Magnesium
Magnesium from food poses no health risk in healthy people, because the kidneys clear the excess. High doses from supplements or medications can cause diarrhea, nausea and abdominal cramping, and very high doses can lead to toxicity.
Possible side effects
- High doses from supplements or medications can cause diarrhea, nausea, and abdominal cramping.
- Magnesium carbonate, chloride, gluconate, and oxide are the forms most commonly reported to cause diarrhea.
Serious risks
- Very high doses can lead to magnesium toxicity, with low blood pressure, vomiting, difficulty breathing, irregular heartbeat, cardiac arrest and other signs.
- A few cases of fatal hypermagnesemia have been reported.
- Very large doses of magnesium-containing laxatives and antacids have been associated with magnesium toxicity.
- The risk of toxicity increases with impaired kidney function or kidney failure.
Avoid or ask a doctor first if
- People with impaired kidney function or kidney failure face higher risk of magnesium toxicity.
- People taking medications regularly should discuss their magnesium intake with their health care providers.
Medication interactions
- Magnesium may interact with oral bisphosphonates, tetracyclines, and quinolone antibiotics.
- Some medications, including diuretics and proton pump inhibitors, can affect magnesium status.
Upper limit: 350 mg a day for adults 19+. This label lists Not specified on homepage; requires product page review.

Probiotics
Probiotics are unlikely to cause harm in healthy people, and side effects are usually minor. They have been linked to bacteremia, fungemia, and infections that caused severe illness, mostly in people who were severely ill or immunocompromised.
Possible side effects
- Side effects are usually minor and consist of self-limited gastrointestinal symptoms such as gas.
Serious risks
- Probiotic use has been linked to bacteremia, fungemia, and infections that led to severe illness, mostly in severely ill or immunocompromised people.
- Severe or fatal infections have been reported in premature infants given probiotics, and the FDA has warned health care providers.
- In a Boston ICU analysis, 6 of 522 patients given LGG had the ingested LGG found in their blood, versus 2 of 21,652 who did not receive it.
- Possible harms include infections, harmful substances produced by the probiotic microorganisms, and transfer of antibiotic resistance genes.
- Some products have contained microorganisms not listed on the label, which in some instances may pose serious health risks.
Avoid or ask a doctor first if
- For high-risk people such as premature infants or seriously ill hospital patients, the risks of probiotics should be carefully weighed against their benefits.
- For people with compromised immune function or other serious underlying diseases, the WGO advises restricting probiotic use to strains and indications with proven efficacy.
- Consult a health care provider before taking a probiotic supplement, especially with health problems. Anyone with a serious underlying condition should be monitored closely.

Ashwagandha
ODS says ashwagandha appears well tolerated for up to about 3 months, but long-term safety isn't known. It names liver and thyroid concerns, possible medication interactions, and groups who should avoid it, including pregnant women.

- NCCIH describes liver injury cases linked to ashwagandha supplements and calls them rare.
- Three case reports describe thyrotoxicosis in women taking ashwagandha extract.
- In all three thyrotoxicosis cases, stopping ashwagandha resolved the symptoms.
Avoid or ask a doctor first if
- Some experts advise pregnant women not to use ashwagandha, because some reports suggest it could cause spontaneous abortion.
- NCCIH says to avoid ashwagandha during pregnancy and not to use it while breastfeeding.
- NCCIH does not recommend it before surgery or for people with autoimmune or thyroid disorders.
- People with hormone-sensitive prostate cancer should avoid it because it may raise testosterone.
