There is no single collagen serving that is ideal for every person and every goal. Compare the declared daily amount in the complete formula and follow the product directions. The scoop weight, number of capsules and collagen weight can be different.
Grams and milligrams
One gram is 1,000 milligrams. A label declaring 10,000 mg of collagen is describing 10 g. Confusing milligrams with grams can create a thousand-fold error, so keep units consistent when comparing products.
A scoop is a measure, not the ingredient total
Powders can include flavouring, acids or other ingredients as well as collagen. Capsules also contain their shell and may combine several ingredients. Use the amount of collagen actually declared per recommended daily serving.
What a study dose can tell you
Trials use specific preparations and doses for particular outcomes. A studied amount is not a universal prescription, and a dose range cannot be transferred to a different collagen type or formula without context.
Combining products
If you use a liquid and a powder, add their daily amounts and any duplicated nutrients. Taking both is not automatically more useful. Do not exceed the directions simply to imitate a different study or chase a faster result.
When individual advice matters
Allergens, pregnancy, breastfeeding, medicines and health conditions can affect suitability. Side effects are possible; high purity does not justify a promise of no side effects. If any of those factors are relevant, discuss the complete label with a healthcare professional.
Compare on a consistent basis
Look at source, collagen amount, serving count and current price per serving. Our collagen collection and ingredient guide help you compare the current formulas without an invented ideal dose.
