Is Shaka Tea Healthy? Discover the Power of this Nourishing Beverage

Say you have high blood pressure and drink two bottles of Shaka Tea a day. The hibiscus could drop your pressure further than your medication intends. That’s why the health answer depends on which blend you pick and what else you take.
Shaka Tea is a Hawaiian herbal infusion, usually hibiscus, mamaki, lemongrass, and ginger. The unsweetened line is the one worth reaching for. The sweetened or fruit-juice blends are a different drink.
Is Shaka Tea Healthy? The Quick Answer
Shaka Tea is healthy for most people as a zero-calorie, unsweetened herbal drink, though hibiscus lovers on blood pressure medication should cap it at about 2 cups (16 oz) a day. The reason: hibiscus contains anthocyanins that relax blood vessels, which can drop your blood pressure a few points. That’s great if your pressure runs high, but it can stack with antihypertensive drugs and leave you dizzy.
The core line is genuinely clean: a 16 oz bottle has 0 calories and no added sugar. Most flavors are caffeine-free, so they won’t keep you up or spike your heart rate. Just check the label if you pick a blend with green or black tea, because those add caffeine.
Unsweetened black iced tea is healthy for the same reason: no sugar, no calories, and a dose of plant compounds. The catch is the caffeine, which lands around 40-50 mg per 8 oz. Unsweetened iced tea in general is a smart swap for soda, but herbal versions like Shaka give you the benefits without the buzz.
Check the Label for Added Sugar
Shaka Tea is only healthy when you pick the unsweetened bottle. The label should read 0g added sugar and 0 calories. Some flavors sneak in fruit juice concentrate or honey, which turns a zero-sugar drink into something closer to soda.
A 16 oz sweetened tea can pack 20-30g of sugar. For reference, the daily added sugar limit is about 25g for women and 36g for men. One bottle can blow the whole day’s budget.
| Unsweetened Shaka Tea | Sweetened tea (typical) |
|---|---|
| Calories per 16 oz | 0 |
| Added sugar | 0g |
| Ingredients | Hibiscus, water, natural flavors |
No-sugar iced tea is healthy precisely because it skips the sweet stuff. Drinking tea without sugar, black or herbal, keeps your blood sugar steady and your calorie count low. It’s one of the easiest swaps you can make.
Who Should Limit Shaka Tea
Hibiscus tea is a safe daily drink for most healthy adults, but a few groups should cap it or skip it. One 16 oz bottle of Shaka Tea counts as about 2 cups of brewed hibiscus tea.
If you take blood pressure medication, check with your pharmacist before making hibiscus a daily habit. Hibiscus can lower blood pressure on its own, and the combination may drop yours too low. A safe healthy blood pressure tea for most people on medication is one that doesn’t add a second blood-pressure-lowering effect, like plain green tea or chamomile.
Healthy tea blood pressure benefits come from hibiscus anthocyanins, but the effect is modest. If your doctor has told you to keep your blood pressure steady, don’t use Shaka Tea as a substitute for medication or a reason to skip a reading.
Pregnant women should limit hibiscus to 1 cup (8 oz) a day or avoid it. Traditional use suggests hibiscus may stimulate menstruation, and safety data in pregnancy is thin. Talk with your OB before drinking it regularly.
Kidney stone formers need to watch hibiscus because it’s high in oxalates. If you’ve had calcium oxalate stones, a daily 16 oz bottle adds a meaningful oxalate load. Ask your nephrologist whether hibiscus fits your daily limit.
Anyone with a known hibiscus allergy should avoid Shaka Tea entirely. Reactions are rare but can include itching, hives, or swelling of the mouth or throat.
Your care team’s advice overrides general guidance. If your cardiologist, OB or dietitian gave you a specific tea limit, follow that number.

Drinking unsweetened Shaka Tea every day is healthy for most people, but side effects show up when you pass about 3 cups (24 oz) daily. The main ones are low blood pressure, stomach irritation, and a higher oxalate load.
Low blood pressure is the most common complaint. At 3 or more cups a day, hibiscus can make your blood pressure dip enough to cause dizziness, lightheadedness or fainting when you stand up. That risk rises if you take a diuretic or blood pressure pill.
Hibiscus is acidic, with a pH around 2.5 to 3.5, similar to lemon juice. If you have reflux or gastritis, a 16 oz bottle on an empty stomach can trigger heartburn or stomach pain. Drinking it with food or diluting it with water helps.
Kidney stones become a concern with daily high intake. Hibiscus is rich in oxalates, and consistently drinking more than about 3 cups a day raises the oxalate load in your urine. For most people that’s harmless, but if you’ve passed a calcium oxalate stone before, cap hibiscus at 1 to 2 cups a day.
Hibiscus can also enhance the effect of blood pressure drugs and diuretics. That’s not a reason to stop your medication; it’s a reason to keep your tea intake steady and tell your doctor how much you actually drink.
Is drinking unsweetened black iced tea healthy? Yes, and it’s a lower-oxalate swap if hibiscus bothers your stomach or kidneys. Black tea has about one-tenth the oxalate of hibiscus per cup.
Moringa Tea: A More Nutrient-Dense Alternative
Hibiscus gives you antioxidants, but moringa leaves pack a wider spread of nutrients into each cup. A single tea bag contains over 93 nutrients: 48 antioxidants, 27 vitamins and minerals, and all 9 essential amino acids. That’s a broader profile than a typical hibiscus infusion, which is why some people rotate the two.
If you’re asking whether David’s Tea or Tetley healthy tea options compare, the answer depends on the blend. Unsweetened herbal teas from those brands can be fine, but they won’t automatically match moringa’s nutrient density. Check the label for added sugar and artificial flavors.

| Per 8 oz brewed tea | Shaka Tea (hibiscus) | Moringa Turmeric Ginger |
|---|---|---|
| Calories | 0 | 0 |
| Added sugar | 0 g | 0 g |
| Caffeine | 0 mg | 0 mg |
| Key nutrients | Antioxidants, vitamin C | 93+ nutrients, 9 essential amino acids |
| Anti-inflammatory compounds | Some from hibiscus | Curcumin (turmeric), gingerols |
Brew moringa at 175°F, not boiling, to preserve delicate vitamins. A 3-minute steep keeps the taste mild; longer releases more nutrients but also more bitterness.
How to Brew Herbal Tea for Maximum Benefit
Water temperature decides whether your cup stays smooth or turns bitter. Bring water to 175°F, not a full boil, for delicate herbs like hibiscus and moringa. Boiling water scalds the leaves and can destroy some heat-sensitive vitamins.
Unsweetened black iced tea is healthy, and a fountain unsweet tea can be too, but check that the dispenser isn’t cross-mixing with a sweetened line. Rotate herbal teas through the week so you’re not overexposed to any single herb.
If you want to branch out beyond hibiscus, hojicha tea offers a roasted, low-caffeine option, and almond tea brings a nutty, caffeine-free alternative. Both brew well with the same gentle method.
