In your opinion, do citrus fruits and tomotoes inhibit calcium intake.

I had heard it may from a book that was copyright in 2006. I did not know what the latest information was.

I have osteoporosis and was drinking pure lemon juice as a cleanser.

Any information will be helpful on that.

Thanks in advance.

Citrus fruits are acidic but not acid forming; actually they are alkaline forming, and you can take them. It's oxalic acid that inhibits calcium (spinach, rhubarb, others).
Calcium needs many nutrients to be absorbed into the bones rather than forming deposits in soft tissue, including vitamins C (from supplements, some vegetables, or juices) and D and magnesium. Exercise is also vital, which seems to be rarely mentioned these days. Calcium is one of most difficult to get right.
It is actually difficult to measure calcium absorption, so all the brands claim their's is best. And to add to the confusion, it isn't clear that absorption is more important than bone-forming ability, another measurement entirely.

There is controversy over the best sources of calcium (seashells, eggshells, bone) and what form tabs are made in - carbonate and citrate are the two most common; there's also malate, orotate.

Here is a quote from Dr. Andrew Weil, a person respected for both solid medical and science training as well as health alternatives:

'I see no advantage in taking calcium orotate instead of calcium citrate unless you just want to spend more money for your supplement. The most common and least expensive type of supplemental calcium available is calcium carbonate. Although the citrate form is a bit more expensive, it is more easily absorbed, especially by older people who may have less stomach acid. And it is more than twice as bioavailable as calcium carbonate.
For bone health, I recommend that all women supplement with 500 to 700 mg of calcium citrate in two divided doses taken with meals, for a total daily calcium intake of 1,000-1,200 mg from all sources. For men, I now suggest aiming for 500 mg from all sources. (Because higher amounts have been linked to increased risks of prostate cancer, men generally should avoid supplemental calcium.) You can also get calcium by eating leafy greens and soy foods, as well as milk and milk products. However, it appears that vitamin D may be more important to bone health than calcium.
I recommend that both men and women take 2,000 IU of supplemental vitamin D3 to facilitate calcium absorption and promote bone mineralization - as well as for protection from many forms of cancer and other serious diseases.'
