My Daily Dose if C!

I love this powder form of Vit C. I take it almost every night before bed. I trust the quality of this brand as I've been taking their magnesium capsules for several years. I've tried other powder Vit C but this one taste yummy. So far I've not had any stomach issues as well.

Vit. C

I really like this buffered vitamin C powder — it delivers a high dose of vitamin C in a formulation that’s gentle on the stomach thanks to the buffered mineral ascorbates. The natural passionfruit flavour and slight sweetness make it easy to mix into water or juice, and it’s great for supporting immune health and antioxidant needs. Many people appreciate that it’s free of common allergens and easy to digest, which makes it a reliable choice for daily use.

Product Review: Kirkman Labs Buffered Vitamin C Powder – Passion Fruit I’ve been using Kirkman Labs’ Buffered Vitamin C Powder (Passion Fruit flavor) for a few weeks now, and I’m genuinely impressed with the results. The powder dissolves easily in water and has a pleasantly mild passion fruit taste — not too sweet, not too sour. It’s a great option for people who have sensitive stomachs, as the buffered formula is gentle and doesn’t cause any irritation or acidity like some other vitamin C supplements. What I also appreciate is that it’s free of common allergens (like gluten, dairy, and soy), which makes it suitable for people with dietary restrictions. I take it daily, and I’ve noticed an improvement in my immune resilience and energy levels, especially during the colder months. The product comes in a well-sealed container with a measuring scoop, making it easy to dose accurately. One container lasts quite a long time, so it’s also good value for the price. Overall, I highly recommend this product if you're looking for a high-quality, stomach-friendly vitamin C supplement with a nice flavor!

We always keep some of the vit c for back up to take when we feel the onset of getting a cold/flu. Works like a charm every time.
