Adcal-D3 Caplets

[Harrywogan]

Hi all,been on Adcal-D3 for 6years,2 in afternoon and 2 at bed time, just wondering how long you have to take them, 🤔 was worrying about kidney stones don't want them,seems it's the vit d that can cause them,but if they helping the bones . Xx

I kept getting cystitis symptoms and my doctor advised me to give Adcal up. I now take vit D3 on prescription and have a calcium rich diet. My DEXA Scans have shown a slight decrease in bone density over a 7 year period but I have been much less active.

Thanks Jane, hate the thought of kidney stones think that's wot bothering me had no problems with them but after reading about it in magazines it's been niggling me,think I'll cut to 2 a day for a while as you can't tell IAM a worrier lol xx

is a readable article that dispels the myths in the magazines. It was suggested that since vit D improves absorption of calcium it might cause kidney stones - it might in rare cases but it has been shown there isn;t an increased risk.

I and a few others have had problems with calcium causing grit to form in the urine and in the gall bladder so I switched to good dietary calcium and separate vit D - and I take 4000 IU a day.

In fact, your body will only absorb 500mg of calcium at a time, you get rid of the rest so you are better on just 1 caplet at a time and take some extra vit D because 400 IU a days isn't really enough.

Hi there,I've stopped taking calcium and Vit.D3 combined and just eat a calcium rich diet and take 3000 IU of Vit.D3 daily. No issues so far and calcium levels remain good.

you need to take D3 with Vitamin K2 for best absorption

[PMRpro Ambassador in reply to Eric48]

No, you need to take D3 with calcium for best absorption of calcium from the gut. K2 has a different role - it directs the calcium to the bones rather than the arteries.

The article I have linked to actually says the diet in Western Europe contains K2 because of cheese and dairy.

"We examine how undercarboxylated osteocalcin (ucOC) and matrix Gla protein (ucMGP) are converted to carboxylated forms (cOC and cMGP respectively) by K2-7 acting as a cofactor, thus facilitating the deposition of calcium in bones and preventing vascular calcification. K2-7 is beneficial in managing bone loss because it upregulates osteoprotegerin which is a decoy receptor for RANK ligand (RANKL) thus inhibiting bone resorption"

Any other insistence of need for K2 comes from websites selling K2. I do see a connection there ...

Thank you. An interesting ( and complicated !) read, however I think I will continue to take D3 and K2 and get my Calcium from my diet

I gave up calcium some years ago - cheese is a great calcium and K2 source, Can't take K2 supplements - on anticoagulants and K2 has some effect though not as much as K1

There is no mention of magnesium, which is essential to utilize the calcium from the blood to build bone instead of being deposited in the wrong places. Common dosage is 200-250 mg twice a day (oxide form is not absorbed).
