What is the Double Box?

Two boxes of Key Collagen in every order, at a lower price per box than buying them separately.

Each box is 30 sachets, a full month for one person. So one order covers two people, every month, without either of you having to remember to reorder.

Who is it for?

For you and one other person. Your mother, your sister, your other half who has quietly worked out it is good for joints. One order, two routines.

For a partner who keeps helping themselves. Collagen decline is not a women’s issue, and plenty of our customers are men taking it for their joints. Two boxes means he can have his own instead of raiding yours.

New to Key Collagen? Collagen works on consistency, and most people who give up do so around week six, right before it gets interesting. Starting alongside someone else makes month three a lot more likely.

BENEFITS

Each box supports:

  • Joint comfort and mobility
  • Bone support
  • Healthy hair and nails
  • Skin hydration and elasticity
  • 2,500mg VERISOL® per daily sachet
HOW TO USE
STEP 1 Anytime: Take one sachet a day, straight from the sachet. Nothing to stir, measure or wash up.
STEP 2 The second box: Hand it over, or keep it for next month.
STEP 3 Continue for at least 3 months for best results.

Why two boxes?

One for you, one for them.

It is the question we hear most from customers. Their mother’s knees, their sister a few years behind them, the partner who started helping himself to the sachets. Two boxes a month means you can just hand one over instead of explaining where to buy it.

It is easier to stick with when someone else is doing it too.

Collagen rewards consistency, and having someone to compare notes with makes month three a lot more likely than going it alone.

One month is not a fair trial.

The research on this dose shows changes at four weeks and eight weeks. A single box takes you to the first and stops.

It costs less per box.

Same product, same daily sachet, better price than ordering one at a time.

What is in each box

One daily sachet, two full boxes in every order. A 30-day supply per person, or two months for one.

FREQUENTLY ASKED QUESTIONS

SEE ALL
Is this two boxes every month?

Yes. Every delivery contains two full 30-day supplies, so you and one other person are each covered for the month.

Should I take two sachets a day?

No. One sachet a day is the daily dose, whether you have one box or two. The second box is for a second person.

Is Key Collagen suitable for men?

Yes. Collagen decline is not a women’s issue, and plenty of our customers are men taking it for their joints. We hear about it most from women whose partners started helping themselves to the sachets and then asked for their own box.

Can I share it with someone else?

Yes, and plenty of customers do. Each box is a full 30-day supply on its own, so two people can take it at the same time.

I have never tried Key Collagen. Should I start with two?

Two boxes gives it a fairer go, since the results in the research show up at four and eight weeks and a single box runs out in between. If you would rather test the water first, a single box is right there and we will not talk you out of it.
