Shelf life is a big deal when you're picking a supplement format — for manufacturers and consumers alike. What you put in it, how you make it, and what shape it takes all affect how long it stays good. That's why gummies, capsules, and tablets don't all age the same.
What Drives Shelf Life?
Shelf life comes down to stability — how well a product keeps its identity, strength, quality, and purity over time. The big factors are:
- Moisture Content: Water activity drives degradation — a little moisture can wreck things.
- Ingredient Stability: Some vitamins and active compounds are sensitive to oxygen, light, or heat.
- Physical Format: How dense and sealed the delivery system is.
Gummies vs. Capsules vs. Tablets
Gummy Supplements
Gummies are a different beast. The gelatin or pectin base holds more moisture, so they're more vulnerable to heat and humidity. Well-made and properly packaged gummies last around 18 to 24 months. Over time, you might see changes in texture, color, or flavor if storage conditions aren't ideal.
Capsules (Softgels and Two-Piece)
Capsules — especially softgels — give great protection against oxygen and moisture for liquid or oil-based ingredients. Two-piece hard capsules do the same for powders. Stored right, capsules hold their potency for 24 to 36 months. The sealed package does the work.
Tablets
Tablets are just compressed powders. They have the lowest moisture of the three — which makes them very stable. They often last 24 to 36 months or more, because compression itself shields ingredients from air and light.
Making It Last
No matter the format, storage is key. To get the full shelf life: follow label instructions, keep the container closed, and use it by the best-by date.
