About this product

Niacinamide contributes some B3 without the usual nicotinic-acid flush. The formula's main purpose is pre-workout stimulation and thermogenic support, not correcting niacin intake.

A proprietary thermogenic blend hides individual ingredient amounts. That gap makes it difficult to judge the strength of the combined stimulants or anticipate tolerance.

The strawberry-watermelon powder may appeal to experienced users who specifically want the full pre-workout profile. A single-ingredient product is a clearer choice for anyone whose actual goal is niacin supplementation.

Who is it for
  • Experienced adults seeking a flavored pre-workout
  • Users comfortable with a proprietary thermogenic blend
Best for
  • Pre-workout use rather than B3 nutrition
  • Stimulant-oriented routines

Pros

  • Niacinamide has low classic flush potential
  • Flavored drink format
  • Some performance ingredients are disclosed

Cons

  • Thermogenic blend amounts are hidden
  • Poor value as a niacin source
  • Unrelated complexity for B3 supplementation

Warnings

  • Proprietary thermogenic dosing makes stimulant tolerance difficult to predict
  • Do not casually stack it with caffeine or other thermogenic products
  • People sensitive to stimulants may find the broader formula unsuitable

Product analysis

57 out of 100
A little low-flush niacinamide does not offset the opaque thermogenic blend or the formula's poor fit for focused B3 use.

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

Nutrient quality74

Several performance actives use specific and well-regarded forms, including CarnoSyn and Nitrosigine. Citrulline malate, beta-alanine, betaine, taurine, and Nitrosigine have substantial amounts.

.
Ingredient transparency54

Major performance actives are quantified, but the thermogenic matrix has no internal doses. The flavoring, sweeteners, carriers, and complete inactive ingredient list were not supplied.

.
Customer satisfaction62

The available aggregate rating is reasonably strong for this category. No firsthand outcome details were supplied, so alignment with the intended use is uncertain.

.
Value for money35

Meaningful performance doses add quality, but the hidden matrix weakens price justification. The product is less competitive than transparent pre-workouts with lower serving costs.

82 Performance

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. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
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. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
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. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
85 Budget

Niacin 100 mg

Source Naturals
Clearly identified niacinamide provides a moderate, economical vitamin B3 serving with little classic flushing risk. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
80 Budget

Super Vitamin B-Complex

Spring Valley
Broad measured B-vitamin coverage offers strong value, though unspecified chemical forms and unnecessarily high thiamine limit refinement. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
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. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
82 Value

Niacin 100 mg

Nature's Way
Clearly identified immediate-release nicotinic acid provides a modest and inexpensive niacin serving, but temporary flushing remains likely. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
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. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
80 Value

No-Flush Niacin (Inositol Hexanicotinate) 500 mg

Solgar
Inositol hexanicotinate provides clearly named no-flush niacin exposure with practical value, while its effects may be less direct than nicotinic acid. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
