Great quality Vitamin D! I really like Thorne products because the ingredients are simple and the quality is excellent. The capsules are easy to take, and I’m very happy with my purchase. Definitely recommend!
High quality, powder rather than oil, needed the vitamin looks to be working
High quality vitamin D as expected from Thorne. The capsules are small and easy to take. I use it daily and like that it’s 5,000 IU in one capsule. No side effects and great for maintaining my levels. Trust this brand and will repurchase.
Product matches the description. Packaging was fine and delivery was on time, with no visible damage upon arrival. So far, no issues, and everything appears to be in order based on my experience up to this point.
Quality: Premium high-dose Vitamin D3 from a top-quality brand. Size: Small capsule, very easy to swallow. Dosage: Once daily. Benefit: Supports bone health, brain function, and immunity. Package: High-quality bottle with easy-open cap. Taste: No smell or taste. Other Aspects: I always take Vitamin D because I lack sunlight. I’ve tried many types, but this one is one of my favorites for purity and effectiveness. The only downside is that Thorne products can be expensive, so I buy them when there’s a sale.
I really like to order supplements from this brand. The quality is excellent. I always take vitamin d during the winter since i can't get enought from sun. The size of capsules are small, easy to swallow and dosage is olso ok, 1 capsule/day. And I say that the price is very good considering the quality standard.
Took a week to ship here, the package was kinda wet when it arrived but thats ok cuz it was sealed nice all around, they got some small air pillows in the package, and the quality is nice and clean, the ingredients r top notch, overall its really nice nothing to complain abt.
These vitamin D capsules in this dosage keep me going, especially on days when there is no sun. I buy them for all my family members. We live in a rainy area, where it is often cloudy and drizzly. We feel the lack of sunlight and warmth, especially during the cold season. Our immune system needs this support.
The quality of the ingredient, size and dosage of Thorne is the best that America has to offer. Now this brand is a boutique type, and to find their premium D vitamin at this price is an immunity boosting no brainer! The effect is clear in motivation felt after taking it!
I’ve been taking Thorne D-5,000 for a few months, and it’s noticeable how it supports my energy, mood, and overall immunity, especially during the darker months. The capsules are small and easy to swallow, which is a big plus. I trust Thorne for their clean, well-tested supplements — no fillers, additives, or unnecessary ingredients. One capsule a day is enough, making it very convenient. Worth every penny for anyone looking to maintain optimal vitamin D levels safely and effectively.
