1st double-concentrated DHA supplement derived from algae, containing 550mg DHA in a single plant-based omega-3 capsule. Be confident you’re supporting your long-term brain health as DHA contributes to the maintenance of normal brain function & vision [1]. Maternal DHA intake contributes to the normal brain development of the foetus and breastfed infants [11].

1-a-day. Single capsule dose
100% more DHA per capsule (compared to normal fish and plant-based omega 3's)
Ideal for healthy agers, diets low in oily fish and pregnant or breastfeeding mothers
Free-from marine pollutants and carrageenan

Our omega-3 DHA supplements are manufactured in an FDA-registered facility in the UK under strict GMP, ISO 9001, and ISO 22000 certified conditions.

43 studies link DHA & brain function

brain feed analysed 43 published trials confirming DHA’s role in brain function.

what is DHA ? The omega-3 for brain health

DHA, an omega 3 fatty acid, contributes to the maintenance of normal brain function[1]. Composing 25% of your brains structure [2], it’s DHA rather than omega-3, EPA or any DHA:EPA ratio that has the EU certified brain health claims.

DHA benefits - Invest in your brain's future

Healthy agers

In healthy young adults with diets low in DHA, supplementation improved memory [3]. In 30-54 year olds, omega 3 improved executive function in participants with low DHA levels [4]. As you age, your body's ability to create new connective tissues slows. DHA has neuroprotective effects [5] and supplementation improved working memory [6].

Studies also show that ensuring a high daily omega-3 intake slows down ageing markers, helping the body age more slowly at the biological level compared to its actual age[7,8]

Diets with low intake of oily fish.

68% of US adults and 95% of children are deficient in omega 3, while 75% of British people miss the daily recommended amount of oily fish [9,10].

Pregnant & breastfeeding mothers

Maternal DHA intake contributes to normal brain & eye development of the foetus & breastfed infants [11]. Consumption of omega 3 increases DHA levels in breast milk [12].

how does DHA work ?

dha-benefits-dha-brain-function.jpg__PID:177b013e-8424-4d06-a8ef-c6d1b81e7747

DHA supports brain function by helping brain cells adapt and survive as you age, by creating a special compound that helps brain cells grow, connect better, and protect against inflammation [13] .

algae fermentation technology

Fish don't produce omega-3 themselves; they are rich in it because they eat algae.[14]. brain feed’s algae omega 3 is marine pollutant free and sourced via a closed loop fermentation process. The fermentation process doubles the concentration of the DHA in the omega-3 oil. After fermentation, the algae oil is chilled to near freezing, removing impurities. 5 control points are monitored, and vitamin E is added at the encapsulation stage to prevent oxidation preserving the health benefits.

FAQ's

What is optimal brain function?

+ -

Maintaining normal brain function is important for working memory and executive function. This is often reflected in the speed at which we can successfully analyse data and execute tasks.

What is neurogenesis and is it impacted by age?

+ -

The brains ability to create new connective tissue decreases with age [15] but diet can play an important role [16]. DHA supports the durability & performance of the brain's structure.[17]

Are there other health benefits of DHA?

+ -

DHA contributes to the maintenance of normal vision in healthy adultsᶧ [18].
Maternal intake contributes to the normal development of the eye of the foetus & breastfed infantsᶧᶧ [9].
DHA also has the following UK & EU cardiovascular health claims for maintaining normal blood pressureᶧᶧᶧ[19], contributing to the normal function of the heartᶧᶧᶧᶧ[19] and contributing to normal blood triglyceride levelsᶧᶧᶧᶧᶧ[20]

Are there any side effects of DHA?

+ -

There are no reported side effects for Algal Omega 3 containing 550mg DHA

Could I have a DHA or omega 3 deficiency?

+ -

The UK & US have very low levels of DHA due to the western diet [7]. 68% of U.S. adults & 95% of children, do not consume enough Omega 3 in their diet to meet U.S. Dietary Guidelines [7]. Only 25% [8] of the UK population consume oily fish. The recommendation is 2 portions of fish per week [at least one should be oily]

How do I take it?

+ -

1 softgel algae oil capsule per day with a large glass of water. Blend into a smoothie if desirable.

How long does it take to have an effect?

+ -

High-dose supplementation of DHA has been shown to begin increasing DHA levels after a month and maintain the levels throughout the supplementation period[14]. DHA concentrations peak at 18 weeks and return to baseline after supplementation has been stopped[15].

Does it contain Carrageenan ?

+ -

Our DHA Omega-3 capsules are completely free from carrageenan.

What does DHA do ?

+ -

DHA is especially concentrated in connective tissue and forms an integral part of cell membranes. It supports the growth of dendrites (connective fibres) [12,13,14] which form new connections in a process known as neurogenesis.

Is there a link between low DHA and cognitive decline?

+ -

Some patient groups with cognitive decline have been shown to be low in DHA [9,10,12,17].

Does algae oil taste fishy ?

+ -

Low quality fish or algae oil will taste fishy because it has oxidised however our quality controls mean we have the best oxidation data in the sector. The oil is kept in cold storage before being twice filtered. We control exposure, temperature, and humidity during the encapsulation process. We add antioxidants to reduce in-capsule-oxidation and finally, our technical packaging contains permanent UV light & moisture barriers.
