What is inside an ibuprofen from Sainsbury's and what are healthy alternatives

The short version: a Sainsbury's ibuprofen tablet is mostly the drug plus standard filler chemicals, and for most everyday pain the healthier alternative is to skip the pill and address the root cause.

A standard Sainsbury's ibuprofen tablet (typically 200 mg or 400 mg) contains the active ingredient ibuprofen plus a handful of inactive "excipients" that hold the pill together and help it dissolve. The evidence here does not list the exact Sainsbury's formula, but the excipients are almost certainly the same ones used in every generic ibuprofen tablet: lactose (or microcrystalline cellulose) as a filler, povidone as a binder, croscarmellose sodium or sodium starch glycolate as a disintegrant to make the tablet break apart in your stomach, and magnesium stearate as a lubricant for the manufacturing machine [1, 2]. Some formulations also include colloidal silica to improve powder flow [2]. None of these are toxic at the tiny amounts in one tablet, but if you have a lactose intolerance or a sensitivity to any of them, they can cause mild bloating or stomach upset.

The real question is whether you should take ibuprofen at all. The evidence on its safety for short-term use is mixed. A meta-analysis of eight placebo-controlled trials found that over-the-counter doses (up to 1200 mg per day for up to 10 days) had a side-effect profile similar to placebo, with about 4% of users reporting gastrointestinal issues [7]. But a separate review of NSAID risks notes that even short-term use can raise blood pressure, worsen kidney function in people with underlying kidney disease, and increase the risk of stomach bleeding, especially if you are over 65 or take blood thinners [5]. The risk is low for a healthy person taking it once or twice, but it is not zero.

For healthy alternatives, the evidence points strongly to non-drug approaches first. For osteoarthritis or chronic joint pain, exercise therapy (including walking, Tai Chi, and aquatic therapy) reduces pain by about as much as ibuprofen does, with no side effects [15, 17, 19, 21]. A 2024 systematic review of four trials with over 1,300 people found that exercise-based therapies significantly improved pain and function in knee osteoarthritis [15]. For acute muscle or headache pain, ice or heat, gentle stretching, and addressing the cause (poor posture, dehydration, lack of sleep) are safer first steps. If you need a drug, paracetamol (acetaminophen) is generally safer for the stomach than ibuprofen, though it carries its own liver risk if you take more than 4 grams per day or drink alcohol regularly [10, 11]. For inflammatory pain like a sprain or arthritis flare, ibuprofen is more effective than paracetamol because it directly reduces inflammation, but that benefit comes with the stomach and kidney trade-off.

My call: For a healthy adult with occasional pain, a single ibuprofen is low-risk, but the evidence does not support it as a default. The healthier alternative is almost always a non-drug approach first. If you must take a pill, paracetamol is safer for the stomach, ibuprofen is better for inflammation, and both should be used for the shortest time possible. Confidence: moderate — the safety data on short-term OTC ibuprofen is decent but comes mostly from industry-funded trials, and the long-term risks of even occasional use are not well studied in healthy populations.
