Buy Heart & Blood Vessel Supplements: Omega 3, Potassium and More at a Glance

In the Heart & Blood Vessel collection, you will find omega 3 fish oil with EPA and DHA, coenzyme Q10 and ubiquinol, citrus bergamot, potassium and olive leaf extract, plus combined formulas such as Heart Essentials. Permitted health claims apply to some of these nutrients: EPA and DHA contribute to the normal function of the heart (with a daily intake of 250 mg of EPA and DHA), and potassium contributes to the maintenance of normal blood pressure. There are no permitted health claims for the other ingredients; we describe them neutrally below.

The range includes various forms and dosages: softgels and capsules containing fish oil in triglyceride form, vegan omega 3 from algae oil, krill oil, Q10 as ubiquinone or ubiquinol, potassium citrate tablets and plant extract capsules. The products come from brands such as Vit4ever, NOW Foods, Swanson, German Elite Nutrition, ESN, Nuvi Health and LUTO Supplements, allowing you to compare both individual ingredients and broader combination formulas.

What Can You Find in the Heart & Blood Vessel Collection?

This collection brings together a variety of ingredients. Broadly speaking, they fall into three groups: the omega 3 fatty acids EPA and DHA from fish, krill and algae oil, minerals such as potassium, and plant extracts such as citrus bergamot and olive leaf. There are also formulas that combine multiple ingredients. Below, we explain what each group is and what to look out for.

Omega 3 with EPA and DHA

You get the fatty acids EPA and DHA from oily fish or a supplement. EPA and DHA contribute to the normal function of the heart; this effect is obtained with a daily intake of 250 mg of EPA and DHA. In the collection, you will find fish oil in triglyceride form, krill oil with astaxanthin and vegan omega 3 from algae oil, so there is also a plant-based option.

Coenzyme Q10 and Ubiquinol

Coenzyme Q10 is a substance naturally produced by the body that is found in virtually every cell. You will find Q10 in two forms: ubiquinone (the oxidized form, often the most affordable) and ubiquinol (the reduced form). The choice is mainly a matter of preference and budget. The range includes, among other things, coenzyme Q10 250 mg in capsule form and ubiquinol 100 mg in softgels. There are no permitted health claims for Q10, so we describe the product here without any performance claims.

Citrus Bergamot

Citrus bergamot (Citrus bergamia) is a citrus fruit that grows mainly on the coast of Calabria in southern Italy. The extract contains polyphenols and is usually offered as a supplement in capsule form, sometimes standardized to a fixed polyphenol content and combined with piperine from black pepper. There are no permitted health claims for citrus bergamot, so we describe the extract purely descriptively: origin, form and content. Always check the label for the exact composition.

Potassium

Potassium is a mineral and an electrolyte. Potassium contributes to the maintenance of normal blood pressure and to the normal function of the muscles and nervous system. These permitted health claims apply to products that provide a significant amount of potassium per daily dose (at least 15% of the reference intake, 300 mg); check the content on the label. In the collection, you will find potassium as potassium citrate in capsules and as a tablet with a fruit & greens blend. Stick to the recommended dosage on the label for potassium.

Olive Leaf and Combination Formulas

Olive leaf extract comes from the leaves of the olive tree (Olea europaea) and is often standardized to oleuropein. It is a classic Mediterranean plant extract that is available as a capsule; we also use a descriptive text without a performance claim for this. In addition, the collection contains broader formulas such as Heart Essentials, in which plant extracts are combined with coenzyme Q10 and vitamin B1 (thiamine). Such combination products are useful if you want multiple ingredients in one capsule; you can read the exact composition on the label.

Dosage and What to Look Out for When Buying

Which dosage and form are right for you depends on your preference. When buying, pay attention to the content per capsule or tablet (for example, the amount of EPA and DHA, mg of Q10 or mg of potassium), the form (softgel, capsule or tablet), whether the product is vegan and the number of doses per package. Also compare whether you are looking for an individual ingredient or a combination formula. Use supplements as a supplement to a varied diet, not as a replacement. Always use the directions on the package as a guide for the correct daily amount.

What Are These Ingredients Naturally Found In?

Many ingredients in this collection are also found in regular food: the fatty acids EPA and DHA occur naturally in oily fish such as salmon, mackerel and herring, and in algae. You get potassium from, among other things, vegetables, fruit, legumes and nuts. Plant-based ingredients such as citrus bergamot and olive leaf come from the bergamot citrus fruit and the leaves of the olive tree, respectively.

When Do You Take These Supplements?

The time of intake depends on the specific product and form. Omega 3 softgels and other fat-soluble supplements are often taken with a meal, while capsules and tablets are usually swallowed with some water. Some people spread the intake throughout the day, for example at breakfast and dinner. Always follow the directions on the package for the recommended time and frequency. If you are taking medication, consult your GP or pharmacist first.
