    Quality products for Optimal Health

    This has no "real" flavor. It is simply buffered vitamin C. It is bland but that's ok because I choose quality over flavor. Drink up and then move on to your preferred beverage. Or add to a smoothie and it'll be just fine. Thorne provides superior products aimed at optimizing your health. This is the best choice for me!

    Easy to consume, clean product.

    I have repeat ordered Thorne's vitamin C, as for me it is the best supplier of clean vitamin C, no additives or fillers. Having a 5g daily dose with 200ml water is easy and basically tasteless. Best way to get higher dose vitamin C, and the buffered protocol works very well for no reactions.

    Great product.

    I mix this with a fruit drink to take it. It mixes easily and doesn't add any unpleasant taste. I've been using this for months now with great results. I work in a public elementary school. While others are out sick, I've not missed one school day this whole year. Those are results I like to see. I would recommend this product.

FAQs

Is Thorne vitamin C good?

Is it okay to take calcium, magnesium, and vitamin C together?
