Product Description
Product Description
Vitamin C is a powerful antioxidant that supports immune health, nerves, eye health, collagen production, and blood vessels. Research shows that vitamin C neutralises free radicals and facilitates the body's ability to absorb iron from foods and supplements. Desert Harvest Buffered Vitamin C is bladder-friendly and gentle on the stomach.
All Desert Harvest supplements are gluten-free, bladder-friendly, and contain no fillers or artificial ingredients. We follow strict Good Manufacturing Practices and are cGMP compliant.
Ingredients: Each serving (1 capsule) contains 400 mg of Vitamin C (calcium ascorbate) buffered with 40 mg of calcium carbonate, 75 mg of Organic Aloe Vera (Leaf and Inner Gel) - which has been shown in studies to enhance the absorption of nutrients, and trace amounts of silicon dioxide (a naturally occurring mineral) as a drying agent.
Directions: As a food supplement, take one capsule twice a day or as directed by a qualified healthcare professional.
Food supplement. Do not exceed the recommended daily dose. Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. Consult a healthcare professional if pregnant, breastfeeding, or taking medication.

Buffered, non-acidic form
Vitamin C as calcium ascorbate — a buffered, pH-neutral form — rather than acidic ascorbic acid. A gentler choice for sensitive systems.
Everyday immune support
Vitamin C contributes to the normal function of the immune system and to the protection of cells from oxidative stress — authorised EU claims. 400 mg per capsule.
An easy daily habit
90 vegan capsules with a little inner-leaf aloe vera. One capsule, up to twice a day, as part of a calm routine.
Why buffered
Vitamin C in a gentler, buffered form
Standard vitamin C is ascorbic acid, which is naturally acidic. This food supplement uses calcium ascorbate instead — a buffered, pH-neutral mineral form that delivers the same vitamin C, more gently.
Vitamin C contributes to the normal function of the immune system, to normal collagen formation, and to the protection of cells from oxidative stress — these are authorised EU claims. It also increases iron absorption from food.
The buffered form makes it a popular choice for people following a gentle, bladder-friendly or sensitive-stomach routine. We describe the composition plainly and let you decide where it fits.
