Still trying to nail down an optimum supplement regime (bone health my first priority as I have mild, early-onset osteoporosis) and I realise I've never really questioned taking FCLO and sometimes high-vitamin butter oil too. Coming to paleo/primal via WAPF where all the Green Pastures products are unquestioningly recommended I wonder are they necessary, just a source of A and D and a little omega 3 (K2 and anti-arthritic Wultzen factor in the case of butter oil) or do they have some magical synergistic properties that cannot be found elsewhere?
I also worry slightly about the rancidity of the oils (I have a feeling Paul Jaminet does not recommend fish oils at all) as it's impossible to judge from a taste point of view as they taste so ghastly anyway. I've tried fermented skate oil in the past, which seemed to have a better A/D balance, not so heavy on A, but didn't notice any difference. Cod liver oil seems to be promoted for immunity but is this just as a result of the A/D etc they contain?
Wondered what opinions were on these products, I don't like buying from any company that has such a monopoly in a marketplace but people I respect such as Chris Kresser, Chris Masterjohn and Stephan Guyenet all seem to take or recommend these oils.
I forgot where I read it recently, but Weston Price found that every culture had its own superfood, and that this animal food was always high in Vitamins A and D. Thus, we have grass fed butter, fish eggs (roe), liver, and cod liver oil.
Personally, I feel better when taking the FCLO. It took me a while to get over the "monopoly" and to make sure it wasn't just a conspiracy, but I bought some, and feel better.
They are quick to point out that it's not just the vitamin A or D, or the EPA or DHA or everything. Each dose has a wide range of different types of A and D. Taking them in food form keeps the synergy there.
