Participants in the Activia Challenge must consume two servings of Activia yogurt per day for four weeks. At the end of the challenge, if the participant does not experience improved digestive function, he may request a refund for the full cost of the yogurt, or up to $65.
The Activia challenge outlined on Activia.US.com is open until October 31st, 2015. The participant must complete his purchase by this date for refund eligibility. The Activia challenge is open to all residents of the United States, including the District of Columbia and Puerto Rico. The challenge is aimed specifically at individuals who experience occasional digestive issues such as bloating, gas, and rumbling.
Participants of the challenge must purchase enough Activia yogurt to last for the 28-day challenge duration. The contest guidelines state that participants should eat two servings of yogurt per day, for a total of 56 servings. Participants are encouraged to purchase yogurt packaged in individual serving cups or drinks. Any flavor of Activia yogurt may be eaten during the challenge.
If the participant does not see improvement in his digestive function as a result of eating Activia yogurt, he may fill out the redemption form available on the Activia website and mail it to the company with his original purchase receipts and a brief description of why the product was ineffective.
