Short answer: when taking collagen, avoid skipping days, taking more than the stated serving, and expecting results in a week. Outside the supplement itself, the habits that break down collagen in the skin are too much sun, smoking, a high-sugar diet, heavy drinking and poor sleep. If you have a fish or seafood allergy, avoid marine collagen altogether.
Mistakes with the supplement itself
1. Taking it on and off
Collagen is used by the body gradually, so the routine matters more than any single dose. Most studies on hydrolyzed collagen ran for eight to twelve weeks of daily use. Missing days here and there, or stopping when a pack runs out, is the most common reason people see nothing.
2. Taking more than the serving
Two or three scoops do not work faster than one. Stick to the serving on the pack. If you take several supplements, check the total protein you are adding.
3. Judging it after a week
Skin cells turn over roughly every four weeks, so give a daily routine at least two to three months before deciding. A 70 g trial pack is useful for testing the flavour, not the result.
4. Mixing a flavoured collagen into coffee
Flavoured powders such as orange or blueberry are made to be drunk in plain water. For coffee, tea or smoothies, use an unflavoured collagen. How to take collagen covers mixing and timing.
5. Ignoring allergies and medication
Marine collagen comes from fish, so avoid it if you have a fish or seafood allergy. If you are pregnant, breastfeeding, on prescribed medication or managing a health condition, speak to your doctor before starting.
Habits that break down collagen
6. Too much sun

UV light damages collagen fibres in the skin and is the largest outside cause of visible skin ageing. Daily sunscreen and shade in the middle of the day do more for skin than any supplement.
7. Smoking

Smoking reduces blood flow to the skin and increases the damage done to collagen and elastin fibres. It is one of the clearest causes of early wrinkling.
8. A high-sugar diet

Sugar can bind to collagen fibres in a process called glycation, which makes them stiffer and less elastic over time. Cutting back on sweets and sugary drinks helps.
9. Heavy drinking

Regular heavy drinking dehydrates the skin and lowers the vitamin C and zinc the body uses to build collagen.
10. Short sleep

The body does much of its tissue repair during sleep. Most adults need seven to nine hours.
What to eat alongside collagen
The body needs vitamin C to build collagen, so fruit such as amla, guava, oranges and papaya is worth having daily. Enough protein overall, from dal, eggs, paneer, fish or meat, also matters, since collagen alone lacks some amino acids.
