Podcast: B12 and Vitamin D Supplements

[@jamessullenriot]

My key ... Get 2 blood tests per year. Insist B12 get tested and pay the extra $$ to get D levels tests (most places its not included) No point in wondering what levels are when you can know for sure

[@adastraedu]

Unfortunately there is a huge variance in vitamin D test results so you cannot know for sure that easily.

[@MqKosmos]

Yup. Just watched his video on it again. Depending on where you send your sample you get vastly different results back. Plus vitD goes up in an instant when you are exposed to sun enough or take it via diet. Really the worst way to spend your money at blood tests

[@azlizzie]

I bike in the Arizona desert. I wear sunblock and layers to protect... I was severely vitamin d deficient. Go figure...

[@SherryEllesson]

That actually makes sense, given your sunblock and clothing block the rays from actually reaching your skin.

Unless you have more of a chance for skin cancer, be less protective. Let the sun penetrate your skin.

Very interesting info about winter levels of Vit D. There is an interesting article in JCEM, Vitamin D Stored in Fat Tissue During a 5-Year Intervention Affects Serum 25-Hydroxyvitamin D Levels the Following Year, for anyone who wants to follow the science.

[@ronaldparvanian6949]

Watch the very recent interview with Dr. Michael Hollis Phd. by Dr. Berg. D3 must be supplemented daily to keep levels up despite being fat soluble. This is why studies where mega doses of D3 given monthly or even weekly fail to keep consistent therapeutic levels. I suspect such studies were designed to fail.

In this video you said for B12 2000 a week but in previous posts, you said if 65 and over, take 1000 per day. Is this still correct?

[@michaelwilkinson5097]

As we age, our ability to absorb certain vitamins including B12 lessens. So we have to increase the doses we take

[@andrewcool8774]

can I take all my vitamines including d3 at night? Or do you have to take it in the morning and does oats block the d3? I take them at night nog

[@economicdevelopmentplannin8715]

D is only taken in mornings because it is a hormone that can keep you up at night. If skin is making it from sunlight, your body thinks it's day time 😊

[@Marr033]

Oats dont block any d vitamin. You should eat a fat source with your d if its not in a liquid form (add coconut yogurt, peanut butter, seeds like ground chia/flax etc)

[@3dinfinitespace220]

I'm sure humans natural source for B12, came from the water. As many animals pee and poop in the water and it's filled with bacteria. Nowadays it's filtered out, as I'm sure goes for many other essential nutrients, like iodine, which is also being fortified in bread, through salt. (Not organic bread, though, at least not in my country.) Of which I both believe, would be more beneficial, if added back to the water supply.

[@guyfawkes5012]

I recently found out that high doses of Vitamin B12 can cause tingling sensation in fingers & toes. (2000 mcg per week in my case) Made me paranoid even though I already suspected it, until i stumbled over it being mentioned as a side effect on the mayo clinic website. Symptoms persist for couple of days.

[@tnijoo5109]

Wow. That’s not even that much! 😮 good tip. I will be more careful to not get too much. Thank you.

[@tinyjungle_]

Interesting because many people might consider the tingling a potential deficiency and take more B12 because of it

[@misterx3188]

Interesting. I once applied over 5,000 mcg subcutanely (i.e., with massively higher bioavailability) and didn't have that. Seems like this may happen in some patients, but not all.

[@kristingoettlicher3503]

@W P I really wonder if low magnesium and/or potassium is a problem for myself. Didn't know that can cause the neuropathy. Interesting.

[@laynieree4536]

B6 definitely causes peripheral neuropathy and because toxicity symptoms are the same as deficiency, people end up increasing their dose.

[@metaphysicalArtist]

I would like a video about the nutrition value that a silverback gorilla eats per day, and they eat 25kg of green plants. So what is the daily vitamin, mineral, amino, omega and fiber they consume?

[@metaphysicalArtist]

Silverback gorillas are herbivores, and their diet mainly consists of green plants, fruits, and leaves. They eat about 25kg of vegetation per day, which provides them with a wide range of vitamins, minerals, amino acids, omega fatty acids, and fiber. Here is a breakdown of the daily nutrition value that a silverback gorilla consumes: Vitamins: Vitamin C: about 400 mg Vitamin A: about 7000 IU Vitamin B6: about 0.5 mg Folate: about 400 mcg Minerals: Potassium: about 3500 mg Magnesium: about 450 mg Calcium: about 400 mg Iron: about 6 mg Zinc: about 7 mg Amino acids: Silverback gorillas consume all the essential amino acids in sufficient amounts through their plant-based diet. Omega fatty acids: Silverback gorillas consume alpha-linolenic acid (ALA), which is a type of omega-3 fatty acid, in their diet. Fiber: Silverback gorillas consume a high amount of dietary fiber from their plant-based diet, which aids in digestion and provides other health benefits. It's important to note that the exact nutrition value can vary depending on the specific plants that the gorilla consumes, as well as other factors such as age, sex, and activity level. - ChatGPT Mar 14 Version

[@Spanede]

Great question, I want the answer too

[@Jeffs60]

@@metaphysicalArtist And the silverback gorilla lives about 40 years, has to spend 16 hours all day eating and still has to eat their own poop to make up for the low nutrient diet, and can't even throw a baseball anywhere as fast or strong as a human who is 1/3 of their weight. They also have a typical total cholesterol level of about 240 mg/dL. Is this the life you want to emulate?

[@metaphysicalArtist]

@@Jeffs60 The purpose for my comment is the myth that Vegans compared to Silverbacks, believe they get a full nutrition package eating so little greens.

[@Jeffs60]

[@contact2001]

[@bettymaugeri7316]

Can I take calcium - Dr wants me on prescription drugs for osteoporosis - high risk for fracture

[@davidgifford8112]

Calcium is only part of the problem. If you are consuming a diet rich in leafy greens you should be getting plenty of calcium. Getting it into the bones maybe the problem, vitamin K2 helps with that, then there is collagen to consider, which is a major component of the bone matrix.

[@awizenwoman]

See Dr John Campbell's channel for videos on optimal vitamin D levels. I am always referring him and others to your channel, but am usually ignored. Now am referring you to his channel regarding vitamin D (2/3) +K2+zinc. Daily, I take vegan D3 3,000 iu + vegan D2 600 iu + zinc + K2. K2 prevents calcium being stored in the wrong place due to high D3 intake.

He's trying to tell you that if you get tingling in your feet and fingers you shouldn't worry about it just because the nerves are so long. Big deal. It doesn't matter that you might be on your death bed.

In 2011, we launched the acclaimed website you see today and now rely on individual donors to continue our work and keep the site alive.

@@Goodmorning1221- It depends. A lot of research is done at universities or hospitals which is funded by grants or the institution itself. Some research is funded by industry. Those have to be curated carefully as the study can be crafted with a particular outcome in mind. NutritionFacts doesn't do their own studies as far as I am aware. Their job is to read and review all the English-language studies that are published. They look for flaws and present only the best studies in the videos and books.

I have lived successfully with diabetes since 1998. I have not spent a night in the hospital yet. My last A1C was so good it would not even get you a diagnosis of "Pre-diabetes". I've read almost every book in the library about diabetes including the books by the vegan activist Dr Barnard and the 2 young guys running Mastering Diabetes. I can tell you that Dr Bernstein the 88 year old MEDICAL doctor and type ONE diabetic is right when he says diabetics can achieve normal glucose levels with eating mostly ANIMAL protein with vegetables.
