FAQs

What are the best supplements for your heart?

There are a range of supplements which help to support the normal function of the heart.

 

Holland & Barrett Vegan Algal Oil Omega 3-6-9 Capsules contain EPA and DHA, which are long chain omega 3 polyunsaturated fatty acids, which contribute to the normal function of the heart.

 

These omega 3s are often found within fish oil supplements and so this algal oil supplement is a great alternative if you are following a vegan or vegetarian diet and cannot otherwise take cod liver oil.

What is flaxseed oil?

Flaxseed is the seed from the flax crop, which is native to Southern Europe and Asia.

 

Flaxseed oil is made from ground and pressed flaxseeds. Flaxseed oil contains the essential omega 3 fatty acid alpha-linolenic acid (ALA) and can used in a wide variety of ways, including in cooking, skincare and dietary supplements.

What is flaxseed oil good for?

Flaxseed oil naturally contains Alpha Linolenic Acid (ALA), an omega 3 fatty acid which the body is unable to produce on its own and therefore one which must be obtained via your diet. ALA contributes to the maintenance of normal blood cholesterol levels, when at least 2g are ingested per day.

Which foods naturally contain the essential omega 3 fatty acid alpha-linolenic acid (ALA)?

As well as flaxseed, other great food sources of ALA include soybeans, pumpkin seeds and walnuts.

 

If you do not feel as if you are getting enough ALA in your diet, then it might be a good idea to start taking a daily supplement such as Holland & Barrett Flaxseed Linseed Oil Capsules.

How much omega 3-6-9 should I take daily?

The NHS recommends that we should include at least one portion of oily fish in our diets each week in order to get our recommended allowance of omega 3 fatty acids.

 

However, if you do not like oily fish then it can be difficult to get enough omega 3. Therefore, it is a good idea to take a daily supplement to keep your levels topped up.

 

It is advised that you take two of the Holland & Barrett Maximum Strength Triple Omega 3-6-9 Capsules each day, preferably with meals.

What is the difference between omega 3 and omega 3-6-9?

Omega 3, omega 6 and omega 9 are all different types of fatty acids.

 

An omega 3-6-9 supplement is one which quite simply contains all of them, whereas an omega 3 supplement will just contain omega 3.
