What Customers Are Saying
Based on 1 review
Been taking these Windmill Vitamin C tablets for about 3 months now and I'm really impressed with the quality for the price. At $9.99 for 100 tablets, you can't beat the value compared to some of the fancier brands at the pharmacy. I take one every morning with breakfast and haven't had any stomach upset like I've experienced with other vitamin C supplements in the past. My doctor recommended I boost my vitamin C intake and these 500mg tablets are the perfect dose - not too much, not too little. The tablets are easy to swallow and don't have any weird aftertaste. Since starting these, I feel like my energy levels have been more consistent throughout the day. Shipping was super fast too, arrived in just 2 days. Definitely will be reordering when I run out!
