11 best thorne research vitamin d3 supplements

Thorne Research is a company that produces dietary supplements, including Vitamin D3 supplements. Vitamin D3, also known as cholecalciferol, is a form of vitamin D that is important for various bodily functions, including the absorption of calcium and maintenance of bone health.

Vitamin D3 is a fat-soluble vitamin that can be obtained from certain foods like fatty fish, fortified dairy products, and through exposure to sunlight. However, many people may have inadequate levels of vitamin D due to limited sun exposure or dietary preferences, which is where supplements like those from Thorne Research can be beneficial.

Vitamin D is crucial for the body's absorption and utilization of calcium, a mineral that's essential for strong bones and teeth. It also supports immune system function and has been linked to overall well-being.Thorne Research likely offers Vitamin D3 supplements in varying dosages to cater to individual needs.

Consumers interested in improving their vitamin D levels or addressing specific health concerns related to calcium, minerals, and overall health may consider Thorne Research Vitamin D3 supplements as part of their dietary regimen, under the guidance of a healthcare professional.

Question: What is the carrier oil used
Answer: I used the case for a few days prior to installing the screen protector. I do not see any difference in tightness prior to or after installing the screen protector. The screen protector does not interfere with the case, so that's probably why there is no difference in case tightness.

User questions & answers

Question: how many servings per container
Answer: It is possible that certain bioflavonoids can affect the absorption of iron because they bind iron, although bioflavonoids also play a role in iron homeostasis in the body. If you are anemic or you are requiring iron supplementation, and you are concerned about the bioflavonoid component, then you should consider using Thorne's Ascorbic Acid instead, our product that provides vitamin C without the addition of bioflavonoids. For a more comprehensive solution to supplementing iron, Thorne’s Ferrasorb contains iron, activated folate, vitamins B6 and B12, as well as vitamin C for optimization of iron absorption.
Question: are the capsules tiny like before the label change
Answer: It is right on the label itself
Question: How does this brand and supplement compare to Pure Encapsulations vit D
Answer: And what does "pharmaceutical grade" mean? I imagine there are guidelines if one is going to manufacture ingestible products i.e, no arsenic or hemlock. These vitamins are quite tasty and, I assume, contribute to my well-being.
Question: How much alpha-tocopheral is in with the vitamin d3? And why is there vitamin e in the capsule
Answer: No, this does not act as a laxative. It's a calcium supplement.

User questions & answers

Question: Is it shipped in plastic seal around top or just in small bubble plastic bag
Answer: Thorne Research manufactures their products in their new state-of-the-art manufacturing facility in South Carolina, USA. Thorne tells us: "Thorne Research sources its ingredients from around the world, including China. However, what is much more important than the country of origin of an ingredient is the testing that is done on that ingredient when it is received by the manufacturer. Thorne Research does not rely on the Certificate of Origin from an ingredient supplier. Instead, Thorne Research tests every single ingredient in our own in-house laboratory, regardless of the ingredient's country of origin, to verify the ingredient's identification, purity, and quality. That's what makes Thorne a better brand."
Question: Is it okay to order this during the summer when it will be exposed to heat during transit
Answer: Because it is proprietary and confidential business information, Thorne does not disclose the country of origin of its raw materials. Thorne tells us: "Thorne Research sources its ingredients from around the world, including China. However, what is much more important than the country of origin of an ingredient is the testing that is done on that ingredient when it is received by the manufacturer.

Question: ingredients
Answer: Silicon dioxide is silica mined from the earth reacted with oxygen – two of the earth’s most abundant minerals. Silicon dioxide is ubiquitous in nature and found in drinking water and many foods, especially those high in fiber. The U.S. Food and Drug Administration has designated silicon dioxide to be a safe food additive.
Question: Have you tested your 25 hydroxy vitamin D since taking this supplement
Answer: The vitamin C is synthesized, which means it was converted and purified from other natural starting materials, in this case glucose. After Thorne receives the vitamin C, it is tested to confirm its identity, purity, and potency. It is also tested for the presence of potential contaminants. Because there is no remnant of the original starting source material, the resulting vitamin C is molecularly identical to vitamin C that might have been naturally derived.

User questions & answers

Question: What about the silicone dioxide in your vitamin k as mentioned in the one negative review you received
Answer: In response to another question: "Both vitamin K2 supplements are nearly completely absorbed, with peak serum concentration at 2 hours for MK-4 and 4 hours for MK-7 after intake. Originally, the most compelling research was on high-dose MK4. More recently, some interesting MK7 research has been conducted and published. Therefore, Thorne is working on a combination product that should be available in 2016. Any studies looking at increased bone density are typically long range studies."
Question: What is another high dose vitamin K brand without excessive silicon dioxide
Answer: Both vitamin K2 supplements are nearly completely absorbed, with peak serum concentration at 2 hours for MK-4 and 4 hours for MK-7 after intake. Originally, the most compelling research was on high-dose MK4. More recently, some interesting MK7 research has been conducted and published. Therefore, Thorne is working on a combination product that should be available in 2016. Any studies looking at increased bone density are typically long range studies.
Question: what is the source of the K
Answer: I noticed a large discrepancy in the two answers already given, so I'll try to clarify the confusions. The label states (not "drops" but "servings") "Servings Per Container: 80" and also states "Serving Size: Fifteen Drops" and "Fifteen Drops Contain: Vitamin K (as Vitamin K2 Menatetrenone) 15mg". So at the rate of 45mg/day, the 1200 drops/bottle would indeed last 26+ days or about a month; however the math at 5 drops/day would last 240 days or about 8 months. While some may use as little as 1 or 2 mg/day, at my actual use rate of 7drops/day a bottle has consistently lasted just under 6 months which fits with the math that works out to 171+ servings. Hope this helps!
Question: Why is there so much silicone dioxide in each capsule? I would not expect this from Thorne
Answer: Expiration date will depend on which seller you choose at checkout and which lot they are shipping. If you choose iServe Products, all of our items are stored and shipped from Amazon fulfillment centers. Amazon has strict rules about expiration dates, so you shouldn't receive a close-dated product. If you do, please contact us!

Question: Is this a wholefood supplement or do they use synthetic vitamins/minerals? Thanks
Answer: The K2 is MK4.
Question: ingredients
Answer: Yes it contains 200 mcg of Selenium per day, which is a lot! On the Australian multivitamin tablets I have taken in the past, there is a warning on the bottle that says "This product contains Selenium which is toxic in high doses. A daily dose of 150 Micrograms for adults of selenium from dietary supplements should not be exceeded." Although I have only been taking one Basic Nutrient tablet per day, I will stop taking this formula once I have finished this bottle as I feel it contains too much Selenium.

Answer: I don't know why they have to have such mega doses. I have been taking this for 2 months and I have only been having 1 tablet per day (half the recommended daily dosage) and although I feel good and have more energy I am really worried about the risks of taking this product long term so I will stop taking it once I finish this bottle. I wonder if it was the Selenium in it that caused your liver enzymes to get high? This product contains way too much selenium in my opinion. It is a shame because if they reduced some of the doses of the ingredients and removed the Chromium all together I would continue taking it. I really like Thorne Research, I think they make good products but this one is just too much. You really have to be careful when taking vitamins, too much of a good thing can possibly be harmful.

User questions & answers

Question: Is this certified vegan
Answer: Thorne’s Stress B-Complex is considered vegan.
Question: My concern is that of the review "pyridoxine form of b6 is toxic and should be changed to all p5p or pyridoxal". does anyone else have any thoughts
Answer: I did not hear of that, but this was recommended by a pharmacist.
Question: I have read that sublingual vit b´s are better absrorved and these are not, so I wonder if these have or not the same bioavailability as the others
Answer: Although this is something many people want to know, the research performed to date does not support the conclusion that sublingual forms of certain vitamins are better absorbed than encapsulated forms. The research does support the conclusion that both the capsule form and the sublingual form (usually vitamin B12) are efficiently absorbed and do correct deficiencies. Nutrients in capsule form are absorbed similarly to nutrients from food; i.e., they are broken down and absorbed in the intestines. In addition, Thorne’s Stress B Complex includes several of the most optimally absorbed forms of the B vitamins.
Question: What's the source of B12? I get nervous about "vegetarian" anything when it comes to B
Answer: Methylcobalamin is equivalent physiologically to vitamin B12, and can be used to prevent or treat pathology arising from a lack of vitamin B12 (vitamin B12 deficiency), such as pernicious anemia.Methylcobalamin is also used in the treatment of peripheral neuropathy, diabetic neuropathy, and as a preliminary treatment for amyotrophic lateral sclerosis.

Question: Does this contain gluten

Question: What's the difference between this and the stress b complex they also sell
Answer: Look more closely at the label ; folate is an abbreviation for it's full description. On label form it says 'L-Methletetrahydrofolate' (whew, hard to type that), plus lots of other longer words following containing 'folate' within them. Hope this helps!

User questions & answers

Question: Does this currently come in new packaging? thnx
Answer: I am reading the label now and it does not list the amount of silicon dioxide provided. My doctor recommended this particular vitamin K product to help me fight osteoporosis. According to my reference book (Prescriptions For Nutritional Healing), silicon dioxide is important in the prevention of Alzheimer's disease and osteoporosis. It stimulates the immune system and inhibits the aging process in tissues. So, elderly people need larger amounts. I have been using it for 4 years and have no side effects, if there are any.
Question: What country is this product made in
Answer: The vitamin K (K1 and K2) in Thorne's 3-K Complete is from natural source geraniol, a monoterpenoid and an alcohol derived from rose oil, palmarosa oil, and citronella oil.
Question: Is the MK7 in this product sourced from soy
Answer: The amount of silicon dioxide in Thorne’s 3-K Complete is less than 2 percent of the total formula and does not affect the quality, efficacy, or safety of the finished product. Silicon dioxide is used to minimize moisture content and to help powders flow into capsules. Although silicon is sometimes confused with silicone (which is a synthetic compound), there is no chemical similarity between these two substances. Silicon dioxide is a naturally-occurring compound that contains silicon, a mineral that is ubiquitous in nature and found in many foods, especially those high in fiber, and, because it is necessary for bone growth and maturation, it is also often added to nutritional supplements designed for bone support.
Question: are these vegan
Answer: My last two bottles had expiration dates about a year out.Good stuff--helped repair my teeth--good luck.
