Uptime Energy, Bawls Guarana, Amp Energy Zero, and V8 + Energy: May Recap of Quick Reviews – Science of Energy Drinks

greeneyedguide

Here’s a recap of the quick reviews posted this month for the “Science of Energy Drinks” series on the GreenEyedGuide Instagram and Facebook pages: Uptime Energy, Bawls Guarana, Amp Energy Zero, and V8 + Energy.

 

 

uptime energy

Science Behind Uptime Energy drink: 3-Ingredients to Focus on:

⛾1-Angelica Root Ext (aka Danggui) is used for female reproductive disorders in Traditional Chinese Medicine. After 15 minutes on Pubmed & SciDirect I DON’T KNOW WHY it’s in here. (Dear science nerds, please help if you do).
⛾2-Bee Pollen has vitamins, polyphenols, and enzymes, and has shown health benefits in studies but ONLY WHEN USED IN GRAM AMOUNTS! This product’s whole “Power Base” combined is only 20% of a gram. [1 gram = weight of 1 paperclip].
⛾3-Caffeine is the only ingredient that (kind of) “produces energy” but this bugs me. (#stickler #rant #chemnerd) There’s 142 mg caffeine in here = ALMOST a Monster (160mg).

bawls guarana energy

LET’S TALK ABOUT GUARANA. BAWLS Ingredients include caffeine, HFCS, citric acid, sodium benzoate, natural AND artificial flavor, caramel color. No B-vitamins, taurine, carnitine, or other stereotypical energy drink ingredients.

CAFFEINE CONTENT: from guarana and pure caffeine; 100mg Caffeine per can from all sources, according to the CAFFEINE INFORMER database. That’s LESS caffeine than 12 oz Red Bull (114 mg). The limit for those under 18yrs old is 100mg.

GUARANA is a vine from the rainforest bearing orange-red fruit with black seeds. Caffeine is in the seeds. Multiple studies show guarana improves cognitive performance, mental fatigue, and mood, and it is supposed to boost fat metabolism by encouraging the body to burn fat instead of protein and carbs. HOWEVER, the same benefits are true of caffeine in general and caffeine from green tea in particular. So these benefits are not specific to guarana… and this product gives you 50g sugar per can.

PART ONE: WHAT DOES EDTA DO?
EDTA, Sodium benzoate, and Sodium hexametaphosphate: All 3 are in this drink. Does a canned drink need so much preservation?
1. EDTA: the ingredient statement says “to protect flavor”…from WHAT? From metal ions of the can, which can oxidize and degrade the natural+artificial flavor and the B-vitamins.
PURPOSE: Chelating agent, meaning it binds metal ions to limit their deleterious effects; EDTA stabilizes food color, aroma, texture, inhibits oxidation of fats, oils.
SAFETY NOTES: Some sources say EDTA “robs the body of nutrients” but EDTA is safe to consume **up to 3 grams per day **and AMOUNTS USED IN FOOD are in the milligram per kilogram or parts-per-million range. CPSI puts this in the “Safe” column.
***FUN FACT: EDTA is actually used to treat people with heavy metal poisoning because EDTA can grab the heavy metals and escort them out of the body.

PART 2 of Amp Preservative review: WHAT does Sodium benzoate do?
Sodium Benzoate: “preserves freshness”… but it’s not like this is a fresh ripe watermelon right? Well, this IS an acidic drink…
PURPOSE: Prevents growth of microorganisms like yeast and mold; used for preservation of sour food pH 4 and lower, often used with other preservatives especially at low pH (meaning acidic food).
SAFETY NOTES: Consumers can ingest up to 5mg per kg of body weight of benzoic acid and its salts
***FUN FACT: Benzoic acid occurs naturally in cranberries, prunes, plums, cinnamon, ripe cloves, and most berries. http://wp.me/p3SHzu-It

PART 3 of AMP preservative review: “Hexa-meta-huh?”
3. Sodium hexametaphosphate: “to protect flavor”… YOU’D THINK AMP’S FLAVOR IS LIKE GOLD with all this PROTECTION!!!
SAFETY NOTES: This ingredient is widely accepted as safe in many countries. It has the additive number E452. In controlled studies, it was not carcinogenic in rats, nor did it cause any reproductive or developmental toxicity symptoms. It’s fine if you consume a little bit every now and then, but consuming it regularly can have some negative effects due to mineral imbalances. MODERATION IS KEY!

v8 plus energy

Energy drinks are dangerous, right? V8 Energy, busting stereotypes since 2011! The caffeine in V8 Energy comes from green tea extract which provides a natural lift as well as the amino acid L-theanine which is believed to provide added focus. [CaffeineInformer.com]
🔹️L-theanine can reduce anxiety and blood pressure increases in high-stress individuals (ie people more susceptible to biological changes when stressed)
🔹️This can contains 80 mg caffeine (as much as Red Bull) BUT…
🔹️ the Academy of Pediatrics says people <18 can have UP TO 100 mg caffeine per day.
🔹️With 34% juice, only 11 grams of sugar, and caffeine from green tea extract, this is one of the BEST healthy alternatives!

Thiamin and Carbohydrate Metabolism – Book Excerpt of the Week

Thiamin and Carbohydrate Metabolism – Book Excerpt of the Week

greeneyedguide

Last week we talked about how some energy drinks have B-vitamins, but not all B-vitamins are relevant to the way the body generates energy. If the B-vitamins were the Avengers, then Thiamin would definitely be one of the strongest members. Thiamin is a crucial part of how the body turns glucose into energy.

Glucose is the most basic unit of a carbohydrate and the preferred fuel for the body. As a glucose molecule is broken down to release energy it must become a molecule/metabolite named pyruvate. Thiamin (as its coenzyme form, thiamin pyrophosphate or TPP) keeps that enzyme humming like a well-oiled machine. So without sufficient thiamin, carbohydrate metabolism screeches to a halt. Thiamin as TPP participates in the metabolism of fat, protein, and nucleic acids, but it’s carbohydrate metabolism that’s first to go haywire with a thiamin deficiency.

Stay tuned as we look at other B-vitamins in our page-by-page tour through my book on the science of energy drinks and their ingredients.
