Why do I need this report?

Vitamin C is an essential nutrient—your body can’t make it—yet individuals can differ in how easily they maintain optimal vitamin C levels. This report helps you understand whether your genetics suggest a higher dietary need, a tendency toward lower circulating levels, or a greater benefit from consistent intake. With that clarity, you can make more informed choices to support key functions like antioxidant protection, collagen production, immunity, and overall cardiometabolic health—without relying on one-size-fits-all advice.

Why is this report unique?

Most vitamin C guidance is generic (e.g., “eat more citrus”), but your needs may not be. This report is unique because it evaluates 11 vitamin C-related genetic variants and converts them into 36 personalized recommendations you can actually use—covering both food strategies and supplement options. It also connects your results to practical outcomes like supporting collagen formation and oxidative stress balance, so you understand the “why” behind each recommendation.

How is the recommendations list built?

Your recommendations are built by combining your genotype results across the 11 analyzed variants with a structured evidence review of published research. Actions are prioritized based on (1) the predicted impact of each variant on vitamin C status or related pathways, (2) the strength and consistency of scientific evidence, and (3) practicality and safety. When multiple variants point in the same direction (for example, toward lower vitamin C levels), the report elevates the most relevant dietary and supplement steps to help you close the gap efficiently.

How much vitamin C do I need per day based on my genetics?

Most adults need about 90 mg of vitamin C per day, but your genetic profile may suggest you’re more likely to run lower vitamin C levels or benefit from more consistent intake. The Vitamin C DNA Report doesn’t just repeat population guidelines—it evaluates genetic markers associated with vitamin C status and translates them into personalized targets and strategies. Depending on your results and lifestyle factors (such as smoking or breastfeeding), the report may emphasize higher dietary density of vitamin C-rich foods and, when appropriate, a supplement plan designed to help you reliably meet your needs.

What are the best vitamin C foods and should I take a supplement?

Top dietary sources include red pepper, broccoli, tomatoes, oranges, grapefruit, and kiwifruit—foods that can help many people reach daily needs through diet alone. However, genetics can influence how efficiently you maintain healthy vitamin C levels, which may change how strongly you benefit from food-first strategies versus adding a supplement. This report provides personalized dietary guidance (which foods to prioritize and how to build them into your routine) and supplement recommendations when indicated, focusing on safe, evidence-based approaches rather than megadosing.

Understanding Your Vitamin C Risks: A DNA-Based Report

Do you eat “healthy” but still wonder if you’re getting enough vitamin C? Are you trying to support immunity, skin health, or recovery from workouts and injuries—and not sure whether food alone is enough? What if your genes influence how much vitamin C you need from your diet to maintain optimal levels? The Vitamin C DNA Report helps you understand your personal vitamin C needs so you can make smarter nutrition choices with confidence.

Key Report Highlights

This report analyzes 11 genetic variants (SNPs) linked to vitamin C status and how your body may maintain healthy levels, then translates your results into 36 actionable recommendations. Vitamin C is essential because humans lost the ability to produce it internally millions of years ago—meaning 100% of your vitamin C must come from diet or supplements. Since vitamin C supports antioxidant defenses and collagen production, optimizing your intake can impact immunity, heart and lung health, wound healing, and skin and bone health.

Personalized, Actionable Recommendations

Your recommendations are personalized to your DNA results, lifestyle factors, and evidence-based nutrition science—so you’re not guessing or following generic advice. You’ll receive targeted dietary recommendations (e.g., emphasizing high–vitamin C foods like red pepper, kiwifruit, broccoli, citrus, and tomatoes based on your genetic predisposition) and supplement recommendations when appropriate (e.g., guidance on whether a daily vitamin C supplement may be beneficial, plus practical tips on timing and consistency). The goal is simple: help you meet your personal vitamin C needs in a realistic, sustainable way.

User-Friendly Format and Trust

The user-friendly format of this report emphasizes clarity, offering practical, easy-to-follow insights to integrate seamlessly into your lifestyle. Whether you’re a novice or seasoned biohacker, you’ll find the layout accessible and the information straightforward.

This report is grounded in the latest scientific research and trusted by over 150,000 users and 1,000+ doctors worldwide. It’s not only comprehensive but also complies with stringent privacy laws, being HIPAA and GDPR compliant.

This was so simple, even made me want to eat cabbage!

Tangerines fixed my C gap.

Rated 5 out of 5
I bought the Vitamin C nutrition report because I bruise easily and my dad has always had slow wound healing, so I wondered if I was missing something basic. The report explained my likely higher need in a way that finally felt personalized, not generic. I started adding tangerines to my afternoon snack, plus cabbage and radishes into salads a few times a week, and I made a simple “fruits and vegetables” target per day. Within three weeks my gums bled less when flossing and my skin looked brighter. The food suggestions were practical and easy to follow.

I shared my vitamin c results with my nutritionist, who was impressed by how tailored the food suggestions were. She actually agreed with most of them and said this kind of personalized info is helpful, especially the bit about shilajit. It’s useful to have something to bring into appointments.
