Full dose per serving on the label

Bone combines vitamin D3 and vitamin K2 (as MK-7) in one drop of oil a day: 25 µg of vitamin D3 (1,000 IU) and 20 µg of vitamin K2.

What the nutrients do
Vitamin D and vitamin K contribute to the maintenance of normal bones.
Vitamin D contributes to normal absorption and utilisation of calcium and to the maintenance of normal muscle function.
Vitamin D contributes to the normal function of the immune system.

How to use it
Take 1 drop a day, preferably with a meal. Vitamin D is fat-soluble, so taking it with food makes sense.

One 50 ml bottle holds 1,000 drops.

With Daily
Daily also contains 5 µg of vitamin D. If you take both, you get 30 µg of vitamin D a day.

Why Maeni

Made for women 45+, not for everyone

Most supplements are made for every adult. Maeni chooses each product for what changes in perimenopause, menopause and the years after, and shows every amount before you buy.

Topic Maeni Most supplements
Who it is for Women in perimenopause, menopause and the years after Every adult: the same jar at 30 and at 65
Why these nutrients Each product follows a need of this stage: extra vitamin D from 50, bones and muscle strength, tiredness, hormonal activity (vitamin B6) One broad formula, not chosen for a life stage
What else you get Guides on menopause, a symptom diary and strength training at home Product information only
Your routine A fixed morning and evening routine, with how many days each jar lasts Separate jars; you work out the combination yourself
Amounts Every amount per daily dose on the page, no blends Often only on the jar, sometimes hidden in a blend
Health claims Only EU-authorised claims, at the dose they are based on Not always backed by the dose in the jar
Your first months

What to expect

  1. Day 1

    Pick a fixed moment in your day (best moment: with a meal) and keep the jar where you will see it: next to the kettle, your coffee or your toothbrush.

  2. The first weeks

    Take it every day. The amounts on the label, and the EU claims, are based on daily intake, so taking it every day matters more than the exact time.

  3. When the jar runs low

    How long a jar lasts is shown at the top of this page. Reorder in time so you do not miss days, and add a second product to save with the mix-and-match discount.

Why D3 and K2 together

Vitamin D contributes to normal absorption and utilisation of calcium. Vitamin K and vitamin D both contribute to the maintenance of normal bones. In the Netherlands, women over 50 are advised to take extra vitamin D. Bone gives you D3 and K2 together in one drop a day.

Before you start

Good to know

If you use blood-thinning medication, consult your doctor before use: vitamin K affects blood clotting. Not suitable for pregnant or breastfeeding women, children or adolescents. If you take other supplements with vitamin D, check the total with your doctor or pharmacist.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the recommended daily intake. Keep out of reach of young children. Store closed, dry, cool and away from light.

Questions

How do I take it?

The dose and the best moment are listed next to the Add to bag button and on the label further down this page. Do not take more than the recommended daily amount.

Can I combine it with your other products?

Yes. Daily, Bone and Evening work as one routine: Daily gives you 5 µg of vitamin D and Bone adds 25 µg, 30 µg a day in total, so do not add another vitamin D supplement unless your doctor advises it. Daily contains vitamin A and iron, so do not combine it with other supplements that contain vitamin A or iron. The quiz suggests a combination based on your answers.

Is it suitable for vegetarians or vegans?

Evening uses vegan capsules and Strong is pure creatine monohydrate. Daily, Omega and Omega Max come in capsules made with bovine gelatine, and Collagen contains bovine collagen, so those four are not vegetarian. For Bone, see the full ingredient list on its product page.

Where is it made?

All our supplements are made in the EU.

Do you save when buying more?

Yes. Mix and match any of our supplements: buy 2 and save 10%, buy 3 or more and save 15%. The discount is taken off automatically in your bag.

Can I return an opened jar?

You can return unopened products within 14 days of receiving them. For health and hygiene reasons we cannot take back jars once the seal is broken. See shipping and returns.
