Natural Source Vitamins Vs Synthetic
Bioavailability vs..: Bioavailability may vary depending on the source of your vitamin supplement. Potency and purity however play significant roles in the efficacy of the supplement, regardless of source. Find the cheapest vitamin that approaches 100% rdu (recommended daily allowance) and save money over "natural source" ones. There are of course significant benefits from eating healthy foods in general. ...Read more
Synthetic vs Natural Plant based multivitamin, which should I take and which is better? Is synthetic harmful?
Is the nutritional supplement Ultra Potent-C®, made by Metagenics, bioequivalent to vitamin C from food sources?
Chemistry: Any thing, vitamin, drug, rock, is a chemical substance with a distinct structure That structure can occur naturally or be made in a lab or factory. Vitamin C is still Vitamin C. However, taking vitamins does not seem to make up for a bad diet lacking in fruits and veggies. It is better to get vitamins in the proper foods because more than the just adequate vitamin intake is involved in fitness. ...Read more
Same chemical but...: Both natural & synthetic vit. C are the same chemical, ascorbic acid, so most feel there's no difference but most synthetic is from gmo corn, which i feel is wise to avoid. Natural c usually has beneficial flavonoids too. See http://vitamincfoundation.Org/naturalc.Htm for the argument that there is essentially no difference & see comment for link to the argument in favor of natural vit c. ...Read more
No better or worse: When it comes to multivitamins & mineral supplements, you don't need fancy labels & brands. Yes, there are claims re solubility etc but bottom line, there aren't even any studies showing clinical benefit from multivtamins. With that said, rather than worry about brand names & labels (aside from USP DSVP), ask your family doc to measure 25OH vitamin D. Keep it over 30ng/mL to protect your bones. ...Read more
Depends: Many multivitamins have too much iron and copper in them. Copper and zinc should be in balance, and are competitively absorbed. Many people already have enough copper and insufficient zinc, therefore a supplement with copper is often undesired. Iron can be an oxidative stress on the body, and we do not supplement it unless clearly needed. So read the label to decide. ...Read moreSee 1 more doctor answer
Yes: There seems to be but many varying opinions on the efficacy. I would check reviews and research the product to hopefully get some answers. ...Read more
Neither: Depends on who makes it for them as neither makes their own. You need "mixed tocopherols" to benefit your health not just vit e which is usually just one form of the many and is a synthetic which is cheaper but can lead to bad outcomes. I use pure encapsulations brand, other good quality ones are from orthomolecular, metagenics. Read label and remember you get what you pay for! ...Read more
Is the ingredients mention below suitable for pregnant woman 1) Collagen peptide 2) perilla seed extract 3) silk protein 4) soy isolfavone?
Forget this stuff.: Take your prenatal vitamins, folic acid, calcium and Vit. D and nothing else. All of those products are poorly studied and there is very little responsible, independent testing to determine if they actually work or if they may have side effects, or harm fetuses. Also the companies have different ways of making up these pills. Save your money and spend it on plenty of fruits and veggies instead. ...Read more
Is it safe to use to 100% natural products? (like products which claim to have coconut & other plant-derived ingredients instead of synthetic ones)
Natural products: can lower the probability of illness but are no guarantee against health problems. Please think holistically. Look at your lifestyle. Do you exercise, get enough rest, etc. All of this helps. Peace and good health. ...Read more
Multivitamins: are like an insurance policy for when we don't eat right, don't sleep well, or are especially stressed. Go to a good store or get some guidance because the popular brands are typically very week and not helpful. The dose (read label and check that half or more of the ingredients are several 100 per cent above RDA. Dose more important than a long list. Ask about a specific condition or supplement ...Read more

Many companies: Many companies make good vitamin d3 products -- there is no one "best." the seal "usp verified ingredients" on the label may help. Or if the company uses "gmp" standards. Depending on your preferences, you may want a source free of gluten, dairy, etc. Labels will tell you that information also. Consumerlab shares some reliable info on specific products: http://www.Consumerlab.Com. ...Read more
Is it recommended to take a multi vitamin? And is true that some synthetic supplements like folic acid are better in synthetic form than from greens?

Certain vitamins are needed to take if you are deficient in a specific vitamin. For good health i recommend omega 3 and antioxidants, they have many benefits. ...Read more

Do all fortified foods contain cyanocobalamin or do some contain methyl or hydroxo, and which natural sources of b12, are the most bioavailable?
Most cyanocobalamin: No way of knowing if "all" have the cyano form but I believe virtually all have that form as it is the least expensive and most widely available. But methylcobalamin is the optimal form for supplementation- see http://tinyurl.com/h7scsna Some foods contain higher concentrations of B12 but the form found in food is hydoxycobalamin so all equally bioavailable. See http://tinyurl.com/j7npwg3 ...Read more
Is there any brand in market that sells b-carotine derived vitamin A, instead of fish oil derived vitamin A? Fish oil gives me anxiety.
No,but not necessary: I'm not aware of any preformed Vit A supps from vegan sources, but this isn't necessary as we can convert beta carotene to Vit A. Some people do this more efficiently than others but everyone does it to some degree so if you eat enough food rich in beta carotene or take it as a supp. you'll get adequate A. Dairy also contains A.Even if fish oil gives anxiety,A derived from fish oil probably won't. ...Read more
