"Berberine supports healthy blood sugar and cholesterol"
Clinical trials showing benefit often use 500mg two to three times a day; a once-daily 500mg product may fall short of that studied protocol.
Consumer advice
Don't treat this as a single product decision - click into the specific item you want (e.g., Creatine or Magnesium Glycinate) and check its actual supplement facts panel for per-serving doses. Thorne is generally a credible brand (NSF Certified for Sport on many SKUs, no wild proprietary blends visible here), but price-per-serving varies a lot across their catalog, so compare cost per dose against a plain generic version (e.g., creatine monohydrate powder) before assuming the premium price buys extra benefit.

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.

Possible side effects
- High blood calcium from vitamin D toxicity can lead to nausea, vomiting, muscle weakness, and other symptoms.
Serious risks
