The short answer. The biggest collagen myths are that it works overnight, that all collagen is the same, and that a big milligram number alone means quality. The facts: results are gradual, form and source matter, and absorption depends on the collagen being hydrolysed.
Myth: collagen works instantly
Fact. Collagen is cumulative. Most women notice gradual changes between weeks 6 and 12 of daily use. See how long collagen takes to work.
Myth: all collagen is the same
Fact. Source and form matter. Marine collagen is rich in Type 1, and only hydrolysed collagen absorbs well.
Myth: a big milligram number means quality
Fact. A high dose only helps if it is hydrolysed so your body can use it. Strength plus absorption together are what matter.
Myth: collagen is only for older women
Fact. Collagen declines from the mid 20s, so many women start earlier as a habit. See when to start.

Frequently asked questions
Does collagen really work or is it a myth?
Research suggests hydrolysed collagen may support skin and joints when taken daily. It is not instant, and quality and consistency decide the result.
Is all collagen the same?
No. Source and form matter. Marine collagen is rich in Type 1, and only hydrolysed collagen absorbs well.
Does a higher milligram mean better collagen?
Only if it is hydrolysed so your body can absorb it. Strength and absorption together are what count.
Is collagen only for older women?
No. Collagen declines from the mid 20s, so many women start earlier as a preventative habit.
