My DNA shows my ancestors came across the land bridge o Alaska. My family lacks the gene to convert carotenoids to Vit A . However fish, whale blubber, wild game all have Vit A. When I when vegetarian for 10 years, I developed Drusen deposits that are pre macular degeneration. Since the 5 years I returned to being an omnivore, I have no macular degeneration progression. So yes we may need either real retinoids acid or eating healthy animal fats. Sandra P. MD

I am so impressed that this physician takes time to answer comments. Brabo to thid M.D.

Thank you for all the research you do on these tough scary reports that continue to come out with “ one size fits all!” It makes a lot of sense after you explain things the way you do.

I had my DNA tested about 5 years ago and it clearly stated, in the evaluation and advice, that I needed Vitamin A from animal sources as there was a problem converting beta carotene to retinol.

“How do you do this? …. It’s impossible!” Love your knowledge and sense of humor!! Such clear information and well thought out discussion! I’m now a subscriber!

Thank You. Most informative and balanced which helps the listener to make an informed choice.

I am on long term low dose prednisone for PMR, so I’m trying to get ahead of osteoporosis. One thing I discovered was that after 3 years I started having serious wound healing issues. As in simple open wounds were taking months to heal. I discovered that using retinol vitamin A applied to the wounds and taking 10,000 iu 2x a week finally had my wounds healing and I’ve not had healing issues since. Now I’m concerned about how to keep my wounds healing normally without increasing chance of hip fractures. I also have serious nutrient absorbing issues, which may contribute. I love these videos that give us the info to make the right decisions fir our health.

A very good analysis. We really have to be careful of studies and the results. Thank you for your sensible conclusions!

thank you. Obviously those if us who are using Medicare as Insurance are not receiving proper information. I have only seen my Endocrinologist 2 twice in 2 years. Everything is based on DEXA scans. They just prescribe and no real follow up. I just received my 1st RECLAST infusion. I believe it will be my LAST. I have been using all the "supplements" that you have suggested. My next goal is to ramp up my muscle mass.

Dr Lucas Can you recommend an acceptable protein powder? Your opinion is valued. Thank you!!

Drunk people tend to fall more often. Sobriety is fall prevention.

Vitamin A has always been a problem if you take it as a supplement, whether beta carotene or retinol. Best to always get nutrients in their most natural form.

Thank you for the information. 🙂

Vegan bias is a huge thing.. and I was a follower for over 15 years. Now I’m paying the price. I’m back on animal protein and other protein big time..and very low carb… no added sugar or alcohol. When the study on hip fractures was released the information was diluted and the smoke and mirrors… I should have dug deep but… Well now I’m thinner, more muscle from the weights and protein(I can get up and down off the floor easily which I could not do AT ALL a year ago). I want to know if you recommend a certain protein powder? I like it for an easy and light breakfast.. after morning exercise 🎉 ( and cold in this brutal heat)-and I try to get at least 30 gr of protein at each meal. Any help greatly appreciated. Do you recommend whey or plant protein powder.. or any at all? (Video idea?🤷‍♀️😏) Thanks Dr Lucas!

This is not on the topic of Vitamin A, but I am wondering if you have heard of, or have an opinion about using Bone Morphogenic Proteins for bone health. I have samples of a specific product from a specific manufacturer that I am considering trying. The patented substance is described as ""Partially hydrolyzed collagen and its associated proteins including Bone Morphogenetic Proteins." Thank you for the wonderful education on osteoporosis!

Awesome ‼️💯

I love-love-love your video's, but please eliminate the music in the background. It is very distracting and takes away from your important content. thanks

Should I stop eating sweet potatoes, carrots, parsnips and all Vitamin A vegetables and fruits? I have a very slight chance of fracture but don’t plan on falling. I work full time in finance and before I got covid in 2020/21, I earned an MBA with double finance and analytics concentrations and was running/walking 5 miles a day with weights. I am over 65 with no other health issues. I think continuing my healthy lifestyle will continue as it has thus far. Studies are usually geared to what the people doing the studies want the results to be. I have never eaten much and that can lead to bone loss too.

4:37 the 95% confidence interval includes the 1.0 RR line most of the time. What does this graph tells you then? Almost nothing. Could mean for you that a low or high level of retinol does nothing for YOUR risk. If it's not data from an interventional study, it doesn't tell you anything about your personal risk anyway.

Thank you. There is so much bs on the web it’s hard to know what’s correct

I scheduled a meeting at 12:00 today for counseling. No one called me.

On point evaluation of inadequate data. One might as well say stepping outside is associated with increased risk of death due to solar radiation, risk of accidents or violence, falls, etc. The list of confounding data is immense here and conclusions that were drawn are far from actionable proof.

Thanks! Objective and Useful

Probably a stupid question, but does this relate to using Tretinoin cream, i.e., 0.05%, on face & neck?!?

Subscribed today Technical A lot to think about

12:05 I think one need to say that Retinoic acid and 1,25-dihydroxyvitamin D3 are not the Vitamin A you get from animal food or from your usual D3 pills. These are already metabolites of what you eat. If they inject mice with those, that may have completely different results from eating real food.

I have many things that matter but I have two artificial hips, so I’m not worried about my hips but I am worried about the rest of me. I left a message on another video. I do have osteoporosis I have LEMS and I have RA. I’m 76 I’m trying to figure out what to do I may end up on probably I don’t know but I have to check my levels again so we will see. But I think you for your information because you have a lot of good stuff. Thank you.

Hi Doctor. I have high cholesterol and eat a whole egg and two egg whites. Is the retinol in eggs in the yolk, the white or both? Thank you for your answer.

I see a lot of supplements have K2 and K1. I can t take K1 with low dosage aspirin I was told. I’ve was told to take calcium citrate for yrs without k2. Now I’m told if you didn’t take K2 with calcium you get calcified arteries , which I now have.

Hi my name is Annemarie I have spinal stenosis, my muscles contract, always holding my muscles tight, my neck muscles contracting, them ! Compression pain is also terrible 😢, thank you???

I mentioned this on another video, but it might be good to try putting your camera on manual focus, so it's locked on your face and doesn't keep searching.

20:55 Is there a good multi vitamin and mineral supplement that is good?

Hi Dr Doug, thanks for the useful content. What about retinoid and retinol used for skin care eg tretinoin creams and adapalene? Would these be absorbed into the body to sufficiently affect bone density?

What’s the verdict on taking Cod Liver oil?

What about retinol a for your face? I have osteoporosis should I avoid that

My eye doctor has suggested a supplement that contains significant levels of vitamin A to combat dry eyes. In combo with my multivitamin it results in about 1650 mcg daily. Is that amount a potential problem!!??

How much beta carotene can I safely take in mcg ? I have two supplements totaling 3750 mcg. Is this a safe amount?

I DRINK CARROUT JUICE 2 TIMES A WEEK , SO I DONT HAVE TO DO IT ANY MORE?

I have read in a few places recently that since fat soluble vitamins compete for absorption, vitamin D and K should be taken separately. Any thoughts on that? THANK YOU :-))))

If you had a Dexa after a broken femur and anterior hip replacement three weeks out after heavy blood loss lowered hermaticrit also BP. Could that affect your Dexa?

Heres the thing i want to know about all these studies. Did all the people taking vitamin a go skiiing cos they felt amazing. As far as i know beta carotine is banned in europe now ..in the 80s it was a big scandle because people took it for tanjing in high doses (to tirn orange) and now if its not banned ive never seen it and most people know beta carotine is bad for you from that scandle.

Norwegian Cod liver oil safe?? All animal sourced vit A is safe, is this correct?? Cod liver oil, egg yolk, liver??

I have a question. How does retin A for the face affect bone loss?

Who takes retinol? We use it on our skin!

Too complicated. Take retinol or not?

Hi Dr Doug I have recently found your videos helpful and wonder could you tell the starting point for treatment for a osteoporosis diagnosis with a TBS 1.189 at 69 yrs after hip fracture but still with good general physical health. My doctor insists I go straight on drugs. I have longevity in my family. Thank you

How much beef liver should you eat? One way to look at this: If you eat half a cow in total per year, maybe you can/should eat also about half a cow liver per year. If half a cow liver is at least 2,5kg, then you can eat 50g of beef liver per week. Which would be 7000-9000 IE per week and 1000 IE per day. Sounds reasonable.

You cannot just test one vitamin and leave all the other Vitamins and minerals out. They work together. School medicine does not know much about nutrition, vitamins and minerals, if they would they would know that the body can only stay healthy when they are properly supplied with all vitamins and minerals etc.

Does your program work within a vegan framework?

So cod liver may not be good for you?

How about eye health 😮

im juicing every day and including 8 large carrots..does anyone know if this is too much? im vegetarian

The study is biased as many studies are...I take it with a grain of salt...

Red Flag . What was the age of the test group?

What about Cod Liver Oil? I take this every day? Is this giving me too much?

I broke the stem of my femur is that a hip fracture?

confusing and too long. you lost me
