About this offer

The promotion discounts the lower-priced of two qualifying items by 50%. It runs across most GNC-brand vitamins, protein and wellness products and refreshes every few weeks.

Third-party brands are frequently excluded, and the discount is calculated on the lower-priced item, so pairing two similar-value products maximises the saving. My GNC Rewards points are earned on the post-discount total.

What the offer applies to

  • GNC-brand vitamins, protein and wellness products

What is excluded

  • Selected third-party brands
  • Clearance lines
  • Gift cards
