THORNE Vitamin C – High-Quality, Effective, and Gentle on the Stomach! I’ve been taking THORNE Vitamin C for a while now, and it has quickly become my go-to vitamin C supplement. THORNE is known for its high-quality, science-backed supplements, and this one definitely lives up to the reputation. Pure & High-Quality Ingredients One of the things I appreciate most is that THORNE uses pure, well-sourced ingredients without unnecessary additives, artificial fillers, or allergens. It’s free from gluten, dairy, and soy, making it a great choice for those with sensitivities. Easy on the Stomach Unlike some other vitamin C supplements that can cause stomach irritation, this one is gentle and well-tolerated, even when taken on an empty stomach. No bloating or discomfort, which is a huge plus! Effective Immune & Antioxidant Support I’ve noticed an improvement in my immune health and overall energy levels since taking this supplement regularly. It also supports skin health and collagen production, making it a great all-around vitamin for wellness. Capsule Form – Convenient & Absorbable The capsule form is easy to swallow, and it absorbs well without the chalky taste or acidity that comes with some powdered vitamin C options.

ENHANCE YOUR COLLAGEN!

Victoria ColmeneroOctober 21, 2025

I’ve been using it for a short time I’m not sure of the results. But it’s easy to swallow since I have a little trouble with that. Not too large. The Cost is worth it! easy on the tummy. I take it in the morning with my coffee and breakfast to enhance my collagen powder supplement. You’d like it. No flavor which is winner. Read more

Smaller doses are better for absorption!

DDBSeptember 9, 2025

This is an excellent product and I like the lower dosage per tablet, since we only absorb 200-500mg per dose, which remains in our system around only 5 hours, and the rest we pee out. We take one tablet morning and again in the evening, several hours before bed so we're not having to make a lot of bathroom trips during the night. Use your own good judgement! Read more
