I am looking for a Bovine Collagen product that is organic, grass fed,
which has 3rd party certification, GMP others. I started by writing
Gelita in Germany for names of sellers that use their Fortibone, Verisol etc.

There are 28 known types of Collagen. The well known are type 1 to 5
My focus is on helping my osteoporosis, which appears to be Type 1 and Type 3 Collagen
There are other types with claims for skin improvement, cartilage, osteoarthritis and so on.

My research list now includes brand names that are not on the initial list from Gelita,
but have similar qualities.
Collagen is a form of protein, and the amino acids are listed on the label of product.
There are more amino acids listed than the regular 8 we need to obtain from foods.
I probably will need to look them up.
Hydrolized means something similar to Peptides, a process which makes it easier to digest.

I don’t think I would buy AlgaeCal and others – because I can add my own Calcium,
Magnesium or other Vitamins and have control of amounts I take. Including Vitamin K

There is ConsumerLab which appears to be trustworthy, that is a resource which may
answer some of my questions. Perhaps an email to Dr Cooperman is possible.

I prefer not to take any supplements, especially as important as Collagen, without due diligence.
The only supplement I have bought is an Omega 3 supplement, but will wait to speak with a
dietitian on how best to integrate into my diet. (I have salmon once a week, occasionally sardines)

I want to ask the dietitian - are we well informed - only 500 mg calcium can be absorbed
at any meal. Is that from diet or supplements.
Another question: what about malabsorption as we get older, how do we know how
much our bodies are extracting.

I try to get calcium from regular foods - but need to limit dairy -
(there are many supplements, calcium gluconate, lactate, ascorbate, sulfate and more.)
I just realized that calcium carbonate is added to many drinks, like soy milk, oatmeal milk..
even Horlick’s which tastes like Ovaltine (am not sure if Ovaltine has calcium carbonate)
However, calcium carbonate, to some, is constipating.

My question here –
How does a consumer break down the amount per scoop: let’s say 10 grams,
between Type 1 and Type 2. is it mixed evenly…Do I get it balanced if I shake up the container.
I can, and eventually will call the manufacturer. But a second opinion is valued.
If someone has done some research on this, I would appreciate your time and knowledge.
