Good product

Positive. If i forget to take them for a couple of mornings, I start to feel down, lethargic, low energy. I recently repeated my Dexa scan ( I have osteoporosis) and the numbers are improved! What can I ask more? Good diet, exercise and right supplements, make the difference. Thank you Naturelo!

Bone strength supplement

This supplement gives me all I need for my bones. I like that I can open the capsule and sprinkle on my cereal in the morning if I want to, or take direct with water.

great

I'm pretty happy regarding Naturelo. When I discovered to suffer of Osteoporosis 5 years ago, I tried different kind of supplements. None was working. Since I started to integrate with Naturelo Bone Strenght my numbers with DEXA scan started to change in better! At this point I can sincerely state that Naturelo works. It does not upset my stomach and i can absorb the nutrients easily. Thank you Naturelo!!

Excellent product

Surprisingly great. In the past i had problems to absorb minerals to cure my osteoporosis, with Naturelo i do not have these problems, and does not give me any other side effect like upset stomach, headache, skin reaction, as used to happen with other brands before. Also i checked recently my bone mineral level score ( Dexa) and it’s improving!

Excellent product

Brilliant experience. I broke my ankle very badly and it has healed well but I also feel good in myself and have noticed a difference with my quality of sleep, my skin and my eye lashes are longer than ever!

Build your routine around it

Every routine starts with one daily multivitamin made for you. Answer a few quick questions and we’ll suggest yours, with only the top-ups your day calls for.

?Your multivitamin
Bone Strength with Plant-Based CalciumYour top-up
Calcium from marine algae, with D3 and K2

Some habits are worth settling into slowly, like a morning walk or an early night, the kind that quietly add up as the years go by. Looking after your bones sits happily among them, and it's much nicer when it feels like part of the day and not a chore.

A bone-focused complex that brings ten nutrients together in one daily routine: calcium, magnesium, zinc, boron, silica, manganese, potassium, vitamin C, vitamin K2 and vitamin D3.

The calcium and magnesium come from marine algae, and across the day you get a generous 600mg of calcium and 200mg of magnesium. The vitamin D3 is drawn from lichen, which is what keeps the whole thing plant-based, and the vitamin K2 is there as MK-7. The vitamin C comes with acerola cherry, a small, bright red fruit that's naturally rich in it, and a little zinc, boron and silica round everything out.

It's vegan and gluten-free, with no unnecessary fillers getting in the way.

Take two capsules with breakfast and two with dinner. Splitting them like that spreads the calcium and magnesium through the day, which is far easier than taking it all in one go. If four capsules feels like a lot to swallow, you can open them and stir the powder into your food or a drink. It's a lovely choice for anyone who likes to give their bones a bit more thought as time goes on.

What it supports: Calcium, magnesium, vitamin D and vitamin K contribute to the maintenance of normal bones, and vitamin C contributes to normal collagen formation for the normal function of bones.

Questions

How do I take it?

Four capsules a day: two with breakfast and two with dinner. The amounts on the label are for all four capsules.

How much calcium does it give?

600 mg of calcium from marine algae per four capsules, with magnesium, vitamin D3, vitamin K2, zinc and vitamin C.

Can I open the capsule?

Yes. The label says you can open the capsules and add the powder to food or a drink.

Is it vegan?

Yes. It's plant-based, in a vegetarian capsule, and free from soya, gluten, dairy, eggs, fish, shellfish, peanuts and sesame.

Can I take it if I'm on blood thinners?

It contains vitamin K2, which can interact with some blood-thinning medicines. Speak to your doctor first.

Why is there a UK sticker on the bottle?

The bottle carries its original US label, so we add a UK sticker with the nutrition information in the UK format. Go by the UK sticker.

How do I read the best before date?

It's printed month first, US style. So 03/06/2028 means 6 March 2028.

Can I take it with my other supplements?

Usually, yes. Check the labels so you don't double up on the same nutrient, and never go over the stated dose. If you take medication, are pregnant or breastfeeding, or are under medical supervision, check with your GP or pharmacist first.

How long before I notice anything?

Everyone is different. A supplement tops up your diet day after day, so take it every day and give it a couple of months to settle into your routine.

When will it arrive?

Order before 2pm on a working day and we send it the same day. Standard UK delivery is free and takes 1 to 2 working days. Guernsey and Jersey take 2 to 5 working days.

How do returns work?

If it isn't right for you, send it back within 30 days of delivery, even if it's opened, and we'll refund you in full. Email support@naturelo.co.uk with your order number and we'll send you a free returns label. The guarantee covers your first order of each product.

How do I change or cancel my subscription?

Log in to your account to change the date or frequency, skip a delivery, pause or cancel. There's no need to call or email us. We'll also email you 3 days before each delivery, so nothing arrives by surprise.

Seems fine although time will tell.
I have been taking a similar product from Canada which is much more expensive,
They have the same ingredients so thought I would give Naturelo a try.

Essential nutrients for healthy bones

This is a great mix of essential nutrients to maintain healthy bones. The quality of Naturelo products are superb and it seems the company put a lot of thought into the ingredients. My partner takes 2 capsules in the morning and would notice the difference without them.

Exactly what I was looking for!

I choose these Calcium supplements as the dosage is high compared with others. Taking 2 AM plus 2 PM is perfect as your body can only absorb so much calcium at one time. Added positive is the other nutrients like K2 and zinc.

A+++++++++

Did a lot of research into calcium supplements and these stood out from the others. Great combination of nutrients and I feel as though my bones are getting fed. Also the amount of calcium in comparison to others is higher which is great.
