Second Vitamin C HD Study of 10 dogs
2009 - 2014
Mean average score = 3.5

The average total score for Golden Retrievers tested in the UK, NZ, and Australia is between 12 and 15.  The Lorgair Kennel study results were substantially lower than the average.

This Mini-Study is using a diet of 900 mg daily of Neo-Life NeoLife Threshold (Sustained or Super) Vitamin C + Dr Kruger Joint / Muscle formula for dogs who's adult weight is between 25 kg and 35 kg (Large Dogs).  The NeoLife Vitamin C is to increase the "paltry" amount of ascorbic acid dogs produce naturally in their liver.  The Dr Kruger Joint / Muscle formula is to ensure the dogs get ALL the nutrients they need in their diet.  The Vitamin C forms a honeycomb that allows the nutrients to absorb into the joints.

Some dogs had raw meats added to the diet which progressed from 1/3 raw & 2/3 Orijen up to 6 months; then 2/3 raw & 1/3 Orijen up to 12 months; and then all raw from 1 year onward.   All Dams were given 900 mg Neo-Life Threshold (Sustained or Super) Vitamin C throughout pregnancy and puppies were started on 23 mg of Neo-Life Neo-C (All-C) at 3 weeks of age and progressed to 450 mg by 5-weeks of age.  At either 8-weeks or 12-weeks the puppies were increased to 900 mg daily.  The results have been extremely satisfying and consistent within a narrow range of totals between 1 and 7.  Dogs who's weight in adulthood is less than 25 kg should use 1/2 the amount (Small and Medium size dogs).  Giant breed dogs should try 1800 mg daily and breeders should adjust the amount based on results.  See guideline down page.

What has become evident is that active large breed dogs whose adult weight will be between 25 kg and 35 kg need 900 mg daily of Neo-Life Threshold (Sustained or Super) Vitamin C to at least 18 months of age to produce consistently good hip results.   For extreme stress conditions such as active/frequent game retrieval, Husky sled driving, or emotional stress like frequent and ongoing earthquakes, may require larger dosages of Vitamin C.  The 900 mg of Neo-Life Threshold Vitamin C is 85% less than the amount of sodium ascorbate that Dr Belfield used in his studies.

Chronic Subclinical Scurvy:  Dr Belfield had this to say back in 1982 -  "Stress is the scourge of both man and dog.  Stress undermines resistance to disease and germs in part by depleting the body's stores of water-soluble vitamins, namely vitamin C and the B complex group."  (Stress can be both physical and/or emotional)   "For the size of the German Shepherd, Great Dane, Saint Bernard, and other large dogs, canine liver production of vitamin C is paltry.  This poor production, along with the nonstop stress, results in chronic subclinical scurvy.  The animal may not lapse into terminal scurvy but he will often become ill with some of the symptoms.  Hypertrophic osteodystrophy (HOD) ... is one example.  And so is hip dysplasia.   Both conditions are related to deficient vitamin C and poor collagen."

"The big-breed pup has an extraordinary need for large amounts of vitamin C.  The vitamin is needed in laying down the collagen.  He needs strong ligaments and tendons to hold bones and a heavy muscle mass in place.  He gets no vitamin C in his food.  If his liver doesn't produce enough, the animal is at risk, and from the worldwide incidence of hip dysplasia, it seems obvious that the liver of the domesticated dog is not up to the task."  Pages 190-191 How To Have A Healthier Dog, The Benefits of Vitamins and Minerals for Your Dog's Life Cycles.

For those who wish to try using Neo-Life Vitamin C to reduce the risk of hip dysplasia in their puppies there a couple of facts that have been realised and need to be taken into consideration.  

  1. The adult weight of the dog is the guide as to how much Neo-Life Vitamin C needs to be administered.  I used 900 mg for Golden Retrievers where the girls are normally around 26 to 28 kg as adults and the males are around 35 kg.  If the adult weight is around 35 kg and above, then you need to double the amount of Neo-Life Vitamin C to achieve scores that are total 5 or less.  Breeders with dogs 35kg or more have found that using only 900 mg of the Neo-Life Vitamin C return scores of around total 10.  So if you want really low hip scores, you need to use a proper amount of the Neo-Life Vitamin C.  Smaller dogs who's weight will be less than 25kg should be able to return good scores using less than the 900 mg of Neo-Life Vitamin C.  As a breeder or puppy owner, you will need to run your own studies to find the right dosage for your size dog and lines that you are breeding.  The activity level of the dog has a lot to do with the dosage as well -- the more active the dog, the more Neo-Life Vitamin C they need because they will be burning more up.
  2. The other discovery that has been made by a couple of breeders in Australia is that those dogs living in high temperature zones appear to need twice the recommended amount and need to be hydrated.  There is no further help on this subject for the hot areas of the Northern Territory and Queensland at this time -- studies are still being conducted to find the right dosage for high temperature zones.
  3. As discussed above, really active dogs will need more Neo-Life Vitamin C because their bodies will use a great deal more.  Also dogs in high stress situations like active earthquake zones.  Although one Golden Retriever scored well on the normal 900 mg daily living in the Red Zone of Christchurch, there is no guarantee that all dogs under this kind of stress will do well on a normal dosage of Neo-Life Vitamin C.
  4. Those breeders who have experimented using the Neo-Life Vitamin C have, for the most part, achieved good hip scores for their dogs and these include many different breeds of dogs.  Those that have found the total average to be around 10, have either used less than the recommended amount; lived in high temperature areas; or have found their dogs weight to be a differential factor in using the Neo-Life Vitamin C as their dog's weight was not in the 25kg to 35 kg range and used 900 mg daily.  The Neo-Life Vitamin C will work, but must be given in a large enough dosage and daily without fail.

The difference using Neo-Life Vitamin C:Studies by Dr Belfield and another scientific study done in Southern California, found that pure ascorbic acid (like you use in canning) and calcium ascorbate are both “duds” and “a waste of time and money” – and not adequate sources of vitamin C.  Ester-C contains calcium that is not good for the joints and can lead to the formation of crystals and stones in the dogs.  I had pretty much come to the conclusion back in 2006 that the GNDL Vitamin C was special and powerful from my own use of it.  Belfield makes his own vitamin C formulas from sodium ascorbate, but the vitamin C levels are too high to import into NZ.After years of using the Neo-Life Vitamin C products, for both the dogs and personally, it is clear that Neo-Life has an extremely high absorption rate into the body cells.  The Neo-Life Vitamin C formulas are molecularly-natural made from fruits and vegetables and produced without any chemicals.  100 mg of the Neo-C (All-C) is the equivalent of eating 4 small oranges.  900 mg of Neo-Life Threshold Vitamin C is the equivalent of eating 36 small oranges.  People who's stomach are not able to tolerate normal Vitamin C, report that they have no problems with the Neo-Life Vitamin C and are amazed at how fast it eliminates colds and flu.  Because Vitamin C is water soluble and doesn't stay in the body, it can be taken to bowel tolerance level.  The benefit for the dogs is that it synthesis' into collagen needed for the joints, ligaments, and muscle tissue extremely well.  The final study proved that using 900 mg daily of the Neo-Life Threshold Vitamin C, the dogs only needed 15% of the amount Dr Belfield recommends be used to return great results. 

Ordering Neo-Life NeoLife Vitamin C.  900 mg of Neo-Life Threshold Vitamin C is 85% less than what Dr Belfield recommends to achieve the same results with sodium ascorbate given at 6,000 mg daily. 
Vitamin C is water soluble and other types of Vitamin C go through the body in 2 hours.  Neo-Life Vitamin C formulas stay in the body longer than other types of Vitamin C -- 4 to 8 hours.
Although Neo-Life products are not available in stores, they can be sourced through distributors in over 60 countries world-wide.   If you have an interest in becoming a Neo-Life Distributor, I can sign you up as a distributor and save you 25% on Neo-Life orders, drop Sy an email at  To buy the Neo-Life within New Zealand  go to .  If you would prefer to purchase the products at retail price and live outside New Zealand, send me an email and I will provide the name(s) of a distributor in your country or I can send you an application form to become a distributor.  You do not have to stock any products to be a distributor.  The Dr Kruger products can be sourced from (US and Canada), (Within NZ), and (Europe and UK).  Note of clarity - the Neo-Life powder Vit C is no longer available.  The Neo-C is the same All C and Threshold Vit C is the same as Sustained Release Vit C.  Check the level of mg per tablet as they will vary in different parts of the world according to country regulations.  An update article on this subject ran in the April 2011 NZ Dog World.

In the "Library" you will find a couple of articles relating to the reduction or elimination of the ability of some dogs to produce collagen after vaccinations or anti-biotic usage.  Also in the library are the articles appearing in NZ Dog World on this subject.  Have a read and then decide for yourself if it might be beneficial in your instance to supplement vitamin C for your dog.
   The Neo-Life difference in Vitamin C  Threshold (Sustained or Super) Vitamin C maintains sustained release of nutrients for up to six full hours but is best not chewed when taken.Neo-C contains the following in the form of chewable (230 mg ascorbic acid per tablet) or powder (507 mg ascorbic acid per teaspoon).  Neo-Plex Concentrate has all the naturally occurring elements in whole oranges (juice vitamin C, flavedo, mesocarp, endocarp, protopectins, p-factors, and flavonoids) except water, to enhance absorption and utilisation of vitamin C.Vitamin C is an essential nutrient that cannot be stored in the body; it must be consumed every day to maintain good health.  Current research verifies the importance of vitamin C as a water soluble antioxidant.  Vitamin C is also necessary for the body's synthesis of collagen (part of the cellular "cement" that holds us together and provides structure for our muscles, bones, and vascular system).  In addition, vitamin C assists the absorption of dietary iron.

of Vitamin C for Dogs - Neo-Life Vitamin C suggested dosages
.  Please note that in Sy Guth's early mini study of Golden Retriever puppies, she used 460 mg daily of Neo-Life vitamin C to effect a positive change in the outcome of her large breed puppies.  Some dogs are better producers of vitamin C than others and some dogs are more active and use high amounts of Vitamin C daily.  In Sy's later study she has used 900 mg Neo-Life Threshold (Sustained or Super) Vitamin C for large breed active dogs and found the results to be consistently good.  In a study of 104 dogs the range for producing their own vitamin C was "from .02 mg to .84 mg for each 100 cubic centimetres of blood." (Belfield) It's difficult to know how much vitamin C a dog produces individually, so we recommend the following minimum Neo-Life supplementation for puppies:

Size Dog - daily doseage 3 weeks to 5 weeks 5 weeks to 12 weeks 12 weeks to 18 months
Small dogs Start with 225 mg per litter and work up to 225 mg per puppy at 5 weeks of age 225 mg daily 220 mg daily
Medium Dogs Start with 450 mg per litter and work up to 450 mg per puppy at 5 weeks of age 450 mg daily 450 mg daily
Large Dogs Start with 450 mg per litter and work up to 450 mg per puppy at 5 weeks of age 450 mg daily 900 mg daily
Giant Dogs Start with 675 mg per litter and work up to 675 mg per puppy at 5 weeks of age 675 daily 1800 mg daily

For pregnant bitches
, we suggest the same dosage as for puppies from  8 weeks to 18 months.  The daily addition of Vitamin C may reduce whelp times up to 50%.  The addition of daily Vitamin E during pregnancy may help to strengthen the muscles needed for contraction and reduce the need for oxytocin or other contraction inducements during whelp.  Be sure to use the Dr Kruger Puppy and Pregnancy formula starting the day the bitch comes in heat -- the girls need some inflammation in their womb for the embryos to adhere to the walls.  The Dr Kruger Joint / Muscle formula contains 3 herbs that are anti-inflammatory.  Once the girls have whelped, then the Healthy Joint formula is excellent for reducing the inflammation in the womb and increases milk flow substantially.  If the bitch is not normally on a daily dosage of Dr Kruger formula, we suggest that the formula be started at least 3 months prior to the bitch's heat to ensure she is in optimum health.

Using Sodium Ascorbate Vitamin C.  Those who have compared using the sodium ascorbate to the Neo-Life Vitamin C, they have found it more cost effective to use the Neo-Life Vitamin C.  For a Large breed active dog you need 6,000 mg daily of sodium ascorbate compared to only 900 mg of the Neo-Life Threshold Vitamin C.  Neo-Life requires 85% less to be effective.The only synthetic vitamin C that has been shown by Dr Belfield and a LA study to lower the risk of HD is sodium ascorbate.  Dr Belfield gives the doses need for this type of synthetic vitamin C as:  Dr Belfield in his book, How To Have A Healtheir Dog, The Benefits of Vitamins and Minerals for Your Dog's Life Cycles, published in 1981, recommends the following doses of vitamin C depending on activity level of the dog:
Small Dogs - 500 to 1,500 mg daily
Medium Dogs - 1,500 to 3,000 mg daily
Large Dogs - 3,000 to 6,000 mg daily
Giant Dogs - 6,000 to 7.500 mg daily
Puppies Large Breed - first 4 months - 500 to 1,000 mg daily
Puppies Large Breed - 4 months to adult - increasing gradually - 1,000 to 3,000 mg daily

Dr Billinghurst's recommended doses with the BARF diet for vitamin C from his book:
"Vitamin C, the stress vitamin, may be supplemented at up to 100 mg per LB (200 mg per KG) of pet per day, or even more up to bowel tolerance in conditions of extreme stress."
Vitamin C is recommended by Dr Ian Billinghurst, veterinarian, author of the BARF diet; Dr. Wendell O. Belfield, veterinarian, author of several articles on CDC, and by Sylvia Hammarstrom, author of Vitamin C and Hip Dysplasia and long time breeder of Giant Schnauzers, German Shepards, and other large breed dogs.  Sylvia has bred over 1,000 champion dogs.Breeders needing a regular supplyIf you are a breeder and think you will be ordering Neo-Life vitamin C on a fairly regular basis, you may wish to look into becoming a distributor.  Neo-Life is a multi-level marketing company started in 1958 in the USA.  Distributors receive up to 25% discount on purchases and orders are sent direct from distribution to the recipient.  To sign up on line as a distributor click on this link:
