Why are softgels in non-clear bottles?

When I buy my softgels, they typically don’t come in clear bottles but colored or opaque ones. I definitely dislike not being able to see inside the bottle but I know there is a reason for this packaging choice. Let’s find out what they might be!

1. Light and Heat Sensitivity:

One of the primary reasons for choosing opaque or colored bottles for softgels lies in their sensitivity to light and heat. Softgel capsules often contain sensitive ingredients, such as vitamins, oils, or botanical extracts, which can degrade when exposed to light or elevated temperatures. The opaque or colored bottles act as protective shields, reducing the potential damage caused by these external factors.

2. Oxidation and Stability:

Many softgel formulations contain oils or other ingredients prone to oxidation. Exposure to light and air accelerates this process, leading to the degradation of the product’s quality and effectiveness. By using opaque or colored bottles, manufacturers can minimize the entry of light and oxygen, preserving the stability and potency of the softgel contents. This ensures that the product retains its desired properties throughout its shelf life.

3. UV Protection:

Ultraviolet (UV) radiation is known to cause photodegradation in various substances, including pharmaceuticals and supplements. Softgel capsules can be particularly vulnerable to UV radiation due to their gelatin-based shell. The dark or colored bottles provide an extra layer of UV protection, shielding the delicate contents from the harmful effects of sunlight and artificial light sources.

4. Moisture Control:

Another crucial factor to consider when packaging softgels is moisture control. Clear bottles offer minimal protection against moisture, which can lead to softgel shell deterioration and the potential for microbial growth. Opaque or colored bottles, on the other hand, create a more controlled environment, reducing the risk of moisture-related issues and maintaining the integrity of the softgel capsules.

5. Extended Shelf Life:

By employing opaque or colored bottles, manufacturers can extend the shelf life of softgels. The protection provided against light, heat, oxidation, UV radiation, and moisture helps maintain the product’s quality and effectiveness for a more extended period. Typically, a company might do stability testing in accelerated conditions of 40C and 75% Relative Humidity to address the above points and to set shelf life of the product. This is especially crucial for supplements and medications that may be stored for months or even years before consumption.

Though you may not be able to see inside the bottle, you can now appreciate the thoughtfulness behind their protective packaging choices.

Stay well!
