Great Supplement!

by Dee with hyper reactive immune system -

Use for rotation diet. This is a precusor supplement meaning that your body only uses what you need. You can take a bit extra without worry of overdose. You can also take 4 doses once every 4 days and it is still effective.

Great stuff

by Dee -

This is a precursor to vitamin D. My nutrition doctor tells me not to worry about overdosing because my body decides when to convert to vitamin D. It works well!

i definately recomment this vitamin

by Bev -

I had difficulty getting my vitamin d level to the normal range with regular over the counter versions of vitamin d. After taking this vitamin d supplement my level was 54, right in the middle of normal. I also noticed the achiness in my legs at the end of the day went away completely:)

This product really works.

by william -

I was having difficulty maintaining an acceptable level of vitamin D. My Nephrologist recommended I try this brand, and it worked! Within 3 months, my level had returned to normal, and it continues to maintain two years later. I am convinced, as I had tried several other brands, and none of them delivered as promised. Keep up the great work!!!

Caught without my regular supply!

by Larry -

I am on a daily Vitamin D regimen prescribed by my physician. Was in a quandry when I couldn't order this product from the manufacturer due to shortage. So glad to find this at a good price from Professional Supplement Center. Shipping was fast! I am incredibly impressed with this product and this company for its fast and efficient service.

Daily supplementation of vitamin D is so important. Have relied on this Bio-Tech product for a long time. High quality at a very reasonable price. A daily "go-to" supplement for me!
