I love this

I’ve been taking this for many years now, I need this every winter season, I take 10,000 IU everyday to help me reduce My inflamation, during summer about 5000 IU, the first time I got serious skin allergy but after 1 week of taking the allergies gone for good. Recommended! Look for Dr. Berg for more details about Vitamin D3 . God bless you all guys! Good health and take care!

Doctor's Best Vitamin D3

I bought this product because Doctor's Best used quality ingredients and I need to make sure I get enough Vitamin D3 since I don't expose my skin to the sun regularly. The soft gels are small in size and easy to swallow but each one is packed with a large dosage of 5000 international unit of D3. This is helping me to overcome deficiency and improve the health of my bones. If you take one softgel daily this bottle will last you nearly a year.

Great Quality Product!

I have been on this product for the past several years, and am thankful for the benefits. According to my blood work, it has increased my Vitamin D levels, and is effective in managing them on a daily basis. It is easy on digestion, and great for those who struggle with common allergens. Pros: I enjoy the small size, and that it is a gel capsule for easy swallowing. It is economical, has raised Vitamin D levels in my body significantly (great absorption) and is easy on digestion. The fact they are made from olive oil was the main reason I purchased in the first place and I have continued to reorder. I'm glad if my review is helpful!

Vitamin D3.

Every cell in our body has receptors for vitamin D3. We know that vitamin D3 regulates calcium metabolism in the body, but numerous other functions have also been established. Osteomalacia, osteoporosis, rickets, nonspecific muscle and bone pain, a weak immune system, cancer, cardiovascular diseases, depression, multiple sclerosis, Parkinson's disease, and dementia are all conditions linked to vitamin D3 deficiency.

EXCELLENT PRODUCT

Dr. Best always makes excellent quality products. I buy this vitamin D3 for my sister, as 10,000 units is a bit too much for her, and this 5 is just right.

Vitamin D plays a truly remarkable role in the body for all round health and wellness, from contributing to the normal function of the immune system to the maintenance of normal bones and teeth. The UK Department of Health recommends that everyone should consider a daily supplement of vitamin D especially during the autumn and winter. In addition to vitamin D tablets and gummies, our selection of vitamin D Supplements also includes vitamin D drops for kids.
