Bio-Tech D3-5 5000 Iu 250 Caps

Great Vitamin D! Miss the lower dose though and wish the company would bring it back.

I started using this brand when a clinical trial I was in used this brand saying that they'd found it to be the best available. I've been buying this for a decade or more by now and my D levels stay right in the correct range (based on my blood test results). The 5000 IU dosage may be too large for some folks, so one should be sure to test one's D blood levels to make sure of the correct dosage for oneself. By frequent initial blood tests, I have found I need 10,000 IU to maintain my D level, so this is a good dosage pill for me. Your mileage may vary. ;-)

Buen producto

When my previous Vit.D3 supplement did qnot have me in the therapeutic range, I inquired as to what different product I would take would be better. I was told Bio-Tech and so ordered some, which I have been taking and the results are far better Vit.D3 levels than prior to taking Bio-Tech. For me, the proof was in the numbers.

They delivered quickly. It is a great product for maintaining my vitamin D levels and addressing my previous deficiency. I was very deficient for years until I started using this product. Before this I had to get vitamin D injections because nothing else worked.

Was exactly what was able to get when before having to go several miles to get, and at a good price.

Have been taking this kind of Vit D and have been very pleased with the results.

Love it! Been taking this vitamin since my doc asked me too. Need it for reasons that I have a low vitamin D deficiency since I have had cancer in 2016. Been taking it since then and my readings and my health couldn’t be better!
