervia orders. Where we summarise the feedback our support team receives, we say plainly that is what it is. As verified purchase feedback accumulates we will publish it with the bundle bought and how long the person had been taking it — including the unflattering ones.

Individual experiences with any food supplement vary, and no review is a promise of a result for you.

Several of our pages say that food and sleep beat any capsule, that a cheaper single-ingredient supplement may suit you better, or that a symptom belongs with a GP rather than a supplement order. Those sections are deliberate, and they stay in even when they cost us sales.

Enervia is not suitable for everyone. It contains fish, so it is unsuitable for anyone with a fish allergy and for vegetarians and vegans, it is not for under-18s, and anyone pregnant, breastfeeding or taking anticoagulant medication should speak to a GP or pharmacist first.

If you find something on this site that is wrong, out of date or overstated, email support@getenervia.co.uk. We will correct it and update the checked date on the page. If you have seen Enervia advertised somewhere with celebrity endorsements or medical claims, that advert is not ours — please send it to the same address so we can report it.
