Source Naturals Vitamin D3 Liquid Drops, 2000 IU, 60ml (approx. 2 fl oz)

How Vitamin D3 Supports Your Health

Vitamin D is essential for keeping your body functioning properly, yet many people in the UK don't get enough from sunlight alone, particularly during the darker months. Source Naturals Vitamin D3 Liquid Drops offer a simple and effective way to top up your levels. Each serving provides 2000 IU of vitamin D3 (cholecalciferol) – the same form your skin produces when exposed to sunlight – in a convenient liquid format that allows for flexible dosing and easy absorption.

• Bone Health: Vitamin D contributes to the maintenance of normal bones by helping your body absorb calcium and phosphorus.
• Immune Function: Vitamin D contributes to the normal function of the immune system.
• Muscle Function: Vitamin D contributes to the maintenance of normal muscle function.
• Calcium Balance: Vitamin D helps maintain normal blood calcium levels.

These benefits are supported by EFSA-approved health claims and reflect the role of vitamin D in normal bodily functions.

Simple Daily Dosing with Flexible Drops

The recommended serving is 9 drops once daily, which provides 2000 IU of vitamin D3. You can add the drops to a drink (water, juice, or smoothie) or take them directly. Because vitamin D is fat-soluble, taking it with a meal that contains healthy fats can optimise absorption. The dropper allows for precise dosing, and the 60ml bottle provides approximately 60 servings (based on 9 drops per serving).

If you need a higher or lower dosage, the liquid format offers flexibility – but it is wise not to exceed 4000 IU per day without professional guidance. Always consult a health care professional before starting a new supplement regimen.

Vitamin D3 vs D2 – What's the Difference?

Vitamin D comes in two main forms: D2 (ergocalciferol) from plant sources such as mushrooms exposed to UV light, and D3 (cholecalciferol) which is naturally synthesised in human skin when exposed to sunlight. Research suggests that D3 is more effective at raising and maintaining blood levels of vitamin D compared to D2. Source Naturals use cholecalciferol, the preferred form for supplementation, to ensure your body gets what it needs efficiently. As a fat-soluble vitamin, taking it with food can improve absorption.

Who Might Need Extra Vitamin D?

Certain groups are more likely to have low vitamin D levels and may benefit from supplementation. These include individuals with limited sun exposure (especially in the UK during autumn and winter), people with darker skin (which produces less vitamin D from sunlight), older adults (whose skin synthesises vitamin D less effectively), and those who spend most of their time indoors. Note that Source Naturals D3 is derived from lanolin, so it is not suitable for vegans. If you suspect a deficiency, a blood test can help determine the appropriate dosage.

Liquid drops are particularly user-friendly for people who find tablets hard to swallow, and for parents wishing to add vitamin D to a child's drink (whilst paediatric guidance should be sought).

Quality You Can Trust

Source Naturals has been a trusted name in the supplement industry for over 40 years. This product is manufactured in Scotts Valley, California, under strict Good Manufacturing Practises (cGMP). The liquid vitamin D3 contains just two ingredients – vitamin D3 and olive oil – with no unnecessary additives. It is tasteless when added to beverages and provides rapid absorption. The 2000 IU strength is a common maintenance dose for adults, and customers praise the easy-to-use dropper and consistent quality.

Important Safety Information

Vitamin D is generally safe at recommended dosages, but excessive intake over long periods can lead to toxicity. Do not exceed the recommended serving unless advised by a health care professional. If you have a medical condition such as hypercalcaemia, or are taking medications that affect vitamin D metabolism (e.g., certain diuretics or corticosteroids), consult your doctor before use.
