Enervia combines six ingredients in one daily capsule. Three of them (DHA, phosphatidylserine and choline) are fats or fat-related nutrients that form part of brain tissue. The other three play supporting roles. Below, we explain each one, what it does and, most importantly, what the evidence actually says. We don't just repeat the seller's copy.
Enervia ingredients at a glance
| Ingredient | Main food source | Approved UK claim? |
|---|---|---|
| DHA (cod liver oil) | Oily fish | Yes, at 250 mg/day |
| Phosphatidylserine | Fish, offal, soya | No |
| Choline | Eggs, meat, fish | Yes (lipid, liver) |
| Lion's mane | Mushroom | No |
| Vitamin B12 | Meat, fish, dairy | Yes (tiredness, psychological function) |
| Astaxanthin | Salmon, krill | No |
DHA from wild cod liver oil
Structural omega-3 fat
DHA (docosahexaenoic acid) is an omega-3 fatty acid found in high concentrations in the membranes of brain cells. Our bodies make very little of it, so it mostly comes from oily fish such as salmon, mackerel and sardines. Many UK adults eat less oily fish than the one portion a week the NHS recommends, which is the main reason people look at DHA supplements. Cod liver oil also naturally contains vitamins A and D.
Evidence: Authorised GB health claim: DHA contributes to the maintenance of normal brain function, with the benefit obtained from 250 mg DHA a day. We could not confirm Enervia's DHA amount per capsule.
Phosphatidylserine
Cell membrane phospholipid
Phosphatidylserine is a phospholipid, a type of fat that forms part of every cell membrane and is especially concentrated in nerve tissue. Small amounts come from foods such as fish, offal and soya. It has been studied in older adults in relation to memory, with mixed and generally modest results, and most of the older studies used a bovine-derived form that is no longer sold.
Evidence: No authorised GB health claim. Evidence is limited and inconsistent.
Choline
Building block for acetylcholine
Choline is an essential nutrient the body uses to make acetylcholine, a chemical messenger involved in memory and muscle control, and to build cell membranes. Eggs, meat, fish and dairy are the main dietary sources, so people who eat few animal foods may get less of it.
Evidence: Authorised GB claims: contributes to normal lipid metabolism, normal homocysteine metabolism and the maintenance of normal liver function.

Lion's mane
Mushroom extract
Lion's mane (Hericium erinaceus) is an edible mushroom with a long history in East Asian cooking and traditional use. It has become popular in cognitive supplements after laboratory studies on nerve growth factors. Human studies so far are small and short.
Evidence: No authorised GB health claim. Early-stage human research only.
Vitamin B12
Essential vitamin
Vitamin B12 is needed for healthy nerves and red blood cells. It is found almost only in animal foods, and absorption tends to fall with age, so B12 is a common addition to supplements aimed at older adults.
Evidence: Authorised GB claims: contributes to normal psychological function, normal functioning of the nervous system, and the reduction of tiredness and fatigue.
Astaxanthin
Carotenoid pigment
Astaxanthin is the red-orange pigment that colours salmon, prawns and krill. It is included for its antioxidant properties and may also help protect the oil in the capsule.
Evidence: No authorised GB health claim.
What's missing from the label information
The seller's homepage doesn't list the milligram amount of each ingredient. This matters for two reasons. Firstly, the DHA brain-function claim only applies at 250 mg a day, so without the figure we can't say whether Enervia reaches it. Secondly, if you already take fish oil, cod liver oil, a multivitamin or a B12 supplement, you need the amounts to avoid doubling up, particularly on vitamin A. Check the full label on the official site before buying.
How Enervia's formula compares with single supplements
You could buy cod liver oil and vitamin B12 separately for less money. What Enervia adds is phosphatidylserine, choline, lion's mane and astaxanthin in a single capsule. Whether that's worth the price depends on how much you value one simple daily habit. We compare the two options in detail in Enervia vs cod liver oil.
Enervia may suit you if…
- You eat little oily fish
- You want one simple capsule a day
- You prefer nutrients to stimulants
- You're happy to give it around 8 weeks
Skip it or ask a GP first if…
- You have a fish allergy
- You're pregnant or breastfeeding
- You take blood thinners
- You already take cod liver oil or vitamin A
Enervia ingredients: FAQs
What are the main ingredients in Enervia?
Enervia's key ingredients are DHA from wild cod liver oil, phosphatidylserine and choline. Supporting ingredients are lion's mane mushroom extract, vitamin B12 and astaxanthin.
Does Enervia contain fish?
Yes. Its DHA comes from cod liver oil, so it is not suitable for anyone with a fish allergy, or for vegans and vegetarians.
How much DHA is in each Enervia capsule?
The seller's website does not state the milligram amount per capsule. UK rules only allow the DHA brain-function claim where a product provides 250 mg of DHA a day, so check the full label before buying.
Does Enervia contain caffeine or stimulants?
No stimulants are listed. Enervia is built around fats and nutrients rather than caffeine, so it shouldn't give a quick buzz or a crash.
Is Enervia gluten-free or dairy-free?
The seller doesn't publish full allergen information beyond fish. If you have a food allergy, check the label on the official site or contact the seller before ordering.
Which Enervia ingredients have approved health claims?
In Great Britain, DHA (at 250 mg a day), choline and vitamin B12 carry authorised health claims. Phosphatidylserine, lion's mane and astaxanthin do not.
