Which Vitamin D is Best for You?
The best vitamin D supplements are those that can provide the optimum level of vitamin D that your body needs. This can vary depending on your age, body weight, skin pigmentation and baseline levels.
Benefits of vitamin D include:
- Supporting normal bone health.
- Contributing to immune health.
- Helping normal muscle function.
- Maintaining normal healthy teeth.
At BetterYou, our vitamin D supplements are pill-free oral sprays, meaning you don’t have to take a tablet. Simply spray the supplement into your mouth and continue about your day.
This means it bypasses the digestive system, making for a fast-acting, effective and easy-to-use alternative for getting your daily recommended nutrients.
How Much Vitamin D Do You Need Per Day?
To find the best vitamin D supplements for you and your family, you’ll need to know how much you should take to support your health. The right dosage of vitamin D depends on various factors, such as age.

BetterYou Know
Sometimes the amount of vitamin D is expressed as International Units (IU), where 1 µg is equal to 40 IU. Therefore, a daily supplement of 10 µg is equal to 400 IU.
In order to avoid vitamin D deficiency (where nutrient levels get too low), we recommend a dosage based on body weight. For most adults, this usually equates to around 3000 IU of vitamin D3 per day.
The safe upper limit for vitamin D is 4000 IU (100 μg) per day for anyone over the age of nine years old. This is the maximum daily intake unlikely to cause harmful effects on health.

- Delivers 4000 IU of vitamin D per daily spray.
- Natural peppermint flavour.
- Quickly enters the bloodstream through the soft tissues of the mouth, as opposed to digesting a tablet or capsule supplement.
This is the recommended safe upper limit of vitamin D, designed to help provide maximum-strength vitamin D and help people recover from deficiency.
Best Vitamin D for Adults
The best vitamin D supplement for women, men and children over 13 years old is our Vitamin D 3000 IU Oral Spray.
- This pill-free supplement provides the optimal dosage for adults living in the northern hemisphere in a single daily spray.

Best Vitamin D for Vegans
The best vitamin D supplements for vegans are those that help bridge any gaps in their diet and lifestyle without using any animal products.
The vitamin D in our non-vegan supplements is sourced from Lanolin, which comes from sheep wool. Those following a vegan or plant-based diet may not wish to use it.
However, our vegan supplements use only plant-based sources to help provide essential nutrients. Since the ‘sunshine vitamin’ is often found in meat, dairy, and eggs, someone with a vegan diet may be at risk of low levels and should consider taking vegan supplements.
For vegans, we recommend our Vegan Health Oral Spray.
- Delivers a fast absorbing and effective dose of vegan Vitamin D3 (3000IU / 75μg), Vitamin B12 (6μg), Iron (5mg) and Iodine (150μg).
- The vitamin D source in our vegan vitamin D supplement is Vitamin D3VⓇ.
- Vitamin D3VⓇ is sourced from algae and is fully vegan-approved by the Vegetarian Society.
Best Vitamin D for Vegetarians
The best vitamin D for vegetarians is our Vitamin D 3000 IU Oral Spray, which provides the optimum intake for adults.
All of our vegetarian supplements and vitamin D supplements are suitable for vegetarian diets and are approved by the Vegetarian Society.
Although vegetarians may have a less restricted diet than vegans, they may still see some nutrients underrepresented. Vitamin D is found in fish and beef liver, meaning it’s often a useful supplement to take if you follow a vegetarian diet. Learn more about which supplements vegetarians should take with our guide.

What is the Best Vitamin D for Bone Support?
Depending on your diet and nutritional needs, sometimes the best vitamin D supplements include a combination of vitamins. While vitamin D contributes to your bone health, combining it with other nutrients can help provide optimum support and efficiency.
For example, vitamin D and vitamin K work together to support bone and immune health. Vitamin D supports calcium absorption, while vitamin K ensures calcium moves along the bloodstream and can enter the bones where it’s needed most.
Adults
The best vitamin D supplement with added vitamin K is our Vitamin D+K2 Oral Spray.
- Delivers 3000 IU (75 μg) of vitamin D3 and 75 μg of vitamin K2 in each daily dose (3 sprays).
- Natural peppermint flavour.
- If you are taking anticoagulants (blood thinners) only take this product on the advice of a doctor.
Children
The best vitamin D bone supplement for children aged one year and above is our Vitamin D + K2 Kids’ Oral Spray.
This great-tasting, natural blueberry-bubblegum flavoured oral spray delivers 800 IU of vitamin D3 and 20 μg of vitamin K2 with two quick sprays.
The daily dose can be adjusted for children of different ages:
