Both these were just questions off the top of my head … This one maybe because my own ‘original vision’ of anything ‘liposomal’ with ECDY involved lowest possible ratios of solvents (water, in this case ) to the ECDY… Basically, I think I would prefer to end up with more extra phospholipids extant in the product than having extra ECDY floating around. But, then again, you may have nailed your recipe where a consistent product is concerned.aron7awol wrote: ...I'm also curious why you may suggest lowering the water ratio in the recipe? ...
and re:
I hear dat. Health first... still, any questions about non phosphatidylcholine emulse are related to my concerns in posts up at the top of the thread about inhancing delivery precision.aron7awol wrote: ...I went with sunflower lecithin over Polysorbate only due to thinking it was more natural and therefore better, but I readily admit I have no reason to think that sunflower lecithin would be an equal/better carrier than Polysorbate in this case.

Liposomes are biphasic, a feature that renders them the ability to act as carriers for both lipophilic and hydrophilic drugs. It has been observed that drug molecules are located differently in the liposomal environment and depending upon their solubility and partitioning characteristics, they exhibit different entrapment and release properties [15, 16]. Lipophilic drugs are generally entrapped almost completely in the lipid bilayers of liposomes and since they are poorly water soluble, problems like loss of an entrapped drug on storage are rarely encountered. Hydrophilic drugs may either be entrapped inside the aqueous cores of liposomes or be located in the external water phase. Noteworthy is that the encapsulation percentage of hydrophilic drugs by liposomes depends on the bilayer composition and preparation procedure of the liposomes [17, 18].

ie the recipe for liposomal Vit C may be good/acceptable for ECDY, but I just can’t imagine it being optimal for ECDY.
I’m not sure ‘they’ even know how the agents in a liposome are actually released yet. Processed in the liver as fats and released? Or cells, hungry for phospholipid materials, tear off a part of the ‘sphere’ which releases the contents? Or both ? https://www.livonlabs.com/cgi-bin/start. ... ation.html
What do ya’ll think? Do you ‘believe’ liposomals are primarily broken open to release their payload in the liver or that processes all over the body break them open for their phospholipids? Or both/either, depending on the 'hardiness' of the 'sphere'?
Follow up questions ----with ECDY, are we looking for ‘stronger’ or ‘weaker’ (like polysorbates ??) liposomals where payload could be released near/in cells?
…From here, my mind quickly turns to double bags, integrins, and intercellular tensegrity … and ya’ll are probably wishing curious george would just shut the fk up...View more Emoticons
