Trustworthy Thorne Vitamin D — I’ll keep buying it

I’ve been taking Thorne Vitamin D for a while now and it’s become a staple in my supplement routine. The quality is excellent — pure, well-tested, no unnecessary additives. I take it with meals for better absorption and it hasn’t caused any stomach discomfort or bloating. I feel more balanced, my mood is more stable, and I’m confident I’m supporting my bone and immune health properly. Highly recommend — I’ll definitely buy this one over and over.

Great supplement for vitamin d deficiency

I started to take this after fracturing my toe to help boost my calcium absorption and increase my bone health. The ingredient is of good quality and have been working well for me since. It also helps with boosting my vitamin D deficiency since I’m not constantly under the sun.

Great brand, small and easy to swallow.

I take these vitamins daily. I know that Thorne is a reputable brand so I feel comfortable buying them over other brands. I like how little these pills are. They are very easy to take. I am currently pregnant and I have done my research that Vitamin D is extremely important so I take it in supplementation to the Vitamin D already in my prenatal vitamin.

Vitamin D for your immune system.

This dosage of Vitamin D is quite low. I don't know why the daily recommendations are so low. Some people have deficiency and/or have absorption problems due to lattitude and lack of sun exposure and thus 4000 to 5000 UI might be more adequate for them. The size of the capsules is small and the quality of the ingredients is high. Make sure you also use Vitamin K so calcium is redirected to the bones.

Throne the best quality ever.

No matter what supplements I got from this brand, I know I get the best quality of products. I needed a little boost of vitamin d and these were the perfect choices. The minimal dosage was just right for me. Works great, felt almost immediately improvement in my mood. I take them in the morning with breakfast to make sure they absorb well. The capsules are tiny, very easy to consume.
