Naturopathic and Integrative Care for Autoimmune Conditions: What Is Known and Cautions
What research says about diets, supplements and whole-system naturopathic care for autoimmune conditions, and why immune-modulating medicines should never be stopped on your own.
Content last updated . This page has not been medically reviewed.
Living with an autoimmune condition can be unpredictable, and many people want to add food, supplement or lifestyle approaches. This page is information only. Never stop or change an immune-modulating medicine, steroid, thyroid medicine or biologic on the advice of a website or a practitioner without your prescribing specialist agreeing.
Why medical treatment comes first
In an autoimmune disease, the immune system attacks healthy cells in organs and tissues by mistake. MedlinePlus says there are more than 80 types, and that there is usually not a specific test to show whether you have a certain one. [1] In most cases, the goal of treatment is to suppress, or slow down, the immune system. [1] The US National Center for Complementary and Integrative Health (NCCIH) says medical treatment for rheumatoid arthritis can delay or prevent joint damage and does not just treat symptoms. [2] It advises not substituting other approaches for treatments your provider prescribes. [2] The NHS describes underactive thyroid from Hashimoto's disease as usually treated with medicine that replaces the missing thyroid hormone. [3]NCCIH advises seeing a provider promptly for joint symptoms that might be rheumatoid arthritis. [2] See never delay medical care.
What research shows
| Approach | What the source found | Evidence label |
|---|---|---|
| Vitamin D or marine omega-3 supplements to prevent autoimmune disease in older adults (VITAL trial) | A randomized, placebo-controlled trial of 25,871 adults (men aged 50 and over, women 55 and over) found vitamin D for five years reduced autoimmune disease by 22%; omega-3 reduced it by 15%, which was not statistically significant. [4] Two years after the trial ended the vitamin D effect had dissipated, while the omega-3 effect was described as sustained. [5] | Mixed; prevention only, not treatment of existing disease |
| Autoimmune protocol (AIP) elimination diet | A single-arm pilot in nine adults with RA followed an 8-week AIP diet after 4 weeks of usual diet; the authors say the findings support further controlled trials. [6] A 28-person Hashimoto's study found that one thyroid antibody level (aTPO) increased significantly, and body weight fell, suggesting a calorie deficit. [7] | Insufficient evidence (small, uncontrolled) |
| Special diets for rheumatoid arthritis | NCCIH says the effects of vegetarian, Mediterranean or elimination diets are uncertain because little research has been done. [2] | Insufficient evidence |
| Whole-system naturopathic or functional medicine care | Proper evidence not found. We searched PubMed for naturopathic care with autoimmune terms (eight records, none a trial of whole-system care) and for randomized trials of functional medicine in autoimmune, Hashimoto's, rheumatoid or lupus conditions (no records). | Insufficient evidence |
| Mind-body practices for RA | NCCIH says the amount of research is too small to reach conclusions about symptom relief. [2] Four mindfulness studies found some improvement in subjective symptoms such as pain or coping. [2] | Insufficient evidence |
An uncontrolled pilot, where everyone gets the diet, cannot separate the effect of the diet from expectation, weight loss, or the natural ups and downs of these illnesses. A weight-loss side effect can also be unwanted. NCCIH notes some people on special diets lost weight they did not intend to lose, and restrictive diets that eliminate major food groups may risk nutritional deficiencies. [2] Anyone with an eating-disorder history, a child, or a person who is pregnant should have a clinician or dietitian involved first.
Tests and cure claims
Panels sold to "find the root cause" of autoimmunity are covered in tests sold in integrative practice and over-testing and false positives. Claims that a diet or supplement cures an autoimmune disease are checked on this claim check. Gut-based claims are covered in leaky gut cleanses and gut tests.Who provides care
MedlinePlus advises seeing a specialist who deals with the symptoms that bother you most, for example a dermatologist for a rash. [1] Naturopathic doctors, dietitians and other clinicians may support diet and lifestyle; their training, licensing and scope of practice differ by place, covered in credentials and scope of practice. Tell every clinician what the others recommend: see coordinating complementary and medical care. For immune-health basics see immunodeficiency and autoimmune conditions.Frequently asked questions
Can diet cure an autoimmune disease?
We found no source showing that. Small pilot studies of an elimination diet were uncontrolled, and NCCIH says the effects of special diets on RA are uncertain. [6] [2]
Can I stop my medicine if I follow a natural protocol?
No. NCCIH advises not substituting other approaches for prescribed treatment. [2] Talk to your prescriber before any change.
Does vitamin D prevent autoimmune disease?
In the VITAL trial, vitamin D reduced new autoimmune disease over five years, but the effect faded after supplementation stopped, and the trial studied prevention in older adults, not treatment. [4] [5]
Is the autoimmune protocol diet proven?
Not by the studies we read: they were small and uncontrolled, and one found antibody levels rising in Hashimoto's. [6] [7]
Is echinacea a good choice for immune support if I have an autoimmune condition?
Ask your specialist first. NCCIH says there are theoretical reasons to suspect echinacea might interact with immunosuppressants. [8]
