You can eat normally on atorvastatin or rosuvastatin, and a diet lower in saturated fat and higher in fibre still lowers your LDL further on top of the statin. The main food rules are about grapefruit and alcohol. With atorvastatin, avoid large amounts of grapefruit juice. Rosuvastatin has no grapefruit warning. With simvastatin, avoid grapefruit juice altogether. On any statin, keep alcohol within low-risk limits.
The short version
Diet still matters: statins cut the cholesterol your liver makes, while food changes work in other ways, so the effects add up. Grapefruit: it depends on the statin (see the table below). Alcohol: heavy drinking raises the risk of liver side effects, so stay within 14 units a week. Supplements: check with a pharmacist first, especially St John's wort and red yeast rice. Muscle aches: real but less common than people think. Report them to your doctor rather than stopping on your own.
Talk to your doctor before changing your medication
This guide is general information, not medical advice. Don't stop, skip or change the dose of your statin because of anything here, including side effects you think it's causing. Talk to your doctor or pharmacist first: there's usually a way to adjust treatment, and NICE notes that any statin at any dose lowers heart and stroke risk. Your medicine's leaflet is the final word on what to avoid.
Why diet still matters on a statin
Statins lower LDL by slowing the liver's own cholesterol production. A moderate-intensity statin typically lowers LDL by 30 to 49%, and a high-intensity one by 50% or more, according to the 2026 ACC/AHA guideline. Many people still don't reach their goal on a statin alone, and that's where food comes in.
- Less saturated fat means less of the push that raises LDL in the first place. The NHS suggests cutting down on fatty meat, sausages and pies, butter, lard and ghee, cream, cheese, cakes and biscuits, and foods containing coconut or palm oil.
- More fibre, especially the soluble fibre in oats, barley, beans and lentils, binds cholesterol in the gut. In a pooled analysis of 67 trials, each extra gram a day lowered LDL by about 0.06 mmol/L (2 mg/dL).
- Unsaturated fats such as olive and rapeseed oil, nuts, seeds and oily fish are good replacements for saturated ones.
- Plant sterols and stanols (in fortified spreads, yoghurts and drinks) lower LDL by about 6 to 12% at 0.6 to 3.3 g a day. NICE doesn't advise taking them to prevent heart disease, so talk to your doctor if you're thinking of adding them.
NICE's advice to doctors is that if someone on a statin isn't reaching their target, they should check how and when the statin is being taken and encourage further diet and lifestyle improvements, alongside reviewing the dose. The UK targets are a more than 40% fall in non-HDL cholesterol for people who haven't had heart disease. For people who have, the target is LDL of 2.0 mmol/L (77 mg/dL) or less or non-HDL of 2.6 mmol/L (100 mg/dL) or less. The US goals are covered in our 2026 guidelines guide.

Grapefruit: the rules for each statin
Grapefruit juice can raise the level of some statins in your blood, which raises the risk of muscle side effects. How much it matters depends on which statin you take:
| Statin | What the official sources say | In practice |
|---|---|---|
| Atorvastatin (Lipitor) | FDA label: avoid large quantities, more than 1.2 litres of grapefruit juice a day. BNF: caution. NHS: no more than 1 or 2 small glasses a day. | A small glass now and then is generally fine. Don't drink a lot. |
| Rosuvastatin (Crestor) | No grapefruit warning on the FDA label, in the BNF or on the NHS page, which says you can eat as normal. | Grapefruit isn't a listed concern. |
| Simvastatin (Zocor) | FDA label: avoid grapefruit juice. BNF: manufacturer advises avoid. NHS: avoid drinking grapefruit juice. | Avoid grapefruit juice. |
| Pravastatin | No grapefruit warning in the BNF or on the NHS page. | Grapefruit isn't a listed concern. |
The labels talk mostly about the juice. The NHS's general statins page lists both "grapefruit or grapefruit juice", so if you eat a lot of fresh grapefruit, ask your pharmacist. If you take another statin or a combination tablet, check its leaflet.
Alcohol
- The FDA labels for atorvastatin, rosuvastatin and simvastatin all warn that people who drink substantial amounts of alcohol, or have a history of liver disease, may be at higher risk of liver injury. The patient leaflets ask you to tell your doctor if you drink more than 2 glasses of alcohol a day.
- The NHS medicine pages advise limiting alcohol on any statin because it can increase the risk of side effects such as liver problems.
- The 2026 ACC/AHA guideline lists alcohol among the things linked to a higher risk of statin-related muscle symptoms.
- The NHS low-risk limit is no more than 14 units a week, spread over 3 or more days, with several drink-free days.
Alcohol also raises triglycerides. If yours are high, see what to eat and cut for high triglycerides.
When to take it, and with food or without
- Atorvastatin and rosuvastatin can be taken at any time of day, with or without food, according to their FDA labels. Pick a time and keep to it.
- Simvastatin and pravastatin are usually taken in the evening, as the NHS and the simvastatin label say.
- Rosuvastatin and indigestion remedies: antacids containing aluminium and magnesium hydroxide can halve how much rosuvastatin you absorb. The label says to take rosuvastatin at least 2 hours before the antacid.
Supplements to check with your doctor or pharmacist first
NICE asks doctors to warn people that "other drugs, some foods (for example, grapefruit juice) and some supplements may interfere with statins". Check before starting any of these:
- St John's wort lowers the amount of atorvastatin and simvastatin in your blood (BNF), so the statin may work less well.
- Red yeast rice contains monacolin K, which the US National Center for Complementary and Integrative Health says is "structurally identical" to the statin drug lovastatin. Taking it alongside a statin is effectively doubling up. Some products have also been found contaminated with citrinin, a toxin that can damage the kidneys.
- Niacin (nicotinic acid) at cholesterol-lowering doses of 1 g a day or more has been linked to muscle damage when combined with statins, according to the labels. The amounts in a standard multivitamin are much lower.
- "Cholesterol-lowering" supplements in general: the 2026 ACC/AHA guideline recommends against using dietary supplements to lower LDL or triglycerides.
Food sources of nutrients, such as oily fish, nuts and fibre-rich foods, don't carry these interaction warnings.
Muscle aches: what's really going on
Muscle pain is the side effect people worry about most. It's real for some people, but large trials show it's much less often caused by the statin than people assume:
- A 2022 analysis in The Lancet of 19 blinded trials (about 124,000 people) found muscle pain or weakness in 27.1% of people on a statin and 26.6% on a placebo. In the first year, only about 1 in 15 muscle complaints among people on a statin was actually caused by it. After the first year there was no clear difference. Over 90% of muscle symptoms reported on statins weren't due to the statin.
- In the UK StatinWISE trial, 200 people who had stopped or were thinking of stopping statins because of muscle symptoms took atorvastatin 20 mg and a placebo in alternating, blinded two-month periods. Their muscle symptom scores were no different on the statin and the placebo, and two-thirds decided to restart a statin.
- The risk is higher with higher doses, age 65 or over, an underactive thyroid, kidney or liver disease, alcohol, very vigorous exercise and some interacting medicines, according to the 2026 guideline.
What to do: NICE advises people on a statin to seek medical advice if they get unexplained muscle pain, tenderness or weakness. Your doctor may check a blood test called creatine kinase. If the statin does seem to be the cause, the options NICE lists include pausing and trying again once symptoms settle, switching to a different statin, or lowering the dose, all decided with your doctor. If you have severe muscle pain or weakness, the NHS says to call 111.
Does CoQ10 help?
Honestly, it's unproven. Coenzyme Q10 is often suggested because statins lower its levels in the blood, but trials of CoQ10 supplements for statin muscle pain have been small and short, and their pooled results disagree:
- Meta-analyses in 2015 (6 trials, 302 people) and 2020 (7 trials, 321 people) found no significant benefit for muscle pain, and no effect on whether people stayed on their statin.
- Meta-analyses in 2018 (12 trials, 575 people) and 2025 (7 trials, 389 people) found that it reduced muscle symptoms, with the 2025 authors calling for more research.
If you want to try it, mention it to your doctor or pharmacist, as with any supplement. It's not a reason to put up with symptoms rather than report them.
Questions to ask your doctor or pharmacist
- Does my statin interact with grapefruit, alcohol, or anything else I take?
- What LDL or non-HDL level are we aiming for, and when will it be re-checked?
- Would changing my diet let us stay on this dose, or is a higher dose or an added medicine likely?
- I've had muscle aches. Should we check them, and what are the options if the statin is the cause?
- Have I had my Lp(a) measured?

Frequently asked questions
Can I eat grapefruit if I take rosuvastatin?
Rosuvastatin has no grapefruit warning on its FDA label, in the BNF or on the NHS medicine page, which says you can eat as normal. Grapefruit is a bigger concern with simvastatin and, in large amounts, atorvastatin. Check your own medicine's leaflet if you take a combination tablet.
How much grapefruit juice can I have on atorvastatin?
The NHS says no more than 1 or 2 small glasses of grapefruit juice a day. The FDA label says to avoid large quantities, more than 1.2 litres a day, because it can raise atorvastatin levels and the risk of muscle side effects.
Can I drink alcohol while taking statins?
Usually yes, in moderation. The NHS advises limiting alcohol on statins because heavy drinking raises the risk of side effects such as liver problems, and the FDA leaflets ask you to tell your doctor if you drink more than 2 glasses a day. The NHS low-risk limit is 14 units a week, spread over 3 or more days.
What foods should you avoid on statins?
There's no long list. The main ones are grapefruit juice with simvastatin (avoid) and atorvastatin (not in large amounts). For your cholesterol, it also helps to cut down on foods high in saturated fat, such as fatty meat, butter, cream, cheese, cakes and biscuits, and foods made with coconut or palm oil.
Do I still need to watch my diet if I'm on a statin?
Yes. Statins and diet work in different ways, so their effects add up. NICE advises doctors to encourage continued diet and lifestyle improvements when someone on a statin isn't reaching their cholesterol target, and a better diet also helps blood pressure, weight and blood sugar.
Does CoQ10 help with statin muscle pain?
It's unproven. Four meta-analyses of small, short trials disagree: two found no significant benefit and two found a reduction in muscle symptoms. Large blinded trials also show most muscle aches on statins aren't caused by the statin. Report muscle symptoms to your doctor rather than stopping your statin, and mention any supplement you plan to take.
Are statins banned in Europe?
No. Statins are prescribed across Europe. In the UK, the NHS prescribes atorvastatin, fluvastatin, pravastatin, rosuvastatin and simvastatin, and NICE recommends atorvastatin as the first statin for most people who need one to prevent heart disease.
What time of day should I take atorvastatin or rosuvastatin?
Either can be taken at any time of day, with or without food, according to their FDA labels. The NHS suggests taking it at the same time each day. Simvastatin and pravastatin are usually taken in the evening.
See whether your statin and diet are working
Your doctor will usually re-check cholesterol a few months after you start or change a statin. Heart Tracker charts your total cholesterol, LDL, HDL and triglycerides between visits. Logging meals shows how much saturated fat and fibre you're actually eating, so you can see which changes are adding to your statin's effect. Free and ad-supported, with no account needed.
