B Right 100 Veggie Caps Low Odor Vitamin B Complex Formula Energy & Metabolism Support Promotes Brain, Heart & Cardiovascular Health 100 Servings, White, 100 Count (Pack of 1)

This is the only B Complex that doesn't upset my stomach. Glad to have read other's reviews letting me know that. Need B's for energy.

肌の調子が良いです。自分にあってるみたいで良いです。また、買いたいです。

This is the best and the cheapest optimised B-complex on the market. It contains methyl-B12 (-CH3) rather than the cheaper and more stable cyano-B12 (-CN). N.B. Cyanide-B12 makes a lot of people feel unwell: Did you know B12 is an antidote to cyanide poisoning? BTW: A lot of people need more methyl groups to improve methylation. As a result methyl-B12 increases energy... while CN-B12 decreases energy i.e. Makes you feel bad Unfortunately CH3-B12 has a shorter shelf life than CN-B12... but that's not an issue if you have used up all the tablets within the normal expiry date (about 1 year) The formula also contains folate (the active form of B9) rather than folic acid (the inactive form) . Jarrow keep fiddling with the niacin in this formulation: It is currently nicotinic acid but has been inositol hexanicotinate (IH) in the past. The amount in the formula seems to keep changing too. This is probably because Niacin (B3) causes an uncomfortable flush and many customers complain. The IH form is preferable to avoid/reduce flushing... and it allows higher amounts to be taken. 100 mg would be a more useful dose... as it would reduce the need to take extra niacin. The bottle contains 100 tablets... which is OK... but a bigger bottle (200) would suit most families better. Otherwise you end up with a big pile of empties very quickly. If you're uncertain about B-complex formulations this is the one to try. :-) P.S. Hydroxy-B12 could be used in this formulation to increase shelf life. OH-B12 is a very pleasant and is well tolerated by anyone who finds CN-B12 unpleasant.

I've been taking this B Complex for a couple years now, and it's the best Vitamin B Complex I've ever taken. High quality ingredients that make for the best absorption. I never had any problems with "niacin flush" like some other reviews have talked about. There is evidence of having more energy because I noticed I don't need a nap on the days I take this.

This is the right B complex for everyone that has the methyl b12 ingredient and not the cyanocobalamin cheap ingredient which contains a cyanide molecule. Most people are familiar with cyanide as a poisonous substance. Although the amount of cyanide in a normal B12 supplement is small and from a toxicology point, viewed as insignificant, your body will still need to remove and eliminate this compound.Compared with cyanocobalamin, it appears that methylcobalamin is better absorbed and retained in higher amounts within your tissues. In simple terms, they are used much more effectively. In general, methylcobalamin is used primarily in your liver, brain, and nervous system. Methylcobalamin is the specific form of B12 needed for nervous system health. Because of this, it should be the first form of this vitamin thought of when interested in attempting to optimize the health of the nervous system with vitamin supplementation. Indications of a potential deficiency of B12 in the nervous system might include numbness, tingling, loss of feeling sensation, burning sensations, muscle cramps, nerve pain and slowness of reflexes. Because of methylcobalamin's importance in nervous system health, it is also an important nutrient for vision. In fact, continued visual work (like work on a computer) often leads to a reduction in something called "visual accommodation". Methylcobalamin can significantly improve visual accommodation, while cyanocobalamin appears to be ineffective. An elevated level of homocysteine is a metabolic indication of decreased levels of the coenzyme forms of vitamin B12, especially methylcobalamin. Homocysteine has received a tremendous amount of emphasis in the scientific literature because of its associations with heart disease and a variety of other specific health conditions. I have even seen advertisements on television promoting folic acid, as a vitamin needed to lower homocysteine. While this is true, and folic acid does lower homocysteine levels, the combination of methylcobalamin and folic acid appears to work much better. The most well-studied use of methylcobalamin has to do with sleep. Although the exact mechanism of action is not yet clear, it is possible that methylcobalamin is needed for the synthesis of melatonin. Available information indicates that methylcobalamin can modulate melatonin secretion, enhance light-sensitivity, and normalize circadian rhythm (your 24-hour clock). Because of this, individuals supplementing this form of B12 often have improved quality of sleep, often will require slightly less sleep, and will not uncommonly report that they feel a bit more refreshed when waking in the morning. Methylcobalamin is particularly effective when your 24-hour clock is not running smoothly. This may be indicated by a need for excessive sleep, changing sleep-wake cycles, or a tendency to have altered sleep-wake patterns. As examples, you might require 10-12 hours of sleep, or you might not feel tired until 2-3 am and you might wake at noon, or you might find that you wake a bit later every day and go to be a bit later every night. Under all of these circumstances, the combination of methylcobalamin (about 3000 mcg daily) and exposure to bright light in the morning can help reestablish your 24-hour clock. Because of methylcobalamin's impact on 24-hour clock and the cycles that feed of this, it is also an important vitamin to regulate your 24-hour release of the stress hormone cortisol. This seems to be particularly important for blood types A and AB. Methylcobalamin also seems to result in a better 24-hour maintenance of body temperature. Typically individuals supplementing this coenzyme form of B12 have higher temperatures in the later hours of the daytime. This usually corresponds with improved alertness at the same time of the day. While this can be of importance for all blood types, low body temperatures seems to be an area of greater challenge for A's and B's.),
