Very happy with TriVita's products!

Great product with herbal supplements from the Amazon Rainforest


I went to India for a 3 week Yoga retreat in India - I sipped on the Vital C Powder in Water on the long flight. It was flu season. I spent 3 weeks in India and almost all the other people in the retreat got sick. I did not. I kept sipping on my Vital C Powder in water throughout the trip and on the flight home. I feel great. I've never had a better and healthier winter since taking the Vital C Powder. I am 75 years old.

I love how this helps me relax after a stressful work day. I find that it allows me to rest peacefully at night. Sometimes, I go to the gym after work, which energizes me too much and this helps me get back to a peaceful state so I can fall asleep quickly. Also, I find the grape taste delicious. It\'s the perfect evening drink!

I had a cough that I was not able to get rid of. I started on the Vital C Powder and Tablets and it cleared up my stubborn cough.

Amazing product . . . The cartilage in my knees has improved.

Best product out there for memory!!!!

Bone Growth Factor - "I fell in my kitchen and landed hard on my hip. My first thought was I broke my hip. When I got checked out, the doctor was amazed I hadn't sheered off my bone but there was no crack, or fracture or break. I attribute this to Bone Growth Factor and the good Lord for protecting me. Update 1/2021: I had a bad fall at age 68 right onto my left hip. The Dr. thought that I might need a hip replacement but thanks to Bo9ne Growth Factor and the support it gave my bones, there is no need for a replacement. Everyone needs Bone growth Factor to strengthen their bones.
