VitalHealth Hub completely changed how I approach my health. The BMI and calorie calculators are incredibly intuitive. I lost 15 pounds in 3 months just by tracking my TDEE and following the nutrition articles. The results are color-coded and come with personalized suggestions that actually make sense. I recommend it to everyone at my school!

As a personal trainer, I use the TDEE and macro calculators with all my clients. The accuracy is impressive compared to other free tools. The blog articles on strength training and protein intake are backed by real research, not bro-science. I have bookmarked at least 20 articles. The one-rep-max calculator is spot-on with my actual gym numbers.

I am a family medicine physician and I routinely recommend VitalHealth Hub to my patients. The calculators use medically validated formulas (Mifflin-St Jeor for BMR, standard BMI equations) and clearly state they are not a substitute for medical advice. The sleep calculator helped several of my patients with insomnia understand their sleep cycles better. Excellent free resource.

I have been using VitalHealth Hub for six months during my pregnancy. The pregnancy due date calculator was accurate to within 2 days of my ultrasound date. The pregnancy nutrition guide helped me plan balanced meals during each trimester. I also love the water intake calculator — it adjusted recommendations for pregnancy. My only wish is a mobile app for offline use!

After my doctor flagged my cholesterol levels, I found the cholesterol risk calculator and heart health articles on VitalHealth Hub. They helped me understand what my numbers meant and motivated me to change my diet. Six months later, my LDL dropped by 30 points. The blood pressure checker and diabetes risk tools also gave me peace of mind. Truly a life-changing resource.
