Many individuals struggle to maintain adequate vitamin D levels, particularly during the darker months, which is why a high-dose supplement like Maximum D3 can be a practicable solution. Each capsule delivers 13,000 IU (325 mcg) of vitamin D3 in a convenient once-weekly format, helping you support normal bone health, calcium absorption, and immune function. This pack contains 5 capsules for a 5-week supply. Manufactured in the USA to high quality standards, Maximum D3 is non-GMO and gluten-free.

Understanding High-Dose Vitamin D3

Vitamin D3 (cholecalciferol) is the most bio-available form of vitamin D, naturally produced in the skin upon sun exposure. It is more effective than vitamin D2 at raising and maintaining blood levels of 25-hydroxyvitamin D. With 13,000 IU per capsule—well above the typical daily recommendation of 600–800 IU for adults—Maximum D3 is designed for weekly uses. This higher dose is intended to correct or maintain optimal levels, especially for those with known deficiencies or increased requirements. Always consult a health care professional to determine the appropriate dosage based on your blood levels.

Who May Benefit from Weekly Vitamin D Supplementation?

• Individuals with limited sun exposure (e.g., living in northern latitudes, working indoors, or covering skin)
• People with darker skin, which requires more sun exposure to produce sufficient vitamin D
• Older adults, as skin synthesis efficiency declines with age
• Those with conditions affecting absorption, such as Crohn's disease or coeliac disease
• People following a vegan diet (note: vitamin D3 in Maximum D3 is typically derived from lanolin; vegans should seek a lichen-based alternative)

A simple blood test can help identify a deficiency. Consult your health care provider before starting a high-dose regimen.

Why Choose Maximum D3?

Vitamin D deficiency is more common than many realise, particularly for those with limited sun exposure or darker skin. Maximum D3 provides a potent 13,000 IU (325 mcg) per capsule in a convenient weekly dose. This high-potency formula is designed to help maintain healthy vitamin D levels, supporting bone health, calcium absorption, and immune function.

Non-GMO, gluten-free, and manufactured in the USA, Maximum D3 is a reliable choice for an effective vitamin D supplement.

How to Uses Maximum D3 for Optimal Results

Take one capsule once a week, preferably with a meal containing fat to enhance absorption—vitamin D is fat-soluble. Consistency is key: incorporate it into your weekly routine, such as every Sunday with breakfast. Each pack contains 5 capsules for a 5-week supply. Store in a cool, dry place away from direct sunlight. Do not exceed the recommended dose unless directed by a health care professional.

Key Benefits of Maximum D3

• Normal Bone Health: Vitamin D contributes to the maintenance of normal bones and teeth by aiding calcium and phosphorus absorption. Adequate levels may reduce the risk of bone loss and fractures as you age.
• Normal Immune Function: Vitamin D plays a role in the normal function of the immune system, helping the body defend against seasonal challenges.
• Calcium Absorption: Vitamin D contributes to normal absorption and utilisation of calcium, essential for bone mineralisation.
• Muscle Function: Vitamin D contributes to the maintenance of normal muscle function, which may help reduce the risk of falls in older adults.

These benefits are supported by EFSA-approved health claims. Individual results may vary.

Safety and Precautions

Vitamin D is generally safe when taken as directed. However, excessive intake can lead to toxicity, characterised by hypercalcaemia (high blood calcium). Symptoms may include nausea, vomiting, weakness, and kidney stones. The tolerable upper intake level for adults is 4,000 IU per day (or 28,000 IU weekly). Maximum D3 provides 13,000 IU per week, which is well below the upper limit. Nonetheless, individuals with certain conditions (e.g., sarcoidosis, kidney disease) or those taking medications that affect vitamin D metabolism should consult a health care professional before uses. Keep out of reach of children.
