How I Raised My Vitamin D Levels to 61

I was told several years ago that my vitamin D levels were low. Did you know if your Vitamin D is low, you are at a higher risk for cancer. My levels were under 30 at that time. Well last year I had breast cancer!!! I have been taking this product for about a year and now my vitamin D levels are at 61! I am soooo thrilled! I really like the dropper. The first one I had did not have the dropper and it was hard to control how many drops.

Understanding Vitamin D and Its Role in Health

Vitamin D is a fat-soluble vitamin crucial for calcium absorption, bone mineralization, and immune function. Research suggests low vitamin D levels may increase the risk of certain cancers, including breast cancer. The user's experience—raising levels from under 30 ng/mL to 61 ng/mL after one year—reflects the importance of maintaining adequate vitamin D for overall wellness.

Key Features of This Vitamin D3 Serum

Premier Research Labs Vitamin D3 Serum delivers 5,000 IU per five-drop dose using naturally sourced liquid vitamin D3 (cholecalciferol). The formula combines D3 with extra virgin olive oil, which enhances absorption because vitamin D is fat-soluble. The olive oil base also contributes to a pleasant taste, as noted in customer reviews.

Bone Health & Immune Support Benefits

Adequate vitamin D supports bone health by promoting calcium and phosphorus absorption, helping to prevent osteoporosis and fractures. It also modulates the immune system, supporting natural defenses against infections and autoimmune conditions. The user's improved immune function aligns with clinical evidence linking vitamin D to reduced infection risk and better overall immunity.

Product Purity and Quality

This serum is non-GMO, Kosher, and free from artificial colors and harmful additives. The liquid form allows easy dosing via a dropper, though some users reported variability in dropper durability. Each bottle provides approximately 114 servings, offering long-term value despite being positioned as a premium-priced supplement.

Dosage and Usage Tips

The recommended serving is 5 drops daily (125 mcg or 5,000 IU). For individuals with diagnosed deficiency or higher needs, consultation with a healthcare provider is advised. Taking drops with a meal containing fat (e.g., olive oil in the formula) maximizes absorption. The dropper design, while generally effective, requires careful handling to avoid breakage.

Link Between Vitamin D and Cancer Risk

Observational studies suggest that maintaining vitamin D levels above 30 ng/mL may lower breast cancer risk. The user's personal history—diagnosed with breast cancer after having low vitamin D—underscores the potential preventive role. However, supplementation should be part of a broader health strategy, not a standalone treatment.

Comparing to Other Vitamin D Supplements

Many D3 supplements use soybean or MCT oil; this product's extra virgin olive oil base is a distinguishing factor, offering additional antioxidants and a clean taste. The 5,000 IU potency is common for therapeutic doses, but lower doses are also available for maintenance. Customer reviews highlight effectiveness in raising serum levels, with some noting the pleasant taste as a motivator for consistent use.

Potential Drawbacks

Some customers found the price high compared to generic brands, and a few reported dropper breaking after extended use. The liquid form may not suit those preferring capsules. Despite these issues, the majority of 645 ratings give it 4.7 stars, indicating high satisfaction with the product's efficacy and quality.

Final Thoughts on This Vitamin D3 Serum

For individuals seeking a potent, clean, and effective vitamin D3 supplement with added immune and bone support, this serum is a strong choice. The user's success in raising levels from 30 to 61 and improved well-being exemplifies the tangible benefits of proper vitamin D supplementation. Combined with a healthy lifestyle, it can significantly contribute to long-term health.
