Supplement Storage

Does supplement storage matter?

Yes. Heat, humidity, and direct sunlight can degrade nutrients over time. Proper storage maintains potency through the product's shelf life. The good news: storage requirements for most supplements are simple and easy to meet in a typical home.

The three enemies of supplement stability

1. Heat

High temperatures accelerate chemical degradation. Most supplements are tested for stability at room temperature (15-25°C). Storing supplements in a hot car, on a sunny windowsill, or near a radiator can reduce potency well before the expiry date.

2. Humidity

Moisture is the biggest threat to capsule integrity. HPMC vegetable capsules (used by Nutri-Leaf) are more moisture-resistant than gelatin but still degrade in humid environments. Bathroom cabinets — despite being common storage places — are poor choices due to shower steam.

3. Light

UV light degrades many vitamins, particularly vitamin B2 (riboflavin), vitamin C, and vitamin A. Opaque or amber packaging (used by Nutri-Leaf) provides protection, but only if the container stays closed between uses.

Best storage practices

• Cool, dry place: A kitchen cupboard away from the cooker, or a bedroom drawer. Not the bathroom.
• Original container: Keep supplements in their original packaging with the lid tightly closed. The container is designed to protect the product.
• Out of direct sunlight: Any cupboard or drawer works. No windowsills.
• Out of reach of children: Essential safety practice. Supplements can look appealing to children.
• Don't refrigerate unless specified: Most supplements are formulated for room temperature. Refrigeration can introduce condensation.
