Temperature and Humidity Effects on Different Supplement Dosage Forms

Environmental conditions, especially temperature and humidity, play a critical role in maintaining the quality and stability of dietary supplements. For brands producing or sourcing supplements via OEM/ODM partners, understanding these effects across different dosage forms helps ensure product integrity, shelf life, and regulatory compliance.

This article explains how temperature and humidity impact softgels, hard capsules, tablets, powders, gummies, and liquids.

1. Softgel Capsules

Softgels are gelatin-based capsules containing liquids or semi-solids.

• Temperature effects: High temperatures can cause capsules to soften, stick together, or leak, while freezing may lead to cracking.

• Humidity effects: Excess moisture can make the gelatin sticky or deformed, whereas extremely low humidity can make them brittle.

• Manufacturing and storage considerations: Softgels require controlled temperature and humidity environments during production, packaging, and storage.

2. Hard Capsules

Hard capsules typically contain powdered or granulated ingredients.

• Temperature effects: Extreme heat can accelerate degradation of sensitive ingredients, while cold temperatures generally have minimal effect.

• Humidity effects: High humidity may cause capsules to swell, stick, or even dissolve prematurely, especially if gelatin-based.

• Best practices: Store in sealed containers in a dry environment; moisture-resistant coatings can improve stability.

3. Tablets

Compressed tablets are solid dosage forms, often coated.

• Temperature effects: Generally stable under moderate temperature, but heat can affect coatings, disintegration, or active ingredient stability.

• Humidity effects: Moisture can cause tablets to soften, stick, or degrade, potentially affecting dissolution or appearance.

• Protective measures: Coatings, blister packs, or desiccant inserts can improve moisture protection.

4. Powders

Powders are versatile dosage forms, including drink mixes and dry blends.

• Temperature effects: Heat may accelerate degradation of sensitive ingredients but generally does not affect physical structure.

• Humidity effects: High humidity can lead to caking, clumping, or microbial risk, affecting flowability and dosage uniformity.

• Mitigation strategies: Use moisture-proof packaging, desiccants, and controlled storage conditions.

5. Gummies

Gummies combine active ingredients with gelatin, pectin, or other gelling agents.

• Temperature effects: Heat can cause gummies to melt or stick together, while freezing may alter texture.

• Humidity effects: Excess moisture can make gummies sticky, whereas very low humidity can make them brittle.

• Storage recommendations: Maintain stable temperature and moderate humidity; use moisture-resistant packaging.

6. Liquid Supplements

Liquids include syrups, oil-based, and aqueous solutions.

• Temperature effects: High temperatures can affect viscosity, solubility, and ingredient stability. Freezing may lead to separation or container rupture.

• Humidity effects: Less directly impactful, but condensation can contaminate product if packaging is not airtight.

• Packaging considerations: Use sealed, light-protected containers and recommend appropriate storage conditions.

Key Takeaways for OEM/ODM Manufacturing

• Different dosage forms respond differently to environmental conditions; formulation, packaging, and storage must be optimized for each form.

• Softgels and gummies are most sensitive to temperature and humidity changes, requiring careful monitoring.

• Powders and tablets are generally more resilient but still benefit from moisture protection.

• Liquid supplements require temperature control and airtight, light-resistant packaging to maintain stability.

OEM and ODM partners can provide expertise in formulation, packaging, and storage strategies to minimize environmental risks and maintain product quality across all dosage forms.
