AI assessment of the formula, label and price. How scoring works

Nutrient Quality20

The ingredient-form declaration is incomplete, limiting a confident quality comparison. The amount alone does not resolve that uncertainty.

Ingredient Transparency63

The niacin amount is disclosed, helping you compare servings. The specific form is not fully disclosed, leaving less clarity about the preparation.

Value For Money100

The serving cost compares favorably for the niacin content. The single-ingredient formula makes that value comparison straightforward.

Customer Satisfaction83

Customer feedback is very positive across more than a thousand ratings. The larger feedback base describes satisfaction without establishing a particular health effect.

Product Focus40

The single-vitamin formula has a clear niacin focus. A particular health benefit cannot be established from the available detail.

Sustained-Release Niacin with niaXtend 500 mg

Doctor's Best
Sustained-release nicotinic acid provides a clearly named form and controlled delivery, though the high amount still carries liver-related risk and needs safety guidance. The original already offers a moderate, clearly identified non-flushing dose, so this alternative is useful only when its different form, amount, or broader profile is specifically wanted.
82 Performance

No Flush Niacin (Inositol Hexanicotinate) 800 mg

Life Extension
Clearly named inositol hexanicotinate supports comfort-focused niacin use with less flushing, but its cardiovascular effects may be less direct than nicotinic acid. The original already offers a moderate, clearly identified non-flushing dose, so this alternative is useful only when its different form, amount, or broader profile is specifically wanted.
80 Performance

Niacinamide

Thorne
Niacinamide offers a clearly identified non-flushing form suited to NAD metabolism and skin-related use, although the amount is high for routine nutrition. The original already offers a moderate, clearly identified non-flushing dose, so this alternative is useful only when its different form, amount, or broader profile is specifically wanted.

Niacin 100 mg

Source Naturals
Clearly identified niacinamide provides a moderate, economical vitamin B3 serving with little classic flushing risk.

Super Vitamin B-Complex

Spring Valley
Broad measured B-vitamin coverage offers strong value, though unspecified chemical forms and unnecessarily high thiamine limit refinement. The original already offers a moderate, clearly identified non-flushing dose, so this alternative is useful only when its different form, amount, or broader profile is specifically wanted.
81 Budget

B-Complex with Folic Acid plus Vitamin C

Nature's Bounty
A broad B-complex with vitamin C provides low-cost daily coverage, while conventional forms and duplicated thiamine entries reduce form quality. The original already offers a moderate, clearly identified non-flushing dose, so this alternative is useful only when its different form, amount, or broader profile is specifically wanted.

Niacin 100 mg

Nature's Way
Clearly identified immediate-release nicotinic acid provides a modest and inexpensive niacin serving, but temporary flushing remains likely. The original already offers a moderate, clearly identified non-flushing dose, so this alternative is useful only when its different form, amount, or broader profile is specifically wanted.
80 Value

Niacinamide 500 mg

21st Century
A simple non-flushing niacinamide formula offers strong serving value, though the amount is well above basic nutritional needs. The original already offers a moderate, clearly identified non-flushing dose, so this alternative is useful only when its different form, amount, or broader profile is specifically wanted.
