Red Bird’s Nest Drink - Is it really healthy?

Also known as Red Bird’s Nest Drink, I recently got some from family, who bought it from Costco. It's by Golden Nest and claims to have 100% genuine swallow Red Bird’s Nest. I tried a pre-chilled bottle and it tasted fine with some soft chunks of what I assumed to be the actual Red Bird’s Nest. Regarding the drink itself, I felt it was a bit sweet, and there is 14 grams of sugar.

I've heard a lot about Red Bird’s Nest drinks, especially the supposed health benefits. But I've never really done my own research, so here's everything that I've read and learned so far:

What is it?

• It's the saliva of the nest of the swiflets.
• Male swiftlets build the nest with the saliva, which forms a type of salivary glue (imagine a cement) for their nest.
• Different varieties and grades of Red Bird’s Nest are available.
• Harvested Red Bird’s Nest can be cooked into a soup or drink.
Harvesting and Cleaning Process:
• Traditionally harvested in limestone caves by climbing up tall ladders... quite dangerous!
• Cleaned by removing twigs and feathers that are also part of the Red Bird’s Nest.
• The popularity has created "farms" of concrete builds designed to breed and harvest Red Bird’s Nest.
• Popularity has attracted counterfeits: even China has banned some imports of Red Bird’s Nest.
• Cleaning fresh Red Bird’s Nest is best done with cold water, as opposed chemicals that deplete nutritional value.
• Not considered (by me) to be unethical to swallow because it's harvested after the bird's leave and abandon the nest.
