What customers say
Customers appreciate Reacta-C for its 24-hour support, gentle effect on the stomach, and high quality. Many users report improved skin clarity and overall health, with fewer colds and flu. The product is praised for its natural ingredients and ease of swallowing, although some find the capsules large. While generally well-received, there are concerns about potential side effects from strontium. Users recommend it for immune support and skin health, noting its effectiveness in combination with other supplements.

Buffered vitamin C - no stomach upset even at higher doses
Verified purchase
Regular ascorbic acid gives me stomach issues if I take more than 500mg at once. Reacta-C is a buffered, pH-neutral form of vitamin C and I can take it without any of that. It also stays in the bloodstream longer than plain ascorbic acid, which makes sense from an absorption standpoint. I take it when I feel something coming on or after long flights and it does what I want it to do. Solaray is a brand I trust. These caps are easy to take and the 120-count bottle lasts a while.

Vitamin C with Bioflavonoids is a Good Combo
Verified purchase
I take one capsule every evening for eye, skin, and tissue support. Solaray has been around a long time and always make good quality products. These capsules are a little big but I swallow them fine. I prefer this to a product containing just vitamin C because bioflavonoids are very synergistic with vitamin C and provide tremendous health benefits on their own.

Premium Vitamin C with Enhanced Absorption
Verified purchase
Solaray Reacta-C is my go-to vitamin C supplement for reliable immune support and antioxidant protection! The 500 mg potency in these easy-to-swallow VegCaps provides just the right daily dose, while the added bioflavonoids and natural co-factors dramatically improve absorption. Unlike cheaper ascorbic acid formulas, this one never causes stomach discomfort. The 120-count bottle offers excellent value – I've noticed fewer seasonal illnesses and brighter skin since making this part of my routine. A truly well-designed supplement that delivers real results

Good quality product... Recommend it. No side effects, neutral taste, or any discomfort in stomach after taking it. It works well as an antioxidant and for the immunity... I feel healthier overall and haven’t caught a cold in months. These vitamins should be taken every day forever. Totally satisfied.

24-Hour Vitamin C Protection
Verified purchase
Reacta C is another patented, buffered, slow-release vitamin C supplement besides Ester C that I'm recommending. Like Ester C, Reacta C is also gentle for the stomach (low acidity) and able to provide a 24-hour immune vitamin C protection. In addition to vitamin C, Solaray also added another potent antioxidant berry ingredient - elderberry - plus bioflavonoids for maximum bioavailability and effectiveness. Are you aware that our normal skin contains high concentrations of vitamin C, which supports an important function, ie stimulating the synthesis of collagen? NOTE: Do not crush, chew, or break the tablet. Swallow it whole.
