What supplements fight chronic inflammation?

Chronic inflammation is a number: what the phrase means in a person without a disease, how it is measured, and the top of the league table, where the rows are free and the reductions are large

What supplements fight chronic inflammation is a question that has to be anchored to a number before it can be answered, because chronic inflammation is a phrase the shelf uses for a feeling and the research uses for a measurement. In a person without an inflammatory disease, chronic inflammation means a persistently raised level of C-reactive protein, the marker the liver releases in response to inflammatory signalling, measured on a blood test a doctor orders and read against a range in which the low-grade elevation the phrase refers to sits well below the levels an infection or an inflammatory disease produces. The useful property of a number is that it can be lowered and the lowering measured, so that every intervention sold or prescribed for chronic inflammation can be placed in a league table by how much it lowered the number in trials, and the table, rather than the shelf, answers the question.

The top of the table is not for sale. The largest reductions in C-reactive protein in the intervention trials come from weight loss, and especially from the loss of visceral fat, the fat around the organs, which is itself a source of inflammatory signalling, so that a person carrying it who loses it lowers the number by more than any other single intervention. Regular aerobic exercise lowers it independently of weight, with the trials finding the reduction in people who train regularly whether or not the scale moves. Stopping smoking lowers it, because smoking is among the largest avoidable sources of inflammatory signalling. Sleep lowers it, with short sleep raising the number in the restriction studies and restored sleep lowering it. Moderated alcohol sits beside them, with heavy drinking raising the number. The lifestyle literature on C-reactive protein places these five at the top of the table by a wide margin, and a person who asks what supplement fights chronic inflammation while carrying visceral fat, smoking, sleeping six hours or drinking most evenings is asking for a bottom row while ignoring the top five.

One prescribed row sits beside the free ones. Statins lower C-reactive protein as well as cholesterol, which is part of why they reduce cardiovascular events, and a doctor who finds a raised number alongside a raised cardiovascular risk may prescribe one; it is a doctor's row, read with the lipid profile and the risk calculators, and it is mentioned here because it is the one row on the table below the lifestyle five that has outcome evidence, which no supplement row has.

A number defined and the top of its table, free and large, and the supplement rows at the bottom, the inflammation that is a disease and a doctor's, the lifter's session placed, and the worked example with no row, which is the next section.

The supplement rows at the bottom of the table: omega-3 and curcumin small, vitamin D in the deficient, the rest with nothing measured; the inflammation that is a disease and a doctor's; the lifter's session; the worked example; and the verdict

The supplement rows sit at the bottom of the table, and two of them have a number. Omega-3 EPA and DHA at a few grams a day lowered C-reactive protein by a small margin in the meta-analyses, with the effect clearer in people whose number was raised to begin with and in those eating no oily fish, and with the omega-3 claims on the register being for heart function and triglycerides rather than for inflammation, which is why the row is small and honest rather than the headline the shelf makes it. Curcumin, taken with an absorption enhancer because the plain spice is barely absorbed, lowered C-reactive protein by a small margin in some trials and not in others, in people with raised numbers, with no authorised claim and a pharmacist's question about interactions for anyone on an anticoagulant. Vitamin D lowered the number only in people who were deficient, which through the UK winter is a large share, and the row reads as a corrected shortfall rather than an anti-inflammatory effect. Those three are the supplement rows with a measurement, and all three are small beside the top of the table.

The rest of the shelf has no row, because no trial of size measured a reduction. The anti-inflammatory blends that combine turmeric, ginger, boswellia and a dozen extracts at undeclared doses were never trialled as blends; the greens powders, the antioxidant complexes and the high-dose vitamin C and E have no C-reactive protein reduction to show and, in the lifter's case, blunt the training adaptation the session's own inflammation produces; the collagen, the mushroom extracts and the adaptogens sold for inflammation have nothing measured. A product sold for chronic inflammation that has no C-reactive protein trial has made a claim about a number it never read, and the table has no row for it.

The inflammation that is a disease is a doctor's and is stated plainly, because the shelf sells to it with the same products. Joints that are swollen, warm or stiff for more than an hour in the morning, a persistent fever, unexplained weight loss, a rash with joint pain, a gut that bleeds or has changed its habit, or fatigue with any of these is an inflammatory disease until a doctor says otherwise, with effective treatment that a supplement delays; a C-reactive protein that is high rather than low-grade is a doctor's number too. The lifter's own session belongs on the table for a different reason: a hard session raises inflammatory markers for a day or two as part of the adaptation, which is acute and wanted, and a product that lowers it has lowered the adaptation; chronic inflammation is the number at rest between sessions, and the lifter who trains regularly has already lowered it by the second row of the table.

The worked example is placed with no row at all, which is the honest position: {FL}, 1500mg magnesium bisglycinate stated as 300mg elemental at 80% NRV, two capsules with the evening meal, with authorised claims for normal muscle function, normal psychological function and the reduction of tiredness and fatigue, no inflammation claim and no C-reactive protein trial of size, which this page states rather than invents, batch tested for lead, mercury, arsenic and cadmium, UK made, 180 capsules for £19.99 at 22p a day, taken for a plate the survey finds a share of adults short of. The full label breakdown is here.

The verdict: chronic inflammation is a number, and the league table of what lowers it is topped by rows that are free, weight and visceral fat loss, regular exercise, stopping smoking, sleep and moderated alcohol, with a statin as a doctor's row beside them. The supplement rows sit at the bottom: omega-3 and curcumin with small measured reductions, vitamin D in the deficient, and the blends, greens and antioxidant complexes with no measurement at all. A disease pattern is a doctor's, the session's inflammation is wanted, and a person who asks for a supplement while ignoring the top five has read the table from the wrong end.

What to check on the label

Questions people also ask

What is the strongest anti-inflammatory supplement?

None is strong by the number the phrase refers to: chronic inflammation in a person without a disease is a raised C-reactive protein, and the trials that lowered it most were weight loss and especially visceral fat loss, regular aerobic exercise, stopping smoking, sleep and moderated alcohol, with statins a prescribed row beside them; the supplement rows sit at the bottom, omega-3 at a few grams with a small reduction in the meta-analyses, curcumin with an absorption enhancer with a small reduction in some trials, vitamin D in the deficient, and the blends and antioxidant complexes with nothing measured.

How do I know if I have chronic inflammation?

By a blood test rather than a feeling: a doctor measures C-reactive protein and reads it against a range in which the low-grade elevation the phrase refers to sits well below the levels an infection or an inflammatory disease produces, and a high rather than low-grade number is a doctor's question; joints that are swollen, warm or stiff for more than an hour in the morning, a persistent fever, unexplained weight loss, a rash with joint pain, a changed or bleeding gut, or fatigue with any of these is an inflammatory disease until a doctor says otherwise, with effective treatment a supplement delays.

Does omega-3 reduce inflammation?

By a small margin: omega-3 EPA and DHA at a few grams a day lowered C-reactive protein by a small amount in the meta-analyses, clearer in people whose number was raised and in those eating no oily fish, and the authorised claims on the register are for normal heart function and triglycerides rather than for inflammation, so the row is small and honest; a person eating two portions of oily fish a week has the fatty acids already, and the top of the league table, visceral fat, exercise, smoking and sleep, moves the number by far more.

Does exercise cause or reduce inflammation?

Both, on two different clocks: a hard session raises inflammatory markers for a day or two as part of the adaptation, which is acute and wanted, and a product that lowers it, the high-dose antioxidant complexes especially, lowers the adaptation the session was for; chronic inflammation is the number at rest between sessions, and regular training lowers it independently of weight in the trials, which puts the lifter who trains regularly on the second row of the league table before any product is considered.

Does magnesium reduce inflammation?

It has no inflammation claim and no C-reactive protein trial of size, which this page states rather than invents; magnesium has authorised claims for normal muscle function, normal psychological function and the reduction of tiredness and fatigue, and the worked example is 300mg elemental at 80% NRV in two capsules with the evening meal for 22p a day, batch tested for four metals and UK made, taken for a plate the national survey finds a share of adults short of, with no row on the league table and none claimed.
