[Lewis Thomson (OP)]

Staci is curious about finding the answer to this question,

"How do I order hyaluronic acid supplements by the correct weight in MILLIGRAMS, when the suggestion it’s in terms of 130 kDa? I found a conversion table but it doesn’t relate to the choices I’m given on the bottles, such as 20mg or 100mg."

kDa refers to the molecular weight of the hyaluronic acid which is a polymer of sugar acids. It is an acronym for kilo-daltons. The actual amount in a certain dose is not connected with the mw of the substance.

Ask your doctor.
They may say it's a waste of money.

I was tempted to say it was a quack remedy but decided to stick to the op's question.
