An Important Dosage Correction Before You Start
This product provides 3000mcg RAE (10,000 IU) of preformed vitamin A as retinyl acetate per tablet. As covered in detail in our vitamin A safety guide, the NHS advises no more than 1.5mg (1,500mcg) daily from supplements combined. The standard one-tablet daily dose recommended on this product provides double that limit, on its own, before counting any other source of vitamin A such as a multivitamin or regular liver consumption.
It’s worth being direct about the “gentler formulation” framing: retinyl acetate is a preformed vitamin A ester, similar in accumulation risk to retinyl palmitate — there isn’t a meaningful safety difference between these preformed forms at this dose. The genuine safety distinction is between preformed vitamin A (retinol, retinyl acetate, retinyl palmitate) and beta-carotene, which the body converts to vitamin A only as needed, without the same accumulation risk. This product uses the preformed type.
Because a tablet can’t practically be split for accurate dosing, daily use of a full tablet isn’t appropriate for ongoing, regular supplementation under NHS guidance. This product is better suited to occasional or short-term use kept within your weekly average, or specifically for a confirmed deficiency under a GP’s direct guidance and monitoring — not a default daily addition to your routine. If you want a vitamin A product suited to regular daily use within the NHS limit, a lower-dose product or beta-carotene is generally the more appropriate choice.
If you are pregnant or planning pregnancy, avoid this product entirely. This is specific NHS guidance for preformed vitamin A supplements at any dose, given the association between high intake and birth defect risk.
Vitamin A has established, EU-authorised roles in normal iron metabolism, skin maintenance, vision, and immune function — genuine roles, though this doesn’t change the dosage consideration above. Signs of excess vitamin A can include skin irritation, nausea, headaches, and — with sustained excess — liver effects that can develop silently; speak to your GP if you notice any of these. Vegan, non-GMO, gluten and dairy-free, manufactured to GMP standards. Speak to your GP before use if you take regular medication, have an existing health condition, or are pregnant or planning pregnancy — and specifically before taking this product daily on an ongoing basis.
