While I'm sure the product you've used will improve your calcium/vitamin D I don't think it should be your only strategy.
While the current UK RNI is 700mg there is good reason to think that may be a bit on the low side.
If we look at what they suggest in the USA
Dietary Supplement Fact Sheet:Calcium
You'll see they suggest much higher levels for older people and regard 700mg/daily as adequate for a 3 yr old.
We should be getting MOST of our calcium from food sources, cheese, milk, yoghurt and veggies and fish so it's only the difference between how much your diet is provided and a sensible RDA that you require. There are calcium calculators online that will help you work out how much calcium the other foods/drinks your consuming are contributing. There are reasons (increased stroke risk) why we shouldn't use more than 600mg daily calcium from supplements. The yoghurt base provides about half the calcium in Calin the rest comes from Calcium citrate so that would count as supplemental calcium.
The vitamin D content of Calin really isn't worth counting as it's virtually a placebo amount. Human DNA is set to produce 10,000iu given full body midday summer sun exposure and most UK adults require at least 5000iu daily.
If you look at your Calin you'll see it contains 5µg and your body really needs at least 125µg so as far as Vitamin D is concerned the amount inCalin is far too little to do anything to correct vitamin D deficiency.
Perhaps you could look at the label for me as their website doesn't give any information about the type of Vitamin D they use.
The plant form of Vitamin D is Vitamin D2 ERGOCALCIFEROL while the human form is Vitamin D3 CHOLECALCIFEROL. The chole bit tells you it's made from a form of cholesterol in your skin that changed when UVB rays (sun tanning lamps) hit it. Because the plant form isn't HUMAN the body tends to reject it so compared to Vit D3 the Vit D2 lasts a lot shorter time in the body and therefore because it speeds up vitamin D disposal it's less effective and much less potent.
The label may say Cholecalciferol D3 or Ergocalciferol D2 it would be nice to have it confirmed they are using D3 the human form.
