How It Works

Discover your vitamin levels with our easy-to-use at-home blood test. Simply use the provided kit to collect a blood sample via a finger prick. The test should be conducted on an empty stomach in the morning. After collecting your sample, send it to our laboratory. Our experts will analyze your sample and provide digital results swiftly, ensuring you get accurate insights into your vitamin status.

Understanding Vitamin A

Vitamin A, a crucial fat-soluble vitamin, is predominantly found in animal foods. Notably, it is essential for normal vision and skin health. Moreover, it plays a pivotal role in embryonic development, particularly in ensuring normal vision.

The Importance of Niacin/Vitamin B3

Niacin, a vital water-soluble B vitamin, is key for energy production and nervous system health. Although niacin deficiency is rare, it's important to understand your levels to prevent conditions like pellagra. Consequently, regular monitoring of niacin can provide valuable health insights.

Pantothenic Acid/Vitamin B5 Benefits

Furthermore, Pantothenic acid, which is widely available in various foods, is essential for energy metabolism and mental performance. Analyzing this vitamin is beneficial in understanding and optimizing your body's energy utilization. Therefore, assessing Pantothenic acid levels can significantly contribute to your overall health strategy.

Biotin/Vitamin B7 Insights

Similarly, Biotin, another crucial water-soluble B vitamin, plays an integral role in macronutrient metabolism and maintaining healthy skin and hair. Additionally, analyzing biotin levels can help identify deficiencies that might lead to skin and hair issues, thereby aiding in preventative health care.
