Bob says Flow kept him steady through a five-hour high-cognitive-stress day without caffeine.

1. Inside Sports Nutrition Ep. #224 reviews Oomph Flow, a caffeine-free non-stimulant pre-workout. 2. Dena Griffin and Bob Sibahar host the show, and both are registered dietitians and board certified specialists in sports dietetics. 3. The episode tests whether Flow is meant for cognitive focus, hydration support, and performance instead of a caffeine rush. 4. Bob says he sees pre-workout questions every day and calls the category the “Wild West.” 5. Dena says the label uses line-item doses rather than a proprietary blend, which she says makes the formulation easier to evaluate. 6. The product carries Informed Sport certification, which Bob says matters for athletes who may be drug tested. 7. The label highlights 820 milligrams of sodium, which the hosts say may be high for some athletes. 8. The formula includes 415 milligrams of beetroot nitrates, and Bob links that ingredient to vasodilation and oxygen delivery. 9. Rhodiola rosea appears at 400 milligrams, and Dena describes it as an adaptogen associated with mental focus. 10. Lion's mane is included at 1,000 milligrams, and the hosts connect it to cognitive functioning and mental energy. 11. Bob says the brand recommends taking Flow two to three hours before training, not 30 to 60 minutes like a stimulant pre-workout. 12. Dena notes that the product is sweetened with stevia extract and mixes best in at least 16 ounces of water. 13. Bob says the watermelon flavor felt better to him than lemon-lime, and he preferred a larger 24-ounce shaker bottle. 14. On a technical 10-mile trail run, Bob says he noticed better foot placement and body awareness. 15. On a separate five-hour day of continuous cognitive work, Bob says he felt steady without coffee, matcha, or other caffeine. 16. Bob says the product felt more useful in the high-cognitive-stress setting than during exercise, where adrenaline can blur the effect. 17. The tone is conversational and evaluative, with Dena asking follow-up questions and Bob giving end-of-one testing notes. 18. The format mixes product review, sports nutrition education, and personal trial observations rather than a formal interview. 19. Endurance athletes, coaches, and supplement-conscious competitors may get the most from this episode. 20. Listeners wanting entertainment or narrative storytelling may skip it.
