What Are the Side Effects of Thorne Collagen Plus?
Always consult your health practitioner if in doubt.
RiskLow Risk
Overview
•- All ingredients are GRAS with dosages well below safe upper limits (e.g., niacinamide <500 mg/day tolerable limit); no known contaminants from Thorne's GMP manufacturing.
•- Low interaction risk; curcumin may mildly inhibit CYP3A4, but at 250 mg dose, unlikely to affect common medications significantly.
•- Suitable for healthy adults; hyaluronic acid safe for pregnancy (Category B equivalent), but consult physician for collagen in first trimester.
•- Potential mild GI upset from collagen peptides in sensitive individuals; no major allergens like gluten, soy, or dairy present.
•- Long-term use supported by studies up to 12 months with no adverse effects at these doses; elderly may benefit without increased risk.
•- No contraindications for common conditions like diabetes or hypertension; monitor if on blood thinners due to curcumin's mild antiplatelet effect.
