Vitamin C

Acerola cherry is naturally rich in Vitamin C, a nutrient that’s especially sensitive to heat, light, and oxygen. Freeze-drying allows us to preserve Vitamin C by gently removing moisture at low temperatures, rather than relying on heat-based drying methods that can degrade delicate nutrients.

FRTIL Vitamin C is a whole-food form sourced from 100% organic acerola cherry, rather than a synthetic isolate. Synthetic vitamin C is isolated ascorbic acid, while whole-food vitamin C comes packaged with naturally occurring cofactors such as bioflavonoids and enzymes found in the original plant.

We choose whole-food vitamin C from acerola cherry not only because it naturally contains a high amount of ascorbic acid, but also because it provides a broader spectrum of supportive phytonutrients, including phenolics, flavonoids, anthocyanins, and carotenoids.

Many synthetic Vitamin C supplements on the market provide 500 to 1,000mg per serving. These high doses can increase the risk of overconsumption and, in some individuals, have been associated with elevated urinary oxalate levels.

More importantly, research shows that when single doses of vitamin C exceed approximately 500mg, absorption efficiency decreases and excess vitamin C is simply excreted in the urine, offering no additional benefit. Vitamin C is best supported through smaller, consistent—or even frequent—amounts rather than large, isolated doses.

No. Our formula contains Vitamin C exclusively from organic acerola cherry, with no added synthetic ascorbic acid. Because we work with the whole fruit, vitamin C content may naturally vary from batch to batch based on factors like seasonality and growing conditions.

As a result, vitamin C levels per serving may fluctuate slightly, and we reflect these changes transparently on the most up-to-date product label.

Acerola cherry is one of the most Vitamin C rich foods in the world. FRTIL Vitamin C is made from 100% freeze-dried organic acerola cherry, with no additives or synthetic ascorbic acid.

Our Vitamin C is sourced from 100% organic acerola cherry, a whole food ingredient. Because we use the whole fruit rather than synthetic isolates, natural variation is expected. 

Factors such as growing conditions, weather, and harvest timing all influence the final nutrient content. As a result, the amount of vitamin C per serving, as well as differences in color, taste, or capsule size, may vary slightly from batch to batch. Unlike synthetic ascorbic acid, which can be standardized to exact amounts, whole-food nutrients exist within a natural range.

We believe in reflecting this honestly. Each batch is tested, and our labels are updated accordingly so you know exactly what you are receiving in each serving. While variation is part of working with whole foods, our standard remains consistent.

We will always provide a meaningful dose of vitamin C, equivalent to or above 300mg per serving, using only 100% organic acerola cherry, with no synthetic ascorbic acid added to standardize potency.

Yes. The acerola cherry in our Vitamin C is certified organic and sourced from growers who adhere to USDA NOP standards.
