The shelflife of the Testa capsules is at least 2 years if stored at temperatures between 15 - 25 °C. Other manufacturers usually have 3 years of shelf life, but Testa uses the strictest safety standards.
This combined with multiple production runs each year, Testa uses an air-tight blister package to ensure the best possible freshness of the capsules. We also add more vitamin E than other algae oil producers.
Vitamin E is known to prevent oxidation. You can find the expiration date (month + year) on the back of the blister next to the batchnumber.
