What does single-ingredient mean?
That the product contains one active ingredient rather than a blend, with as few excipients as the capsule allows. Full ingredients are on each product page.
What is buffered vitamin C?
Vitamin C combined with a mineral salt, which makes it less acidic than plain ascorbic acid. Some people find it easier on the stomach.
Are the capsules suitable for vegetarians?
It varies by product — capsule shells differ. Each pack states this.
Can I take several together?
Often, but avoid duplicating the same nutrient across products. Check with your GP or pharmacist if you take prescribed medication.
Are they free from common allergens?
The excipient lists are deliberately short, but check the individual product if you have a specific allergy.
