What Olive Oil/Soya Oil/Egg Lecithin-Based Emulsion is, and what it does.
- Does it work
- Hospital product. If you're researching for TPN, consult your medical team.
- How much to take
- A clinician sets and infuses this. The fat load commonly sits around 5 to 15g a day, matched to body weight and bloodwork rather than chosen at home.
- Time to feel it
- It goes straight into a vein, so the fatty acids reach the circulation within hours. What changes is read from nutrition bloodwork over days.
- The first dose
- On day one the droplets are cleared by lipoprotein lipase as they arrive, so the team watches infusion rate and blood triglycerides closely.
- With regular use
- Over weeks it keeps linoleic and alpha-linolenic acid arriving, plus phospholipid and choline from the egg lecithin, when eating normally is not possible.
- How well tolerated
- Given only under medical supervision through a vein. It carries egg and soya derived material, and infusion rate is capped by how fast lipase clears it.
- How it feels
- There is nothing to taste or swallow. Anything noticeable during an infusion is something to tell the team about rather than sit with.
- The overlooked benefit
- The egg lecithin holding the droplets apart is mostly phosphatidylcholine, so the emulsifier itself supplies choline and phospholipid, not just structure.
5 to 15g a day is where Olive Oil/Soya Oil/Egg Lecithin-Based Emulsion works.

Questions people ask about Olive Oil/Soya Oil/Egg Lecithin-Based Emulsion.
- When should I take it?
- Timing matters less than consistency. Pick a time that works for you and take it daily.
- Can I take it with other supplements?
- Usually fine. The main thing to watch is not doubling up on the same ingredient from different products. If you're on prescription meds, check with your pharmacist first.
- Any side effects to watch for?
- Most people tolerate it well at recommended doses. GI upset is the most common complaint with any supplement. Start with a lower dose and work up. If something feels off, stop and reassess.
Why these belong in the same formula. Each row says what the basis is, from settled biochemistry through to a trial that measured the pair.
Egg lecithin supplies the phospholipids that coat each oil droplet and keep the oil phase dispersed in water. Without it the olive and soya oils would separate immediately. The lecithin is not an added extra here; it is a structural component of the emulsion itself.
Egg-derived lecithin is high in phosphatidylcholine, which forms the monolayer at the droplet surface. That same molecule is the body's main phospholipid building block and a choline-bearing compound. So the emulsifier is simultaneously a structural agent and a source of a nutrient.
Every phosphatidylcholine molecule in the lecithin carries choline as its head group, released by phospholipases during digestion. An emulsion built on egg lecithin therefore contributes choline alongside its fat. The amount tracks the phospholipid load, not the oil load.
Soya oil is roughly half linoleic acid, the essential omega-6 fatty acid, with a smaller share of alpha-linolenic acid. That composition is the reason soya oil is included in a mixed emulsion rather than using olive oil alone. Olive oil, by contrast, is dominated by monounsaturated oleic acid and carries much less linoleate.
The polyunsaturated fraction of soya oil oxidises at its double bonds, and alpha-tocopherol is the chain-breaking antioxidant that intercepts the resulting peroxyl radicals. Vegetable oils carry native tocopherols and emulsions are often supplemented with more. A higher polyunsaturated load raises the tocopherol requirement of the system.
Phylloquinone occurs naturally in soya oil at appreciable levels, so any soya-oil-based emulsion carries vitamin K1 whether or not it is declared. Olive oil contains much less. Anyone tracking vitamin K intake closely needs to know which oils a preparation uses.
Cholecalciferol is strongly lipophilic and dissolves in the triglyceride core of the emulsion droplet. That gives a dispersible vehicle for a vitamin that otherwise needs a fat meal. The emulsion acts as the carrier; it does not alter the vitamin's own metabolism.
Retinol and its esters partition into the triglyceride core and are shielded there from the aqueous phase. Oxidation remains the main stability problem, which is why tocopherol usually accompanies them. The emulsion is a delivery vehicle.
Xanthophylls such as lutein require a lipid phase and bile-derived micelles for uptake, so their appearance in blood tracks the fat consumed with them. An oil-in-water emulsion supplies both the lipid and the pre-dispersed droplet size. This is the same reason carotenoid absorption from a raw vegetable rises when oil is added.
Coenzyme Q10 is dissolution-limited and disperses only in a fat phase. The triglyceride core of an olive and soya oil emulsion provides that phase in an already emulsified state. The formulation addresses delivery only.
Emulsions are formulated with different oil blends, and adding a marine oil shifts the fatty acid profile toward long-chain omega-3 at the expense of the omega-6 share. That also raises the number of oxidisable double bonds in the system, which increases the antioxidant requirement. The pairing is a composition decision with consequences on both sides.
Medium-chain triglycerides are cleared from the bloodstream faster than long-chain triglycerides and do not depend on carnitine-mediated transport for oxidation. Blending them with long-chain vegetable oils changes the handling profile of the whole emulsion. The choice of blend is a formulation trade-off, not a ranking.
MK-7 carries a long isoprenoid tail and needs a fat phase for dispersion and uptake. An oil-in-water emulsion supplies it. Note that a soya-oil-containing vehicle already carries phylloquinone, so the total vitamin K picture involves both forms.
Astaxanthin is a lipophilic xanthophyll that needs an oil vehicle to disperse and is prone to oxidation at its polyene chain. The emulsion droplet supplies the lipid environment; a tocopherol is normally needed alongside it for stability. The relationship is one of carrier to cargo.
Beta-carotene uptake depends on the presence of dietary fat to form mixed micelles, which is why an emulsified oil is a standard vehicle for it. Its conjugated chain also oxidises readily, so antioxidant protection travels with it. This is carrier chemistry.
Mixed tocopherols cover a broader radical profile than alpha-tocopherol alone, and vegetable oil emulsions are commonly stabilised with them. The requirement rises with the polyunsaturated content of the oil blend. This is a product-stability relationship.

An oil-in-water emulsion of this type places triglyceride droplets in an aqueous continuous phase, each droplet stabilised by a monolayer of egg-derived phospholipid whose polar head groups face the water and whose acyl chains face the oil core.
Olive oil is dominated by the monounsaturated fatty acid oleic acid, while soya oil is dominated by the polyunsaturated linoleic acid with a smaller share of alpha-linolenic acid, so a blend of the two sets both the essential fatty acid supply and the number of oxidisable double bonds.
Linoleic acid and alpha-linolenic acid are the two fatty acids humans cannot synthesise, which is why a vegetable oil component appears in emulsions intended to supply fat rather than only to carry a lipophilic ingredient.
Egg lecithin is largely phosphatidylcholine, so the emulsifier layer itself contributes phospholipid and choline in addition to holding the droplets apart.
Where Olive Oil/Soya Oil/Egg Lecithin-Based Emulsion comes from.
Olive and soya oil are mixed with water and a fat from egg yolk that acts as the go-between, then forced through a high-pressure machine that smashes the oil into microscopic droplets. The egg fat wraps each droplet so the mixture stays milky instead of splitting. The checks that matter are droplet size and whether the oil has started to go off.
The same molecule is reached more than one way. Which route a given product used is a manufacturing choice, and the finished compound is the same either way.
Olives are pressed and the oil refined; soybeans are crushed and the oil extracted, then refined, bleached and deodorised.
Hen egg yolk supplies the phospholipid raw material, principally phosphatidylcholine and phosphatidylethanolamine.
The yolk lipid is extracted with solvent and the phospholipid fraction separated from neutral lipids and cholesterol by fractionation.
Both oils are refined to remove free fatty acids, phosphatides, pigments and volatile oxidation products before they enter the emulsion.
The oil, water, phospholipid and a tonicity agent such as glycerol are combined and passed repeatedly through a high-pressure homogeniser, which shears the oil into fine droplets that the phospholipid immediately coats.
Batches are characterised by mean droplet diameter, the fraction of large droplets, peroxide value and free fatty acid content, since all four track physical and oxidative stability.
The finished product is an opaque, uniform white liquid whose appearance itself signals whether the emulsion has separated or creamed.
