Understanding the Scent and Appearance of Metabiotics Resveratrol

Based on your description, the sour, musty, or strange smell and slightly cloudy appearance of your Metabiotics Resveratrol product are likely normal characteristics for ingredients derived from fermentation processes.

• Fermentation Process: Ingredients like metabiotics or ferments are produced by microbial fermentation. This process naturally creates various compounds, including organic acids and volatile substances, which can result in distinctive odors that might be perceived as sour, yeasty, or even slightly 'off' compared to non-fermented ingredients.
• Cloudiness: Depending on the specific formulation and the nature of the fermented extract or powder used, a slightly cloudy or hazy appearance can also be normal.

This is similar to how fermented foods or beverages have unique scents and appearances (like yogurt or fermented essences). The reply from cosmeceutical7 also aligns with this, noting that ferments can have a 'bood' (fermented/sour) smell.

When to Be Concerned:

While the described characteristics are often normal, you should check:

• Expiry Date: Ensure the product is within its recommended shelf life.
• Storage: Verify it has been stored according to the product's instructions (e.g., away from direct sunlight, at the correct temperature).

If the smell is extremely foul, significantly different from when you first opened it, or if you notice other signs of spoilage like mold growth or drastic changes in color or consistency, the product might be compromised.
