CERTIFIED SUSTAINABILITY & PURITY: All our oil is made in Norway and sourced from wild-caught fish from fisheries certified sustainable by Friends of the Sea and Marin Trust. Every batch is independently tested for heavy metals, PCBs, pollutants, and freshness by IFOS (International Fish Oil Standards).
NUTRITIONISTS' AND HEALTH EXPERTS' CHOICE: Top nutritionists and health experts choose our omega-3 fish oil because of its strength, purity, transparency and fast results.
SMALL FEMALE FOUNDED UK BUSINESS, ESTABLISHED FOR 13 YEARS: We understand the challenge of finding the best quality supplements because we've been there, which is why we're transparent about our ingredients, sustainability, and ethical practices. Our supply chains are certified to the highest quality standards and sourced exclusively from the UK and Norway.

Omega 3 Vegan DHA Drops for Kids - 50mL - No Fishy Taste - Preservative Free and Sugar Free. Sustainable Algal Alternative to Fish Oil | APOKRA Kids

Free Shipping

Why We Love It

Sustainably sourced vegan Omega 3.
Allergen-free with natural flavors.
Supports brain, vision, heart.

Main Highlights

✔ APOKRA OMEGA 3 KIDS – APOKRA’s vegan omega 3 for kids is sustainably sourced from algae and combined with a great tasting, natural orange flavour. Our allergen-free formula is suitable for all diets including vegan, and vegetarian diets; for children aged between 3 months & 12 years old. Kids vitamins are an important supplement to a balanced diet & our omega 3 kids drops can be used alongside a kids multivitamin.
✔ SWISS-SOURCED ALGAE OMEGA 3 FOR KIDS – Sourced from Switzerland, our ethical & sustainable algae omega 3 is of the highest quality & purity. It is combined with an Italian olive oil & natural orange flavour to create an algae oil omega 3 that can be easily mixed with food, and smoothies or taken directly off the dropper.
✔ SUGAR-FREE, ARTIFICIAL SWEETENER-FREE, PRESERVATIVE-FREE & NO UNNECESSARY INGREDIENTS – Great nutrition is at the heart of our ethos, we understand that taking omega 3 is a daily ritual & so we have specifically formulated our omega 3 for kids without any of the unnecessary ingredients. Our formula contains the beneficial level of Omega 3 DHA & EPA plus only 3 other ingredients: Italian olive oil, mixed tocopherols & natural orange flavour.
✔ BENEFICIAL OMEGA 3 DHA & EPA LEVEL PER SERVING FOR BRAIN, VISION & HEART – DHA & EPA are considered the most important omega 3 fatty acids. DHA supplements are important for the brain & vision; each serving provides the beneficial level of DHA for the maintenance of normal brain function & vision as per the EFSA guidelines.
✔ WHAT MAKES OUR OMEGA 3 KIDS DIFFERENT FROM GUMMIES? – gummies typically contain sugar, artificial sweeteners & up to 16 additives. They also usually contain the less efficient plant-based omega 3 fatty acid ALA from perilla oil or flaxseed omega 3 6 9. Our algae omega 3 provides DHA & EPA directly unlike ALA which must be broken down into DHA & EPA by the body. Omega 3 6 9 gummies typically don’t contain the beneficial level of 250mg of DHA & are unable to make the health claim related to DHA contributing to the maintenance of normal brain function & vision.
✔ FISH-FREE OMEGA 3 WITH THE SAME HEALTH BENEFITS AS FISH OIL WITHOUT THE STRONG FISHY TASTE & ODOUR – taste is important to kids. Our vegan omega 3 kids oil contains no fish and therefore doesn’t have the strong fishy flavour and the fishy smell compared with fish oil which makes it a great choice for infants, toddlers and children.
✔ FUSS FREE LIQUID DROPPER INCLUDED - Our vegan Omega 3 DHA drops are provided with a liquid dropper, which is conveniently separated from the bottle for safety and easy cleaning
✔ NO UNNECESSARY INGREDIENTS, PREMIUM QUALITY & ALLERGEN FREE - All formulations undergo pharmaceutical grade end-testing to ensure purity and are vegan, sugar free, nut free, allergen free, preservative free, without artificial colours or flavours
