Frequently Asked Questions
A high-quality Vitamin D supplement should come from a reputable manufacturer and clearly disclose its ingredients, dosage, formulation, and testing. Many shoppers also look for third-party testing, transparent labeling, and quality standards that make it easier to understand what is in the product.
Third-party testing means a supplement has been evaluated by an independent organization or laboratory rather than relying only on the manufacturer's own internal testing. Depending on the program, testing may look at identity, purity, potency, contaminants, or whether the product matches its label claims.
Swell Score Vitamin D products are carefully curated by our medical team with a focus on overall quality. We consider factors such as third-party testing, formulation, ingredient quality, transparency, brand reputation, and how clearly the product communicates what it contains.
Vitamin D2 and Vitamin D3 are two forms of Vitamin D commonly used in supplements. Vitamin D2 is also known as ergocalciferol, while Vitamin D3 is known as cholecalciferol. Many Vitamin D supplements use Vitamin D3, but the best option depends on your individual needs and preferences.
When comparing Vitamin D supplements, consider the form of Vitamin D, amount per serving, additional ingredients, delivery format, third-party testing, brand transparency, and whether the product fits your individual needs. Some people also prefer specific formats such as capsules, softgels, drops, or gummies.
Yes. Vitamin D supplements are available in a wide range of strengths and serving sizes. The appropriate amount varies based on factors such as diet, sun exposure, age, health status, and individual needs, so more is not always better.
Vitamin D is a fat-soluble vitamin, so taking it with a meal that contains some dietary fat may support absorption. Always follow the directions provided on the specific supplement you choose.
Vitamin D is often included in multivitamins and is also commonly paired with nutrients such as calcium or vitamin K. Whether a combination makes sense depends on your individual diet, health needs, medications, and existing supplement routine.
People who have a medical condition, take prescription medications, are pregnant or breastfeeding, or are unsure about the appropriate amount of Vitamin D for their needs should speak with a qualified healthcare professional before starting or changing a supplement routine.
